http://www.freemathvideos.com In this video you will learn how to solve and graph inequalities. When solving inequalities you will use the same inverse operations as solving equations. The difference will be when you multiply or divide by negative numbers you switch the sign. When then will graphing the solution we will use a number line.

A review of the proper names of some mathematical symbols
An updated version of graphing inequalities ( no music ) https://www.youtube.com/edit?o=U&video_id=HDq7l7CnN-A In this video, you will learn how to basics for graphing inequalities on a number line. Inequalities show that two expressions are not equal. For example, a number can be greater than, greater than less than, less than, less than, less than or equal to, and not equal to. When graphing the inequality on a number line you can use an open graph that does not include the number, and closed in which includes the number. You may also enjoy...
