Question
i am weak in mathematics so what is the best way to calculate in mind that a thing which is of 63 and i have 100 so how much will be left?

Answer
If you're asking how to calculate in your head 100 - 63, the easiest way is to realize that the digits on the right need to add to 10 and the ones on the left add to 9.  3+7=10 and 6+3=9 so the answer is 37.  That works for 100, but really, it just take practice.
