“I hated maths when I first started Springboard but I have made great progress and now have 2 maths qualifications! Springboard has helped me build confidence in myself and my maths skills. I love my maths lessons now.”
“I have enjoyed my time doing maths at Springboard. I have learnt new things and now I can do more than I used too. Marion is a good teacher and explains things I don’t understand.”
“GCSE English has taught me a lot. From going in and not knowing metaphors, and many other language techniques to knowing how to use my imagination to express (myself). Not only do you learn new things but you make new friends and (have) a positive relationship with your mentor (tutor).”
“I’d definitely recommend Springboard because it gives you the chance to gain qualifications and learn new things. There’s forklift training and many other things that might suit you. For maths and English, I wasn’t too good to start off with but once I got comfortable with what I was doing I enjoyed learning and was really focused on my work which led me to passing my English. Overall Springboard is a fantastic place to learn new skills!”


Work problems are common in the workplace and they can cause stress. Luckily, there are some easy ways to solve them. The article is going to discuss a few common work problems that can be solved.
Time and work are in direct proportion
The term direct proportion is used to describe two quantities that change at the same rate. This means that the increase in one quantity causes a proportionate increase in the other. Hence, an increase in the number of workers results in an increase in the amount of work they complete.
The concept of inverse proportion is also a type of proportion. Generally, a decrease in one quantity results in a decline in the value of another. However, there are situations when the opposite happens.
In the case of a car, the quantity of petrol it consumes is directly proportional to the distance it covers. If the car travels at a speed of 100 km/h, it will cover 40 km in 2 hours. If the speed is reduced, the time it takes to travel the same distance will increase.
Similarly, in the case of a person, the amount of time it takes to travel a fixed distance is in direct proportion to the person’s speed. If the speed of a person increases, the time taken to travel a fixed distance will also increase. Ultimately, the person will travel twice as far in the same amount of time.
Likewise, in a business firm, the amount of work that is done is in direct proportion to the number of workers. If a person works for five days, he will earn roughly 2000 rupees. This amount will rise if he works for ten days. If he works for twenty days, he will earn around 2500 rupees.
Hence, the rate of a person is directly proportional to the amount of money it takes to pay for that person. A person can buy three pencils for fifteen rupees. A child can buy one pencil for five rupees. Likewise, a worker can make up to 2000 rupees for working fifty hours.
The terms direct proportion and inverse proportion are important concepts in mathematics. These concepts help solve various problems. A better understanding of these terms will help students in the future. A student can use this knowledge to obtain good marks. Therefore, a clear explanation of the concepts is essential.
Common workplace problems
Common workplace problems can be daunting to say the least. These include issues like lack of training and leadership. Luckily, a few tricks and tips can help you out.
First and foremost, you should make sure you’re hiring qualified employees. Second, make sure you do performance evaluations on a regular basis. Third, you should take the time to train your workforce on a variety of topics. Fourth, you should make sure that you have a plan for dealing with these issues. You don’t want to become stuck in a rut.
While the name of the game is to ensure your employees get their work done, the key is making them feel appreciated. The more motivated they are, the more likely they are to perform at a high level.
The best way to achieve this is to find a solution that works for everyone. For example, if you’re running a small business, you may want to consider hiring a receptionist to handle some of the more administrative tasks.
One of the most enlightening things you can do is to encourage open communication. This will allow you to better understand the needs of your employees, and help you improve your business in the long run.
The best solution is to hire an experienced consultant who will help you figure out the best way to implement this strategy. You should also conduct a comprehensive orientation to make sure you’re putting your best foot forward. You should also make sure you have a parking strategy in place so your employees can arrive on time.
The most important part is to find a solution that makes your business a happy, healthy and productive place. You can do this by encouraging collaboration, and making your employees feel that they’re valuable members of the team. The most effective solutions are the ones that don’t interfere with your business’s day-to-day operations. The most notable attribution goes to the right people, at the right times.
A lot of common workplace problems can be solved with the right technology and procedures. But you can’t afford to just throw the baby out with the bathwater.
Adding fractions to work problems
The process of adding fractions is one that is quite different from adding whole numbers. This is because fractions are more unpredictable and more difficult to grasp.
When you add fractions to a number, you have to make sure that you are renaming the fractions to the same denominator. This may require some extra steps. However, it is one that is required in order to understand how to add fractions.
Another aspect to be aware of when it comes to adding fractions is the negative factor. Most students do not understand that a minus sign can affect the entire numerator. This can cause confusion when you are adding and subtracting. You may have to simplify the answer before you can get to the correct result.
There are many ways to practice adding fractions. You can use games like BINGO and Tic tac toe to make the process more fun. Also, you can cut out objects from the real world to help your child build a stronger understanding of how fractions work.
In addition to utilizing games and manipulatives, you can also make your own worksheets for adding fractions. These can be created in a variety of different formats, including PDF and HTML. You can even create them in custom format if you prefer.
Word problems are a great way to practice adding fractions. These provide real-world examples of questions to test students’ knowledge of how to add mixed numbers with different denominators. There are also many other methods to practice this skill, such as coloring, pasting and modeling.
The most important thing to remember when it comes to adding fractions is to make sure that you are multiplying the denominator by the same expression. This will help you understand how to combine fractions to achieve your goal. It can be difficult at first, but with a little bit of practice and some strategies, you will get the hang of it.
It’s never too early to start practicing this skill. A solid base knowledge of fractions is essential for success in many jobs. You can help your children develop an interest in math by talking about it in everyday conversations.
Solving a shared work problem
A shared work problem is one that involves two or more people working together. This may be something as simple as filling a swimming pool or as complicated as writing a program. There are many ways to solve these problems. Some of them involve interpretive logic and rational equations. Some use fractions and others are designed to accommodate more than two people. The goal is to find the most efficient way to complete a task.
One of the most common combined labor problems is the problem of finding unit rates and then combining them to determine how much time it will take to complete a job. For example, if you know that drains will take 2 hours to empty a pool, and that hoses will fill the pool in six hours, you can use a combination of both to determine how many hours it will take to fill the pool. This can be done by subtracting the rate of a drain from the whole and adding it to the rate of a hose. By using this method, you can calculate how much time it will take to fill the pool and write a program.


