What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the numbers being added does not change the sum. For example, 3 + 5 = 5 + 3.

Front

What is the Identity Property of Addition?

Back

The Identity Property of Addition states that when you add zero to any number, the sum is that number. For example, 9 + 0 = 9.

Front

What is the Commutative Property of Multiplication?

Back

The Commutative Property of Multiplication states that changing the order of the numbers being multiplied does not change the product. For example, 6 x 7 = 7 x 6.

Front

What is the Associative Property of Addition?

Back

The Associative Property of Addition states that the way in which numbers are grouped when adding does not change the sum. For example, (2 + 3) + 4 = 2 + (3 + 4).

What is the Identity Property of Multiplication?

Back

The Identity Property of Multiplication states that when you multiply any number by one, the product is that number. For example, 7 x 1 = 7.

Front

What is the Zero Property of Multiplication?

Back

The Zero Property of Multiplication states that when you multiply any number by zero, the product is zero. For example, 5 x 0 = 0.

Front

What is the Additive Inverse Property?

Back

The Additive Inverse Property states that for every number, there is another number that, when added together, equals zero. For example, the additive inverse of 5 is -5 because 5 + (-5) = 0.

Front

Rewrite (9 x 6) x 5 using the Associative Property.

Back

(9 x 6) x 5 = 9 x (6 x 5).

Front

What is an example of the Commutative Property of Addition?

Back

An example is: 4 + 2 = 2 + 4.
