On this page, you will find several animated PowerPoint
presentations that help you to understand basic mathematics better.
They are easy to use and fun to watch, but it may take a while to
download for the first time. You may prefer to download the viewing
software when you are not in a hurry, and then enjoy the shows
later. Since PowerPoint is a Microsoft product, it will work better
with Internet Explorer.

If you do not have PowerPoint installed on your computer, you can
download the viewer below.

Download Microsoft PowerPoint Viewer.
