Hey GMAT Aspirants!
One thing that I realized when I was once in your shoes as a student is that there is very minimal free content over the internet for GMAT, and while there are a lot of paid courses and materials that you can find, your heart never knows how to pick the right one.
Well, I might have just solved your first problem, I have compiled a list of free websites and youtube videos that you will need to cover not only for the basics of algebra and its topics but also for GMAT-level preparation.
I- Simplifying Rules
Just as before driving a car you understand the basics of a clutch, accelerator, and break, similarly, before you start attempting Algebra questions, you need to be familiar with topics such as:
-Properties of Equality
The below link covers the basic rules you apply while solving any question of Algebra, it simplifies all the rules may it be addition, multiplication, with one /two or even three variables, making you quicker while solving any question.
When you go through the above links you see one word that comes up a lot i.e. Polynomials, what are they? and how we solve them is what you’ll find below
Explore the connection between polynomials and integers, by adding, subtracting, and multiplying polynomials.
Get equipped with a variety of key strategies for breaking down higher-degree polynomials. From taking out common factors to using special products.
After addition, subtraction, and multiplication of polynomials, it’s time to divide them! This will prove to be a little bit more sophisticated.
II- Linear Equations
Let’s come have a look at the below equations,
x + y = 21
x – 26 = 567
What do they have in common?
Both equations are examples of linear equations
Let’s understand what that is through the video below
The above video gave you an introduction to what linear equations are, now let’s dive into a deeper knowledge of the topic
Now let’s move past one power and get introduced to the two power equations.
III- Quadratic Equations
Quadratic equations are second-degree polynomial equations, which means the highest power of the variable (usually represented by “x”) in the equation is 2.
The general form of a quadratic equation is:
ax2 + bx + c = 0
where “a,” “b,” and “c” are constants, and “x” is the variable. The constant “a” cannot be equal to 0 because that would turn the equation into a linear equation.
Let’s go deeper into Quadratic Equations
You will here learn how to solve quadratic equations, which include terms where the variable is raised to the second power.
Solving quadratics by factoring
You will learn how to use factorization methods in order to bring other equations to a factored form and solve them.
Quadratic: Multiplying & Factoring
You’ll learn how to multiply algebraic equations by numbers and by each other, you’ll also understand the factorization of algebraic equations.
Here are some ‘quadratic equations’ questions for you to practice
Inequalities refer to mathematical statements that express a relationship between two expressions using greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), or not equal to (≠) symbols.

8.16 Suppose we implement partial path compression on find(i) by making every other node on the path from i to the root link to its grandparent (where this makes sense).
This is known as path halving.
a. Write a procedure to do this.
b. Prove that if path halving is performed on the finds and either union-by-height
or union-by-size is used, the worst-case running time is O(Mα(M,N)). - Get solution

Dimensional Weight (DIM)
Dimensional (DIM) weight refers to how dense a package is, or the amount of space a package occupies relative to its actual weight. The classic example of a low-weight, high-volume shipment is a box of ping-pong balls — they occupy a disproportionate amount of space relative to their weight. Parcel carriers use DIM weight to ensure fair payment for shipping parcels that are relatively light for their size.
The actual billable weight of a parcel becomes the greater of the dimensional weight or the actual weight. The dimensional weight is calculated by dividing the cubic size of a parcel in inches (the product of multiplying your package’s length x width x height) by a factor provided by the parcel carrier (subject to change).


15 Fun Ways to Practice Math
Learning basic math -- addition, subtraction and multiplication -- for adults is no different than learning basic math for children. The only real difference is that an adult's other cognitive abilities, including language, are usually better developed than those of a child at the same stage of math learning.
So it's usually easier to explain the concepts to an adult than it is to a child. Start getting a grip on the basic concepts of addition and subtraction by using five of an identical item. These could be five oranges, five grapes, five tennis balls, five bricks Line up all five objects and count them. Now remove one object from the lineup and place it to the side. This is the same as subtracting one from your original number, which was five. What is five minus one? Count the remaining objects to find out: four.
Return the object you removed to the lineup. You had four objects, now you have added one, and as you can see, there are now five objects again. So four plus one equals five -- the evidence is right in front of you. Reset your lineup of five objects, then repeat the exercise while removing two, three, four and, finally, all five of the objects.
Once you've removed an object and calculated the result, add it back in and recalculate the result. Expand your grasp of the subject, now that you understand the basic principle of it, by memorizing addition and subtraction tables.
See the Resources section for links. But this method is great because they all fit nicely into the card box, making for easy and portable storage. Make a recipe. Put those skills to the test by making no-bake cookies or even slime. For more of a challenge, have students double, triple or even quadruple the recipe. Borrow or buy an adding machine. Do you remember the simple joy you had when playing around with an adding machine? If not, go to your nearest thrift store to find one!
Students will love being able to punch in numbers and have the math problems come out on real paper. Download Sudoku and Kakuro puzzles. Sudoku is definitely a good way to practice math, and you can find puzzles, books and samples all over the place.
Not as many people know about Kakuro puzzles though. They are similar to Sudoku in that they come in a grid, but the rules are different. Download math apps. This is another area where you can find oodles of options. With most schools having access to tablets, this is a great way to make practice fun for your students. Look for math games best suited for your age group most apps have age recommendations.

