Have a look at:

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
