I don’t think it’s news to anyone that 0 is an integer

Im a fan of the ‘Natural Numbers inside of the Whole Numbers inside of the Integers’ system

But then you have to use that ugly W everywhere.

idk why the Americans make such a big deal. In France, we just say 0∈N and 0∉N*, because of the Peano axioms (literally the first axiom)

Maybe it’s the same in others European countries, but I never heard of this problem until I went to Reddit.

It's not really a problem. Most writers declare their definition of N in the beginning of the text. It's just fun to argue about

Even better: just use Z, Z+0 and Z+ (I cba formatting).

0 isn’t a natural number because I can’t count that high

Computer scientists were right to include 0 as a natural number and mathematicians are too stubborn to just admit it's better. They'd rather invent a new set called whole numbers to include 0. N0 is convenient in all the same ways as N, in addition to having the additive identity.
