5 + 6 + 9 = 20
9 + 9 + 9 + 1 + 6 + 5 = 39
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
3 + 5 + 9 + 5 + 5 + 5 + 5 + 6 + 4 = 37
6 + 5 + 3 + 2 + 9 = 25
6+9+7-5=17 that is the answer
44 - 9 + 6 + 5 + 4 + 32 + 5 = 87
3 + 6 + 9 + 22 + 28 + 1 + 6 + 5 = 80
4 + 5 + 6 + 7 + 8 + 9 = 39
9 + 8 + 7 + 6 + 5 + 4 = 39
3+6+5+7+(9-7)=23
It's a simple example of addition.The solution looks like this:10 + 9 + 7 + 6 + 6 + 6 + 5 = 49
