Do you often wish that you could remember the first seven digits of the value of the pi? It would be awesome. Here you have the chance to do the exact same thing.

Memorize the sentence “How I wish I could calculate pi”.

The number of letters in every word of this sentence is each digit of the value of pi.

The value of pi is = 3.141592

How = 3

I = 1

Wish = 4

I = 1

Could = 5

Calculate = 9

pi = 2.

How easy was that! Now you will never forget the value of pi up to seven digits. We hope your mathematical journey will win you a Fields Medal someday. In case you don’t know what it is, it is a medal for mathematics, which is as prestigious as the Nobel Prize.

]]>It is not a hidden fact, that solving mathematical problems, can be very challenging for some people. Therefore, we have come forward with a bunch of simple, yet tremendously helpful, tricks that can help you solve mathematical problems, without even having to do rough work. But for that to happen, you will still need to practice, using the tricks that we are going to teach you here. Once you are able to master these tricks, no one can stop you from being a mathematical genius in your

classroom for sure.

In this tutorial, we will be teaching you addition tricks, multiplication tricks, division tricks, percentage tricks, and much more. Before getting started, we suggest you get rid of all the distractions around you and give us your complete focus. If you feel like you will need to do rough work, grab a pen and a notebook in advance. Let’s begin!

Suppose you are given two large numbers, and you have to add them, what will you do? You’ll start adding them directly on a piece of paper without making it any easier. You have to round off those two large numbers and make them multiples of 10.

e.g. 137 will become 140 and 246 will become 250.

Now you can easily add these rounded off numbers: 140 + 250 = 390

But to get the accurate answer, you will need to subtract both rounded off numbers by original numbers, i.e. 140 – 137 = 3 and 250 – 246 = 4.

Round-off difference = 3 + 4 =7 which have to be subtracted from the sum.

Therefore, original sum = 390 – (3 + 4) = 383 which is the final answer.

So, you have learned here to add two large nmbers quickly. Now let’s learn how to do faster subtraction.

Some adults, and usually kids, get confused when we have to carry a number forward while doing subtraction, and it’s worst form is subtracting a larger number from 1000, which becomes very difficult. Therefore, a trick has been devised to do it very quickly.

You will only need to remember all the numbers other than the last number by 9, and only the last number is to be subtracted by 10. Let’s learn it via an example.

Suppose, we have to subtract 888 from thousand.

We subtract first and second 8 by 9 as per above rule, and the last number which is also 8, is to be subtracted by 10 only. It is a universal rule which you need to apply, whenever you are subtracting anything from 1000.

Therefore, the solution is 9 – 8 = 1

9 – 8 = 1

10 – 8 = 2

Your answer is 112.

]]>In our trick set #1, we have learned together to do addition and subtraction mathematical tricks so far. If you haven’t checked them out yet, please go and do it now, before moving on. Now, we will be moving on towards a bit more complex mathematical tricks, which will include useful multiplication and division tricks.

This trick will teach you to multiply any number five times straightforwardly.

Take the number you want to multiply by 5. e.g. 36.

Now cut your number into half, which in our case will be 36/2 = 18.

Just add a zero behind the half number, and you will get the answer which in our example is 180.

Here you’ll have to subtract your odd number by 1. For example, 7 – 1 = 6.

After that half the number you got, which here is 6/2 = 3

Now add 5 at the end of the number you got which becomes 35.

Thus, 35 is the answer in our case.

By learning this trick, you will be easily able to multiply any number by 9 without much hassle.

Let’s take a number, say 8.

We have to multiply it by 9.

For that, just subtract 8 by 1, so we get 7.

Therefore 7 is the first number of your multiplication.

Now, to get the 2nd number, subtract the first number that you got by 9.

It goes as, 9 – 7 = 2.

Combining the first number and second number, we get the answer which is 72.

After learning these tricks, you will no longer need to use hit and trial division method, and you can know in advance if a number is going to get evenly divided by a particular number. Let’s get the tricks started.

If any number has 0 at the end, it can be divided by 10.

If the digits of any number are added up, and the sum can be divided by 9, then the number will also be evenly divisible by 9.

If any number ends with 0 or 5, then it can be divided by 5.

If any number ends in 0,2,4,6,8, then it can be divided by 2.

