1, with different knowledge contents:

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..

2, the problem solving method is different:

Version A and version B have different solutions to the same module knowledge. For example, version A uses pure geometric graphics to solve problems in solid geometry. And this block of version B is solved by vector method from the angle of algebra.

3. Different levels of difficulty:

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.

4. Different emphases:

Compared with version A, version B pays more attention to revealing the essence of concepts and improving mathematical literacy. Therefore, it is suitable for students who are interested in mathematics, while the A version of the textbook is suitable for self-learners or students who don't have so high requirements for high school mathematics. For example, it is also solid geometry, version A focuses on the examination of spatial imagination thinking, and version B focuses on the extension of concepts.
