In classroom teaching, we often have the feeling that many students still do not know how to start a training project when they finish the training. Students sometimes wonder why they always appear. In fact, the root cause of the above phenomenon is that we ignore the effectiveness of problem-solving teaching in the classroom.Mathematical problem-solving from getting the title to complete There are usually four stages to solve (steps): understanding questions, exploring ideas, writing solutions, reviewing reviews, and examining questions is understanding questions (or clarifying
