validity
Commutative - (ANSWER)The order in which the numbers appear in the sum can be reversed
Identity property - (ANSWER)Adding 0 to any number does not change the original number
Additive inverse - (ANSWER)Values that are equally far from 0 on the number line.
Negative - (ANSWER)When multiplying a positive number by a negative number the result is always
Positive - (ANSWER)Multiplying a negative number by a negative number results in a positive
Factors - (ANSWER)Integers that evenly divide the initial integer
