HOW TO FIND THE SQUARE OF A NUMBER WITHOUT CALCULATOR

Genius,do you know you can find the square of a number. Follow the following steps:

1.find the nearest ten the number of you are given falls to.

2.subtract the number from the original value.

3.subtract the result subtracted from the value the original value 4.square the subtracted result

5. Multiply the result gotten from step 2 and 3 then add the result gotten from step 3...THAT'LL

. For example : Find the square of 77,i.e 77^2 solution

77 is between 70 & 80 but it's closer to 80..i.e 80-77=3.

We subtract d result from the original valuei.e 77-3=74.

We square the subtracted result in step1..i.e 3^2=9.

Therefore (74*80)+9=5929..

Do you understand,if Yes then comment on the square of 32.i.e 32^2
