1. What is an Inequality?
An inequality is an equation that uses greater or less than symbols and is helpful in situations with multiple solutions. Explore inequalities, two-variable inequalities, and how to graph two-variable inequalities.

2. How to Graph 1- and 2-Variable Inequalities
The number of variable inequalities in an equation affects how it is solved and graphed. Learn more about the properties of one-variable and two-variable inequalities and how to graph them on number lines and coordinate planes.

3. Set Notation, Compound Inequalities, and Systems of Inequalities
To solve problems where there are multiple points that require inequality symbols, strategies for compound equalities must be used. Learn about compound inequalities and how to represent these problems through set notation and interval notation and how to use systems of inequalities to solve these types of problems.

4. Graphing Inequalities: Practice Problems
Whether an inequality has one or two variables is an important distinction when graphing these types of algebraic expressions. Learn more about when to use a number line or a coordinate plane when graphing inequalities by solving some practice problems.

5. How to Solve and Graph an Absolute Value Inequality
Inequalities express 'greater than' or 'less than' and are useful in situations where the maximum or minimum is known and can be solved like equations. Learn the rules for solving and graphing inequalities with one variable and two variables, including absolute values.

6. Solving and Graphing Absolute Value Inequalities: Practice Problems
Absolute value inequalities must be split into new inequalities in order to be solved. Explore the difference between an AND and an OR compound inequality and how to solve and graph them using a system of inequalities with practice problems.

7. Translating Math Sentences to Inequalities
Math sentences, also called word problems, can be confusing until they are broken down into simple math problems. Learn how to translate math sentences to inequalities by defining the keywords and symbols used in inequalities and isolating the variable so the equation can be solved.
