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 Associative Property of Addition?

Back

The Associative Property of Addition states that the way in which numbers are grouped does not change their sum. For example, (a + b) + c = a + (b + c).

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is the Addition Property of 0?

Back

The Addition Property of 0 states that adding zero to any number does not change the value of that number. For example, a + 0 = a.

Front

How do you collect like terms in the expression 4y + 8d - 2y + 3d?

Back

Combine like terms: (4y - 2y) + (8d + 3d) = 2y + 11d.

Front

What is the quotient of a number n and 9?

Back

The quotient of a number n and 9 is represented as n/9.

Front

What does it mean for expressions to be equivalent?

Back

Expressions are equivalent if they have the same value for all values of the variables. For example, 2(x + 3) and 2x + 6 are equivalent.

Front

What is the Associative Property?

Back

The Associative Property states that the way in which numbers are grouped in addition or multiplication does not change their sum or product.

Front

What is the Commutative Property?

Back

The Commutative Property states that the order of numbers does not affect the sum or product. For example, a + b = b + a.

Front

What is the Distributive Property used for?

Back

The Distributive Property is used to multiply a single term by a sum or difference inside parentheses.
