#2) In the year 2,200 B.C.E., the first

"Magic Square" was found in China.

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?
