Three.

There are not 20 ways - there are only 12.

Simple! -4-4-4-4-4 = -20

No. There are two reasons why. First, 20 +10+1+1=32, and that does not equel 24. Also you can think of it in a different way. 20 and the three ones (1,1,1) make 23 and that is not 24. You dont pay attention to the zero because zero is not worth anything!!!

1x36, 2x13, 4x9, 20+13. That's a few of them.
