what is the case that oxygen's oxidation number isn't -2?

So oxidation is a theoretical representation of covalent bonds, showing the most likely location of the shared electron(s)?

This sounds like a bad question, but are the oxidation states have the minus sign (-) or plus sign (+) before or after the number? When we talk about the charges of the ions in class, we have used the signs after the numbers (2-). Is this the same for oxidation states or is like, (-2). I was also confused about the example about OH-. Wouldn't hydrogen have a 2+ or +2 charge instead of 1+ or +1 because hydrogen needs 2 electrons to fill the valance orbit?

Mr. Rourke has said to put the charges like 2+. I do not think it matters, people just have their certain preferences.

For ionic charges, we put the number first, i.e. 2-.
For oxidation states, we put the sign first, i.e. -2.
