You have recently become a teacher. You teach in schools, and in the summer you are a camp teacher. Today you got a job at a new school as a math teacher. The day went well, the children behaved calmly. It was a good school where many people wanted to work. Since each teacher has been assigned a class in which he will be a class teacher, then you have been assigned one of the classes. They were high school students. The students were good and studied well. One day, a guy came up to you after class while you were checking the work of other students. It was Maxim from your class. What does he want?
