It is +13 or -13 because:
+13 x +13 = 169 and -13 x -13 = 169
Remember a minus number times a minus number = a positive number.
Oh, and just in case it comes up, you can't have a square root of a negative number.

13 because 13 x 13 = 169. It's easy to remember that 13 squared is 169 and 14 squared is 196.
