See Why Most Parents Prefer Hiring Online Math Tutors
Hiring a math tutor who offers their services online is a great step forward for any parent who wants their children to become math heroes. As long as your child has a computer, they can get tutorial lessons from their online math tutors no matter where they are located. Many people have confirmed how effective the online math tutorial services are since they have transformed their children in this subject. Of importance is making sure you get an online math tutor who has been in the online tutorial industry for some time, and they understand the subject in and out.
One important thing to know is that students at any place across the globe can get the quality math tutorial services they need at any time. The online math tutors can offer services at different levels whether at the college level or early elementary level. One important aspect of any online math tutor is to know their grade level or area of focus on this subject. It is good to know that many online tutors know the best methodologies to use but this comes after they analyze the student’s capabilities and needs.
If all children were to study mathematics from their classroom, most of the lessons would be chaotic, and the online lessons have come to prevent this. Besides being convenient, getting an online tutor for your child is also safer. Although taking a child for tutorial lessons to a local center may be cheaper, most parents may not have time to take or pick them there. Hiring a tutor to teach your child at home may not a good option especially if the tutor you hire isn’t dependable and trustworthy.
When you see many people taking the online tutorial services seriously, it’s because they know how reliable and efficient they are compared to other learning methods. No matter the remote location of the tutor, the students would still receive quality tutorial lessons and learn a lot. The computer would help the math students to receive answers from their tutors, ask some burning questions, and get the crucial information they need.
You can always be assured that your children would receive standard education services from the online tutors. The good thing with these online tutors is that they know how to address the needs of their students at whatever level. The online tutors make schedules that allow students to learn at home with all the comfort they need. Most online tutors have made their tutorials exciting through interactive technology.

The function planewall_Q_ND(Fo, Bi) returns the non-dimensional heat transfer to a bounded plane wall with one edge exposed to convection (x=L) and the other adiabatic (x=0). The supplied values, Fo, Bi represent the Fourier number and Biot number respectively. The non-dimensional heat transfer is the ratio of the actual to the maximum heat transfer into the wall. A separation of variables technique is used to solve for the temperature, as explained in section 3.5.2 of Nellis and Klein.

Still remember the lesson I made about numbers in Japanese?
Well, I said that the number 0 also has a kanji, and here it is!
It is pronounced れい (rei), and as I said, it is not that used to represent the number 0.
It is used in words like 零下 (reika – below zero), 零細 (reisai – insignificant), or 零時 (reiji – 12 o’clock).
Kind of a mysterious kanji…

The mathematics curriculum has been developed in line with the English National Curriculum to ensure that the children receive a thorough grounding in basic mathematical skills and concepts. Early mathematical experiences lay the foundation for future expertise. Through imaginative, differentiated and practical activities, children will find a great deal of enjoyment in their learning, as well as appreciating the importance of mathematics.
Mathematics at all levels will include discussions, manipulation of concrete materials, investigations, problem solving, practice and consolidation, and mental maths. The mathematics curriculum can be divided into four main strands:


Computes statistics such as mean (average), minimum, maximum, and standard deviation (±) over a selected area on the map for the displayed overlay. Click twice on the map to select opposite corners of a bounding box. Click on the center marker that results to produce a pop-up window with the computed statistics. The edges and corners of the bounding box can be further adjusted or the center marker can be dragged to a new location. You can also enter or refine the vertices of the bounding box using the min/max lat/lon inputs below in decimal degrees.
NOTE: Statistics are computed only for the pixels whose center points are contained in the selected bounding box. In the illustration below, only the pixels numbered #1-9 will be used to compute the area statistics for the yellow selection box while those labeled "x" are excluded:


Garden Area Calculator
1Determine How Many Square Feet You Have:
To determine how many square feet you have, you will use the formulas listed below to find area (A) - this mathematical formula will be different based on the shape of your garden. First, you will need to go outside and measure your garden bed. You will need to have the proper measurements handy, such as width (W), length (L), radius (R), base (B), or height (H).
A rectangle and square both have four right angles. The area of a rectangle or square is found by multiplying the length (L) by the width (W).
A circle is a closed curve of which every point on the edge of the curve is the same distance from the center point. The area of a circle is the radius squared (R)x(R) multiplied by pi (~3.14). The radius is equal to one-half the diameter of the circle.
Oval Shaped Garden
An oval has an elliptical, or egg-like, shape. The area of an oval is the length (L) multiplied by the width (W), multiplied by 0.8.
A triangle is a polygon with three sides. The area of a triangle is one-half the base (B) multiplied by the height (H).
Irregularly Shaped Garden
To find the area of a large irregular shape, divide it into a series of smaller units equally spaced along a measured line. This method will calculate the area to within 5%.
- Determine the length line. This is the longest axis of the shape as shown in the image from point A to point B.
- Mark width lines along the A-B line into several segments of equal width. To ensure accuracy, use as many width lines as possible. The more irregular the shape, the more width lines you will need.
- Measure the width at each width line. In this example, there are 5 width lines: C, D, E, F and G.
- Calculate the area by adding all of the width lines together and multiplying the total by the distance between each line (C+D+E+F+G) x Segment Width.
2Decide How Many Bulbs You Need
Now that you know how many square feet you have, you will now determine how many bulbs you need to fill it! Use the table below to calculate how many bulbs you need per square feet. Multilply your square feet (sq ft) by the number of bulbs (# of bulbs) for your total number of bulbs needed. For example: If your garden is 10 square feet and you want to fill it with tulips, you will multiply: 10 (sq feet) x 5 (# of bulbs) to equal 50.


Version 1.10.8, 2014-04-10
- Fix a bug in primality testing introduced in 1.8.3 which caused only
a single random base, rather than a sequence of random bases, to be
used in the Miller-Rabin test. This increased the probability that a
non-prime would be accepted, for instance a 1024 bit number would be
incorrectly classed as prime with probability around 2^-40. Reported
by Jeff Marrison.
- The key length limit on HMAC has been raised to 512 bytes, allowing
the use of very long passphrases with PBKDF2.


The Cm software implements the construction of ring class fields of imaginary quadratic number fields and of elliptic curves with complex multiplication via floating point approximations. It consists of libraries that can be called from within a C program and of executable command line applications. For the implemented algorithms, see A. Enge, The complexity of class polynomial computation via floating point approximations, Mathematics of Computation 78 (266), 2009, pp. 1089–1107.
- The baby-step giant-step algorithm of Enge-Hart-Johansson 2016 is used to compute the series of η, leading to a speed-up of up to a factor of 2 for this step of the algorithm.
- Class polynomial computation for j and γ2 is sped up by using a 2- or a 6-system, respectively, instead of a 1- or a 3-system. This makes it more likely that during the needed computation of η (τ/2) the conductor is not changed, so that a precomputed η value may be reused.
- The license has been updated to GPLv3+, in line with the license of recent Gmp, Mpfr and Mpc releases.
Version 0.2.1 "Blindhühnchen", released in March 2015, comes with the following new features:
- Precisions beyond 300000 bits are now supported by an addition chain of variable length for the η-function.
- The minimal version number of Mpfr has been increased to 3.0.0, that of Mpc to 1.0.0 and that of Pari to 2.7.0.
Version 0.2, released in February 2012, comes with the following new features:
new class invariants: multiple eta quotients with
- double eta quotients with both primes >100
- new parameter choice for double eta quotients yielding smaller class polynomials
- slightly lower height bounds for double eta quotients
- new class invariants: multiple eta quotients with
printing of field and curve cardinality even without parameter
Weber polynomials work again (activated by
- class polynomials for D=-4 and D=-16 work (no curve is constructed)
- printing of field and curve cardinality even without parameter

The initial release of version 0.1 "Apfelkraut" was made in November 2009.


Little Miss Kindergarten is hosting a linky party for sharing your Calendar Walls.
This past school year (2010-2011) I set up 2 classrooms. I started teaching 1st grade at one school and 5 days into the school year I was displaced. I had to switch schools and grade levels. I ended up teaching Kindergarten at a different school in my district (which I LOVE).
Pictures 1 and 2 show my calendar area in my Kindergarten classroom. I have a pocket chart calendar, it's wonderful and easy to use. I use calendar cover-ups from Creative Teaching Press. They are bright, colorful and create a different pattern for each month. The calendar set I have came with weather cards, and I found a "Today Is_______" set at the Dollar Tree.
We start off Calendar by singing our "Days of the Week" song and "Macarena Months" (both by Dr. Jean), then I pull out name sticks to choose kiddos to come up and help. The helpers get to do jobs like tell us what number comes next, what the pattern is, pick actions to show the pattern, fix the days of the week, choose the type of voice we will say the date in etc. We also count the number of days we have been in school by adding a number to our number line, a straw to our place value pockets, tally marks, and money. We also dance, sing and count by 1's, 5's, 10's and 2's.
Picture 3 shows my calendar area in my 1st grade room. We had the same basic routine, except the kiddos ran calendar, we also did "number collections" (different ways to make the date), and rolled (giant) dice to create number sentences.
Next year I'm hoping to take our different Math Standards and incorporate one activity a month with things like guessing the shape, naming coins, solving and creating number sentences.
I can't wait to see what everyone else does!


Gauss’s Law. Now imagine there are various point charges that are distributed throughout the surface.
The formula will be something like
Which can be written as
=1(total charge enclosed in the surface).
This is the mathematical expression of the law, which is stated as:
“The flux through any enclosed surface is 1 times the total charge enclosed in it.”
Applications Of Gauss’s Law
This is applied to calculate the electric intensity due to different charge configurations.
Intensity Of Field Inside A Hollow Charged Sphere
The charge enclosed in a hollow surface is zero.
So according to the formula
As E=0, therefore the A being multiplied will be zero as well.
So the intensity of the field inside a hollow charged sphere is zero.


