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.
20 + 20 + 20 + 20 + 20 = 100

6! / (6*6) = 720 / 36 = 20

Simple! -4-4-4-4-4 = -20
6x2=12 12+8=20 20+4=24
(-4) - (4) - (4/4)

2 ones i think.... 50, 10, 10 ,10, 10, 10 or 20, 20, 20, 20, 10, 10

Oh, what a happy little question! You can make 50 cents using 5 cents, 10 cents, and 20 cents in three ways. You can use two 20 cent coins, one 20 cent coin and two 5 cent coins, or five 10 cent coins. Isn't that just delightful? Remember, there are no mistakes, just happy little accidents!
