thanks for your time.
the solution to question that i learnd is that
when you square a two digit number, the last digit of the result will be equal to when you square the last digit of the two digit number.
e.g.
square of 32=1024 and square of 2 is 4
so no need to calculate from 10 to 99 just calculate from 1 to 9 and you will get the answer.
