Not really a free version of Maple, but I use Maxima. You can find it
at:
http://maxima.sourceforge.net/
There you can do things like (just a simple, stupid example):
(%i1) diff(3*x^2,x);
(%o1) 6 x
(%i2) integrate(6*x, x);
2
(%o2) 3 x
(%i3)
(the spacing is a bit unfortunate in my email now)
Best, Roland
