OpenAlgebra.com is a free online algebra study guide and problem solver designed to supplement any algebra course. There are hundreds of solved problems, video solutions, sample test questions, worksheets, and interactives.
I originally I wrote this study guide to benefit our online algebra students. Online students seldom see problems worked out by hand. In addition, the videos were designed to supplement regular course instructional materials. It soon became clear that my traditional in-class students were benefiting from the material as well. With that I decided to open it up to everyone on the web as an open educational resource. I truly hope it helps.
