The word commutative comes from commute in in the contacts needs to move around addition and multiplication artery arbitrate operations that are both commutative for addition the rules is a plus b equals b + 8 + example in a number would be 4 plus 2 equals 2 plus for both give 6s results for multiplication the world is a b equals to be a and example in numbers would be 4 times x equals 2x for the result in both cases is a subtraction does not have a commutative property because they be gives a difference result than does be minus a for example for - 2 equals 2 but - -4 equals 92 so in the case of the trash and move in the numbers around produces a different answer each answer in this case is the additive inverse of the other the Venturi operation and voltage subtract is therefore name anticommutativity