Dyscalculia is defined as an impairment of basic arithmetic skills (addition, subtraction, multiplication, division), which cannot solely be explained by a general intelligence deficit nor by inadequate learning environment (ICD-10: Dilling et al., 1993).
In the ICD-11, (developmental) dyscalculia is described as a developmental learning disorder that is characterized by a lack of “skills related to mathematics or arithmetic, such as number sense, memorization of number facts, accurate calculation, fluent calculation, and accurate mathematic reasoning” (World Health Organization, 2020).
Dyscalculia is a Specific Learning Disability now known to affect around 6% of the population. Dyscalculia is highly comorbid with both Dyslexia and ADHD but Dyscalculia is a separate disorder that should be treated accordingly.
Research shows that indicators for developing Dyscalculia can already be detected in 5-6-month-old babies. The researchers discovered that they are attentive towards “numerosities” – in other words, core systems. This is an important discovery not least because these inborn core mechanisms enable fast-track learning. If this core system is not functioning properly, it can be seen long before children enter school.
Doing arithmetic requires a highly specified neuro-cognitive network. The starting point for the development of this network is an early core mechanism. Dyscalculia results when this core mechanism is deficient. Karin Landerl, 2010: Dyscalculia – the Neglected Learning Disability. University of Tuebingen, Germany.
Different people have a range of mathematical abilities – some people have minor problems and react well to being taught in a different way, while other children and adults have more serious problems. Partly these differences seem to stem from the ability to concentrate, so they may be influenced by coexisting conditions – Two Dyscalculia Subtypes With Similar, Low Comorbidity Profiles: A Mixture Model Analysis (2021).
Dyscalculia can include
- Math concepts, numbers, and reasoning.
- Remembering math facts.
- Executing maths procedures.
- Solving mental math.
- Reading clocks to tell time, and time awareness.
- Calendars, schedules and dates, planning and organisation.
- Counting money.
- Identifying patterns.
- Sequences – like phone numbers, addresses, passwords, codes, directions and maps (left and right, up and down, navigating).
- Visual-spatial memory.
For example, mental number line tasks, which require participants to locate a given number on a number line, or the ability to convert auditorily presented numbers into written Arabic symbols (transcoding; Nuerk et al., 2006; Kuhn et al., 2013, 2017).

The Department of Statistics helps students acquire knowledge in respect of conceptual, computational, and mathematical tools for quantifying uncertainty analyzing complex data arising from many applications. Education in the Statistics discipline acquaints students with the role played by probabilistic and statistical ideas and methods in the many fields of science, medicine, technology, and even the humanities. The goal of the Statistics Department is training the students in statistics, both theory and applications, and in probability. Throughout its history, the department has been very active in the development of these subjects to advance other fields in the sciences, medicine, engineering and education. Our college also provides instruction in the theory and application of techniques that have been found to be commonly useful and offer an array of recreational opportunities for our students in the form of social, cultural and sports activities.


Resource Area Dependency Analysis
The principle that underlies this analysis is that if an animal requires a particular amount of a resource, such as a particular tree or area of habitat, then it will extend its home-range to an extent necessary to contain than amount of resource. If the resource is rarer, range outlines will be larger. In this case, there will be a negative relationship between range area and resource content. For strong resource dependence, the relationship tends to become negative exponential (Kenward 1982), but is linear with negative correlation if the logarithm of resource content is plotted against the logarithm of range area. Moreover, the range area at a point where the resource proportion is 1 is an estimate of the minimum area of resource required.


Each year, the Knowles Science Teaching Foundation (KSTF) awards teaching fellowships to exceptional young people committed to teaching physical sciences, biological sciences, or mathematics in U.S. high schools. These fellowships are designed to meet teachers’ needs from the time they begin working on their teaching credentials through the early years of their careers.
KSTF Teaching Fellowships combine extensive financial and professional support. The total award for each fellow is valued at nearly $150,000 over the course of the five-year fellowship. Fellows receive tuition assistance while participating in a teacher credentialing program, monthly stipends, and grants for professional development and teaching materials.
Applicants should have received their most recent content (i.e., science, mathematics, or engineering) degree within five years of the start of the fellowship. Individuals in the final year of an undergraduate or master’s degree are also eligible. Applicants must be enrolled or plan to enroll in a recognized teacher education program that leads to a secondary science or mathematics teaching license. Applicants need not be U.S. citizens but must be able to study and work in the U.S. for the term of the fellowship.
KSTF Teaching Fellowships are awarded based on four selection criteria: science or mathematics content knowledge, commitment to teaching, professional ability, and leadership.


The Apeirographer's Manifesto [PDF]
An artist is one who strives to propel their vision of the world towards the collective consciousness of all humanity. From the neolithic cave paintings at Wadi Sura to the works of classical masters and contemporary artists, an oppressive majority of all art conveys vistas only from the physical and mental realms. This neglect of the mathematical realm arises from the historical scarcity of education and the relative recency of tools fast, flexible, and sophisticated enough for mathematical research, chief among them the programmable computer.
The recognition of this pervasive absence should shock artists of mathematical ability into action, compelling them to fight for their place in history among the pathfinders who labour to reveal novel and timeless glimpses of the infinite and infinitely varied unseen world that is the mathematical realm, anticipating the new era of art history that is upon us.
The Apeirographer is an artist-mathematician, who understands the world through the lens of mathematical realism, perceiving mathematical entities as having existence and reality of their own, independent of the material world—a view shared by Srinivasa Ramanujan, Erdős Pál, and Roger Penrose among other respected academics. Through this paradigm, they recognize mathematics as an exceptional, timeless, and uniquely immutable subject utterly worthy of study and creative exploration.
The focus of apeirography as a movement is the nexus of mathematical research and artistic revelation, the inherent spirit of which calls for the rational rejection of discrimination, hate, and oppression based on ability, creed, ethnicity, gender, legal status, nationality, race, sex, sexual orientation, and any other inherent or externally imposed attribute.
Apeirography is mathematical photography, the art of reifying mathematical entities, properties, and relations in an aesthetic yet faithful manner.
- fine art, aiming to produce aesthetic works;
- documentary art, restricted to mathematically extant subjects;
- representational art, committed to authenticity of representation;
- abstract art, by virtue of its underlying subjects;
- algorithmic art, necessarily;
- digital art or traditional visual art only incidentally.
- not aesthetically complacent,
it demands conformance to the artist's aesthetic vision;
- not a free-form creative process,
it must respect the boundaries of its subject;
- not a result-aimed algorithmic/generative process,
it is revelatory of abstract entities that have always been there;
- not inclusive of all mathematical data representation,
it encompasses only intentional, aesthetically cohesive works of art.

