An instructor at Boise State University offers his book on elementary algebra for middle school, high school, and college students. The book spans nine chapters and covers both pre-algebra and algebra topics. Clear explanations of polynomials, systems of equations, and exponential expressions are just a few concepts addressed in the book. A particularly useful chapter provides some suggestions for approaching and solving word problems, which are often quite difficult for students. In addition to the textual elements of this Web site, four interactive, online tools are available. These tools include a graphing applet, two prime number utilities, and a "quadratic equation solver/ plotter."
