OpenStudy (anonymous):

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.

OpenStudy (anonymous):

'h' and '14' are both equal to 't'. Since they're both equal to the same thing, they must be equal to each other. h = 14
