Features: With the deepening development of the national basic education curriculum reform, the implementation scope of the "Curriculum Standards" for compulsory education is gradually expanding. New educational concepts are being accepted by an increasing number of educators and the public, and China's basic education is undergoing profound changes. The core of this transformation, for teachers, is to change their role orientation; for students, it is to transform their learning methods. In line with this spirit and to adapt to the further development of curriculum reform, we made significant revisions for this reedition, based on extensive feedback from experts, teachers, students, and parents. This book is guided by the new mathematics curriculum standards and is organized chapter by chapter according to the new textbook system. Its feature lies in explaining each chapter's key points, difficulties, doubts, and key examination points in detail, with clear organization, thorough analysis, and systematically comprehensive example problems. The content mainly covers the fundamental knowledge, knowledge application, thinking methods, and problem-solving techniques that should be mastered in each unit. The analysis and treatment of example problems are particularly well-executed, not only providing appropriate hints and standardized solutions but also including post-solution explanations. These explanations reflect the author's insights and experiences in problem-solving, serving as a summary of their problem-solving expertise. Therefore, it can also be said that this book distills the essence of the author's practical problem-solving experience. In the explanations, the author concisely reveals the thought process behind clever solutions, demonstrates the flexible application of mathematical methods, provides transformed or extended forms and solutions for problems that can be converted or generalized, and points out potential incorrect solutions. This will inspire students, help them understand the author's intent in selecting problems, enable them to grasp the fundamentals, focus on key points, overcome difficulties, study methods, and apply one problem to represent a category. Ultimately, this will help students achieve the goal of learning from one example to understand many, and think broadly, thereby escaping the sea of problems and enlightening their minds. The supplementary tests are designed to reinforce fundamental knowledge, key points, and difficulties, and knowledge application, targeting the characteristics of each chapter. They include commonly used question types from various regions, incorporate new problems reflecting recent trends in middle school and high school entrance exams and college entrance exams, and add application problems closely related to production and daily life. The question types are highly diverse and comprehensive, aiming to help students consolidate knowledge and improve their ability to apply it comprehensively. When using this book, students should combine it with their textbooks to master the various applications and precautions of knowledge points. For key points and difficulties, they should conduct careful analysis and research, combining example problems to achieve deep understanding and firm mastery. When working on supplementary exercises, students should independently think, first considering which problem-solving approach and strategy to use, then implementing the solution while paying attention to its standardization. After completing the solution, they should compare it with the provided answer to understand why this answer is correct rather than another, why this method is chosen rather than another, and how else it could be solved? How can one think divergently from a single point? After class, students should repeatedly reflect on, analyze, and summarize certain key problems. They should actively ask questions and resolve issues promptly. Learning the "Curriculum Standards" and updating educational concepts is an ongoing process; the implementation of curriculum reform also requires continuous exploration and accumulation. The revision of this book is a concrete implementation of learning the "Curriculum Standards" and reforming teaching content and methods.
