Kiki came to my house to play this afternoon, and we were busy, so I took out the Olympic math book of the special training class to teach Kiki knowledge.

Since the start of the special training class for top students, the teacher has talked for five class hours. Every day when I go home, I will consolidate the courses taught by the teacher and ask questions if I don't understand. In this way, I am not only more and more interested in Olympic Mathematics, but also the efficiency of doing problems is obviously improved.

I asked Kiki, "Do you want to hear me talk about the Olympiad?" Kiki nodded and saw her thirsty eyes, and I agreed. Find out the small blackboard. I am like a little teacher, holding chalk in my hand and starting class. First of all, I gave Kiki a problem to solve the equation and asked her to try. After reading it for a long time, she finally picked up the chalk and wrote. The answer is right, but it's a stupid method, so I explained it to her in the way my teacher taught me. Because what I said is not as interesting as what the teacher said, Kiki sounds a little hard, but she is very serious. She tried her best to understand every question.

What I told Kiki was the most representative example of each unit, which was a little difficult, but the seemingly complicated problem was solved immediately by using the knowledge of Olympic Mathematics. Kiki suddenly realized after listening to my explanation, but there is a trip problem, which is more difficult in the example. I told it twice, but Kiki was still at a loss. When I spoke for the third time, I became more and more impatient and Kiki became more and more confused, but Kiki was patient. Seeing her unhurried expression, I calmed down and an invisible admiration arose. In this way, I spoke patiently, she listened carefully, and Kiki finally understood. It is getting late. Kiki, it's time to go home. Before leaving, she said to me, "I'll listen to you tell me about the Olympic Games next time."

Confucius said: A threesome must have a teacher. In this process of talking about Olympic Mathematics, Kiki learned a lot of knowledge, and I also learned the truth of being a man.
