Aug 18 at 2:41 comment added David Roberts @PietroMajer in that case, it's fine. Someone had flagged a previous comment that made the point much less nicely and I wanted to replace that with an informative and cheerful version.

Aug 17 at 14:24 comment added Pietro Majer @DavidRoberts I have the impression that "simple question at a pre-graduate level" just means it has a simple formulation by elementary notions, but not necessarily that it has a simple answer at pre-graduate level (like e.g. the FLThm).

Were you thinking of other StackExchange site for mathematics questions? Best of luck with your studies!
