Looking for Books for Junior High School Study! ! (Over)
My grades started plummeting when I entered junior high school. I obviously learned and knew how to do most of the questions correctly, but I got them wrong when I took the test. Now I am in high school! In the end, I did okay in the exam. Thank you everyone for reading the book (although I didn't read it either). I'll just treat this post as a souvenir.

I especially like the introduction in the book about primitive calculation tools, such as knotting notes and the abacus, as well as the mathematical applications in agricultural production of the ancient Egyptians. The author Wang Hailin's explanations are very vivid, making complex mathematical knowledge simple and easy to understand. This book not only increased my knowledge, but also made me more interested in mathematics. Recommended to friends who are interested in mathematics!
