Definately Maxima is the only way to go.  It's the LISP engine that
Maple and Mathematica are based on from MIT back in the day.  It was
semi-recently freed and it's really sweet.  It'll take some work (you
have to use clisp - the other LISPs are broken, and the GUI is a bit
clunkier than most), but it's quite nice.

A Pope has a Water Cannon.                               It is a Water Cannon.
He fires Holy-Water from it.                        It is a Holy-Water Cannon.
He Blesses it.                                 It is a Holy Holy-Water Cannon.
He Blesses the Hell out of it.          It is a Wholly Holy Holy-Water Cannon.
He has it pierced.                It is a Holey Wholly Holy Holy-Water Cannon.
He makes it official.       It is a Canon Holey Wholly Holy Holy-Water Cannon.
