"Algebrahelp.com is a math help site created to help people learn algebra in new and innovative ways. Our current content and features are the result of several years of development, design, and responding to the thousands of letters we've received on our work. The site has three primary features: Lessons, Calculators, and Worksheets. Each lesson walks users through the basics of a particular algebra topic, providing background, theory, and a few examples. Calculators enable users to enter their own problem, from a textbook or homework assignment, and instantly receive a solution along with a step-by-step explanation. Worksheets provide hundreds of sample problems, with answer keys, automatic checking, and step-by-step explanations, enabling students to practice and improve their skills."
