Lesson Summary: In this lesson, you'll learn what an expression is in algebra and why it is important. In addition, you'll learn how to identify the terms of an algebraic expression and the coefficients in front of the terms. This is very important material to master because virtually all algebra problems involve expressions. It will be important to know how to isolate terms and coefficients when working problems.

Also, when we begin to solve equations in future lessons, we will need to manipulate the terms in an algebraic expression. Because of this, these skills are essential to Algebra. The student will gain practice and confidence with these ideas with step-by-step example problem.
