Which package is the best?

maxima, and fricas. you need a lisp compiler for maxima but it does have
an emacs interface. I have efricas. friCAS dumped with SBCL with and
emacs interface. this takes some work for friCAS; maxima should be
available with your package manager.

if you need more info just yell..

Thank you!
