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.

For the QRT 120 students, I have worked out several examples from homework assignments. They can be found by clicking here.

- Fractions, Decimals and Percent - This is one of MANY videos that I have available on these topics. More videos on these specific topics can be found on my YouTube channel by clicking any of the topics mentioned below.
- Standard and Metric Conversions - I also have additional videos on this topic. Click here for additional videos covering conversions.
- Ratios and Rates - This is one of several videos. Check out more videos on ratios and rates by clicking here.
- Volume and Area - This example is very similar to what you will see in your assignments. Check out my geometry videos by clicking here.
- Standard Deviation on Various Calculators - The calculator techniques for finding the standard deviation vary between each calculator. I show you several calculators in this video. I encourage you to use the calculator when finding the standard deviation because it is much faster when compared to manually computing it.
- Compounding Continuously and Understanding APY - Make sure to watch the last part of this video where I dive a little deeper into what APY really is.
- Net Monthly Cash Flow - You will see examples that are very similar to this tutorial in your assignments.

- Mortgage Payment - How do you type this long formula into the calculator?
- Using Taxable Income to Find the Tax Owed - Take note that this example also includes a tax credit.
- The Empirical Rule - This will be helpful with working with normal distributions. Remember... 68 - 95 - 99.7
- Charts and Graphs - Line graphs, circle graphs, bar graphs, etc. Many examples are covered here.
- Probability and Counting Rules - Examples using combinations are covered in this tutorial video.
- Probability vs. Odds - We will use a common odds problem that deals with scratch-off tickets.
- Probability and Rolling Two Dice - This is a classic probability problem.
- Exponential Functions: The Magic Penny Problem - You will see a very similar example in your assignments.