Betting on the web casino can be a enjoyable and profitable experience, but it’s important to realize how to estimate the expected value in order to make the most of your wagers. Within this blog post, we will go over what anticipated worth is and how to utilize it when gambling in the casino.
What’s Expected Importance:
Anticipated value is actually a statistical idea that procedures the average result of a particular function. In wagering, the anticipated importance can be used to compute the normal money that you will definitely win or get rid of on a option. To compute the expected worth, you only multiply the prospect of an occasion developing by the amount of money which you will acquire or get rid of if this does occur.
Establishing Anticipated Value:
For example, let’s say you are gambling on a casino activity, and you also assume that you will discover a 50Percent opportunity that your staff will acquire. If you bet $100 to them plus they do indeed earn, then you definitely will receive $200 back from the wager (your initial $100 plus your winnings). Because of this your expected importance for this wager can be $100 since which is the typical sum of money that you will definitely earn or lose.
Now let’s say that you think there is just a 20% probability your team will win. In such a case, if you wager $100 and they do turn out profitable, then you would obtain $250 back (your initial $100 plus your winnings). Even so, when they lose, you would simply get rid of your unique $100 bet. Which means that your expected benefit with this wager will be -$20 as you will probably lose money than to gain any.
As you have seen, calculating the predicted benefit can be a valuable tool when determining whether or not to position a certain guess. It is very important remember, even so, that this anticipated importance is only an average and does not ensure which you will earn or drop some cash.

