Combining Like Terms and Distributive Property

Front

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.

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

What is a variable?

Back

A variable is a symbol, often a letter, that represents a number in mathematical expressions.

Front

What are coefficients?

Back

Coefficients are the numerical factors in terms of an algebraic expression, found before the variable.

What is a constant in an expression?

Back

A constant is a fixed value that does not change, represented by a number without a variable.
