    For + and -, figure out the x and y components of the angles/magnitudes via trig, add them together, them put the components back together to make the sum angle and magnitude.

    As for * and / I have no idea except something about magnitudes multypling and angles rotating...
    Don't pay attention to this signature, it's contradictory.

    I don't have an answer myself, but look into most books on 3D graphics, they tend to cover vector math.
    My usual boring signature: Nothing

    for vector multiplication, use the dot productor or the cross product. Look here
