The associative property states that you can add or multiply regardless of how the numbers are grouped.

(3.5 + 2) + 4.5 = 3.5 + (2 + 4.5)
5.5 + 4.5 = 3.5 + 6.5
10 = 10

The commutative property states that you can add or multiply regardless of how the numbers arranged.

3.5 + 2 + 4.5 = 4.5 + 3.5 + 2 = 2 + 4.5 + 3.5
10 = 10 = 10
