I never said it was easy. In fact, in some sense, the problem is much harder than you might realize at first. This particular rabbit hole goes down very deep.

I never said it was easy. In fact, in some sense, the problem is much harder than you might realize at first. This particular rabbit hole goes down very deep. I am not urging this family of problem on all high school students. Rather, on all prospective high school math teachers. They should be able to communicate the joy of problem solving and discovery to any of their students who show an interest and aptitude -- which means these teachers should have done some of this themselves.
