Actually since the "Pre-Season 3" patch that changed the in-game shop, masteries, etc. Penetration in general works differently. % Penetrations (i.e.  Void Staff/Last Whisper) applies FIRST and the Flat Penetrations (i.e. Haunting Guise/Brutalizer) applies afterwards.

So the math instead becomes:

100 MR:

- 35% from Void Staff

-8% from Masteries

-28 from malady

-20 from Abyssal Scepter

The end MR number is "0" (due to resists not dropping below zero)