We have had to experiment with different concentrations of baby formula; oddly enough I could not find an online calculator to let me easily figure out how much water and formula to mix to obtain the concentration (calories per ounce) that I wanted.
So I made this -- I hope you find it useful! (Use arrow keys to navigate.)
This formula calculator assumes that your formula follows the same "standard" that I've seen on every formula I've checked; that is, 1 scoop of formula per 2 oz of water to create formula with 20 calories per ounce.
On the formula cans I checked, this "caloric density" was stated in the nutrition area as 100 calories per 5 oz serving. They also stated that each scoop of formula added 0.2 oz to the final volume; so that's what I used in the calculations.
This calculator lets you run the numbers 3 different ways:
1) If you are trying to hit a particular total number of calories with a particular caloric density -- for example if you are making up a pitcher for the day -- the first row should do the trick. Just enter your calorie target and desired concentration in the green cells.
2) As a variation on #1, if you have already figured out that you plan to use a particular number of scoops of formula and know the caloric density you need, try the second version.
2) If, instead, you want to find out what caloric density a particular combination of water and scoops would yield, the third row has you covered.
If you find this useful please drop me a comment! (Also if there are any other calculation variations that you would find extremely helpful, let me know and I'll improve the calculator if I can.)


Nerdle Game: Nerdle, the latest brainteaser, appeals to those who want a numerical version of the viral popular game Wordle. Richard Mann, a British data scientist from London, created the numbers version of the popular puzzle game after his 14-year-old daughter expressed interest in a Wordle for “maths nerds.”
People have been reporting their Nerdle results on Twitter, much as they do with Wordle, since it first appeared last month. Wordle, invented by British software engineer Josh Wardle, was recently purchased by the New York Times for a seven-figure sum.
What exactly is Nerdle?
While the rest of the world was occupied with Wordle puzzles, online gamers now have access to a clone of the popular word game known as ‘Nerdle.’ Nerdle is a numbers game based on the concept of Wordle in which players must arrange a succession of numbers to complete the puzzle.
“For math nerds, there’s a Wordle equivalent.” The goal of the game is to guess the Nerdle in six tries by guessing the “word” that appears on each of the eight tiles.
The colour of the tiles will change after each guess to illustrate how close your guess is to the correct answer. Green indicates that the number is correct and in the proper location. Purple indicates that it is present in the solution but at the incorrect location. It’s not in the word if it’s black.
How to Play Nerdle Game?
If you understand the premise of Wordle, all you have to do now is fill in a few more blocks.
- Nerdle contains eight blocks but the same amount of chances as Wordle, which challenged players to fill a five-character word in six guesses or less.
- The numbers are set in a random order, as shown in the figure above, and must be rearranged for a flawless sequence.
- The blocks glow green if you place the number on the perfect square, purple if the number is in the equation but in the wrong place, and black if the number does not belong, similar to Wordle.
It’s worth mentioning that, like the word game, this numbers game releases a new challenge every 24 hours. Interestingly, this game also allows you to solve past days’ puzzles, which is ideal for individuals who can’t wait for the next task.
What are the Nerdle Game Rules?
To begin with, the game is highly perplexing, and it is a difficult battle. The goal of the game is simple: guess a “eight-character” mathematical equation in six or less tries.
You can choose from the following characters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, +, -, *, /, and =.
“*” is used for multiplication, and “/” is used for division.
The colour of the tiles changes as you arrange the numbers on them. The various colour codes scream at you, indicating whether the equations or numbers you’ve entered are correct or incorrect.
- Nerdle follows BODMAS.
- There are eight “letters”
- A “letter” is one of 0123456789+-*/=
- A “word” must be a calculation that is mathematically correct so must have one “=”
- The number to the right of the “=” is just a number
- Standard order of operations applies, so calculate * and / before + and –
- Order matters. If the answer is 10+50=60, then 50+10=60 isn’t close enough.
- Green – The chosen equation is correct and in its proper location.
- Purple – The selected equation is stored in a location other than where it should be.
- Black– Finally, students receive dark feedback if an input number or symbol does not appear in the mystery equation.
- Grey is the most deadly of all the colours. It tells you how far off the mark you and your chosen equation are.
Nerdle Game Works
Nerdle has added a few wrinkles to the game that set it apart from previous Wordle spinoffs.
The Nerdle Challenge, similar to Wordle, is a daily game. On a certain day, challengers must find out the challenge-equation that applies to all players of the game. If the equation is 12+06/03=14 today, every player who accepts the challenge will get the same answer. A day’s worth of challenges is also restricted to one.
Restart the Game
For all players, Wordle resets at 12 a.m., however the timing is defined by Greenwich Mean Time (GMT). In the official world of Nerdle, the time only follows the norm that makes it protocol, even if the clock struck 12 signalling the start of the next day for you.
Digits, Symbols, and Equation
In Nerdle, the manipulable objects are numbers rather than letters. The symbols for addition (+), subtraction (-), multiplication (*), division (/), and equal to (=) accompany these values. When these things are joined to create various formulae, they produce equations, which may be acceptable but only half correct or entirely correct (the correct answer). Irrational and illogical equations are rejected as guesses in the Nerdle game system. Integers, for example, are acceptable in Nerdle since they are rational numbers, but powers, decimals, and other complex numbers are not.
Nerdle Game Latest Version
Last week, a six-square version of the game dubbed mini Nerdle was released, which, according to the developers, is just as difficult as the original.
Some exciting news. We're delighted to announce the arrival of mini nerdle. Activated in the settings menu, a nerdle with just 6 squares. But not as easy as it sounds! pic.twitter.com/yD8HUMffmU

