Short answer: Negative zero does exist, and is equal to zero.
Let's think in terms of a number line. We start off with a 0. To the right of 0 are all the positive numbers in order. 0, 1, 2, 3, 4, etc.
Now let's go ahead and add in the negative numbers to the left of 0.
..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ...
Now think about what the relationship is between any number and its negative. We see that given a number, n, and its negative, -n, we see that they are both n spaces away from 0 on the number line. It's just the positive one is to the right and the negative one is to the left.
Given this information, we need to look at negative zero. This number will be the same number of spaces away from zero as positive zero is. Confused? Let's simplify it...
How far away from zero is zero? It's 0 numbers away.
How far away from zero is negative zero? It's 0 numbers away.
From this it should be more clear that zero and negative zero are the same number.

actually there is a negative zero on the number line.
any number, positive or negative, times zero equals zero