The Fourier Transform
This post is way overdue, so let’s get right to it.
Say we have some function, g(x); thus, this function maps x to some value g(x). You can think of the variable x to represent time. Now we want to be able to approximate g(x) to its sum of trigonometric oscillations i.e.; some sine waves of a certain frequency, ω. There will obviously be some frequencies that fit well, and some that won’t. Therefore we need some value ĝ(ω) that tells us just how much of a given oscillation with frequency ω is present in the approximation for g(x)
Now, let me illustrate this point further with a graph I made, taking into account the blue oscillation, which we’ll call g(x)
As you can see, it’s defined as g(x) = sin(x) + 0.13sin(3x).
The red oscillation and yellow oscillations can be considered approximations to g(x). Let’s take a look at the red one, which is just sin(x): it’s obviously the closest approximation of the two to the original function, and will therefore have a bigger impact on the results. It has a frequency, ω = 1, so let’s say that
ĝ(1) = 1
Now taking a look at the other, less impactful approximation of the yellow oscillation, 0.13sin(3x), we see that it has a frequency ω = 3. Thus,
ĝ(3) = 0.13
Since there are no other functions apparent in the graph (and thus, no more frequencies, ω, used to approximate g(x)) we can write for these sort of non-present frequencies,
ĝ(ω) = 0
If we knew all ĝ(ω) values for all possible frequencies, ω, we could PERFECTLY approximate g(x). This is what the continuous Fourier Transform does: it takes some function, g(x), and returns some other function, ĝ(ω) = Ƒ(g), where Ƒ(g) is the Fourier Transform of the function g(x). This describes how much of a given frequency is present in g(x); it’s just another way of representing the information of g(x), but in a different domain.
This is generally easier to solve than with the function g(x) because sometimes g(x) can be really really complicated — the Fourier Transform has a lot of interesting mathematical properties that make computation much simpler. It can change convolutions to multiplication, and it can turn unsolvable PDEs into ODEs (which we generally have techniques to solve) as well as turn ugly, computation-intensive ODEs into linear equations which are soooo much easier.
I might make a post later on a less applied way of describing the Fourier Transform, but I think relating it to applied mathematics is the easiest way to explain it.

The application field of PLASIMO ranges from non-flowing plasmas, to subsonic and supersonic flowing plasmas. This implies that the calculation procedure for the flow field should handle incompressible and compressible flows, from Mach number M = 0 to M > 1. PLASIMO uses a modified version of the well-known Semi-Implicit Method for Pressure-Linked Equations (SIMPLE) . The co-located grid method developed by Rhie and Chow  is used, together with the momentum-interpolation scheme at the control volume faces of Majumdar . To describe incompressible as well as compressible flows the formulation of the pressure-correction equation according to Karki and Parankar  is used.
Capabilities of PLASIMO's flow solver and the correctness of its implementation are presented by benchmarking against well-established analytical and numerical test cases.
The driven cavity problem is a classical benchmark test problem and has long been used as a test case for Navier-Stokes solvers thanks to its simple geometry and boundary conditions.
This test models flow in a square box which is driven by the motion of the lid of the box. The two-dimensional square cavity has no slip boundary conditions on all walls, the flow being driven by the top wall sliding across the cavity whilst the side and bottom walls are static.
The figure below shows a comparison between PLASIMO's results and the results obtained by  for Reynolds number of 1000.
|PLASIMO||Ghia et al. [ 5 ]|
Laminar swirling flow is produced by a rotating bottom of a closed cylinder. The fluid, which completely fills the cylinder, is incompressible, of uniform density and a constant kinematic viscosity [ 6 ].
The figure below shows a comparison between PLASIMO and Ref. [ 6 ] of the azimuthal vorticity.

