How is this “not easy”?
I mean, this should be as easy as any percentage calculation of this kind.
Edit: Ah, you think the kid would find it difficult. My point is, that it’s a shame if they don’t have a fall back to basics procedure when the tricks don’t work.
- gus_massa 6y agoMy guess is that he can use the fallback when the calculation is not easy. The part that I find interesting is that for the 20% of an integer he uses a "shortcut", but for the 10% of a decimal he uses the "standard" procedure.
