1+2+3 is a sum, using sum as a noun to describe a sequence of mathematical

symbols, esp. using the + sign.

You may continue to argue that it is 2 sums, and ignore it's abelian

properties if you must, but you know, I think most people stopped listening

to you a while ago, so I doubt it will make any difference.

That's not my memory of the exchange. I rampantly delete e-mails, and

almost never keep mails I send, so there's no evidence either way.

'a' sum? How many would that be then?

The version of the language (English) that I use marks the definite

article 'a' with the number 'one'.

You know, I don't think my memory was flawed at all.

When applied twice.

So is "1" using zero applications of the operator.

Why can't you count to zero? It's less effort than you seem to think?

Abelian is irrelevant.

I think you mean /associative/ rather than abelian, an instead of

/purely an accident/ you mean /absolutely necessary in order to be

unambiguous/.
