Ch 13: Overview of Algebraic Expressions

About This Chapter

This chapter is to be used to study algebraic expressions. Take a look at techniques for evaluating and understanding math formulas, get practice in simplifying algebraic expressions, and more.

Overview of Algebraic Expressions - Chapter Summary

The lessons in this chapter are all about algebraic expressions. You will get to know the meaning of a variable in algebra and discover how to combine like terms in algebraic expressions. Additional lesson topics include:

  • Words translated into algebraic expressions
  • The use of algebraic expressions to express relationships
  • Evaluation of algebraic expressions
  • The simplification of expressions with negative signs

Each of these lessons is a 5-10 minute video that's hosted by one of our instructors. Short quizzes at the end of the lessons will assess your understanding of the material. You can make use of a feature we have that allows you to submit questions to a Study.com subject-matter expert.

Translating Words to Algebraic Expressions

1. Translating Words to Algebraic Expressions

When it comes to word problems, the easiest way to solve them is to look for keywords and change them into math symbols. Watch this video lesson to find out what keywords you should look for and what math symbols they represent.

Understanding and Evaluating Math Formulas

2. Understanding and Evaluating Math Formulas

With all the formulas out there, how do you know which one to pick? And how do you read formulas anyways? Watch this video lesson and you will find the answers to these questions.

What is a Variable in Algebra?

3. What is a Variable in Algebra?

Did you ever encounter something like a + b = c and wonder how all these letters snuck into a math problem? In this lesson, we'll learn about variables, as well as other parts of equations, constants and coefficients.

Expressing Relationships as Algebraic Expressions

4. Expressing Relationships as Algebraic Expressions

What do you do when you don't know what a number is but you do know how it relates to something else? You use an algebraic expression. In this lesson, we'll learn how to express relationships as algebraic expressions.

Evaluating Simple Algebraic Expressions

5. Evaluating Simple Algebraic Expressions

In this lesson, we'll learn how to evaluate algebraic expressions, which involves substituting numbers for variables and following the order of operations. By the end of the lesson, you'll be an algebraic expression expert.

Combining Like Terms in Algebraic Expressions

6. Combining Like Terms in Algebraic Expressions

When you have an algebraic expression that's much too long, it would be great if you could simplify it. That's when knowing how to combine like terms comes in. In this lesson, we'll learn the process of combining like terms and practice simplifying expressions.

Practice Simplifying Algebraic Expressions

7. Practice Simplifying Algebraic Expressions

In this lesson, we'll practice simplifying a variety of algebraic expressions. We'll use two key concepts, combining like terms and the distributive property, to help us simplify.

Negative Signs and Simplifying Algebraic Expressions

8. Negative Signs and Simplifying Algebraic Expressions

Don't let negative signs get you down. In this lesson, we'll stay positive as we practice simplifying algebraic expressions that have those tricky negative signs.
