Some mathematics problems must be based on certain principles of solving problems, that is, starting from “first consideration”. Otherwise, it is either unsolvable or incomprehensible, or the problem is incomplete. This year’s college entrance examination has ended and I have asked questions about students. (Article 22, Question 22) Answers To the situation, many students have failed to answer this question and are incomplete because they did not follow this principle. For this reason, I will use this as an opportunity to discuss problem solving.