This mathematical rule specifies the correct order of operations to be used when answering a mathematical number sentence question with multiple operations.
The first step in BODMAS Rule is to do anything in brackets, followed by orders (such as square root or indices). Division and multiplication are on the same level, which means they have equal priority and should be done from left to right, rather than all-division first, then all multiplication.
Similarly, addition and subtraction are on the same level and should be performed from left to right.
In this article, we are going to discuss the importance of the BODMAS rule as well as the meaning of the BIDMAS rule.
History of BODMAS
Achilles Reselfelt is a mathematician and the creator of BODMAS. It’s a mnemonic that helps us remember how to evaluate mathematical operators in a mathematical statement that includes more than one mathematical operation.
What is the BODMAS Rule?
We use the acronym BODMAS to help children remember the order of mathematical operations – the correct order in which to solve math problems.
B stands for Brackets, O stands for Orders (powers/indices or roots), D stands for Division, M stands for Multiplication, A stands for Addition, S stands for Subtraction are the abbreviations for Bodmas.
According to the Bodmas rule, mathematical expressions with multiple operators must be solved from left to right in this order. Division and multiplication are interchangeable and are determined by which comes first in the expression, as are addition and subtraction.
The Bodmas rule as a mnemonic (similar to how Richard Of York Gave Battle In Vain is used to remember the colours red, orange, yellow, green, blue, indigo and violet).
What is the BIDMAS Rule?
To help remember the order of operations, the BIDMAS rule is an alternative acronym to BODMAS. The only difference is that an I is used instead of an O. The underlying meaning is the same. Today, the term “BIDMAS” is more commonly used in primary schools all over the world.
BIDMAS is an acronym that stands for Brackets, Indices, Division/Multiplication, and Addition/Subtraction.
Operation in Mathematics
What you do with the numbers is referred to as “mathematical operations.” The four main operations are as follows:
- (+) addition
- (-) Subtraction
- (x) multiplication
- (/) division
What Does the Term Order of Operations Mean?
This is the order in which certain operations must be completed, beginning with brackets and ending with addition and subtraction.
Division and multiplication must be represented alongside each other because they are equally important (and must be completed from left to right, whichever appears first) – the same is true for addition and subtraction.
Why is the BODMAS Rule Important?
If you had to quickly determine which math operation to perform first in the following expression, 3 + 6 – 4 x 5, you might be perplexed as to whether to proceed with addition, subtraction, or multiplication. To alleviate this confusion, the BODMAS rule was developed to assist students in remembering the correct order in which calculations should be performed.
It is regarded as one of the most important mathematical principles, underpinning many of our mathematical conventions. All students should learn the BODMAS rule before beginning algebra in school. It will make mastering more difficult math concepts much easier.
Learn Maths From Cuemath Website
It’s important for students to learn Math because it teaches them what numbers are and how they relate to real-life situations. It enables them to become self-directed learners and equips them with the knowledge to pursue opportunities in a variety of fields.
When dealing with topics such as BODMAS, students may feel uneasy about grasping the concept because the easier it appears, the trickier it is to arrive at the correct answer if not thoroughly understood. As a result, students might be dissatisfied.
Do you find the BODMAS Rule very difficult to understand? If yes, you can visit Cuemath website to learn maths and understand the concept in a fun and easy way.