“Compound interest is the most powerful force in the universe.” Some people attribute this phrase to Albert Einstein himself, although in reality its origin is not clear. But there is no doubt about its accuracy.
If there is one tool that can make a difference to your finances, it is compound interest. Thanks to this, your money will work for you and your savings will multiply little by little without you having to do anything except be patient and disciplined.
What is compound interest?
What exactly is compound interest? Something as simple as reinvesting the profits generated by your investment. That is why the simplest way to define compound interest is to compare it to simple interest.
Simple interest is always calculated on the same amount invested and never generates new interest. To understand it better, imagine that you have 1,000 euros that you invest at 10% per year. In one year you have earned 100 euros that you use to treat yourself. The following year you invest the same 1,000 euros again. What will your profit be? The same as the first year and it will continue to be the same year after year. That is how simple interest works.
What if instead of spending the money you reinvested it? That is what occurs in compound interest: instead of spending the 100 euros of profit, you keep it and add it to the capital invested, so instead of investing 1,000 euros, you invest 1,100 euros and the profit is no longer 100 euros, but 110 euros. That’s how compound interest works and here you can see its effect.
|Initial investment in the first year
|Profit first year
|Initial investment second year
|Profit second year
|Total money earned (year 1 and 2)
The key to compound interest is that the interest you earn is added to the initial capital and generates a snowball effect.
How to calculate compound interest (formula)
The concept of compound interest is simple, but the calculation is not so simple. The formula for compound interest is:
Cf = Ci (1+i)ⁿ
- Cf is final capital.
- Ci is initial capital.
- i is the interest rate.
- n is the time the investment is held.
To make this easier, you can calculate the compound interest of an investment in Excel with the XIRR Function.
How does compound interest affect your savings?
Compound interest is what makes your money really work for you and helps your savings grow exponentially.
The legend about the invention of chess tells that an Indian king wanted to reward its creator by letting him choose what his reward would be. The wise man answered that he only wanted one thing: a grain of wheat that would double in value for each square of the game he had invented, starting from the first one. It was as simple as that.
In the first square he would receive one grain of wheat, in the second two, in the third four, in the fourth 8, in the fifth 16, and so on. He did not need to continue with his explanation. The king agreed to his request: wheat corresponding to the 64 squares of the board with each square having double the amount of the previous one.
It was agreed, so the monarch ordered that the wheat the wise man needed be gathered. He could not. There was not enough wheat in the granaries of the kingdom to pay the man. Do you want to know how many grains of wheat were in the last square of the board? 18,446,744,073,709,551,615 or more than 18 trillion.
That, but on a smaller scale, is what compound interest can do for your savings. And getting an investment with an annual return of 100% year after year is also the stuff of legends.
A practical example: from 10,000 to 50,000 euros.
This is not to say that compound interest does not multiply your savings. A more realistic example will help you understand how it can help you achieve your financial goals.
Imagine you have 10,000 euros and you invest them with an annual return of 7%. In the first year you would earn 700 euros. With compound interest, the profit in the second year would be 749 euros and your accumulated capital would be 11,449 euros. In the third year the interest would be 801.43 euros and the accumulated savings would be 12,250 euros.
What would happen if you left the money for 20 years? At the end of the period you would have 38,696.84 euros. And if you reached 25 years? Your capital would be 54,274.33 euros. Thanks to compound interest, the capital grows faster and faster due to the snowball effect.
It is like when you roll a snowball down a slope – it gets bigger and bigger with each turn. Just imagine that the snowball is your savings and the slope is interest and time.

