Yeah, it's a matter of convention rather than opinion really, but among US academia the convention is to exclude 0 from the naturals. I think in France they include it.

positive interers with addition are not a monoid though, since the identity element of addition is 0

I hope that explains everything

They're not a complete algebraically closed field either, but I don't see you advocating for including e - i in the natural numbers!

[–] SchwertImStein@lemmy.dbzer0.com 1 points 1 day ago (1 children)

yeah, this is kinda weak argument

[–] davidagain@lemmy.world 1 points 1 day ago

Not sure if you're conceding the monoid part or not.

We can agree that the natural numbers are a semigroup, I think, which should make us all happy.
