Dear moderator,
I give some details:
I have to simplify a large expression of the type:

expr = P1(x)/Q1(x) + P2(x)/Q2(x) + ... Pn(x)/Qn(x)

where with x I have indicated the set of variable and P? e Q? are 
polynomials.
The ByteCount is about 500.000. I tried with different combinations of
Together, Simplify, Expand, ExpandAll but the program exited ( memory
increased till 80 Mb). 
I suppose that should be some way to cope with such large expression.
Isn't it?
Best regards
F. Renzoni
