I don't agree with the "therefore": you *can* get a number from an
operation carried out on non-numbers.

Here is an example: the sets {emptyset,{emptyset},a} and
{emptyset,{emptyset},b} are not numbers, for any sets a and b, but
(provided a and b are not equal) their intersection *is* a number (namely,
the number 2).
