I would also suggest experimenting with Maxima and Octave. They are both easy to install. My impression is that Maxima is a computer algebra system that is similar in some respects to Mathematica, and Octave is similar to Matlab. Mathematica and Matlab are two of the primary commerical applications used widely in math departments at major universities. Even though high schools (or community colleges) might not be able to afford site licenses for Mathematica or Matlab, if students have some experience with Maxima, Octave, they might be much better prepared for a first encounter with Mathematica or Matlab. If someone from a major university could verify or expound on this impression between the similarities between Mathematica/Maxima Matlab/Octave, that would really be appreciated. I think I'm correct about this, but I'm not 100% sure! L. Prevett Mathematics Instructor Cochise College, Sierra Vista, AZ, US prevettl@cochise.cc.az.us
