Order in which black cleaver reduction/pen applied with skills?

So say you have black cleaver, and then whack someone with wukong's armor reduction. How does that calculate out?

Percentage then flat.

As of season 3, all percentage armor reductions and shreds are multiplied (which is commutative anyway), then flat pen is subtracted from the resulting armor value. Passive armor penetration and shredding auras are applied always, while on-hit armor shreds don't apply until the next time the target takes damage (the damage comes before the shred debuff is applied).

So starting armor * 70% * 92.5% - 15 = effective armor after one hit from Q. It'd just be starting armor - 15 when calculating the damage of the first hit, since both Wukong's Q and the BC's passive are on-hit shreds.

Edit: Note that you add the debuff effects of the BC together, so the second hit (normal attack after a Q) brings their armor down to 70% * 85% - 15.
