1 + 1 != 2 if the 1s are magnitudes of vectors - if the directions are opposite, then they can be 0. In fact, 0 <= 1 + 1 <= 2 in that system.

That's not how addition works. You're either adding the vectors or you're adding the magnitudes. You don't get to sleight of hand by writing one and adding the other.