Poker odds calculator app is a reliable player assistant that facilitates the game process and calculates the probability of a particular combination; moreover, it is a free download tool. If a player uses it wisely, it will give him a bunch of information about the players’ cards, and it will help the gamer to win. One can find an appropriate Poker hand odds calculator online and use it even when he masters the card game. No one will prohibit a player from applying this useful tool, when the Poker is played for real money.
The player can calculate the chances of winning the distribution without using additional software. Meanwhile, is not always convenient applying quick odds formulas Firstly, there is a chance of error. Secondly, “fast formulas” give a very approximate result in percent. In addition, manually calculating odds is tedious and boring. Why spend time on this when one can load all the data into the program, click on the button and get the result?
Poker odds calculator usage
Almost all Poker odds calculator software uses the same principles: mostly design is different, but all of these tools can calculate the player’s outs. The table is marked for the maximum number of players. It also provides for the introduction of cards on each street post-flop to update information on probability.
The first thing to note in the answer is the position. It plays an important role in building tactics during the game, especially for beginners. The closer the player’s position to the button, the more information about the chances of opponents he has.
On the first round of betting, the player marks his place at the table and the cards that have arrived. While everyone makes bets, he is counting. For instance, he gets 9 and a King, and Texas Hold’em Poker odds calculator immediately calculates to win at the current stage of the game.
Opening a Flop seriously changes the chances of winning. During the draw, some players will pass; this is also noted by the poker calculator. In addition to the immediate chance of winning the hand (expressed as a percentage), the tool calculates the chances of making this or that combination, which in itself makes the game even easier. The calculator allows a gamer to track the opponent’s chances to collect the highest combination, and if they are insignificant, he can safely make larger bets.
The best Poker calculators
Here are the tools that are called the best assistants for online Poker players:
- Pro Poker Tools — cool Poker odds calculator;
- Pokerlistings Hold’em Odds calculator;
- Poker Stove Odds.
No one should not forget that Poker odds calculator performs exclusively mathematical calculation according to a pre-prepared algorithm that is based on the statistics of the loss of card combinations. It is not able to foresee such behavior of players as bluffing and other things. Therefore, many other factors should be taken into account.


Betting tips help you predict the right outcome of the soccer match in order to place a bet. The most popular tips are the statistical predictions. Poisson method is the oldest prediction method and the one best known in literature.
This article summarizes the Poisson method for soccer prediction, its advantages and disadvantages.
Statistical soccer prediction methods mostly started appearing from the early 90s, but the first (and so far the most famous) method was published by Moroney in 1956. According to this method, soccer match scores can be successfully modeled as random observations drawn from the Poisson probability distribution. Let’s assume that x and y represent the number of goals scored by home and away teams respectively. Thus, according to the Poisson method x and y are random variables, each one coming from its own independent Poisson distribution. The Poisson distribution function differs for each team.
The function has its own parameters (mean in the Poisson case), defining the expected number of goals scored by the opponents. Once the parameters of the distribution function are correctly estimated, the match outcome can be successfully predicted. It is clear that when estimated empirically, the parameters of any function include some error due to the limited number of observations. Thus, the predictions of soccer match are usually incorrect. This estimation error defines the confidence intervals assigned to the predicted number of goals.
The main advantage of the Poisson model is its ability to predict the expected number of goals. It holds for almost all soccer tournaments. Additionally, the estimation of mean for the Poisson distribution is usually based on all the historic matches played during a specific tournament, thus making the estimation reliable.
However, this method has many disadvantages. It predicts scores for each team independently, not taking into account the opponent’s team’ strength; It doesn’t distinguish between the attack and defense skills of the teams and doesn’t consider the time-dependent changes of these skills; In addition, it doesn’t refer to the influence of home ground advantage on the final score.
All those drawbacks resulted in further developments based on this method. The newer methods distinguish between attack and defense strengths of the teams, consider the strength of the opponent team and take into account home ground advantage. We will discuss these developments in our next articles discussing the evolution of statistical soccer predictions.


