9. show how you can solve these three problems using the order of operations and the commutative property. problem solve with: order of operations commutative property a. (-6) (4) (-2) b. (-1/4) (-1/2) (8)

A.  By using the commutative property, switch the -2 and 4.  By using the order of operations, you will multiply from left to right.
-6(-2)(4)
12(4)
48
b.  Switch the 8 and -1/2 with commutative property.  Left to right multiply.
(-1/4)(8)(-1/2)
-2(-1/2)
