qwerty {
That does not mean -0 is distinct from 0, which is essentially what Wikipedia is saying,
}

agree.

qwerty {
and what you keep misinterpreting:
}

No, qwerty, what I keep telling you is that -0 can never be a final answer. Try to read me well.

qwerty {
So is +5 incorrect too?
}

Yes!

qwerty {
So now you're saying that the actual problem is that the answer is not reduced
}

No, that's what I've been saying all from the start. -0 cannot exist, in a final answer. Let me remind you: When mirc yells sin(Pi/1) is -0, it's a wrong answer.

Are you going to continue trying this escape route pretending you have not understood the problem?
