Yes. It can be an adjective (minus value) or preposition (two minus one), and more rarely a noun (the opposite of a plus).
No. You may be thinking of the rule that a minus times a minus gives a plus. So -1 x -1 = +1. Or you may be thinking of using two plus signs. E.g. 1 + + 1 This just means 1 plus the positive version of one. This is just one plus one.
