Prophecy

This is a popular mathematics book written for young readers. Its title, Prophecy, comes from a mathematical story in the book that uses a "prophecy" as its starting point: through plots full of suspense and reasoning, the author weaves foundational mathematical ideas—number theory, sequences, equations, geometry, and logical deduction—into the story, so that young readers naturally encounter and understand mathematical principles as they follow the plot and explore whether the prophecy comes true. The book continues author Li Yupei's signature style of teaching knowledge through stories and carrying reasoning forward through suspense; the language is accessible and lively, supported by necessary diagrams and formula explanations, which lowers the threshold for understanding abstract mathematics. The author has long been engaged in writing popular mathematics and is skilled at turning dry formulas and theorems into highly readable narratives, enabling readers to build number sense and exercise logical thinking and reasoning imagination through relaxed reading. The book is suitable for extracurricular reading by students from the upper primary grades through junior secondary school, and can also serve as supplementary material for parents and teachers in mathematics enlightenment and thinking training. It should be noted that the specific chapter structure and plot details of this book are subject to the actual publication; this page provides only a general introduction based on the title and reliable sources, and does not fabricate specific chapter content.
