Online help almost always begins in the form of a question generated by you, the user. So what questions do you have? Good questions are always the first hurdle in the online world, but the second hurdle is how to deal with the results of your question. Type "linear equation" into google and you'll get about 2.5 million hits, but the quality of those hits will vary.

This page is intended to provide a set of links that I have found helpful for me and hopefully will help you sift through the exponentially growing amount of data available online. The first place you might start is with a "math" search engine rather than just google. I recommend starting with Wolfram|Alpha's search engine:

After trying some searches of your own, check out the different groupings of links in the picture below. The image below is a link to a whole host of helpful links. If there is a site missing that you know of or a site that you particularly enjoyed please let me know by leaving a comment below or by sending me an e-mail! If the image-link below is to overwhelming, I have narrowed the links down and sorted them in a more traditional way following this image.
