In a board game, tossing an even number on the die means taking 5 spaces forward, while tossing an odd number means taking 3 spaces back. If the die has been tossed 11 times and the player has moved forward 31 places, how many even numbers hane been tossed?

8*5=40

11-8=3
3*-3=-9
therefore 8 even numbers have been tossed!
