[Axiom-mail] How to expand a fraction (like Maple does with 'expand')?

[Wiesner Thomas]

I'm sorry that i bug you with this (probably) simple problem:

How can i do the following (from Maple) in Axiom:

> expand(((-r1*r2*uoff)+((r2+r1)*r3+r1*r2)*ue)/(r2*r3));
                          r1 uoff        ue r1   ue r1
                        - ------- + ue + ----- + -----
                            r3            r2      r3

I've been trying and googling for hours. I've tried MPOLY but have only  
managed
to to pull one variable in front of the fraction and didn't find out how  
to split it up completely.

I found the MPOLY approach in the Rosetta pages  
(http://wiki.axiom-developer.org/RosettaStone)
but it doesn't do what i want.

This seems to be such a simple task and I can't find out.

I am writing a quit overview about CA Systems for hobby electronics and  
want to explain some usual tasks in different CA Systems.


   Thanks in advance,
