Math competitions often have the opposite problem. The Putnam competition, for example, often has a median score of 0 or 1 out of 120.
I'm not sure this is a good thing. Participating in a math competition and getting 0 points is pretty discouraging, in a field where self-esteem is already an issue.
Interestingly enough, the scores on individual questions are extremely bimodal. They're theoretically out of 10 but the numbers between 3 and 7 are never used.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
