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 has excellent mathematical and logical ability, it means that Zhuge Liang is alive. No matter what the question is, he just needs to count it by hand and the answer will jump to paper.

I remember once, the math teacher called us top math students together in our spare time, except for an Olympic math problem that looked easier to do than to do. I saw that when everyone was immersed in the calculation, Liang Jinyu had given the answer to the teacher, and it was right. But I still calculate over and over again, and I can't figure it out. Finally, he gave me a gentle push, and I understood the meaning. Because of this, I have to admire him.

I remember another time, the teacher didn't know where to get a comprehensive test paper, and suddenly there was a surprise inspection. The students were at a loss, and some even covered their heads and shouted, "My God, what should I do?" Some people see that there is an exam, and immediately turn to the math book to see the general concept; Mu Mu's, too. Great. Liang Jinyu is the only person who is very calm. He said, "Isn't this just a surprise exam? There is no need to make such a fuss, is there? " The teacher said loudly, "Write quickly, stop talking, or you will close the paper." As soon as the students listened, the classroom was silent, and even breathing could be heard. I looked at the dense test questions, and the more I wrote, the more annoying I became, and the less I had a clue. I can't help sweating. I looked around and my classmates were all working hard. When I saw their faces, I knew none of them could do it. I looked at Liang Jinyu again. He looked like a laid-back man. On his test paper, he has almost finished it. The most annoying voice of "Rinrin Bell" students appears during the exam. In desperation, we had to hand in our papers. In math class this afternoon, 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 got full marks. How dazzling that score is. Alas, this time I, a once arrogant mathematical genius, finally knew what it meant to be someone behind the scenes and 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 smiled and said, "How dare I? The questions I have done after class are very simple. " In this way, I deeply admire him.

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