6 + 4 + 3 + 4 + 4 + 5 + 4 + 6 + 5 + 4 + 8 + 4 = 57
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
7 + 5 + 4 + 5 + 3 + 4 + 6 + 5 + 4 + 5 + 6 + 4 + 7 = 65
3+4+6+4=17
6 + 4 = 4 + 6 is an example of the Commutative property of addition.
