One day, I have lunch back to the hostel to rest. We often need to do homework before the next break. That day I happened to do a math problem, I feel a little puzzled, thought for a long time have not thought out, and then I asked one of my roommates, and he gave me to explain the next, but still feels he does not, then, He was angry, and I do a lot of articles, and how could not correct it, I say not. He and I to an argument, no way, both of us fight for a long time, has no answer, the teacher had consulted. After a lunch break us, immediately to the teacher for help, we were none of the answers correct, we both had to silence, to learn the correct answer..
