## What is the Algebra Coach?

The Algebra Coach is an app that can help you learn algebra. It explains algebra step-by-step exactly the way the teacher does. It is powerful but still easy to understand and use.

Download the Algebra Coach and try it free for three weeks. If you like it then you can buy it for \$24.95 – a fraction of the price of an algebra textbook.  And it comes with an electronic textbook! You can't get better value.

The picture below shows how the Algebra Coach works. Suppose that you are asked to

solve the equation   a x + b = c x + d,   for x.

The teacher says it can be done in three steps but you don’t know how or why. So ...

1. You type the equation into the Listbox.
2. You click ‘OK’.
3. The Algebra Coach displays a set of buttons that operate on equations.
4. You click the ‘AutoSolve’ button repeatedly.
5. With each click the Algebra Coach explains a step.
6. After the third step the equation is solved.

After any step you can press F1 on the keyboard and the Algebra Help e-book opens up right to the paragraph that describes that step in detail.  No more asking the teacher “how did you do that step?” Here is the e-book if you press F1 after step 1 – transposing.

The Algebra Help e-book also contains exercise problems that you can drag-and-drop into the Algebra Coach.

The Algebra Coach can also teach you how to manipulate an expression – simplify, factor, expand, complete the square, and so on. Click here to see an example of completing the square.

The Algebra Coach can also teach you how to prove a trigonometric identity. Click here to see details on that.

The Algebra Coach can solve every type of equation that you will encounter in high school or college algebra. Here is a (particularly nasty looking) rational equation. This equation requires about 20 steps to arrive at the solution and in step-by-step mode you would see all 20 of them. In result-only mode you see the result only. In exact mode the solution is shown as fractions. In floating point mode it would be shown as decimal numbers.

What you have seen is just the tip of the iceberg. The Algebra Coach can do much, much more. Let's get started!

• If you have an older version of the Algebra Coach (3.0 or lower) then uninstall it first.
