What does community property mean in math terms?

Answer 1

I believe you may be thinking of the commutative property. If so, it's a property of a binary operator (one that takes 2 arguments, like addition) that means changing the order of the arguments doesn't change the outcome.

For example, addition is commutative: 1 + 3 = 4 and 3 + 1 = 4. This works regardless of the arguments.

Subtraction, on the other hand, is NOT commutative: 1 - 3 = -2 and 3 - 1 = 2. In some cases (when the arguments are both the same) changing the order wouldn't matter, but the commutative property means that it works for any arguments, so subtraction doesn't have it.
