Below are links to web pages and videos that help explain the various assignments in our math courses. For each assignment, the links are not arranged in any particular order --so, for example, the 'hardest' one may be the first one listed. You'll just have to click through them and see. The blue icons (icon) are for videos, the orange icons (icon) are for web pages, and the "W" icons (icon) are for worksheets. If you click on a video and nothing happens then probably 1) you're not using the latest Flash player, or 2) your school or company has blocked the source (eg, YouTube or Google video).
