Free Computer Algebra
EigenMath is an easy-to-use free algebra and graphing package which is freely available for both Mac and Windows. While limited compared to a full computer algebra system (such as muPad), this is most suitable for early high school algebra.
For one of the best free mathematics tools, visit x-Functions Xpresso where you can use this wonderful software tool online, or download the java source for use offline. It includes 2-D and 3-D graphing, areas under curves, animations, derivatives, differential curves and much more!
SimCalc MathWorlds is probably one of the most remarkably powerful and exciting tools for teaching and learning mathematics that is currently available, and it is freely available for both Mac and Windows. This amazing tool brings together in one package all the best things about teaching mathematics: physical involvement, real world application, collaboration, narrative, the "big ideas" of graphing and calculus, suitable from upper Primary to senior years - the motto of this project: that mathematics should be "about something" is made real here!
xCAS offers interactive computer algebra, graphing, geometry, spreadsheet and programming! If you want some powerful tools for your students to access for FREE, then this is definitely worth a look - download the xCAS software for Mac, Windows and Linux! Terrible interface and even the English version needs a smattering of French, but the price is right!
