9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
5 +9 = 9 + 5 is an example of arithmetic commutativity
It is: 80

2 + 5 + 9 + 12 + 16 = 44/5 = 8.8
9 + 9 + 9 + 1 + 6 + 5 = 39
5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 9 + 9 + 9 + 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 = 43
Yes because they all add up to 18
3 + 5 + 9 + 5 + 5 + 5 + 5 + 6 + 4 = 37
9 + 6 + 9 + 6 + 9 + 8 + 5 + 2 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 99
5 +9 = 9 + 5 is an example of arithmetic commutativity
9*5=45 or 5+5+5+5+5+5+5+5+5=45 or1*5*9=45
It is: 80
5 + 6 + 9 = 20
5+9+1 = 15
6(5 + 9) = (6 x 5) + (6 x 9) = 6 x 14 = 84
