Okay, I'll bite   :-)    I would say "right", and that Addition Functionalism
is correct. My proviso: the key factor is how explicit it is. If two planetoids
gently collide, their masses are explicitly added, but if Van Maanen's Star
and S Doradus each emit a certain but different number of photons in a
given second, then the addition is highly implicit (or hidden). 

At a different, higher level, an intelligent entity (from a crow to an advanced
AI) may map these environmental additions, but mostly only explicit ones, 
into mental sums or feelings of numerical quantity.