Just how can Math Abilities Help Me At Holdem poker?
The overall game of online poker involves much more than just outplaying your opponents or continually striving to raise the level of your skills, all the while maintaining a online poker face. Whether you like it or not, poker also requires a certain level of math skills before you decide to increase, fold, call or bet. There are numerous situations in a online game when you will need to activate your math skills and then help to make an informed decision since doing this can greatly increase your chance of successful.
Whilst actively playing your online game, you will need to convert likelihood, which is measured in percentage, into odds. In order to do that, you will have to subtract the probability from 100 and then divide that result again with the probability. For example, if the probability is 20%, then you will have to subtract 20 from 100, which is 80 and then divide 80 by 20, which comes to 4. Which means that the odds are 4 to 1 “against�. This means that the chances of success are 1 in every 5 attempts since you will first need to add 4 with 1, which equals to 5. In other words, this means that out of every 5 times that you perform, you have 1 chance of succeeding. This calculation will help you to decide in advance as to whether it is worth actively playing ahead, thus helping you save some serious cash or even earning a large amount if you find that the chance of winning is much higher.
Another example where math will be required is that if the value of the pot is $100 and if you need to bet a minimum of $10, then based on the above point you will need to multiply $10 with 5 [odds], which is equal to $50. Which means that the pot is paying you more than $50 and thus you are able to take the risk since the quantity that can be won provides you with a positive expectation. Nevertheless, if the pot only has $40, then you could face an adverse expectancy of $10 in the event you decide to make the wager. This particular calculations will help you to compare your risks with the rewards and can allow you to raise, fold, call or bet.
Your numerical calculation won’t need to be made in the beginning of every game but based on the money in the pot and the bets that have been placed, you will also need to do some re-calculations when the ‘Turn’ and ‘River’ credit cards are dealt. Additionally, you will need to base your math calculations on how your opponents place their own bets since you might suddenly find a positive expectation turning into a negative expectation or vice versa as the game advances.
In addition to math skills, additionally, you will need to master other skills for example keeping a tight reign in your emotions, intent focus on your own online game as well as those of your opponents and the ability to oversee your own money. Although math abilities are a fundamental element of good poker strategy, a mix of all the above skills is eventually what will set a person apart from your opponents.
There are lots of players who’ve a phobia concerning math and hence concentrate on only using their additional abilities while ignoring the actual numerical aspect of this online game. This can prove counterproductive. Math skills are not very hard to master and once you start using them, you will realize that your likelihood of winning multiply extremely fast.


|Abstract: ||A method of increasing an efficiency at which a plurality of threshold
gates arranged as neuromorphic hardware is able to perform a linear
algebraic calculation having a dominant size of N. The
computer-implemented method includes using the plurality of threshold
gates to perform the linear algebraic calculation in a manner that is
simultaneously efficient and at a near constant depth. "Efficient" is
defined as a calculation algorithm that uses fewer of the plurality of
threshold gates than a naive algorithm. The naive algorithm is a
straightforward algorithm for solving the linear algebraic calculation.
"Constant depth" is defined as an algorithm that has an execution time
that is independent of a size of an input to the linear algebraic
calculation. The near constant depth comprises a computing depth equal to
or between O(log(log(N)) and the constant depth.

I'm exhausted, my feet hurt, and my throat is sore, but the first day of school went really well! I am teaching my own daughter for the first time in my third period Geometry class, which is really strange (but good). We had to cover the classroom rules and policies (a first day of school must at my school), but then we really got to have fun.
In my two Geometry classes, we played 31derful, found at Sarah's blog. I love this game for my geometry classes because it gets them thinking outside of the box, and I love hearing all the mathematical discussion that went on in those classes. The groups that finished got stickers. I don't know what it is about stickers, but my students love them!
In my three Algebra 2 classes, we did some error analysis. I found a worksheet at Teachers Pay Teachers a long time ago that had algebraic expressions and equations that were simplified incorrectly. The goal of this activity was to identify the error (using words) and to correct the expression or equation. The students worked great on this activity, but I was very surprised that most of them wanted to work on their own. Which, by the way, is not a problem at all. They were all engaged in the activity, but I wonder if they could have gotten more out of it with some discussion among themselves.
In my one Statistics class, I used a couple of activities from The Practice of Statistics, 5th edition. I talked through the article at the beginning of the book, "What Is Statistics?" We then did the hiring discrimination simulation to lead us more into thinking about the big picture of stats. Both of these activities took much less time than I had anticipated. So, we went ahead and started with the first lesson, which I had initially prepared for tomorrow. Yay for both planning ahead and for making my copies ahead of time!


