It’s pretty good. The first part of the book "A Complete Collection of Skillful Learning and Solutions for High School Mathematics" explains in detail the substitution method, definition method, parameter method, intersection method, geometric method, comparison method, comprehensive method, and analysis. method, expansion and contraction method, proof by contradiction, substitution method, construction method, combination method, discriminant method, identity method, accumulation method, accumulation multiplication method, grouping method, split term method, iteration method, ascending power method, descending power method, bundling There are 98 ways to cleverly solve the problems, such as the method, the blank method, and the indirect method. The second part of the book is about learning difficult points skillfully. In high school mathematics, as long as it is difficult to understand, remember, or do, there are clever methods. You can understand it at a glance and learn it instantly. For example, there are more than 70 difficult points such as "grasping both ends, looking at the middle, cleverly solving double or inequalities", "cleverly asking questions, judging the continuity of functions", etc., making learning mathematics simple and interesting for students! The third part selects 500 college entrance examination questions, all solved using clever methods! "Encyclopedia" includes all the contents of the textbooks from the first year to the third year of high school. If you master most of the tricks in the book, you can know the answers to the general college entrance examination questions at a glance.
