Mathematics curriculum reform version A is a compulsory course, a term in the reform of new curriculum standards and a course type in the adjustment of curriculum structure. The antonym of compulsory is elective. The knowledge content of the same module, version A and version B are different. Some mathematical concepts in version A are less than those in version B; As the same knowledge point, they have different positions in the teaching materials.

Specific differences:

1, with different degrees of difficulty.

A version of senior high school mathematics published by People's Education Press is simpler than B version, except that the content of B version is more difficult than A version, the exercises of B version, especially the exercises of Group B of B version, are very difficult.

2. The editing module is different.

Version A is a traditional geometric method that uses axiomatic theorem as an auxiliary line to solve solid geometry problems.

Version B is a new content, that is, following the knowledge of the plane vector part of Volume One, using the method and concept of space vector to solve solid geometry problems, and using algebraic calculation to solve geometry problems.

3. Implementation in different regions.

Version A and version B are divided into "regions", that is, one version of textbooks is generally used in the same region.
