minus-squareewenak@jlai.lulinkfedilinkarrow-up5·2 days agoWhy a subset? They’re the same thing right? I guess it could be about the zero?

minus-squareewenak@jlai.lulinkfedilinkarrow-up3·2 days agoWell 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.

minus-squareewenak@jlai.lulinkfedilinkarrow-up1·20 hours agoTrue But I don’t think they would have said “a subset of” if the sets were identical.

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