Can you use
the numbers on four cards to make up equations that equal the number
on a fifth card? In Fantastic Four, you win the game by making
the most equations.

Write down the
numbers on the four cards that the computer shows you. You will use
these numbers to make equations that equal the number on the fifth
card. Turn over the fifth card. The computer will give you five minutes
to write your equations. You get the most points for equations that
use all four numbers (and no points at all for using only one number).

Suppose
the four cards the computer turns over are: a four, a nine,
an ace (which is a one), and a two. The fifth card turned
over was a seven. Can you make an equation that equals 7 using
4, 9, 1 and 2?
