Review Adding and Subtracting Algebraic Expressions

Front

What are algebraic expressions?

Back

Algebraic expressions are mathematical phrases that can include numbers, variables (like x or y), and operations (like addition or subtraction). They do not have an equal sign.

What are like terms?

Back

Like terms are terms in an expression that have the same variable raised to the same power. For example, 2x and 5x are like terms, while 2x and 3y are not.

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients (the numerical parts) of the terms while keeping the variable part the same. For example, 3x + 2x = 5x.

What is a constant in an algebraic expression?

Back

A constant is a term in an algebraic expression that does not contain any variables. For example, in the expression 5x - 9, -9 is the constant.
