Written on the back of a tortoise shell, the puzzle revealed a square whose num- bers equaled the same amount whether added horizontally, vertically or diago- nally. Some came to believe that magic squares held secret powers, so the squares often were inscribed on amulets, to provide "good luck." More logical minds also have been attracted to magic squares; Benjamin Franklin liked to create them for fun. Try your hand at making a magic square (and if it's too easy, make certain that the numbers in each corner also add up to the same sum). Here's an example of one magic square: A) Take an ordinary 52-card deck. B) In "random order, turn over cards. Imagine that the first card is a 3. Set the 3 down, face up, then place on top of it enough cards to make a pile of 10. Suits and numbers on the cards atop the 3 do not matter. Simply place down the 3, then count 4,5,6,7,8,9,10 cards and stop. Continue doing this, making sepa- rate piles, until you have used all cards in the deck. Piles should contain more than 1 card, so simply place face cards and 10s back in the deck to be used for other piles. The ace counts as 1. C) When you have made as many piles as the deck allows (DO NOT include any piles which cannot be com- pleted to 10; hold any unused cards in your hand), turn all the piles over, facing down. Now, ask a friend to point to any three piles. Pick up the rest of the piles and keep the cards in your hand. Ask your friend to turn over the top cards on two piles, leaving one still face down. You are now about to reveal to your friend exactly what the hidden card is. D) In your hand you hold all the cards which could not be used to make piles of 10, as well as the piles that your friend did not select among his three. Count out the number revealed by your friend's top two cards. (Say he uncovered a 2 and an 8; you would count out 10 cards). Next, count out 19 more cards (this number will never change). Finally, count out the number of cards remaining in your hand. This is the number that also will appear on the hid- den top card. #5) How is it that 6 x 5 = 8 x 4?
