Putting aside your preposterous conclusions about my math-guyhood, negative zero very much exists in mathematics, it's just not distinct from positive zero:
they are both zero. The first Wikipedia article I linked says the same thing in the second sentence (and if you think it confirms your statement, I suggest you re-read it, although I suspect that will automatically invalidate the article, non-authoritative as it is). I'm genuinely curious as to which authoritative sources claim that -0 is undefined in mathematics.
