Hangzhou Yuhang Xinda foreign language junior high school mathematics test paper usually contains some Olympic math questions. What are the main knowledge points of this part of the Olympic math problem? I don't know about Hangzhou, but in general, the entrance examination questions of good schools will add Olympic math questions. Some schools in Chengdu will have more complicated score calculation in almost every exam-different questions have different methods, such as disassembly, area calculation-addition, subtraction, cutting and filling, rotating balance, amplification and so on. , and arithmetic progression's knowledge is almost compulsory, such as circulation problems, travel problems (such as more complicated encounter and chase problems). I believe that the topic selection method of Hangzhou test questions is similar.
