Brief introduction to the real content of the high school mathematics Olympic competition
Mathematical Olympics is a mass competition with the widest coverage, covering almost every school in China. All kinds of competitions at all levels aim to broaden students' knowledge horizons, stimulate students' interest in learning, cultivate students' thinking quality and practical ability, and develop students' personality. At the same time, competition activities have played a positive role in improving teachers' own quality, promoting the in-depth development of teaching reform and improving teaching quality.

However, the content of competition questions is extensive, the proposition is novel, and the thinking is open, which requires students' comprehensive quality and innovation ability. However, when our parents see that their children can't do training exercises and want to help them, but they feel helpless, they will always sigh that they don't have a good book in their hands, which is either too difficult, too easy, too biased or lack of systematicness, and they will always be a little lost in the face of too many competition materials. Many of our teachers are also worried that there are too many books for the competition and there is a lack of a systematic book that does not exceed the outline of the competition. To this end, we have extensively collected and screened the test questions of mathematical physical chemistry competitions in some provinces and cities in China in recent years, summarized the test questions of national mathematical physical chemistry competitions, and absorbed some typical test questions of international competitions to compile this series. Through the comprehensive analysis and research of the test paper, this book makes a detailed analysis of each competition question one by one, striving to be easy to understand, convenient for students to learn by themselves and convenient for parents and teachers to refer to. This series of books strives to embody the following characteristics:

1. boot. It comprehensively reflects the questions, knowledge points and problem-solving methods of mathematical physics competitions in primary and secondary schools in recent years, and lets us see the trends and principles of future competition propositions.

2. novelty. The selected contents are all the international and domestic competition questions we have selected in recent years, which are not only new in content and questions, but also widely representative. After using it, you will find the content fresh, the topic novel, wonderful and interesting.

3. Exquisite. Because many test questions are difficult, but they are difficult and not strange; Flexible, high, climbing. Of course, when you answer, you have strong analytical reasoning ability and the ability to use knowledge flexibly. When analyzing, we should pay attention to making sentences popular and concise, and thinking clearly and simply. Some of them are also equipped with charts to facilitate students' understanding. For multiple solutions to a problem, limited by space, generally only one or two simplest and ingenious methods are used. This will be of great help to expand students' thinking, enlighten their thinking and develop their intelligence.

4. practicality. The first half of this series is a test question, which has room for answering, and the second half is an analysis. It can be used for students to test before the competition, and then master and understand the problem-solving methods according to the answers after the test. This is not only convenient for students, but also for parents and teachers to refer to.

5. authority This series was written by special and senior teachers and national excellent Olympic coaches who won the gold medal in the international Olympic Games in Huanggang.