“The goal of Common Core is to use one sheet of paper for every problem,” Bargatze jokes. He observes that this new math requires people to “keep breaking the problem down.”
“You put the problem at the top, and it just keeps going,” Bargatze says. “And then what’s funnier is you see old math in the middle of it. As you break it down, old math gets in there and you’re like, ‘Oh, just do that at the top.’ I don’t even know what we’re doing.”
Bargatze is by no means alone in his frustration. Since many schools went largely remote during the COVID-19 pandemic, countless parents, me included, are becoming burnt out as we find ourselves thrust into the role of substitute math teacher.
Why does this so-called new math – which has actually been around for over a decade – draw so much scorn from parents?
This new math is based on a list of standards that students should master within each grade. It’s different from “old math” in that the standards focus not only on the step-by-step procedures to solve math problems, but also on why those procedures work in the first place. The idea is to teach the procedures in such a way that children can apply this knowledge to future math problems that they encounter – both at school and in real-life contexts.
For instance, in solving the multiplication problem, 312 x 23, parents historically might line the problem up and start multiplying from right to left. We were told that we had to include the 0 on the right under 936, but I don’t recall ever being told why. But under the Common Core standards, students are encouraged to break the problem down into hundreds, tens and ones. This newfangled way to do the math makes it more transparent where the answer, 7,176, and that mystery 0 come from.
Overcoming math anxiety
Researchers haven’t completely figured out how to eliminate math anxiety. But as a researcher who studies why people hate math, I believe there are steps parents can take to combat any negative attitudes they may have toward math and to improve children’s math understanding. Five of those steps are listed below.
1. Point out math in everyday life
Math learning doesn’t happen just in classrooms. Parents can draw children’s attention to math all around them. They can talk about math in the grocery store or at the bus stop. One idea is to incorporate positive math talk while reading books with our children, even if the books don’t inherently include numbers. For example, even though the classic children’s book “The Very Hungry Caterpillar” doesn’t include counting or comparing how much the caterpillar eats each day, parents can insert guiding scenarios like “The very hungry caterpillar ate 4 strawberries. Let’s count them. 1-2-3-4. Did the caterpillar eat more plums or strawberries?” This is a “two-for-one deal” that could help time-strapped parents promote literacy and numeracy.
2. Play board games and card games
Children can learn about math as they play fun board games, such as Chutes and Ladders, and card games, like war. Research has shown that playing board games pays off. One study found that while low-income families played board games less at home than middle-income families, even one hour of board-game play across a period of two weeks increased low-income children’s math performance to the level of their middle-income peers.
3. Break math down step by step
To help kids avoid the COVID slide, a major dip in math performance occurring during the pandemic, parents can break down math problems step by step. As they learn the procedure at each step children can then better understand how to get to the correct answer, or where they made a mistake along the way.
4. Draw connections to more familiar and well-liked math
Parents can also help children understand more difficult math concepts, such as fractions, by drawing connections to more familiar, well-liked and less anxiety-provoking math, such as whole numbers or percentages. For instance, parents can show that ¾ – that is, three-fourths – is the same as 75 out of 100, or 75%. Parents can draw a connection to money, too. There are four quarters in a dollar. Each quarter is worth 25 cents. That means that three out of four quarters is worth 75 cents.
5. Avoid negative math attitudes
This recommendation goes hand in hand with our first recommendation. Parents should seek out opportunities to talk about math at every chance they get, but they should avoid negative math talk. Many an American will freely admit to being “not a math person”. These off-the-cuff remarks can have serious consequences for children, who soak up information in their environments.
Math-anxious teachers and parents can transmit their anxiety to children, especially girls. Girls and women have higher math anxiety, which could be one reason they have lower math performance and less confidence when estimating numbers and are less likely than men to pursue STEM careers.
I hope parents embrace their new role as math tutors, because it seems as if home schooling will continue throughout the spring for many students. It shouldn’t go unmentioned that kids aren’t all that enamored with their home-school teachers either. Some may even hope they won’t have the same teacher next year.

Majority of the lottery players play and buy lottery without a system or strategy. That is also why so many players ended up losing lots of money in lotteries. They just simply buy and simply lose! If you are a regular lottery buyer and wanted to make it big, then learn know how to pick winning lottery numbers.
If you spend too much, that may put a strain to your financial situation. On the other hand, if you spend too little on your Lottery game, your chances of winning the หวยออนไลน์ would be greatly reduced. So, you must draw a balance in this respect.
If you choose to play with the frequency theory, then you should select numbers that have been drawn most frequently in the past. If you prefer the averages law theory, then you should select the cold numbers.
In the area you live there are probably the same choices between small games with small prizes like pick thee games, five and six ball games with mid-range payouts, and the huge multi-state games with incredible odds against you.
Many lottery experts teach that it is better to pick the hot or cold numbers to have better success in the lotto. The hot numbers are the most frequent numbers and the cold numbers are the least frequent numbers from the past lotto drawings.
Statistic has shown that most winning lottery numbers have the combination of both odd and even digits. It is very rare to have a winning combination which consists of only odd or even digit. With a good lottery system, you’ll be able to eliminate numbers which have a slim chance of winning and produce combinations which have a higher chance of winning.
Popular numbers due to an event or occasion have equal chances of being drawn. They do not stand a better chance than any others. However, if you buy those popular numbers, since they are popular, they will normally have more players.
The above are the 4 practical tips to win the lottery that are fundamental to everyone’s success. Learn what you need to know, think smart, play smart and your dream to win the lottery would come true in the near future.


