The Math 4 for Windows will be available in March of 2009. We are not accepting pre-orders at this time, but if you click on the mailing list link at the bottom of this page and then type in your e-mail, we will notify you as soon as that option is available.
Before viewing the samples (see "Sample Lectures " button below), you need to download the Flash 8 player. After you download the player, be sure to restart your computer so the program will work properly. Finally, you must have a high-speed internet connection to download the samples in a reasonable amount of time.
