It means teaching edition. Compared with version B, version A is simpler and requires less knowledge. For example, there is a difference between version A and version B in the first chapter. Version A did not learn the inverse trigonometric function and did not design the cotangent value of trigonometric function, but version B did. The content omitted in version A is knowledge closely combined with physics and chemistry.

In principle, the proportion of people at all levels in provinces (autonomous regions and municipalities) is: A 15%, B 30%, C 30%, D and E ***25%.

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, such as the classification of four prisms and the concepts of regular prisms and regular prisms in the first chapter of compulsory 2-space geometry, which are not only available in version B, but also used for exams, but not in version A..
