How do I find the square root of 625 without a calculator? New math? I dunno. I try to work with easy numbers, like 200 and 25. Check the answer: 25 X 25 = 625. Where did the 400 come from? I just wanted to reduce the number to something workable. Otherwise, one can do the guessing game, but what if the number is really big?