Calculators & more!
School: Richmond Middle School
Calculators become very expensive when you are buying a set for your whole classroom. Batteries go dead, calculators donât get returned, and unfortunately some get damaged. To solve some of these problems, I have decided to use a pocket chart that is labeled with numbers. This will help in many ways! When I take a quick glance at the chart, I will be able to see if any are missing. The pocket chart will help keep calculators in a safe padded space, not piled on top of one another or left on the floor. If I am one of the lucky winners, calculators will be purchased, pocket charts, and extra batteries.


A fun waste of a few minutes, The Eyeballing Game measures your ability to, well, eyeball shapes, distances, and other geometric attributes. I know, I know… “Math is hard!” But don’t worry, all you have to do is click and move a box.
My scores tend to be in the 3.5 range. For come reason convergence and triangle center seem to be my weak points. I can get them right, but when I’m wrong, they’re wrong!


If you have kids in grade school or high school, be afraid. If you have kids that have finished grade 12, be grateful.
The common core standards for math and English are going to turn today’s elementary schoolers into haters of education and then into haters of intellect.
Before that, they’re going to turn average learners into morons, morons into imbeciles and imbeciles into idiots.
Edu-fads have come and gone for years. Educrats pop them out in litters and the litters multiply like rabbits.
We had the new math. We had the new physics. We had the open classroom. We had the closed classroom. All of these gave individual school districts the green light to wreck minds. But you could escape. You could move.
Then we got “no child left behind,” “outcome based learning,” and now “common core.” These three are edu-fads that can wreck minds on a national scale.
Common core turns simple basic math and language into Rube Goldberg Contraptions of such stunning complexity that they’re guaranteed to fail. Cartoonist and humorist Goldberg made a point with his drawings. Hundreds of cartoons with the same theme. In summary: if you need to swat a fly, get a flyswatter and use it.
You don’t need great series of complicated steps and great numbers of moving parts to swat the fly. And you don’t need a great series of complicated steps and great numbers of moving parts to do simple math or read and write simple English.
Of course, Goldberg gave you the finished product. Teachers who don’t understand Common Core can’t do that. They’re too busy dimming their own bulbs to dim your kids’.
All math is counting. Get a bunch of blocks. Line them up. Give them numbers. Block 1, Block 2, Block 3, Block 4. There you have everything you need to know about numbers.
How many blocks? Four. That’s all you need to know about counting. Take away one block? How many left? Put it back in the line. How many now? That’s all you need to know about addition and subtraction.
Multiplication is shorthand for adding. Division is shorthand for subtracting.
C’mon, guys. This isn’t battlefield strategy or rocket science or brain surgery or any other of the current cliches for complicated.
To teach fractions, all you need is a pie crust. To teach decimals after dividing the pie, all you need is a ruler.
As for English: too many moving parts as it is. All you need is some simple basics. Words are the building blocks of sentences. Sentences are the building blocks of paragraphs. Paragraphs are the building blocks of everything else.
The most important sentence ever written in the English language is “See Spot run.”