Wordle has sparked a craze for online puzzles, with new guessing game websites springing up on a regular basis.
For those who prefer numbers over letters, Wordle now has a math-based alternative. Nerdle is the latest game to capitalise on the Wordle popularity, challenging players to solve a whole 8-character computation in only six guesses. You begin with a fully blank grid, similar to Wordle. Green tiles show when you guess a number or symbol in the proper position; purple tiles emerge when the number or symbol exists in the calculation but in a different position; and black tiles appear when the number or symbol does not appear at all.
Nerdle Game applies the tried-and-true formula to numbers. Your job as a player is to calculate the right daily amount using the same numerical digits and arithmetic symbols (plus, minus, divide, multiply, and equals) as a calculator.
You can’t just type in any random characters and hit submit, though, because your equation must make sense. While this may appear to be homework, it may be enjoyable once you get into the swing of things.

When it comes to measuring liquids, knowing the various units of volume and how they relate to each other is essential. One common conversion that often arises is the relationship between quarts and gallons. Understanding how many quarts are in a gallon can be especially useful for cooking, baking, or even simply understanding fluid measurements. In this comprehensive guide, we will explain the conversion between quarts and gallons, offer helpful formulas, and provide practical examples to ensure you have a solid grasp of this volume conversion.
What is a Quart?
A quart is a unit of volume typically used for liquids. It is commonly abbreviated as "qt" and is equal to one-fourth of a gallon. It is further divided into two pints or four cups. The quart is widely used in cooking and baking recipes, as well as in measuring liquids for household purposes.
What is a Gallon?
A gallon is a larger unit of volume primarily used in the United States and abbreviated as "gal." It is commonly used when measuring liquids such as milk, water, or gasoline. A gallon is equivalent to four quarts, eight pints, or sixteen cups. It is important to note that gallons can vary slightly in different countries. For instance, the imperial gallon used in the United Kingdom is larger than the US gallon.
Converting Quarts to Gallons:
To convert quarts to gallons, you can use the following formula:
Number of Gallons = Number of Quarts / 4
For example, if you have 8 quarts, you can find the number of gallons by dividing 8 by 4, which equals 2 gallons. Similarly, if you have 20 quarts, dividing by 4 gives you 5 gallons. This formula provides a straightforward way to convert quarts to gallons.
Converting Gallons to Quarts:
Converting gallons to quarts employs a slightly different formula:
Number of Quarts = Number of Gallons * 4

