"Uh, Ugly Niu and Huaiyu, are you two here?"

When he came to the school, he saw Qin Huaiyu, who was tall and horse, Dacheng Chumo and gentle, and Li Zexuan remembered that the old generals such as Cheng Yaojin entrusted their son to the School of Mathematics, but he did not expect these generals. The second generation came today.

Cheng Chumo lowered his head and said weakly:

"Brother, I don't want to come, but my father said that if I don't come, I will break my legs. I thought he was trying to frighten me. Who knew that he actually came this morning, and my mother couldn't hold it back. Fortunately, brother, I ran fast, otherwise I should be lying in the Imperial Physician's Office now. Oh, Xiaoxuan, we used to be brothers, but now you suddenly became my teacher for no reason. what!"

Hearing Cheng Lumo's complaint, Li Zexuan almost didn't laugh out loud. He really didn't expect Cheng Yaojin to be so cruel to his son.

He was about to say something to comfort him when Qin Huaiyu on the side said with a smile: "Ugly cow, Uncle Cheng is also doing it for your own good. Since you are here, you should study hard. Besides, I just borrowed notes from other classmates. , and found that Xiaoxuan's new arithmetic does have many merits......"

"Stop, stop, Huaiyu, don't talk about it, you have good grades, of course you don't care, but look at my old Cheng, how can I look like a scholar! I just heard that this counts as the last five students in the monthly exam of the school to be cleaned. Schoolhouse, what kind of shame list do you want to enter, I really don’t know which turtle son came up with a bad idea, but it will kill me Lao Cheng!”

Cheng Chumo didn't wait for Qin Huaiyu to finish speaking, and then interrupted directly. He spoke in such a loud voice that 80% of the people in the classroom heard it. The noisy classroom fell silent in an instant. Except for the three newcomers Cheng Lumo, all the other students looked at this man who dared to speak madly. God man.

Li Zexuan's old face darkened, and he kicked at Cheng Chumo's thigh, "Slot, I came up with this idea. If you get into the last five in the exam this month, you will clean my schoolhouse for two months!"

Cheng Chumo was kicked and staggered, and after listening to Li Zexuan's words, he widened his eyes, looked bewildered, stretched out his hand and said, "Hey, Xiaoxuan, don't! What's the relationship between our brothers? Is it like this? Just treat me like a fart!"

"Hahaha!"

The students couldn't help laughing when they saw Cheng Lumo playing tricks. Many of them knew the identities of Cheng Chumo's people. After asking them privately, they all knew. They thought that these second-generation generals were very proud, but they didn't expect Cheng Chumo to be so funny. Than, they are no different from ordinary people like them.

Li Zexuan ignored Cheng Chumo, looked at the dark and fat boy next to Qin Huaiyu, and asked, "Are you Yuchi Baolin?"

The little chubby scratched his head and said with a laugh, "Well, I'm Yuchi Baolin, so just call me Baolin!"

Li Zexuan nodded and encouraged: "Okay, Paulin, you should study hard. If you don't understand anything, you can ask Tie Dan, or you can ask me directly."

Cheng Chumo muttered to the side: "Che, what does he have to learn, in the end he is not going to grab the last one with me!"

Li Zexuan was so angry that he slapped him on the head in return, "If you're really the last one in the exam, then I'll see how Uncle Cheng treats you, and I don't recognize you as a shameful brother!"

Cheng Chumo rubbed his head, looking at him aggrievedly like an angry little daughter-in-law, and muttered, "Xiao Xuan, you are not being kind! Brother, I usually treat you so well, how can you do this?"

"What's the matter? Even the king has to do what he wants here, what do you want, ugly cow?"

This guy, Li Tai, just came to the school today. As soon as he came in, he heard Cheng Chumo's grievances and couldn't help but interject.

Cheng Chumo looked at Li Tai in surprise, opened his mouth, and wanted to say something, but in the end he didn't say anything. He put his hand on his forehead and sighed.

"Okay, let's start the class! Students, take out your homework, damn you, take it to me!"

A few bells and drums could be heard outside. Li Zexuan hired a watchman to ring the "school bell" for the School of Mathematics. Hearing the class bell rang, Li Zexuan started a new day of classes.

"Yes, Master!"

Tie Dan stood up and collected his homework one by one. When he came in the morning, he had just distributed new books to all the students one by one. In addition, he was Li Zexuan's direct disciple, so the students treated him very well.

After a while, Li Zexuan took everyone's homework and looked at it at a glance. After a while, he frowned and shouted, "Wang Meng, get up for me!"

Wang Meng sat down and waited for Li Zexuan to praise him. His homework was something he thought about for a long time, but listening to Li Zexuan's current tone, it was obvious that he was not trying to praise him.

Wang Meng stood up in astonishment and stammered, "First... sir!"

"Tell everyone, what method did you write in your homework?"

Wang Mengnahan said: "Uh, I... I wrote that the ginkgo tree was sawed down, and then measured with a few rulers on the ground to get the height of the ginkgo tree!"

"Hahaha"

The students burst into laughter after hearing this.

Cheng Chumo was also happy, he laughed and shouted: "Haha, brother Wang Meng, with you here, it seems that my old Cheng doesn't need to be last in the exam, haha!"

Li Zexuan asked everyone to be quiet, looked at Wang Meng and said, "Now you know yourself

is it wrong? I teach you math, so that you can apply what you have learned to your life, instead of letting you rely on brute force for everything like before! "

Wang Meng hesitated for a while, and said unconvinced: "But my father said that when he was doing woodworking, he used this method to measure the length of tree trunks!"

Li Zexuan: ......

..........................................

After writing with Wang Meng for a long time, he finally convinced this one-strand thing. Li Zexuan began to evaluate the winners of this assignment. All the students were shocked and listened carefully.

"After careful consideration, Meng Wenhao did the best job this time. His method was to measure the length of the shadows of people and trees at the same time, and multiply the length of the shadows by the shadows and the actual height of the human body. The ratio of the actual length of the ginkgo tree is obtained.

In addition to Meng Wenhao, Li Tai's method is also very good. He makes people's eyes close to the ground, and then moves a market ruler until the top of the market ruler is on the same line with the human eye and the tree tip. The ratio of the distance to the human eye to the distance from the market ruler to the human eye, and multiplying the length of the market ruler to get the true height of the ginkgo tree.

The method of the two of them is the smartest and the best, but in comparison, I think Meng Wenhao's method is simpler and more accurate, and he deserves the first place. Let's give applause to these two students! "
