Two oranges plus three oranges equals five oranges. Two oranges times three oranges equals...? That just sounds malformed. One can add objects but one can't multiply them, it seems.
I suppose one could do a Cartesian product of sets, though, and say that two oranges times three oranges equals six pairs of oranges. If you're a mereological universalist, the "pairs of oranges" might be genuine though unnatural objects; otherwise, you might take them to be abstracta. So addition is either more concrete or more natural than multiplication.
Is there a point to these observations? Not really. They just struck me.