Solving Graphing Integers Worksheet. The worksheet is an assortment of 4 intriguing pursuits that will enhance your kid's knowledge and abilities. The worksheets are offered in developmentally appropriate versions for kids of different ages. Adding and subtracting integers worksheets in many ranges including a number of choices for parentheses use.
You can begin with the uppercase cursives and after that move forward with the lowercase cursives. Handwriting for kids will also be rather simple to develop in such a fashion. If you're an adult and wish to increase your handwriting, it can be accomplished. As a result, in the event that you really wish to enhance handwriting of your kid, hurry to explore the advantages of an intelligent learning tool now!
Consider how you wish to compose your private faith statement. Sometimes letters have to be adjusted to fit in a particular space. When a letter does not have any verticals like a capital A or V, the very first diagonal stroke is regarded as the stem. The connected and slanted letters will be quite simple to form once the many shapes re learnt well. Even something as easy as guessing the beginning letter of long words can assist your child improve his phonics abilities. Solving Graphing Integers Worksheet.
There isn't anything like a superb story, and nothing like being the person who started a renowned urban legend. Deciding upon the ideal approach route Cursive writing is basically joined-up handwriting. Practice reading by yourself as often as possible.
Research urban legends to obtain a concept of what's out there prior to making a new one. You are still not sure the radicals have the proper idea. Naturally, you won't use the majority of your ideas. If you've got an idea for a tool please inform us. That means you can begin right where you are no matter how little you might feel you've got to give. You are also quite suspicious of any revolutionary shift. In earlier times you've stated that the move of independence may be too early.
Each lesson in handwriting should start on a fresh new page, so the little one becomes enough room to practice. Every handwriting lesson should begin with the alphabets. Handwriting learning is just one of the most important learning needs of a kid. Learning how to read isn't just challenging, but fun too.
The use of grids The use of grids is vital in earning your child learn to Improve handwriting. Also, bear in mind that maybe your very first try at brainstorming may not bring anything relevant, but don't stop trying. Once you are able to work, you might be surprised how much you get done. Take into consideration how you feel about yourself. Getting able to modify the tracking helps fit more letters in a little space or spread out letters if they're too tight. Perhaps you must enlist the aid of another man to encourage or help you keep focused.
Solving Graphing Integers Worksheet. Try to remember, you always have to care for your child with amazing care, compassion and affection to be able to help him learn. You may also ask your kid's teacher for extra worksheets. Your son or daughter is not going to just learn a different sort of font but in addition learn how to write elegantly because cursive writing is quite beautiful to check out. As a result, if a kid is already suffering from ADHD his handwriting will definitely be affected. Accordingly, to be able to accomplish this, if children are taught to form different shapes in a suitable fashion, it is going to enable them to compose the letters in a really smooth and easy method. Although it can be cute every time a youngster says he runned on the playground, students want to understand how to use past tense so as to speak and write correctly. Let say, you would like to boost your son's or daughter's handwriting, it is but obvious that you want to give your son or daughter plenty of practice, as they say, practice makes perfect.
Without phonics skills, it's almost impossible, especially for kids, to learn how to read new words. Techniques to Handle Attention Issues It is extremely essential that should you discover your kid is inattentive to his learning especially when it has to do with reading and writing issues you must begin working on various ways and to improve it. Use a student's name in every sentence so there's a single sentence for each kid. Because he or she learns at his own rate, there is some variability in the age when a child is ready to learn to read. Teaching your kid to form the alphabets is quite a complicated practice.


An operator is used to perform some sort of operation on variables and values.
a = 4 b = 7 c = a + b print(c)
Python has the following type of operators
- Arithmetic operators
- Assignment operators
- Comparison operators
- Logical Operators
- Membership Operators
- Identity Operators
- Bitwise Operators
Arithmetic operators –
Arithmetic operators are used to performing basic arithmetic or mathematical operations. They include –
+, -, *, /, %, **, //
+ operator is used to perform addition, ‘-‘ is used to perform subtraction on two numbers, * is used for multiplication.
a = 6 b = 4 print(a + b) print(a - b) print(a * b)
/ and % operators are used to perform division. The only difference between them is ‘/ ‘ returns the quotient whereas ‘%’ returns the remainder.
a = 8 b = 2 print(a / b) print(a % b)
** operator is used for calculating the exponential of a number.
a = 10 b = 2 print(a ** b)
// operator is used to calculate floor division. That is it rounds off the result to its nearest whole number.
a = 5 b = 2 print(a // b)
These operators are used to assign values to variables.
‘=’ is used to assign a value to a variable.
a = 12 print(a)
+= is the increment assignment operator. It adds a value to the existing value of a variable.
a = 4 a += 2 print(a)
In the above example
a += 2
is equivalent to
a = a + 2
In the exact same way, we have ‘-=’, ‘*=’, ‘/=’, ‘%=’ and ‘**=’.
|Expression||Is equivalent to|
|a -= 2||a = a – 2|
|a *= 2||a = a * 2|
|a /= 2||a = a / 2|
|a %= 2||a = a % 2|
|a **= 2||a = a ** 2|
Comparison operators are used to compare two values. Any expression having a comparison operator returns a boolean value – true or false. There are several comparison operators in python which are ==, !=, >, <, >=, and <=.
a = 4 b = 4 print(a == b)
In the same way-
|!=||is not equal||a != b|
|>||is greater than||a > b|
|<||is lesser than||a < b|
|>=||is greater than or equal to||a >= b|
|<=||is lesser than or equal to||a <= b|
The logical operators combine multiple conditional statements
and – It returns True if all the conditions are true. If any one of the conditions is False, the overall statement returns False.
x = 1 y = 2 print(x < 4 and y < 4)
or- It returns True if any one of the conditions is true. If all the conditions are False, the overall statement returns False.
x = 1 y = 6 print(x < 4 or y < 4)
not- It reverses the result of any conditional statement.
x = 10 print(not(x < 20))
There are some other type of operators as well, but they can only be understood if we know the concepts of conditional statements, collections types etc.
So as of now this should be enough, after some later tutorials, the remaining operators would be discussed.

