## commutativeTwo numbers, x and z, are said to be commutative under
addition if x + y = y + x
and to be commutative under multiplication if x × y = xy × yx
In general, two elements a and b of a set S are commutative under the binary operation (an operation that works
on two elements at a time) * if a * b = ab * ba
