24 Games
Can you take the numbers 21, 10, 5, and 3, and make the total equal 24 using basic arithmetic signs (*, /, +, -)? Each number may only be used once, and every number must be used.
For example, if given 2, 2, 4, and 6, the answer would be
6/2 = 3
3*2 = 6
6*4 = 24
2, 2, 4, and 6 were all used once.

3*2 = 6
6*4 = 24
2, 2, 4, and 6 were all used once.
