** Introduction**

This page is a work in progress. We are planning to add to and improve the content. Feel free to use what we have so far.

If you need help with the math part of chemistry, you have come to the right place. Note that this will not help you with direct chemistry topics, but will help you with the math required to solve various chemistry problems. Note that you do not have to be a student at WTAMU to use this math in chemistry help session. It was created as a service to anyone who needs help with the math part of chemistry.

If this is your first visit to our website, please read the **disclaimer**.

**HOW TO EFFECTIVELY
USE THIS
WEBPAGE:**

There are nine main math concepts shown below. These represent some of the common types of math problems that show up in various chemistry courses. You can pick and choose which math topics go with your particular chemistry problems.

Under each specific concept, you will find links to in-depth tutorials that will help you to learn and review the material. These tutorials come from the WTAMU Virtual Math Lab, which I created. Within these tutorials, you will find pertinent definitions, formulas, step-by-step explanations, an answer/discussion section with step-by-step solutions, and links to other credible webpages that can help you further with that topic.

In math, when you study a specific topic, a lot of times you
are incorporating
other mathematical topics into solving the problem. Some of the
tutorials
will overlap each other. This will help reinforce the concepts
you
need to know to do math in your chemistry class. Under some categories,
there is overlapping between the different levels (beginning, intermediate,
and
college) of tutorials. **Find the algebra level that agrees
with
you most and do the tutorials under that level.** If you
start below college level algebra, **make sure that you make your way
up through college algebra.**

**The math part of chemistry at this website is split into nine main
areas: **

***Note that not every math concept for chemistry is shown here, but we do plan to add some more topics at a later date.**

**Solving Linear Equations**

**Solving Quadratic Equations**

**Solving Polynomial Equations by Factoring**

**Solving Rational Equations**

**Solving Formulas in General**

**Logarithms**

** Basic Mathematical Computations**

This area contains basic math concepts. You
know, fun things like making sure you have the negative in the right
place
and remembering when you have to find the common denominator of your
fractions.
Don't worry, I have the utmost confidence that **you
will do much better with arithmetic than Calvin.**

**

** Exponents and Scientific Notation**

This area contains help in working with exponents and applying that to scientific notation problems.

You will find several levels (beginning, intermediate and college pre-req) of help in exponents. There will be some overlapping between the levels. If a topic has tutorials in more than one level, try going under the highest level first. If that is too hard for you, go to the tutorials of the next level down, if available. If that is too hard for you, go to the tutorials of the next level down, if available.

**Once you find a level to start with, make sure that
if it is below college level, in the end you work your way up to college algebra. **

The beauty of this is it is **individualized**.
You can **go at your own pace** at the comfort of your own computer. You
know better than anyone else what your algebra skills are.
