I don't know whether JavaScript implements infinite precision integers and full rational numbers. These would seem to be essential for a bright 13-year old, so that (s)he could play with number theory. Ditto with complex numbers & trigonometry, so they can play with stuff they learn in high school. This is why Maxima (free Gnu license) is a pretty good way to start.
The GNU Macsyma web site is http://maxima.sourceforge.net/ . It derives from DOE Macsyma. But now the Sourceforge site has a link to http://www.scientek.com/macsyma/main.htm . Who is ScienTek.com? Their Macsyma web pages and logo are the same as those of the former Symbolics. They also offer PDEase. Could they acquire the rights to Symbolics Macsyma? Apparently a Korean company, they also have products relating to chemistry and environmental safety. Gene __________________________________ Do you Yahoo!?
