How to calculate 95 square as 9025 just like that?
This is how you do it.
suppose a number ends with 5 and you want to calculate the square of a number,
we the truncate the number's last digit which is 5 and multiply the remaining part with the subsequent number and put a 25 at the end.
suppose you want to calculate 85^2
8*9 = 72.
now put 25 at the end 7225.
Its as simple as that!!
Cheers!!
