Newbie question: is it possible to compute a math:list with cwm?

Suppose I wanted to sum the :balances of all the :acounts of a given
:Person. I believe that if I had a ?list of all the :account :balances,
math:sum would give me what I want:

   ?list math:sum ?n

would constrain ?n to the right answer.  But, how do I compute (constrain?)
?list in the first place?  Can this be done?
