The Secret of Secondary Vocational Mathematics Knowledge

This book is based on the latest "14th Five-Year Plan" national planning textbook for vocational education (public basic course textbook for secondary vocational schools) "Mathematics (Basic Module)" (published in August 2021), combined with actual teaching situations such as higher vocational examinations, to appropriately expand, intersperse, and collect knowledge points. This book uses the form of "open mouth to point out" to explain and point out difficult, error-prone, and skill-rich areas, allowing students to effectively memorize mathematical definitions, theorems, and formulas, and to think and understand by analogy. This book can be used as mathematics class notes or study materials for students in the first, second and third grades of secondary vocational schools. It is a very rare and useful mathematics tutoring book for students who are about to take the higher vocational exams. At the same time, this book can also provide a lesson preparation reference for secondary vocational mathematics teachers.
