By some definitions, maybe. However, definitions that exclude it probably do so for a specific reason. It's more a fluke of categorization than a real world distinction. Those distinctions might be critical to certain logic systems, but even most people who use that definition recognize reality.

Zero is a number in more cases than it isn't. It is a symbol that represents a value. Just like infinity, it doesn't matter if 0 doesn't exist in physical reality. It's still a useful value in most cases.

Who told you that nonsense?

Zero is the absence of a number, or a placeholder, not a number 🤷‍♂️ there's been mathematicians arguing over this for years my dude

Yeah, in the middle ages.

It's just a thought experiment, chill out

0 ∈ ℝ

This is something I would do in school unironically.
