Admittedly, mathematics always draws out the phenomena and laws in the real life and expresses it in a formal way, which, while bringing the students a sense of conciseness and clarity, at the same time pulls them out with mathematics the distance between. No wonder the well-known mathematical educator Freudenthal used to describe mathematical expressions like this: ”There is no mathematical idea published in the way it was when it was discovered. After a problem was solved, the corresponding development was a Form formal skills, the results of the process of solving
