Sorry if you know this one, but here's a small math puzzle that you can give to your opponents just before a teammatch and they won't be paying attention to the game. Bad idea: Give puzzle to your partner on the way to a big tournament.

Anyway, here it is.

Make 24 from the numbers 1, 3, 4 and 6. You must use all numbers and you can use the basic operations + - x / (possibly more than once). For example (1+4)x6+3 is allowed, but that would of course be 33 and not 24.
