Distribution and Combining Like Terms

Front

What is distribution in mathematics?

Back

Distribution is a property that allows you to multiply a single term by each term inside a set of parentheses. For example, in 7(y + 9), you distribute 7 to both y and 9.

What does it mean to combine like terms?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power. For example, in 5a - 3a + 2b, you combine 5a and -3a to get 2a.

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 a sum or difference.

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 3y are not.

What is a coefficient?

Back

A coefficient is a numerical factor in a term. For example, in 4x, 4 is the coefficient.
