Will the opposite of zero always, sometimes, or never be zero? Explian your reasoning.

The opposite of zero will always be zero, because the opposite of 1 is - 1, opposite of 2 is - 2. Whereas there's only one zero not - 0 or something like that

The opposite of zero is 0. The opposite of a number is the number changing his signal.

0 is neutral, he's not positive and he's not negative, so, 0 and - 0 are the same thing, so always will be 0
