    Is there a term used to describe all number except the natural numbers?

    I don't think there's a term for this. I was thinking humorously unnatural numbers but alas this doesn't exist.

    One math website joked about it and said the nearest they could come to it were negative numbers...

    Wikipedia has a list of number types:

    Do you mean all real numbers except for the naturals? I suppose you'd denote it by ##\mathbb{R} \setminus \mathbb{N}##.

    There's really no notion of "all numbers" in mathematics, since "number" is mostly a colloquialism used to describe all kinds of unrelated things.
