Publisher's Synopsis
The most popular numbers games are math puzzles, and you've come to the right place to find them, with 100 examples to make you think. Here's an example: find the shortcut for adding 2, 3 and 4 to form 6 different 3-digit numbers. Or, try this one: what is the smallest number that when multiplied by 3 gives an answer consisting of all 4's? Other games and puzzles involve flipping coins, burning candles and taking apart a Rubik's cube in your head. (There's also a puzzle called Cubic's Rube.) Still others challenge you to nab a thief based on his lies, and figure out how a sheep survives in a pen with 16 very hungry but logical lions, but would be eaten very quickly if there were only 15.
