Answer 2

Ok. So you have to look. Do you see any 'x' or 'divide' signs?

Answer 3

addition

Answer 4

Ok, so you know that associative property of multiplication is out of the question.

Answer 5

yes I picked C.

Answer 6

You're right because associative addition is where you add more than three numbers. Commutative is when you add 2 sums and come out with the same number, and it doesn't matter which way (4 + 2 = 6 = 2 + 4). Good job.
