Unit 5 Properties

Front

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 does the equation 25 + x = x + 25 illustrate?

Back

This equation illustrates the Commutative Property of Addition, which shows that the order of addition does not affect the result.

Front

What is the result of multiplying any number by zero?

Back

The result is always 0. This is known as the Zero Property of Multiplication.

Front

What does the equation 3 + (12 + 8) = 3 + (8 + 12) demonstrate?

Back

This equation demonstrates the Commutative Property of Addition, showing that the grouping of numbers does not affect the sum.

Front

What is the Multiplicative Inverse Property?

Back

The Multiplicative Inverse Property states that a number multiplied by its reciprocal equals 1. For example, 3 x ⅓ = 1.

Front

Define 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).

Front

What is the Associative Property of Multiplication?

Back

The Associative Property of Multiplication states that the way in which numbers are grouped when multiplying 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 adding zero to any number does not change the number. For example, 5 + 0 = 5.

Front

What is the Identity Property of Multiplication?

Back

The Identity Property of Multiplication states that multiplying any number by one does not change the number. For example, 7 x 1 = 7.

Front

What is the Additive Inverse Property?

Back

The Additive Inverse Property states that a number plus its opposite equals zero. For example, 5 + (-5) = 0.