Most of new investors want to confirm that if their investment can make substantial profits. It is easy to know the total sales but calculating the cost will be more complicated.
According to our experience in this business, Here we calculate the approximate cost of toilet paper productionfor you reference. Please note that there are many kinds of toilet jumbo roll with different quality and different price, the cost maybe different for different country. Here we just give a computing method. the DataSource is Chinese market.
Cost list of 1 ton toilet paper production:
Toilet Paper Jumbo Roll: USD1,060.00
Processing Charges: USD30.00
Electric Charge & Maintain USD8.00
Packing Charges: USD60.00
Rental Fee & Wages of Support Crew& selling expenses: USD23.00
The total cost of 1 ton toilet paper production: USD1181.00
If the weight of 1 small toilet roll is 100g, the cost of each roll will be 1181÷1,000,000÷100= USD0.1181
Now you know the total sales and total cost, then you know how many profits you can get from your investment

A hypothetical: you are a junior doctor at a local hospital and your senior asks you to administer an urgent drug for a sick patient. To add more complexity to this situation, you must figure out the drug dose in the next 30 seconds. Though, due to your extensive training, you easily work out that you require the weight of the patient and the drug’s initial concentration. You find the patient’s weight in the chart and prescribe as follows:
Patient weight (kg) x Drug (mg/kg) = Drug dose (mg)
Intense scenarios like these require the time-pressed quantitative skills — and surprise, surprise — are tested in the UCAT. Your exam might not be as exciting as working in the hospital, but you will need to work through similar calculations to score well.
Quick and efficient calculation skills can only be improved with practice. To increase your mathematical accuracy and speed, we suggest you study a range of different multi-step mathematical questions that require addition, subtraction, multiplication, and division. In the exam you will be given an on-screen calculator to use; however, some questions may be faster to calculate manually. The questions that require manual calculations will become clear with practice.
The type of questions you will face typically fall into a few groups (percentages, ratios, averages, and multiplication/division), each of which will require arithmetic. Since questions will be drawn from data presented, try learning how to skim data to identify the task required of you.

STEM (Science, Technology, Engineering, and Mathematics) education is crucial for fostering curiosity, critical thinking, and problem-solving skills from a young age. While it may seem challenging to introduce these concepts to preschoolers, the early years are an ideal time to lay the foundation for a lifelong love of STEM. Here are some effective techniques for introducing STEM concepts to preschoolers in a fun and engaging way.
1. Hands-On Activities:
Preschoolers learn best through hands-on experiences. Provide age-appropriate STEM activities that allow them to explore and manipulate objects. Simple experiments, building blocks, and puzzles help develop fine motor skills and introduce basic scientific principles. For example, use everyday items like jars, water, and food coloring to create a simple color-mixing experiment.
2. Storytelling with STEM Themes:
Incorporate STEM concepts into storytelling. Choose books that highlight basic scientific principles, technology, engineering, or mathematical concepts. Use characters and scenarios that captivate a preschooler’s imagination while subtly introducing STEM concepts. Engaging narratives help make abstract ideas more relatable and enjoyable.
3. Nature Exploration:
Take advantage of the natural world as a learning environment. Explore the outdoors, whether it’s a nearby park, garden, or even a nature walk around the neighborhood. Point out different plants, animals, and natural phenomena. Discussing the changing seasons, weather patterns, and the environment introduces basic scientific observations.
4. STEM Toys and Games:
Invest in STEM-focused toys and games designed for preschoolers. Look for building sets, puzzles, and games that promote problem-solving and critical thinking. Many educational toys are designed to introduce mathematical concepts, spatial reasoning, and basic engineering principles in a playful manner.
5. Simple Experiments:
Conduct age-appropriate experiments that preschoolers can observe and participate in. For example, create a “sink or float” experiment using various objects in water. This introduces the concept of buoyancy in a hands-on and visually engaging way. Keep experiments short, simple, and safe, focusing on the joy of discovery.
6. STEM Apps and Interactive Media:
Select educational apps and interactive media that introduce STEM concepts through playful interfaces. Choose apps that align with preschoolers’ developmental stages and provide interactive learning experiences. Many apps feature colorful graphics, engaging characters, and simple challenges that make learning enjoyable.
7. Incorporate Math into Everyday Activities:
Integrate basic math concepts into everyday routines. Count objects during playtime, while setting the table, or during a nature walk. Use simple math language to describe quantities, sizes, and patterns. Reinforcing math concepts in daily activities helps preschoolers develop a natural understanding of mathematical principles.
8. Encourage Curiosity with Questions:
Foster a sense of curiosity by encouraging preschoolers to ask questions. Respond with enthusiasm, and when possible, guide them toward finding the answers through exploration and experimentation. Asking “why” and “how” questions promotes critical thinking and curiosity about the world around them.
9. Collaborative Play:
Foster collaboration and teamwork through group play. Group activities, such as building with blocks or creating a simple obstacle course, encourage preschoolers to work together, share ideas, and solve problems collectively. Teamwork lays the foundation for future collaboration in STEM fields.
10. Role Models and Diversity in STEM:
Introduce preschoolers to diverse role models in STEM fields. Share stories and images of scientists, engineers, mathematicians, and technologists from various backgrounds. Representation matters, and exposing children to a diverse range of STEM professionals can inspire and broaden their understanding of potential future careers.

