VEDIC MATHEMATICS: TRICKS AND IMPORTANCE

The concept of Vedic Mathematics owes it genesis to the Indian monk Bharati Krishna Tirtha, who wrote the book on vedic mathematics in the year 1965. This illustrative book contains a record of mathematical techniques which are claimed to be taken from the ancient Vedas and are supposed to contain every tenet of mathematical knowledge. These techniques or formulae, called Sutras in the book, help students solve mathematical problems in an easy and quick manner. There are a total of 16 Sutras (Formulae) and 13 Sub-Sutras (Sub-Formulae) in the book. When one uses traditional regular mathematical techniques in problem-solving, such techniques become time-consuming and complex which leads to further confusion and a later distaste for mathematics in the child’s mind. If a student is introduced to the concept of Vedic Mathematics at this stage, it can be rather helpful to his arithmetical development.

Using Vedic Mathematics’ General Techniques and Specific Techniques, numerical calculations can be done quickly. Bharati Krishna Tirtha asserted that there was no part of advanced mathematics that lay beyond the realms of Vedic Mathematics as explained in his book.                Vedic Mathematics is claimed to have been derived from the Vedas, the literal meaning of the term ‘Veda’ is ‘knowledge’. Since, Vedas are considered to be the source of all knowledge; it is believed that Vedic Mathematics is more correct and efficient than other traditional methods of teaching mathematical equations. Although, this concept has many critics but it cannot be said that Vedic Mathematics bears no credit of its own.

The techniques of Vedic Mathematics are quicker than usual methods and we can definitely solve mathematical numerical calculations efficiently. When using Vedic Math tricks, one can do mathematical calculations 10-15 times faster than the traditional methods of calculations. There are many tricks of Vedic mathematics that we can incorporate to solve numerical problems. Once students master these Vedic math tricks, they will no longer depend on any sort of calculators for complex calculations. Also, one more added benefit of these tricks is that these tricks prove to be helpful to candidates who wish to appear in competitive exams as well.  Here are some of the Vedic tricks, if not all, that we can practice which will help us in understanding the concept in a fairer sense:-

1. Squaring of a Number whose Unit Digit is 5

This Vedic Math trick enables you to quickly find the square of a two-digit number ending with 5.

For example:- Find the square of (55)2?

Step 1. 55 x 55=…25 (end terms)

Step 2. 5x (5+1) = 30

Final Solution:- 3025.

1. Multiply a Number by 5

We can take any number, whether it is an even or odd number, divide it by 2 and we will get accurate results.

For example:-

1. a) In case of an even number:-

    2464 X 5=?

    Step 1: 2464/2 = 1232

    Step 2: add 0

   Final Solution: 2464 X 5 = 12320

1. b) In case of an odd number:-

                 3775 X 5 = ?

                 Step 1: Odd Number; so= (3775-1)/2=1887

                 Step 2: As it is an odd number, so instead of 0 we will put 5

                 Final Solution: 3775 X 5 = 18875

1. Subtraction from 1000, 10000, 100000

Here is an easier and time-saving technique to subtract any number from 1000,10000 or 100000.

For example:-

What is 1000-573?

We start by subtracting each figure in 573 from 9 and then subtract the last figure from 10.

That is,

9-5=4

9-7=2

10-3=7

Hence, the Final Solution :- (1000-573)= 427

1. Multiplication of any 2-digit numbers (11-19)

This unusual trick comes in very handy for getting results when we have to multiply any two-digit number from 11 to 19.

Once you master this trick, you can keep that calculator aside and just calculate the outcome on your finger-tips.

For example:- Take two numbers , i.e., 13 and 15.

Question: Multiply 13 X 15?

Step 1: Add the unit digit of the smaller number to the larger number. Here, 15+3=18.

Step 2: Next, multiply the result by 10. Here, 18*10=180.

Step 3: Now, multiply the unit digits of both the 2-digit numbers. Here, 3*5=15.

Step 4: Add both numbers, 180+15=195.

Final Solution: 195.

This concept can be concluded by saying that although Vedic Mathematics is a bit unusual as compared to the usual ways in which we solve numerical problems, but once you master this technique, the overall efficiency and time management needed for solving mathematical problems will be maximized. There are ample benefits to this concept and schools must consider keeping this subject in their curriculum or parents must find a Vedic Mathematics tutor for their kids, as it is a skill worth learning.
