Scientific Notebook Information
I have used Scientific Notebook (SNB) quite a deal when developing this site, especially in the "Advanced Calculus" sections. (For example, see Differential Equations).
Many of the pages were developed in Scientific Notebook, then converted to HTML.
SNB is software that incorporates the MuPAD mathematics engine and a Latex-based word processor. It has awesome power for doing mathematics and for producing text- and math-based documents.
You can get a free trial 30 day download of SNB from here:

Learning Computer Algrebra Skills
It's very important that students learn how to use math software packages. In the "real world", scientists and engineers use packages like MatLab, MathCAD, Maple, Mathematica and Sage to calculate answers to complex problems.
Our students should not only learn basic math skills, but also how to use math software to do more complex analysis.
