The math expert in our class, the cow in our class, wrote 8 words.

The math expert in our class is Liang Jinyu. He has a square face, big eyes and thick black hair. Don't think that he is so handsome, just because he is a big embroidered pillow, and his mathematical and logical ability is extraordinary, which means that Zhuge Liang is alive. No matter what the problem is, he only needs to count it with his fingers, and the answer will jump to the paper.

I remember that once again, the math teacher called us top math students together in our spare time, except for an Olympic math problem that seemed easier to do than to do. I saw that when everyone was immersed in calculation, Liang Jinyu had already given the answer to the teacher, and it was right. But I was still calculating over and over again, and I couldn't figure it out. Finally, he nudged me, and I understood the meaning. It is because of this that I have to admire him.

I remember another time, the teacher didn't know where he got a comprehensive test paper, and suddenly there was a surprise inspection, and the students were at a loss. Some people even covered their heads and shouted, "My God, what should I do?" Some people saw that there was an exam, and immediately turned over the math book and read the general concept; There are also mumu ones, which are amazing. Liang Jinyu was the only one who was very calm and said, "Isn't it just a surprise exam? There's no need to make such a fuss?" The teacher said loudly, "Write quickly and stop talking, or you will receive the test paper." As soon as the students heard it, the classroom was silent, and even the breathing could be heard. I looked at the dense test questions, and the more I wrote, the more annoying I became. The more I wrote, the less I had a clue, and I couldn't help sweating on my head. I looked around, and my classmates were all working hard. When I saw their faces, I knew that none of them could. I took another look at Liang Jinyu, who looked like a leisurely man. When I saw his test paper, I almost finished it. "Rinrin Bell" students' most annoying voice appeared during the exam. In desperation, we had to hand in the papers. In the afternoon math class, the test paper has been handed out. Needless to say, I didn't do well in the exam. I glanced at Liang Jinyu's test paper, and I was shocked. He actually got a perfect score. How dazzling that score was. Alas, this time I, a once-arrogant mathematical genius, finally knew what it meant to be behind the scenes, and there was someone outside. After class, many students asked Liang Jinyu, "Liang Jinyu, how did you do so well in the exam? Did you cheat? Tell me quickly!" Liang Jinyu said with a smile, "How dare I? Those questions I have done after class are very simple." In this way, I admire him deeply.

This is the math expert in our class, a smart and studious person.
