Mathematical Properties of Addition and Multiplication

Front

What is the Associative Property of Addition?

Back

The Associative Property of Addition states that the way in which numbers are grouped in an addition problem does not change the sum. For example, 3 + (15 + 4) = (3 + 15) + 4.

Front

What is the Multiplicative Inverse?

Back

The Multiplicative Inverse of a number is another number which, when multiplied together, gives a product of 1. For example, the multiplicative inverse of 8 is 1/8, since 8 x 1/8 = 1.

What is the Identity Property of Multiplication?

Back

The Identity Property of Multiplication states that any number multiplied by 1 remains unchanged. For example, 6 x 1 = 6.

Front

What is the Commutative Property of Addition?

Back

The Commutative Property of Addition states that changing the order of the addends does not change the sum. For example, a + b = b + a.

Front

What is the Commutative Property of Multiplication?

Back

The Commutative Property of Multiplication states that changing the order of the factors does not change the product. For example, a x b = b x a.

Front

What is the Associative Property of Multiplication?

Back

The Associative Property of Multiplication states that the way in which numbers are grouped in a multiplication problem does not change the product. For example, 2 x (3 x 4) = (2 x 3) x 4.

Front

What is the Identity Property of Addition?

Back

The Identity Property of Addition states that any number plus zero remains unchanged. For example, a + 0 = a.

Front

How do you identify the Commutative Property in an equation?

Back

You can identify the Commutative Property in an equation if changing the order of the numbers does not change the result. For example, 5 + 3 = 3 + 5.

Front

What is an example of the Associative Property in multiplication?

Back

An example of the Associative Property in multiplication is (2 x 3) x 4 = 2 x (3 x 4). Both expressions equal 24.

What is the significance of the Identity Property in mathematics?

Back

The Identity Property is significant because it provides a baseline for operations, ensuring that numbers remain unchanged when combined with their identity element (0 for addition, 1 for multiplication).
