Stack

Hey all, I have a question.  I don't know if this is too vague of a 
question, and if answering it is providing too much help and I should 
just figure it out myself, but if you can give me a hint, I would 
appreciate it.  I'm just getting really confused trying to use a stack 
and an expression tree.  Maybe I'm going about it wrong, but couldn't you 
just use a stack?  It seemed pretty clear from the assignment that we 
would have to use an expression tree, but it seems a stack might do the 
trick.  Am I going to run into problems that I just am not forseeing 
right now if I use a stack alone?  Thanks for any tips.  I've been away 
from CPS for almost a year and am having a hard time getting my thought 
process back into it.  I really appreciate any tips.
