The so-called problem solving refers to the teachers and students in the teaching process, the problem as a medium, through the student’s independent analysis of the problem, analogy, assumptions, validation and other creative thinking process of solving the problem, it is the problem as a starting point to Explore the process, thus strengthening the process of reflection of the problem-solving skills. The teaching of problem solving can arouse students ’enthusiasm for creation, strengthen students’ dominant position in the process of learning, help to enhance students ’innovative awareness and innovative ability, and improve students’ mathematical application ability. First, create a problem situation, cultivate awareness of the problem