The Department of Mathematics is planning to propose changes to the current precalculus and calculus courses at its upcoming curriculum committee meeting, which includes merging courses into two different integrated courses.
The proposed changes are planned to help students with their schedules and workloads and is expected to be more effective than the current courses being taught.
The changes were discussed during a self-study that every department is required to conduct every 10 years, according to Tamara Lakins, chair of the math department.
“One of the driving forces for our self-study was that we really wanted to look at the ways to improve student success rates in our introductory mathematics courses,” Lakins said. “Really, we wanted to think about how we can help students.”
These new classes would make additional changes to the two calculus tracks, the Social and Life Sciences track and the second track made up of Calc I, II, III, that students can take after taking the mathematics placement exam which all students are required to take before matriculation.
“We were concerned there that students were having to decide really early in their careers which track to take, and since students often change their mind when they’re thinking about what they want to major and minor in,” Lakins said. “Students who took the social life science calculus might have had to do some extra work to move to the other sequence. That’s not going to happen now.”
In order for all changes to occur, the proposal first has to be sent to the curriculum committee, according to Jared McHale, ’20, one of the five students on the curriculum committee.
“All student representatives are voting members,” McHale said. “(The proposal) has to be voted on and approved by the committee first, but the faculty still has the option of turning it down.”
McHale agreed the changes will be beneficial to students if approved and put into place, especially for those who are not math majors and minors but need the courses for other requirements.
“I do think it’s helpful for students who aren’t majors and minors that the math department is breaking up the sequences,” McHale said. “It also makes scheduling easier, because some will be offered three days instead of the four day class (which is offered now).”
Registrar and Associate Dean of Academics Ian Binnington, is another member of the curriculum committee. He works to decide whether to implement the proposed changes.
“This committee is made up of the five students elected by ASG, and the faculty, plus the faculty chair, professor Hellwarth in the English department,” Binnington said. “(Changing the curriculum) is a routine event that happens multiple times every year. Obviously, the math department is a significant department to be changing (since it is required for so many other subjects), but each new bullet presented is different from the one proceeding it from the year before.”
Binnington said the decision to approve the curriculum changes depends on the case made by the faculty in the department and if there are any issues they might have forgotten or not considered.
“We rely on the expertise of the faculty in the field and make sure we understand how the transition will go also,” Binnington said. “Then there are two faculty meetings, one where we discuss, and then one where we vote.”
Binnington helps incoming students decide which path to take and said these changes in the math department will add an additional benefit for students as well.
“It will make it a lot simpler for incoming students to understand what to do,” Binnington said. “I’m very excited for these changes, they will benefit students (a lot).”
If the changes are approved, the current courses Math 157/158 and Math 159 would be eliminated and replaced with Math 140 and 141, which would be calculus I with precalculus, part 1 (140) and part 2 (141).
The current four-day-a-week math sequence which includes Math 160, 170 and 210 would also be eliminated to be replaced by four new courses: Math 151, or calculus I; Math 152, or calculus II; Math 211, or vector calculus and several variable integration; and Math 270, or optimization and approximation, that would meet three days a week.
With the new courses being offered, some of the old courses will be eliminated at the end of the spring 2019 semester depending on if the proposal goes through. These courses include; Calculus I for Social/Life Sciences (Math 157), Precalculus (Math 159), Calculus I (Math 160) and Calculus II (Math 170).
For some courses, the transition period will be longer due to students currently enrolled in Math 157, who would need Math 158 in the fall, along with those who would still need Math 210.
“For example, if a student is a biology major and they’re in 157 right now, and they need 158 then we will teach 158 next fall, even though it’s one of the old courses, so the student can finish the math for their degree,” Lakins said. “There will also be one more fall offering of Math 210, that’s calc III. That will be for students who are currently in calc II, and if they succeed we want to give them a calc III. We don’t want to just take the course away from them.”
Lakins said current students who are successful in the courses they are taking this semester will have an easy time transitioning to the new system, but those who do not receive a C grade or higher may be forced to take a student initiated withdrawal in one class, because they will not be able to retake some of the current courses after this semester.
“(Students) will hopefully be able to move on to the other, new class and do much better in that class,” Lakins said. “But one low grade doesn’t prevent you from graduating, even though it might look like a big deal at the time.”
Lakins and the rest of the department want to help students and said students could be moved into the new courses, if necessary.
Depending on the needs of students, there will be a class for a student at each level that will be recommended for the fall 2019 semester or after the changes are made. Students in need of 158 and 210 in the fall are recommended to take those courses then, and those in need of calculus I or II will be able to move into the new courses in the fall semester.
Lakins said the math department faculty want to make the transition easy for students and hope the new system will make taking math courses less stressful for them. Lakins said students with questions are welcome to contact her.
“We are making all these changes because we want our students to succeed,” Lakins said. “We really believe that making these changes will help us to achieve that goal.”


I’m going to skip the part where I explain why I haven’t been posting.
Here are some thoughts that have entered my skull this week:
- At a staff meeting, they kept referring to Administration as “Admin”. Naturally, this led me to the greatest idea ever: a Mad Men spinoff called Madmin. If you steal this idea, I will cut you.
- According to the teacher I work with, a male faculty member said that I “have the cutest dimple in my chin”. Pretty sure that’s just a zit. Sorry.
- I generated Pascal’s Triangle with a 5 year old. The kid was able to see the pattern in the diagonals. Genius. Although he struggled with addition of two numbers greater than 5.
- Best student-generated math problem ever: “Snoop Dog was running at a rate of 6 miles per hour to get to his ’64 Impala, which is 30 miles away. How long will it take him to get to the garage?”
- So there is a street that runs perpendicular (that’s geometry) to my street, but it once it hits my street, it stops, forcing cars to turn left or right. However, I just realized if cars were to keep going straight, they would go straight into my driveway. I literally have to look 3 ways before I can back-out. I’m not mad, it’s just weird. Anybody else have this same predicament?
- There is a girl eating a green banana in my classroom. Do I tell her to wait?
- Here are the notes I took during an observation of a geometry class:
- The bell rang so I need to stop.

