Math Puzzles for the Clever Mind

Description

It's true--playing with numbers can raise your I.Q., and help you think more clearly! The most popular numbers games are math puzzles, and you've come to the right place to find 100 examples of the best. 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 very logical lions, but would be eaten quickly if there were only 15. Give your clever mind a mathematical workout. Test, prod, and stretch it to the outer limits. Careful, you might even be stumped! But guaranteed, you’ll enjoy every minute of it. Sharpen your wits on a combination of new ideas, favorites, and classic puzzles to which a little bit extra has been added. Some have surprise answers, but none involve advanced math. Try this one: Many years ago, a farmer had 200 shekels with which to purchase 100 animals. Cows cost 20 shekels apiece, pigs cost 6 shekels apiece, while a sheep could be purchased for a single shekel. Assuming that he had to purchase at least one of each of the three animals, and assuming that he had to use all of his money, how many of each kind of animal did he purchase?
