Cute Puzzle Funny, this puzzle was circulated around the office yesterday. I saw this puzzle linked to here. Go play with it and then you can see how it works. Basically what it asks you to do always produces a number that is a multiple of 9, which can be proven easily. z = (10*x + y) - (x + y) z = (10*x - x) + (y - y) z = 9*x So the puzzle functions by just placing the same symbol at each multiple of 9. Still, it's a cute trick, since the puzzle actually changes the symbol when you reload it. :) [Surfin' Safari] 9:52:28 AM
