AEPA Middle Grades Math: Basic Algebraic Expressions - Chapter Summary

Explore and review the foundations of algebraic expressions as you prepare for the AEPA Middle Grades Mathematics exam. Rediscover what a variable represents and reexamine the purpose of constants and coefficients. These lessons will ensure you have a firm grasp of:

  • Variables
  • Algebraic expressions as a means of showing relationship
  • Simplifying, combining like terms and evaluating algebraic expressions
  • The commutative, associative and distributive properties

You can cover this material quickly by viewing our short video lessons, and video tags make review of a single topic quick and easy. The transcript provides immediate access to terminology. The self-assessment quizzes throughout the chapter are a great way to make sure you have a thorough understanding of the concepts as you study for the AEPA Middle Grades Mathematics exam. If you have any questions, our subject experts are available to help.

Objectives of the AEPA Middle Grades Math: Basic Algebraic Expressions Chapter

The AEPA Middle Grades Math certification exam will assess your knowledge of math concepts such as numbers and operations, algebra, functions, measurement, geometry, statistics, probability and discrete math. The material covered in this Basic Algebraic Expressions chapter is part of the Algebra and Functions domain, which accounts for approximately 33% of the NES Middle Grades Mathematics test, or about 50 questions. The self-assessment quizzes found throughout the chapter are a great way to become familiar with the question format and test your knowledge of the topics.

This exam has approximately 150 multiple-choice questions and a four hour and fifteen minute time limit. A formulas page, an on-screen scientific calculator and reference materials are provided for your use during the test.

What is a Variable in Algebra?

1. 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

2. 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

3. 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.

The Commutative and Associative Properties and Algebraic Expressions

4. The Commutative and Associative Properties and Algebraic Expressions

The order of operations is important and useful, but a few mathematical properties highlight cases where order doesn't matter. In this lesson, we'll learn about the commutative and associative properties, which may save you time and effort.

The Distributive Property and Algebraic Expressions

5. The Distributive Property and Algebraic Expressions

The order of operations is great. But sometimes we need to bend the rules to simplify an equation. Fortunately, the distributive property gives us a scenario in which this is okay. Learn all about it in this lesson.

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.
