- defrost 4y agoTo be fair many of those "obvious truths" are rapidly discounted by the kinds of teenagers that go on to become university core math students. Fractal surface areas, the re-order of terms in an infinte series, infinite hotel questions, etc. were all high school puzzles in the 80s in my part of remote Australia so I can't imagine them stumping or confusing a university math lecturer.
