Answer: Choice D) Commutative Property of Multiplication
-------------------------------------
The commutative property of multiplication states that a*b = b*a. In other words, it doesn't matter how you multiply two numbers. The order isn't important.
For example, 2*3 = 3*2 = 6
So that's why we're able to do x*y = y*x
Furthermore,
x*y*z = y*x*z
Only the x and y swap places
