It's not Zope per se, but I'd do it in Python -- objectValues()
returns a list, use len() to get its length, etc.

Or, for a more generic case, which would probably be done far better
in PythonScript (and completely untested):

<dtml-call "REQUEST.set('a',1)">
<dtml-call "REQUEST.set('b',2)">
<dtml-call "REQUEST.set('c',a+b)">
