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

        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.

          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.

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

        True

        But I don’t think they would have said “a subset of” if the sets were identical.
