One day, on the way to the Olympic math class, I said to my mother, "I used to think the Olympic math problem was difficult, but it was beyond the understanding of ordinary people, but now I think the Olympic math is actually very simple, as long as I know the method." Do you know why? Because I am full of interest in Olympic Mathematics, I am particularly excited in every class. Like Chinese books, the distributed Olympic books are divided into several modules, and I also have likes and dislikes. My favorite module is digital puzzle. I used to think it was difficult for fans of every number. Now we know, in fact, as long as we grasp the characteristics and know the methods, we will magically feel that some topics are simply a piece of cake. For example, we can find four breakthroughs, such as: first, finally, carry and abdicate. With these, we won't be afraid of difficult problems.

One day, when I came home from an Olympic math class, I sat on the sofa and tested my father with a number puzzle. It took dad a long time to figure it out. I told him that two numbers can only add up to one, three numbers can only add up to two, and so on. If you find a breakthrough in the first or last place, the problem can be solved! Dad shouted: "The Olympics is really great!" Now I am my father's little teacher again! How interesting mathematics is! As long as you find its breakthrough and master its main points, some topics will become magical and interesting, a piece of cake!
