Commutative property of Multiplication and Addition

Commutative property of Multiplication and Addition:

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.

  • Use the Commutative Property to restate "3×4×x" in at least two ways.

  • They want me to move stuff around, not simplify. In other words, my answer should not be "12x"; the answer instead can be any two of the following:

    4 × 3 × x

    4 × x × 3

    3 × x × 4

    x × 3 × 4

    x × 4 × 3
