I don't know if Armor/Magic Penetration "reduce" the enemy Ar/MR to less than zero, but lowering their Ar/MR work. I noticed it first with Morgana's W. Keep looking at your enemy MR and the dammage taken each second. The MR really goes lower than 0, and the dammage DO increase for that.

With Armor.... I haven't tested yet. And with the Penetration it might or not work as well.
