352-8=344

Answer 2

1. every number which have 5 in the ones place have 25 in its tens and ones place when we square the number and also if it is 35 then the answer will be (3*3+3)and 25 if 2 then (2*2+2) and 25
Eg:- square  of 35 will be 1225
2.Squaring trick :-
 it is easy to multiply when units digit is zero.

For example - Find square of 43= (43+3) × (43-3) + (3×3)
=(46×40) + 9
= (460×4) + 9
= 1840 + 9 = 1849.