]]>The most common mathematics related myth, is that people who are able to excel in mathematics, have some better mental hardware. But it is nothing more than a myth, which needs to be crushed. We, as human beings, are encoded by the same genes, and our mental abilities are pretty much similar. However, some people are also able to grasp things quickly, while some people are able to retain the concepts easily. But, every one of us is blessed with a unique ability, that you can use for your successful career. It is a fact that mathematics needs practice; you need to analyse, and then solve the problems. With much dedication and hard work, nothing is impossible to achieve.

Those people who are afraid of making mistakes are never able to achieve anything more significant in life. The most common reason for this hesitation is the fixed mindset, which needs to be changed to a growth type mindset. Students often make mistakes while solving problems, and develop an idea in their heads, that they are not doing well in this department.

]]>The number system is the most essential aspect of mathematics, and it is what we call the roots of mathematics. If you learn to play with the numbers and make sense out of them, there is genuinely nothing in the world that can stop you from pursuing a career in the maths department. Learning the numbers gives you access to learn every other so-called difficult portion of mathematics easily, such as algebra. Therefore, you need to study and practice the numbers, and clear all the concepts to such a level, that you should find it very easy to make numerical patterns and series. You need to be able to look at a bunch of numbers and make sense out of them. For that to happen, analysis and regular practice is a must.

]]>So far, you must have got the idea that mathematics is not just limited to dry textbooks. Let us address the role of mathematics in the finance and banking sector. You shouldn’t be of the notion that international commerce is not based on mathematics, because a central portion of the trade is mathematics. Mathematics always has a central role to play in predicting the rise and fall of stock markets. In fact, it is with the help of mathematics, that stockbrokers are able to make you a substantial fortune.

Stockbrokers and bankers use a diverse variety of mathematical tools to predict the market trends and compile complex statistical models, which helps them to know the financial details of the past. However, financial institutions haven’t yet learned everything they need to know, but it is definitely getting better nowadays.

The essential mathematical tools such as Black-Scholes equation, probability, Stochastic calculus and statistics are most extensively used in this sector.

In fact, there is a separate branch of mathematics dealing with the business, which we call business mathematics. It is used by firms for doing financial analysis, business forecasting, accounting, etc. Different universities and colleges now offer comprehensive courses to study business mathematics. It is not so well developed yet, because we are not able to use the mathematics in finance rightly, but things are certainly improving at a good pace. There are many unsolved financial problems in the market right now, and mathematicians are engaged in solving them. These are the things which mathematicians, as well as financiers, find difficult to comprehend.

]]>Not only that, mathematics has indispensable roles to play in many other diverse branches related to medical sciences, such as epidemics analysis, population dynamics, crowd control, neurology, plastic surgery and calculation of calories. So, what did we miss? You might say nothing, but there are many other contributions of mathematics in this field alone, and much other equipment used in healthcare centers operate on mathematical formulas. Therefore, we can say that mathematics has a considerable role to play in governing every aspect of our society, like every other scientific field, and what makes mathematics more unique, is that it always finds its way of applicability in every area of science, probably except the languages, which is very incredible.

]]>Now that we have completed the basic mathematical tricks, it is time to get into something more sophisticated. In this trick set, you will be learning some advanced mathematical tricks, such as percentage tricks, etc. So, tighten up your seat belts, and enjoy the mathematical ride.

We often get confused when we are asked to find the particular percentage of a number. Well, you will undoubtedly no longer need to worry about it after learning this trick.

Suppose we have to find 5% of 366, what do we do?

We just need to take 366 and move its decimal point by one place so that it becomes 36.6.

After that, we divide 36.6 by 2 and get 18.3% which, my friend, is also 5% of 366.

So far you’ve learned how to multiply by 5 and 9, let’s learn about multiplication by 10 and 11 now.

If you want to multiply any number by 10, just don’t do it. Just add 0 at the end of that number, you will get the answer.

For example, 15 multiplied by 10 = 150.

The multiplication trick for 10 was an easy one, let’s do it for 11 now.

Let’s take the number 15; to multiply it by 11, simply place the sum of its two digits between the two digits like this:

For 15 * 11, 1 (1 + 5) 5 = 165, which is your answer.

We hope you find our mathematical tricks fun and easy to learn, and we are continuously working to keep you updated with more mathematical tricks, in the next trick sets, which you can easily visit from this portal.
