Number Puzzles

Listed below are several puzzles that relate to numbers or mathematics in some way or another. Even if you're math-phobic, don't be frightened off by the word "Number" in the title. Many of these puzzles demand only a knowledge of basic addition or subtraction, and even some of those that don't aren't overly challenging and may be a fair bit of fun.
