In this winter vacation, I not only read many domestic and foreign literary works, expanded my extracurricular knowledge of Chinese, but also read several extracurricular books on mathematics. In the past, I always felt that there was nothing to read in math extracurricular books, just doing topics. After reading the math brain training camp, I found that math extracurricular books are far more interesting than I expected.

In "Mathematical Mind Training Camp", I remember the most firm question: "Suppose a normal newspaper has 60 pages, but 24 pages and 4 1 pages are all missed, which pages will be missed?" This problem is the first problem I met when I first started reading this book. This question stumped me at that time. Because at that time, I used the method of finding a way and found that I couldn't do it. Later, it was discovered that the newspaper was two pages before and after. If you lose half, the other half will also be lost. This is the way to solve this problem. This question tests the combination of mathematical thinking and common sense of life, which makes me feel very novel.

By reading this book, I have new ideas and really benefited a lot.
