The new version of mathematics adds a chapter on quadratic function, equation and inequality, but the old version does not, but this chapter is still very important and plays a connecting role in junior and senior high schools.

The revised curriculum is divided into compulsory courses, elective compulsory courses and elective courses. Compulsory courses and elective compulsory courses are the content requirements of the college entrance examination. Elective courses provide guidance for students to determine the development direction, provide choices for students to develop their interest in mathematics, and provide reference for independent enrollment in colleges and universities.
