Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators
