Algebraic simplification algorythm wanted.

I'm looking for an algorythm, preferably in Prolog, for simplifying
an algebraic expression. My first attempts can handle expressions
of the form 2+a+3 => 5+a, but gets lost with 2+a+3+b+4. I know that
I could flatten the trees, sort them and then re-construct them,
but I need something that works for all sorts of operators and that
can be defined by simple rules.
