| May 27, 2017 at 5:11 | comment | added | user50190 | Oh! Now I see the difference between MO and Stackexchange, thanks! BTW, IT IS an interesting problem! It's from my friend, it's probably a problem of entrance exam for graduate school in Taiwan. | |
| May 27, 2017 at 5:03 | comment | added | Anthony Quas | So it's not appropriate because this site is for problems that arise in people's original research; and not answering homework/competition/exam problems. You probably could ask at math.stackexchange.com. BTW: which entrance exam was this? It's quite an interesting problem. | |
| May 27, 2017 at 4:51 | comment | added | user50190 | Sorry, I rarely use MO, could you tell me what kind of problem is appropriate to ask here, and why entrance exam or competition problem are inappropriate to ask? | |
| May 27, 2017 at 4:37 | comment | added | Yemon Choi | I don't think it's appropriate to use MO to get help with finding solutions for entrance exams or competition problems | |
