From children to adults,
Brain training that makes math fun!

It is a well-known fact that Indians are intelligent.
In particular, there are quite a few Indians who have risen to the top of global companies in the IT and financial industries because they are good at arithmetic and calculations.
So why are Indians so good at arithmetic and calculations? The secret is that they learn the unique calculation methods of "Indian Vedic mathematics" from a young age.
In India, simple additions and subtractions, as well as complex multiplications, are calculated a little differently than what we usually learn in elementary school.

Using Indian Vedic mathematics, you can solve two-digit multiplication problems in your head in an instant.
This book is an introductory book that explains Indian Vedic mathematics in a very easy way.
It explains things step by step so that even those who are not confident in math can understand it easily.
We have selected easy-to-understand and fun calculation methods so that everyone from children to adults can learn them with enjoyment.
Let's awaken our brains by solving problems with our own hands! Learn Indian Vedic mathematics and you'll find yourself magically solving problems effortlessly.
It guides you to develop your calculation skills by starting with addition and subtraction and moving on to two-digit multiplication calculations.
If you follow along step by step from the beginning, you will soon be able to do two-digit multiplication calculations in your head that previously required a calculator.
As you turn the pages, you may find yourself loving math.

A warm-up exercise to wake up your brain!
Addition and subtraction calculations in Indian Vedic mathematics

Indian Vedic mathematics is widely known for its magical two-digit multiplication methods.
But this book starts with addition.
Addition, which is much easier to understand than multiplication, can be the best warm-up exercise to wake up your brain.
Even if you find math difficult or don't like math, you'll find the addition calculations easy to follow.
This book is structured in a problem book format that allows you to practice by solving problems by hand.
Let's put the correct number in the blank space.
As you move your hands and solve problems, your brain will gradually become more aware.
Now, let's enter the fascinating world of Indian Vedic mathematics.

In Indian Vedic mathematics, two-digit addition and subtraction consider 'exact numbers' and 'complements' to be important.
A perfect number is a number with 0 in the ones place, such as 10, 20, or 30.
And the complement is a number that is added to make a perfect number.
The reason these two are important is to make calculations quickly.
This is because if you remember the compensation and use the exact number to calculate, you can do mental calculations without having to think about carrying or borrowing.
For example, when calculating 56+38, keep in mind that if you leave it as is and calculate it, you will get 14 when you add 6 and 8, which are the units digits, so you will have to carry over 1 to the tens digit.
However, if we make 38 into the exact number 40 and remember that the complement is 2, we can immediately calculate the correct answer, 94, by subtracting the complement of 2 from 96, which is the answer to 56+40.
Subtraction can be done quickly in your head without having to think about borrowing by using the exact numbers and their complements in the same way as addition.

Learn in 3 easy and fun steps!
Multiplication in Indian Vedic Mathematics

The reason addition and subtraction are introduced first in this book is to wake up the brain and get used to calculating in a different way than what was previously learned.
A brain that has been awakened in this way will now have no great aversion to calculating two-digit multiplication using the Indian Vedic method.
At first glance, it may be difficult to understand why such a simple calculation would be made complicated.
However, I will explain it in three steps so that you can practice with easy calculations first and then easily do difficult calculations.
Let's learn Indian Vedic mathematics in an easy and fun way by practicing step by step.

Indian multiplication rules are so ingenious and simple that you might wonder if they are even correct.
For example, let's solve 16×14 using Indian Vedic mathematics.
First, multiply the 'tens digit' and the 'tens digit plus 1'.
Since it is '1×2', it becomes '2'.
Next, multiply the 'units digits' together.
Since it is '6×4', it becomes '24'.
Now, if we add '24' to the '2' we obtained earlier, we get '224'.
This '224' is the correct answer for '16×14'.
If you are new to Indian Vedic mathematics, you may find it quite confusing.
If you don't believe me, you can take out your calculator or write it down on paper.
No matter how you calculate it, the correct answer is 224.
Of course, not all multiplications can be solved in the same way.
Each multiplication method has conditions and can only be applied when those conditions are met.
This book introduces three multiplication methods and their conditions.
If you're ready to dive into the fascinating and fascinating world of Indian Vedic mathematics, open this book.
Once you've solved the problems on the last page, you'll be able to wield the magical Indian math at your fingertips.
