    If you want to know how to do it mentally, it is 28^2-4^2=784-16=768

    yea that works but if you simply make it 25 * 32 which is simply 800 than subtract 32 its a lot easier to do in your head

    That's quite true. I memorize/calculate all the squares in my head between 1 to 110, so that's not much of a problem. They're useful for estimating square-roots also.
