On Friday evening my son, a friend, and I spent quite a lot of time playing "24". It's really fun, but it can be frustrating.

                               

The object of the game is to make the number 24 by using the four given numbers.    7, 7, 6, 5 drove us crazy!  Sami finally got the solution.  Can you solve it?  Consider leaving the answer as a comment.

Here's an example of one way to solve for  1, 2, 2, 7. 

               7 - 1 = 6      2 x 2 = 4       4 x 6 = 24
