In response to Mr. Alper's question about the cards in the Numbers Challenge

There are twenty-four cards, and each card has four numbers on it. Some
examples of the cards: 1,2,3 & 4; 2,5,8 & 9; 2,3,7 & 8; 1,2,4 & 7. The
numbers on each card can be manipulated to reach every target number between
1 and 24 (actually between 0 and 24). The four-number combinations on the
cards were specifically chosen because they can reach 1 to 24. Not just any
ol' four-number combination will do!

You can also play a similar game with a decimal or a fraction and three whole
numbers. For example, use 2,3,6 and .5 to reach 1 to 24. Or use 1,3,6 and
2/3 to reach 1 to 24.
