## SQUARE MONEY.

(

Money Puzzles)

"This is queer," said McCrank to his friend. "Twopence added to twopence

is fourpence, and twopence multiplied by twopence is also fourpence." Of

course, he was wrong in thinking you can multiply money by money. The

multiplier must be regarded as an abstract number. It is true that two

feet multiplied by two feet will make four square feet. Similarly, two

pence multiplied by two pence will produce four square pence! And it

will perplex the reader to say what a "square penny" is. But we will

assume for the purposes of our puzzle that twopence multiplied by

twopence is fourpence. Now, what two amounts of money will produce the

next smallest possible result, the same in both cases, when added or

multiplied in this manner? The two amounts need not be alike, but they

must be those that can be paid in current coins of the realm.

## Answer:

The answer is 11/2d. and 3d. Added together they make 41/2d., and

11/2d. multiplied by 3 is also 41/2d.
