Here are the rules:
1: I will post a question
2: You need to answer it
3: whoever answers it correctly, gets to post their own question.
4: YOU MUST HAVE ANSWERED A QUESTION CORRECTLY TO POST A QUESTION
5: Have fun
Edit! If your question is not answered in 10 guesses, give the answer and get a new question
Edit! (again) If another question is not posted, the person who came the closest (if possible) posts a question