At random-number.org, we offer random numbers generated by a true random number generator (TRNG), also called hardware random number generator (HRNG). In contrast to TRNGs, computers produce pseudo-random numbers, which seems random to many applications, but they are not truly random. For many applications, including cryptography, simulation of complex physical systems, etc., the pseudo-random numbers are not sufficiently random, which have led many researchers to investigate the possibility of creating TRNGs.
To generate truly random numbers, every TRNG needs a physical source of randomness (also called entropy source). In this regard, the RandN's randomness comes from optical devices. Then, by applying proper post-processing algorithms, the observed physical randomness transformed into a sequence of truly random bits that can be queried by users. Also, we would like to emphasize that we do not keep the sequence of random bits delivered to users.

Abstract: - Data mining and machine learning has been an important research topic in recent years. The topic of sparsely distributed data and the various issues related with curse of dimensionality of high-dimensional data, make most of the traditional clustering algorithm, lose action in high dimensional space. Therefore, clustering of data in high dimensional space is becoming the hot research areas. Clustering in data mining can be used as a data exploration or future prediction tool. With the advent of raise in huge data or high dimensional data such as DNA arrays, Images or GPS data, bag-of-words document representation etc., the goal of clustering is to group multiple data points in such way that they can be represented more efficiently for better understanding of the data. In this context we study the pitfalls of high dimensional data clustering concepts and algorithms are discussed then we study the SSC, SSSC, SMRS algorithms. This paper offers a subset based algorithm for automatically determining the optimal number of clusters on high dimensional data. The Main aim of this paper is to design an algorithm with reasonable complexity which computes representatives and clustering high-dimensional data accurately. In this paper we have made the following contributions i.e. designing of algorithm which used the divide-and-conquer strategy, which can able to compute the representatives within reasonable time and this algorithm is named as Hierarchical Sparse representatives.


Diffusion in social networks has developed over the years into a large interdisciplinary research area with important links to sociology, computer science, economics, epidemiology, and mathematics. A flurry of numerous articles and recent books shows the growing relevance of this field.
The tutorial will evolve around the question: how do ideas and behaviors spread through a social network and how do we achieve optimal propagation of a new trend or a new product? The processes by which new behavioral patterns spread in a population have been an object of study in the social sciences for the last decades. Typical examples include the adoption of new technologies or innovations, the spread of a virus, or the popularity of a political leader. Inspired by empirical studies, some basic mathematical models have been developed to capture diffusion. The value of such models is that they help us understand better the diffusion mechanisms and make predictions about the success of a new product. In all such models, a user is influenced only by the behavior of its neighbors in the graph of the social network, i.e., his social circle. Hence, the propagation typically begins by a relatively small set of people who adopt the new product (early adopters) and then the spread continues as the remaining people adjust their behavior based on word-of-mouth effects.
In the tutorial, we will first introduce the various models that have been proposed in the literature. We will then study algorithmic and game-theoretic questions that arise naturally in this context. Namely, from an algorithmic point of view, we are interested in finding the most influential set of nodes in the network so as to maximize the spread of a product. Concerning game-theoretic aspects, we will consider models with two or more competing products that spread simultaneously over a network. In this case, we will overview recent work in the literature involving the properties of Nash equilibria in such games, as well as the computation of a firm’s optimal strategy, given the opponents’ choices.

