# Ch 14: Algebraic Expressions and Equations

Learn about the guiding principles behind algebraic expressions and equations, which can help you prepare for the math portion of the General Educational Development (GED) exam. Each video lesson is presented in a clear and easy-to-follow manner and is accompanied by an online self-assessment quiz.

## Algebraic Expressions and Equations - Chapter Summary

In this chapter, you'll learn how to solve both simple and more complex algebraic equations using basic mathematical principles. These include linear, quadratic, radical and rational equations, among other types. Each lesson will show you how to solve a different type of problem and is specific to the questions found on the mathematical reasoning section of the GED exam. Individual lessons will include topics in:

• Expressing and writing mathematical problems and relationships
• Understanding and evaluating mathematical formulas
• Collecting and combining like terms in an algebraic expression
• Simplifying algebraic expressions and equations
• Writing equations with inequalities
• Common algebraic equations
• Solving algebraic equations using addition and subtraction principles
• Translating words into algebraic expressions

### GED Math Objectives

The GED exam is a nationally established, high school equivalency exam that has been designed in accordance with the Common Core State Standards for grades 9 through 12. The 4-part test is taken on a computer and includes a mathematical reasoning section that requires 90 minutes to complete. Content emphasis is on algebraic and quantitative problem solving, with approximately 55% of the questions devoted to the former. Our video tutorials will cover all of the principles and topics found on the actual exam. Learning outcomes include the ability to:

• Define and apply the correct formulas to mathematical problems
• Define and evaluate algebraic expressions by replacing every variable with a given value
• Simplify algebraic expressions by combining like terms or removing grouping symbols
• Discuss inequalities, open sentence and true and false statements
• Distinguish among the different types of algebraic equations
• Identify the parts of an equation, and translate a sentence into an algebraic expression
• Solve one-step and multi-step algebra word problems
• Understand how to determine when a numerical expression is undefined

The mathematical content area on the GED tests a student's understanding of basic mathematical concepts, including those associated with critical thinking, problem-solving procedures and mathematical models. During the first part of the exam, test-takers will be provided with an on-screen, scientific calculator.