Add or remove VAT in a click with our online South African VAT calculator. Simply enter the price and click the button. The current SA VAT rate is 15%.
Free South African VAT Calculator – Adding and Removing VAT Calculations
Add / Include VAT Calculator
Adding VAT means including the Value Added Tax (VAT) to the original price of a product or service. VAT is a tax added at different stages of the supply chain and is ultimately paid by the end consumer
Remove/ Exclude VAT Calculator
Removing VAT involves deducting the VAT amount from the total price of a product or service. This is done by subtracting/minus the VAT from the total. It helps to determine the base price of an item before VAT is added. Removing VAT helps to understand the actual cost of the product or service by excluding the tax component
VAT Inclusive Vs Reverse VAT Calculator
Let’s take a closer look at the examples: VAT, which stands for Value Added Tax, is a type of consumption tax that is applied to goods and services at various stages of production or distribution. Calculating the VAT amount can be done using two different approaches: the VAT inclusive formula and the VAT exclusive formula.
How to Calculate VAT Inclusive using the formula?
Tax Amount = ( Original Cost * VAT% ) / 100
Net Price = Original Cost + Tax Amount
How to Calculate VAT Exclusive using the formula?
Tax Amount = Original Cost – ( Original Cost * ( 100 / ( 100 + VAT% ) ) )
Net Price = Original Cost – Tax Amount
Understanding and correctly utilizing these formulas is crucial for both businesses and consumers. By knowing whether the VAT is already included in the price or not, one can accurately calculate the VAT amount and determine the total price. Proper VAT calculation ensures compliance with tax regulations and promotes transparency in financial transactions.
How to Calculate VAT Manually, you need to follow these steps:
Step 1: Determine the VAT Rate Identify the VAT rate applicable to the goods or services you are selling. For example, if the standard VAT rate is 20%, you will use this percentage in your calculations.
Step 2: Calculate the Net Price The net price is the original selling price of the goods or services before VAT is added. If the net price of a product is R100, proceed to the next step.
Step 3: Calculate VAT Amount Multiply the net price by the VAT rate. Using the previous example, R100 multiplied by 20% (0.20) gives you R20. This R20 represents the VAT amount.
Step 4: Calculate Gross Price Add the VAT amount to the net price to get the gross price, which includes the VAT. In our example, R100 + R20 = R120. Therefore, the gross price is R120.
Let’s illustrate the calculation with an example. Suppose you own a small business selling handmade jewelry. You sell a necklace for R50, and the VAT rate applicable to jewelry is 10%.
Step 1: Determine the VAT Rate: 10%
Step 2: Calculate the Net Price: R50
Step 3: Calculate VAT Amount: R50 x 10% = R5 Step 4: Calculate Gross Price: R50 + R5 = R55
So, the gross price of the necklace, including VAT, is R55.
Frequently Asked Questions

Staying awake wasn’t a problem when I was younger. Before the exercise regime demanded alarms set at 4am, my commute changed from one hour to two, and before I had a baby. Now, when it’s my turn to get my daughter to sleep, after the storybooks and lullabies, I pretend to sleep so that she will drift off. The only problem is that I sometimes follow her to lala-land.
Last night, I found the solution: a counting game.
Try counting up until you hit a prime number. Next, count back down, skipping all numbers that are not ptime numbers until you get back to one (I know that one is not a prime number, but for the sake of counting from one, let’s pretend that it is). After that count up again until you hit the next prime number. Then come back down. So a sequence may look like this:
And continue on like this. If you lose your place, start over at the beginning. It also helps me to move my foot to the beat of my counting. And try not to imagine the prime numbers as sheep. That’s going to accomplish the opposite of what you’re going for.

With this calculator, Hewlett Packard tried to conquer new fields of use. With the HP 16c it was for informatic engeneers possible to calculate like their computers.
There were different number systems available, like binary, octal, decimal and hexadecimal. You could change at every point the visual display into another number system or change between the number systems. The calculation operations are equal to the basic operations from processors. You can test programs up to 200 steps.
The user can also define the register length between 8 and 64 bits and can decide if calculation should be with algebraic or binary complement.
With my first assembler programs, the HP 16c helped me a lot. The development tools in that time were not as comfortable as the actual ones - in no way! To find errors was pretty lame. There it was great if you could know for sure, that parts of the program worked well.
It was also possible to calculate like with a normal calculator, but only the basic functions. That was the reason why I always used this calculator in combination with the HP 15c.
A very special feature of this calculator is the power-need. I use this model since 25 years (state 2008) nearly every day and had not changed the battery once.
Together are both leprechauns an invincible team!

CogStat supports sensitivity power analysis. In a sensitivity power analysis, the question is what is the minimal effect size that would provide appropriate power with the given alpha level and sample size. In other words, in the current analysis, what is the minimal effect size that can be shown with appropriate power? Yet, in other words, what is the minimal effect size where the null hypothesis probably can be rejected (i.e., the test will be significant) if the effect is present.
CogStat will calculate the effect size given 95% power, 5% alpha, and the actual sample size.
Note that, in some cases, the modules that CogStat uses to get the power analysis done are occasionally unable to calculate the results. In those cases, CogStat informs the user that the power analysis could not be calculated.
Sensitivity power analysis is available for the following hypothesis tests (see also here):
- One-sample t-test (effect size in d)
- Chi-squared test (effect size in w (see the description of Phi φ for the w index))
- Paired t-test (effect size in d)
- Two-sample t-test (effect size in d)
- One-way ANOVA (effect size in eta-square and optionally in f)
