Memorizing the squares up to 31 is pretty easy as most young people should have the squares up to 12 memorized (in America- I believe it's 15 or 30 in India?), the squares in the teens are relatively easy, the squares of any even number can be 4 times 1/2 of the square of the number you're trying to squarezfolwickhttp://www.blogger.com/profile/05352858482047170834noreply@blogger.comtag:blogger.com,1999:blog-11439944.post-3771837272460471222012-07-09T21:18:47.148-07:002012-07-09T21:18:47.148-07:00This is a good method for a quick estimate.
