Object: Make the number 24 using all four numbers on a
game card. You can add, subtract, multiply, and divide. Use
all four numbers, but each number only once. There is at least
one solution to every card. Cards have three levels of
difficulty: 1Dot (easy), 2 Dot (medium) and 3 Dot (tough).
Example: If you are given these digits: 12, 4, 2, 18
4+2=6; 12-6=6; 18+6=24
(Note: You are able to include the sum, difference, product, or quotient to help you reach 24.)
