Features: Thanks to the readers' support, "Intermediate Textbook for Mathematical Olympiad" (3rd Edition) (abbreviated as "Intermediate Textbook") has been in print for over two years, with each volume being reprinted seven to eight times, and the total sales reaching nearly 200,000 copies. Achieving such success among numerous "Math Olympiad" books is indeed remarkable. The reason lies in its writing principles: "Based on the curriculum, exceeding the curriculum, strictly synchronized with in-class materials, easy to understand, both popular and accessible, yet meeting the basic knowledge requirements of various mathematical competitions." Of course, it is also related to the inclusion of abundant A and B sets of practice questions closely matched with the main content, providing readers with options. When writing the solutions for this set of practice questions, we followed the principle that the solutions for each lesson's exercises are closely tied to the content and examples of that lesson, without advancing basic knowledge prematurely. The solutions are chosen to be as simple as possible, making them easy to understand and accept. We provide diverse solutions to allow readers to grasp the material from different perspectives. The level of detail is appropriate, ensuring that readers can read it smoothly without feeling overly complicated. In the first and second grade volumes of junior high school, new "Self-Assessment Tests" for the upper and lower semesters have been added (with answers included). At the end of the third-grade volume, four new sets of junior high school mathematical competition questions (two from Sichuan Provincial and National competitions in 2001 and 2002) have been added (with answers), providing readers with self-assessment tools to evaluate their learning progress.
