You have two choices....punch yourself in the mouth or try to follow the math nerd technobabble below. Choose wisely!
There is a negative 00, it just happens to be equal to the normal zero. For each real number aa, we have a number −a−a such that a+(−a)=0a+(−a)=0. So for 00, we have 0+(−0)=00+(−0)=0. However, 00 also has the property that 0+b=b0+b=b for any bb. So −0=0−0=0 be canceling the 00 on the left hand side.

-1. Zero is neither positive nor negative. The definition of positive (resp. negative) is that a>0a>0 (a<0a<0), and it's obvious that 00 satisfies neither.

@YoTengoUnLCD When the answer says "negative zero," it is referring to the inverse of zero under addition, not literally a zero that is negative.
