In view of the above wishes, this paper takes this as the subject to study, and the basic students who have tried it in many famous schools and schools with high social credibility have launched this set of "synchronous Olympic Mathematics Training", the contents of which strive to reflect:

Support the current teaching materials, the knowledge system is based on the content of the new curriculum standard Beijing Normal University Edition, expand the existing knowledge, attach importance to the spiral rise of knowledge, and cultivate students' abstract thinking ability while synchronizing with the teaching materials.

Paying attention to quality improvement is the premise of learning mathematics well, which is the starting point of compiling this series. In order to improve students' mathematics quality in an all-round way, this book is suitable for most students to learn and use.

Strengthening the training of thinking, the study of mathematics is the study of thinking. This series of books pays attention to the cultivation of students' systematic thinking in chapter arrangement, which can combine the characteristics of students' learning and form a systematic knowledge arrangement. In other words, we can take knowledge as a chapter, knowledge points as a section, from shallow to deep, and deepen at different levels, so that students' cognition is relatively complete.
