Ch 27: NES Middle Grades Math: Basic Algebraic Expressions

About This Chapter

Variables show up as often as numerical values in algebra. This chapter can be used to review for the basic algebraic expressions questions on the NES Middle Grades Math exam.

NES Middle Grades Math: Basic Algebraic Expressions - Chapter Summary

In algebra, variables are the building blocks of entire equations, and students learning algebra will first need to learn the idea of introducing letters into their math problems instead of simply dealing with numbers. The video lessons contained in this section will provide a through review of everything involving the basic algebraic functions you will be teaching once you pass the NES Middle Grades Math exam. This chapter goes over the following:

  • Variables
  • Expressing relationships in algebra
  • Evaluating expressions
  • Commutative and associative properties
  • Distributive property
  • Combining like terms

Along with algebraic expressions, this portion of the Study.com course will assist you in remembering various properties of expressions. Our timeline below the video allows you to jump to any portion of the lesson you want to focus on in order to best prepare for the NES Middle Grades Math exam. A team of experts is also available for help with a single click of the mouse if you have additional questions about any aspect of the lessons.

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.
