 Welcome to the Teachers' Choice Software web site. Our FREE on line mathematics 'How-To' library is open 24 hours a day.  The ever-growing library now has 71 helpful topics, and every topic includes a free download!

Maths Helper Plus application topics are contained in the on-line help. These topics explain the mathematics with worked examples and are illustrated with colour diagrams. Also, there are many links from these topics back to the tutorial topics.

To solve a mathematics problem using Maths Helper Plus, first locate an application topic similar to your problem. Now print out or just read the topic until you understand what to do, then apply the topic to the problem you are solving.

Many of the applications make use of Maths Helper Plus 'template' files. These are similar to document files, except that you load them with the 'use template' command. When loaded, a template adds its contents to your open document instead of creating a new document. This means you can add several templates to the one document. For example, the 'Distance formula' application below makes use of the 'distance formula.tpl' template file which contains the formulas to calculate distances between points.

These are the ready-to-use applications that ship with Maths Helper Plus:
