Open Source Symbolic Math Packages?
3Suns asks: "There are many proprietary symbolic mathematics suites available, including Mathcad, Mathematica, and Maple. Strangely, I can't find a single free software project with similar functionality. These programs are as ubiquitous in universities and engineering companies as they are expensive. Given the deep roots of open-source in higher education, what can explain the lack of free/open-source mathematics software?" We last addressed this question three
years ago, but a lot can change in that time. Has it?
Yes, maxima...

(giac, interestingly enough, runs on PDA's for a mobile solution...)
If you haven't found open source CAS, you haven't really looked...
For commutative algebra, for example, there's Macaulay2.
Maxima would probably be your best bet
It is an implementation of Macsyma written in LISP and will compile and run fairly well on almost any machine
The syntax is easy to learn and the program is fairly powerful yet approachable
Even if it's not exactly what you're looking for, it is an extremely valuable tool
Singular is really good for commutative algebra.
In Soviet America the banks rob you!
