In this child's mind, the axe detective is really powerful! As long as he lists a series of mathematical equations, he can solve one crime after another by solving problems. It's really awesome. If only I could be as proficient in mathematics as he is.
When he grew up, the child became a children's book editor. Although his work has nothing to do with mathematics, he is always interested in interesting mathematical problems. One day, the editor got acquainted with an old math professor. The editor was pleasantly surprised to find that this famous math professor and popular science writer turned out to be Professor Li Yupei, the "father" of the detective Axe who was fascinated by him when he was a child.
Professor Li's works not only gave birth to the axe inspector who loves to solve equations and solve crimes, but also gave birth to a large number of lively and lovely characters such as the mathematical monster pig, the mathematical commander Niu Xiaotun and the mathematical monkey. These heroes all have a * * * nature, that is, no one is worried about learning mathematics, they all like mathematics, and they are all masters of mathematics.
Analysis of Li Yupei's Mathematical Stories This book aims at the level of readers' mastery of mathematical knowledge and thinking ability in different classes of primary schools, and selects the contents suitable for reading in the lower, middle and upper grades of primary schools from Professor Li Yupei's most popular mathematical story creation.
Combined with the typical problems and solutions in mathematics learning, this paper summarizes the knowledge points of mathematics, and then matches them with full-color illustrations (pinyin is also noted in lower grades).
