squares and roots

     A square may be an unhip person--or it may be a fairly simple math term. A number multiplied by itself is "squared".
2x2 is 2 squared, or 4.
3x3 is 3 squared, or 9
4x4 is 4 squared, or 16.
5x5 is 5 squared, or 25.
The "square" may be indicated by a little 2 at the top of the number.
     A "square root" is the opposite, in a way, of a square, and has its own mathematical sign--like a long division sign, with a check at the end. The square root of a particular number is the number you could multiply by itself to get that particular number. For example--
the square root of 4 is 2, because 2x2=4
the square root of 25 is 5, because 5x5=25
the square root of 81 is 9, because 9x9=81
These are more difficult when someone hasn't chosen example that come out even. You might need a calculator.
