    What if the first number is odd?

      For example: 15^2 + 30^2

        15^2 + 30^2 equals 1125. You just follow the same trick, so 15^2 is 225, and you divide 225 by 2, yielding 112.5, and you multiply that by 10. I think Mr. Gillespy meant that adding the zero means multiplying by 10.

          Exactly. Adding zero means times 10.