Tim Prentice – BSc (Chemistry, Computer Science), NZCE Int (Engineering)
Whilst I enjoyed mathematics in school, it wasn’t until I could see the application in real world scenarios that I started to fully appreciate it. Learning about second derivatives to calculate the curvature of car panels or using the wavelength of sound and speaker dimensions to calculate the ideal speaker box were things I would never think of at school. Until I did a University Engineering Mathematics paper that is. I would’ve been much more interested in mathematics if I knew its application from an earlier date.
My career was to eventually fall into computer software development. Where maths and logic takes a crucial role between what is good written software and what is not.
Without an understanding of maths some software algorithms take literally days compared to some which take a split second. A simple example is summing prime numbers up to several million. A good algorithm knows that all numbers are either divisible by prime numbers or are prime themselves, and that you don’t need to go beyond the square root of a number to know if it’s prime. Primes can be common place in encryption algorithms, and search algorithms too are very important.
Then there is the mathematical understanding of the space in which you are developing. Companies such as TV Broadcasters need to keep in mind the restricted amount of space and memory on their set top box when you are, say watching sports. Without it the set top box might freeze up and you could miss your sports programme and the advertisers won’t be happy about that! The programmers here need to think about recycling used objects, using the smallest objects and the fastest least intense algorithms, and how to mathematically merge multiple TV streams so you get the best picture quality.
It’s a learning experience. But perhaps the most challenging of all is how to express complex mathematical algorithms in a robust concise way that anyone can understand it. That is truly is an art and takes many, many years to perfect.

A Fortran IV subroutine to solve large sparse general systems of linear equations. J.J. Dongarra, G.K. Leaf and M. Minkoff July, 1. Purpose The Fortran program ICCGLU solves a linear system of equations A*x = b, where A is a large sparse real gereral matrix.
The solution is found through an iterative procedure. "In C or Java, you just have functions" - this isn't correct. A FORTRAN function returns a value; a subroutine does not. All C-based languages, including Java, have both too. You can always return a value from a function.
I would say that a function with a void return is the equivalent of a subroutine. – duffymo Oct 10 '13 at Fortran or C/C++ are much more efficient but could take much longer to write and require function/subroutine to work with different formats of its arguments.

The method of AIQ BKR or 'the Qabalah of Nine Chambers' is often used to reduce large numbers to a single number from 1 to 9. To use this method, add up the individual numbers in each digit position of the large number. If this sum has more than one digit, then add these together. Keep adding in this way until only one digit remains. For example, the number 1234 reduces to 10 (1+2+3+4=10) which again reduces to 1 (1+0=1). After the final digit from 1 to 9 is determined, use the following table to deduce the occuit significante:

Interest is growing in decision making strategies and several techniques are now available. The assessment of priorities is a typical premise before final decisions are taken. Total and partial order ranking (POR) strategies, which from a mathematical point of view are based on elementary methods of discrete mathematics, appear as an attractive and simple tool to asses priorities. Despite the well-known total ranking strategies, which are scalar methods combining the different criteria values into a global index which always ranks elements in an ordered sequence, the partial order ranking is a vectorial approach which recognises that not all the elements can be directly compared with all the others. In fact when many criteria are considered, contradictions in the ranking are bound to exist and the higher the number of criteria, the higher the probability that contradictions in the ranking occur. The Hasse diagram technique (HDT) is a very useful tool to perform partial order ranking. The results of the partial order ranking are visualised in a diagram, called Hasse diagram. Incomparable elements are located at the same geometrical height and as high as possible in the diagram, thus incomparable elements are arranged in levels. The quality of a ranking procedure has to be evaluated by a deep analysis and by several indices, i.e. scalar functions that describe features of an ordered set and allow comparison among different rankings. For this purpose, new indices for ranking analysis are proposed here, compared with the ones found in literature and tested on theoretical examples and on real data.

