Natural Numbers โ‰  Integers though.

In spite of that, I'm chuckling. Math can be funny sometimes ๐Ÿ˜‚

Positive integers are (a subset of) natural numbers

Why a subset? They're the same thing right? I guess it could be about the zero?

you answered your own question

Well what I learned in school was that zero was both positive and negative. I knew some people consider the natural numbers don't include zero, but I didn't know for some zero isn't even positive.

it is neither positive nor negative

I knew a physicist who considered 0 negative if she arrived at 0 coming from negative source numbers and positive if coming from positive sources.

Something something sampling rate

Some places (like France) talk about positive and strictly positive, others (like England) about non-negative and positive

Identical sets are considered subsets of each other.

[โ€“] ewenak@jlai.lu 1 points 1 day ago

True

But I don't think they would have said "a subset of" if the sets were identical.