Finally An Effective Method Of Counting Blackjack Cards Without Being A Genius
This card counting technique was brought to the big screen in the excellent film Las Vegas 21, in which brilliant students from the prestigious American university Massachusetts Institute of Technology, more commonly known as MIT, fly to Las Vegas in an attempt to ” pocketing the jackpot at the blackjack tables. In this film, the students and their blackjack teacher are presented as math prodigies.
Obviously, before you start blindly, you have to go through the “theory” box. You need to learn how the strategy of counting cards during games to determine the house edge works, to be able to apply it and to know how to count cards in blackjack. If you have two hours ahead of you, we recommend that you watch the movie Las Vegas 21 which shows how the MIT group of players teach their members to count cards.
The strategy, as you will see in our article, is quite simple, but it takes a lot of practice, so you have to play and play again for the mechanic to be in your mind.
On the surface, the method is very simple. This involves counting the cards played during the game to determine the cards remaining in the shoe. To do this, it suffices to assign a number of points to a card or a group of cards, and to subtract or add as the cards come out of the shoe. The player must therefore count and mentally count the cards coming out of the shoe, while remaining focused on his game. Based on his calculations, the player will be able to determine when he can increase his stake at will.
Now let’s take a closer look at the most commonly used blackjack card counting technique.
The technique of counting cards with variants that we will also present to you, but here is the most practiced of them. Again, it’s not more complicated, you just have to understand it and apply: we’re sure you’ll love the concept.
So far, nothing very complicated. For example, if in a hand I have a 7 and a 3 then my total will be 1 point. The player must therefore bet when his blackjack card count result is the highest. Indeed, small cards are worth 1 point and large cards – 1, if the total of his card count is high, it means that a lot of small cards are already out, and therefore that the player will have more chance to see appear. big cards in those remaining in the shoe.

Knapsack? What sack?
The knapsack problem is a problem in combinatorial optimization: Given a set of items, each with a weight and a value, determine the number of each item to include in a collection so that the total weight is less than or equal to a given limit and the total value is as large as possible. It derives its name from the problem faced by someone who is constrained by a fixed-size knapsack and must fill it with the most valuable items. The problem often arises in resource allocation where the decision makers have to choose from a set of non-divisible projects or tasks under a fixed budget or time constraint, respectively.

It is still warm outside but in another couple of months temperatures will start to drop. Now is the time to consider purchasing a pool heater if you don’t already own one.
A common question that consumers ask us when shopping for swimming pool heat pumps is: How big does my heat pump need to be? You should have a trained swimming pool professional size your swimming pool heat pump, as its size will depend on many factors. There are, however, general formulas we provide to our customers to approximate heat pump size. We explain how to use these formulas in this article.
Heat pumps are sized according to required BTU (British Thermal Unit) per hour of the swimming pool. Consumer often make the mistake of purchasing under-sized units units with insufficient BTU output per hour. Under-sized units must run longer in order to heat swimming pools. These longer run times translate to decreased efficiency and higher operating costs. Use the following instructions to approximate the BTUs per hour your heat pump will require.
- Determine your desired water temperature in °F.
- Determine the average air temperature of the coldest month during which you plan to use your swimming pool in °F.
- Subtract the average air temperature from your desired water temperature to calculate the required temperature rise.
- Calculate the surface area of your swimming pool in ft2:
- Circular pools: radius x radius x 3.14
- Kidney-shaped pools: length x width x 0.75
- Oval-shaped pools: (0.50 x length) x (0.50 width) x 3.14
- Rectangular pools: length x width
- Calculate the required BTU output per hour: surface area x temperature rise x 12

If you're studying or working in the science or financial sectors then the chances are you need a powerful calculator. But why carry a bulky device around with you when you can simply install one on your Android mobile device?
Android RPN Calculator is a handy Reverse Polish notation calculator designed to solve all manner of equations. The app, which comes with menu bar functionality, consists of a large number pad display with a series of functions above it. The interface is fairly attractive and generally easy to get around thanks to the large buttons and well-labeled mathematical function keys.
However, Android RPN Calculator's settings menu isn't quite so well-designed. Because the menu highlights are in white and the text is in white, it's difficult to make out what all of the options are , and you'll find yurself having to squint at the screen a fair bit. Among the settings you can change are Rounding, Number Types, and Decimal placings.
Unfortunately there's no help facility, so if you're not a proficient mathematician you almost certainly won't get much benefit from Android RPN Calculator. Even if you are, you'll probably get frustrated by the 'unfinished' feel of the app. The app is pretty buggy, many of the buttons return 'not implemented' errors, and it's only currently available for HVGA-P displays.
Nevertheless, if you need to perform complex equations on a regular basis, Android RPN Calculator represents an easier way than carrying around a calculator with you.

It looked nice, reminding somewhat of a simple HP calculator like HP10C, but have only got the non shifted keys working.
Pros: stack larger than the four x,y,z,t
Cons: Not all keys working, only the white unshifted not the orange shifted
