Hey, I've got one! Use the exponent operator.

  if (2^3 == 8)
      puts("two cubed is eight");
  if (5^2 == 25)
      puts("five squared is twenty-five");

That's Bitwise Xor not exponentiation.

2^3 => 1

5^2 => 7

It works though! And if you do

  if (2^3 != 1)
      puts("two cubed is not one");
  if (5^2 != 7)
      puts("five squared is not seven");

it prints those messages too.

The trick is operator precedence.

Cool - thought had operator confused
