Usually, there are six negative signs. Did you have a particular one in mind?

Are you asking what it represents or in what conditions that you use it? I don't know why it is there either, just trying to help clarify the question.

This question does not make a lot of sense. A better question would be: why is the moment of inertia tensor defined the way it is defined?
