Learn to calculate. 10% armor penetration from the start. Means that 90% is still left. 40% of 90 is 36 (everyone agrees?), so we got 10% of 100% armor penetrated, and then 40% of the last 90% (so 36% of 100). 10 + 36 = 46. The other way around is also correct. 40% penetration from Last Whisper, of the last 60% another 10% is penetrated, makes 6%. 40 + 6 = 46.
