Associative Property of Addition
The sum stays the same when the grouping of addends is changed. (a + b) + c = a + (b + c), where a, b, and c stand for any real numbers.
Associative Property of Multiplication
The product stays the same when the grouping of factors is changed. (a x b) x c = a x (b x c), where a, b, and c stand for any real numbers.
Commutative Property of Addition
The sum stays the same when the order of the addends is changed.
a + b = b + a, where a and b are any real numbers.
Commutative Property of Multiplication
The product stays the same when the order of the factors is changed.
a x b = b x a, where a and b are any real numbers.
Multiplicative Identity Property of 1
Multiplying a number by one gives a product identical to the given number. Also known as Identity Property of Multiplication.
Additive Identity Property of 0
Adding zero to a number gives a sum identical to the given number.
