Steps to
follow
1. Multiply the first number by its
consecutive number.
2. Multiply second digit i.e. 5 by
itself and attach it at the end of the result obtained in the previous step.
e.g. 1. 752
Step 1 : 7 x 8
= 56
Step 2 : 5 x 5
= 25
Answer
is ; 5625
2. 1452
Step 1 : 14 x 15
= 210
Step 2 : 5 x 5
= 25
Answer
is ; 21025
(Nikhilam Method)
Steps :
1.
Make a partition and on the right
side of the partition there are two places as base 100 has two zeros.
2.
Difference less than base.
3.
Square the difference less than base, these are the last two digit
of square are write on the right side of the partition.
4.
Subtract difference from rest number.
e.g. 1. 962
step 1 : 96 - 4
92 / 16 = Sol. 9216
e.g.
2. 852
step 1 : 85 -15
70 / 225(carry 2 to the left and add to
70 to get 72 )
= Sol.
7225