Due to the pandemic, and not having the usual togetherness, I’m thinking about modifying my pie recipe. Instead of sharing one pie at the table, I’ll make three smaller pies. That way they can go to three different locations and still look nice.
This is for you math majors. My recipe is for a 9 inch pie. I am going to make 5 inch pies instead. So how much more filling do I need for two five inch pies instead of one nine inch pie.
If pies were perfect cylinders, and the crusts counted for nothing, a 9 inch pie would be almost 64 square inches (pi times the square of half of 9), and a 5 inch pie, almost 20 square inches (pi times the square of half of 5). So the filling for a 9 inch pie would fill three 5 inch pies.
But pies are not perfect cylinders, and the crusts do take up some space. So hopefully someone who has actually done this before can weigh in. If not, middle-school geometry will at least get you in the ball park.
actually even stickier - because the shape of a “pie pan” is not “standardized”
amazon search for 5 inch pie pan turns up several - and first issue: “nominal” size is not actual size, diameters usually refer to the outer rim diameter, not the bit you fill into…
Non math pie baker here. I follow a crust recipe. Then I follow a filling recipe. So, I would approach this as 2 recipes for 3 identical pies.
Are you using a topper on your pies? Filling, how many cups of filling do you use prefer in your pies?
Based on the size of your pies, the math as it were is much easier to calculate. But, I would make a dbl batch of pie dough. Fit the pies, then work on the filling based on cups.
I always make multiple batches of pie crust at once so I’m sure I’d have enough. The extra goes in the freezer for another time.
Off the top of my head - which is how I cook most of the time - I’d make 2 batches of filling. But it would somewhat depend upon the kind of pie. Something like apple I’d make extra cuz you can’t have to much filling. For something that you can’t really over fill, like pumpkin or cream, I might go with a little less so as not to have any leftover. If they pies ended up a little under filled I’d throw on some extra whipped cream.
THanks all for the advice and math! The pie I’m going to make is pecan pie. I typically toss the chopped pecans into the pan, cover with the liquid filling mixture, then top with half pecans in a nice circular design.
I think I’ll go with a double batch, and see where that leaves me. Any leftover can easily be baked in a little ramekin.
So the pies were a hit! I used two sheets of the Pillsbury pie crust. I rolled the sheet between parchment paper to make it a bit thinner. I was able to get two complete circles per sheet, and I pieced together a third crust from each sheet, sealing the seam with water.
I filled each shell with chopped nuts, topped them with the goo, and then finished with pecan halves. They looked and tasted great! (This is the unbaked photo.)
So it seems that six is the magic number for this recipe. Thanks for all your input!


Enjoy Learning Calculus with Calculus Interactive
What? Enjoy Calculus? Is it possible? Quite possibly. While many of our older and more experienced readers are well versed in its study, the concepts in Calculus are often difficult for newcomers to pick up. Well, the Calculus Interactive App ventures to help out the younger ones here on XDA by injecting a bit of fun.
Developed by XDA Forum Member neumedia, the Calculus Interactive App endeavors to help calculus students, especially beginners, to understand the concept and principles of calculus and the different methods of differentiation. The user interface is very cartooney, yet pleasant, and doesn’t overburden the student with walls of theory text books do. Instead, the app uses animations and voice-overs accompanied by a jovial piano tune to explain the purposes of differentiation, principles of limits, gradients and how to differentiate, covering the product rule, quotient rule, and chain rule. There’s also a selection of practice questions to help with the theory, along with worked solutions to explain how to answer the questions.
The Calculus Interactive App can be a very useful application for those who are learning differential calculus, as well as being useful to jog your memory on earlier theory. It’s well polished, well designed and well made, and compatible with Android versions 2.2. So if this interests you, make sure to check out the original thread for more details.
