The vision of cultivating excellent competition new methods and elite mathematics, what is the difference between the classic of Olympic Mathematics and the problem-solving manual of junior high school mathematics competition, and who is difficult (grade three) Is it Huang Dongpo's? I bought them all in junior high school. The topics of elite mathematics are more difficult, and most of them are competition topics, such as the national junior high school mathematics league champion and the Olympic champion in other regions. What I value most is that there are many theorems in it, which seem difficult, but they are not, such as Seva theorem and Stewart theorem. There are still many, if the landlord has a competitive hobby, he may wish to prove it. The difficulty is four and a half stars. The book is divided into two parts, and examples are analyzed and dissected. New methods and new ideas suggest that upstream students buy them, mainly middle school examination questions and competition questions, which are divided into three parts. The example difficulty is 4 stars, the basic training difficulty is 3 stars, and the innovative thinking is 3 and a half stars. It is intended to let students master some mathematical methods such as the combination of numbers and shapes and adding common auxiliary lines, which is not as difficult as a big vision. I only read the last two books, but I haven't done them systematically. They are all real Olympic series, and the difficulty is almost the same as the big vision. The landlord can buy new methods first, and then buy a big vision and problem-solving manual when he is proficient, so as to be familiar with the Olympics, otherwise he will skip buying Olympic classics directly, and it will be very difficult for the landlord to do it. I also like doing Olympic games questions. The landlord wishes you success in your studies.

The strongest science group will answer your questions and hope to adopt them.
