Choose 6-8 math elites from each class at the same level. The students are the audience, and the host uses the projector to show the questions.

Required questions: each group has 5 questions, and each question has a score of 10. Players will answer.

Answer first: ring the bell (or light) to answer the question, and get 15 for the right answer and 5 for the wrong answer. Difficult questions can be answered by the sitting audience, and the correct answers will be added to the class.

Finally, the class with the highest score wins.
