Chapter 1

- Order of Operations - This link will take you to several videos that will help you with order of operations. There are several examples that cover the basics as well as handling fractions and decimals.
- Equations - Quite possibly the most important concept to master in an Introductory Algebra course. Several videos can be found here to get you comfortable with solving equations, including fraction examples and word problems.
- DMA 040 Review Video - This course is taught at another institution, but this video covers nearly everything you will see in Chapter 1 of this course.

- How to Graph a Line - These three videos will get you up to speed on graphing a line.
- DMA 050 Review Video - This course is taught at another institution, but this video covers nearly everything you will see in Chapter 2 of this course.

- Inequalities - You may have ran across some of these videos back in Chapter 1 when we talked about equations. Inequalities are the goal here!

- DMA 060 Review Video - This course is taught at another institution, but this video covers nearly everything you will see in Chapter 5 of this course.
