Quantitative Aptitude: Speed Maths: Squaring by Vedic Nikhilam Method

• Here, we are introducing the Squaring of numbers closer to 100, 1000, 10000, etc in very speedy manner.
• Nikhilam Method was found in Atharva veda. It is also known as Yavadunam Formula

Method

a) Finding out the Square of 99 or (99)²

Step 1. Here, 100 is the nearest power of 10 which, we can take as ourbase.

Deviation of base is 100-1= 99

Difference is 1

We will subtract 1 from 99 and will get 98. ……………………………………a

Along with this square of 1  is 1, which will be written as 01 as we have two digit number…………………………………b

By combining a and b, we will get square ie 9801

b) (94)²= 88 36

c) (92) ²=86 64

d) (102)²= 104 04

e) (994)²=988 036

By regular practicing this method, one can easily find out square of nearest number of 10, 100, 1000, 1000 and so on.
