Nope. Nothing is nothing - there's nothing positive or negative about it.
Peace!

There are two ways of looking at this question - one is to say that zero is neither positive nor negative and therefore there is no negative zero.
The second way is to interpret "negative" as meaning "the additive inverse of" (much the same way we would when talking about -1, -2, etc.). In which case the answer is yes -- zero has an additive inverse, which happens to be zero. Thus, -0 = 0.
Note that mathematically, -0 is in no case a number distinct from 0. However, there are some places where it may show up as distinct. For instance, in meterology, there are sometimes records kept of the number of days in which the temperature drops below zero. Occasionally, the measured temperature might read below zero, but not low enough to be rounded down to -1. In this case, it might be recorded as -0.

There is a mathematical system which had been developped by a high school student,dealing with the mathematics of zeros.
Never the less zero can represent the transistion between negative and positive values. It can also represent before an event that would start at time zero. So the time before zero starting point can be called time =zero minus.

In calculus, when you are doing limits, you need to know if the limit is approaching from the negative or positive side.
Limit of (1/x) as x approaches 0 is undefined.
Limit of (1/x) as x approaches 0 from the positive side is positive infinity.
Limit of (1/x) as x approaches 0 from the negative side is negative infinity.

I guess there theoretically could be one, it would just equal 0, because 0 has no opposite on the number line. So, even if there was one nobody uses it because it is terribly stupid, and why would it be better than plain old 0 anyway?

no zero is a neutral number it can be neither negative nor positive

there could be but you don't need it. zero is really neither positive nor negative.

the absence of any number including zero is called the "null set"
