2. Different teaching contents: Compulsory education mathematics courses mainly cover basic knowledge and skills such as integers, fractions, decimals, algebra, functions, geometry and statistics. To enable students to master basic mathematical thinking methods and operational skills. Senior high school mathematics pays more attention to the study of depth and breadth, including calculus, mathematical analysis, linear algebra, probability theory and so on.
3. The teaching purpose is slightly different: the mathematics course in compulsory education stage is mainly to provide students with good mathematical literacy and mathematical thinking ability, so that they can solve problems independently and reserve basic mathematical knowledge; High school mathematics is to provide students with more advanced mathematical ideas and methods to deal with more complicated mathematical problems.
4. Different teaching difficulty: Because of different subjects and different teaching contents, it can be considered that high school mathematics is more difficult than compulsory education mathematics.
