Otaku Engineer in Great Tang Dynasty

"Ke Shiqing, Wang Meng, Meng Wenhao, Zeng Ziran, Li Tai, five of you come up and do these five questions in the order in which I call them."

Li Zexuan randomly selected a few students, of course Li Tai was an exception. He wanted to deliberately embarrass this little fat man.

Wang Meng, Meng Wenhao, and Zeng Ziran were shocked. They didn't expect that Li Zexuan could remember their names after just listening to the students' self-introduction, and couldn't help being more convinced by the new gentleman.

The five people honestly came to the front of the blackboard, drew out the chalk, and learned how Li Zexuan had just written on the blackboard, ready to answer questions.

Who knows..........

"Patter!"

As soon as the five people clicked on the chalk on the blackboard, the chalk in their hands broke off one after another. Kong Yingda and Xu Hongzhi below were distressed for a while. In their opinion, this thing is a good thing for teaching and educating people.

Those who are accustomed to writing with a brush used chalk for the first time. It is normal for them not to grasp the strength. Li Zexuan did not reprimand them, just a few pieces of chalk, and he did not feel distressed.

Li Tai frowned, he tried a few more times, and finally got used to the strength of the chalk, and when he looked at the question carefully, he was instantly dumbfounded!

It turned out to be a mixed operation of addition, subtraction, multiplication and division, and the two numbers that are multiplied by each other are three digits. He is only learning this new mathematical formula for the first time today. Should it be so cruel?

The little fat man bulged his mouth and glanced at Li Zexuan with a rather murmur, he was sure that Li Zexuan must be deliberate.

But Li Tai is a casual surrender, he gritted his teeth and fought hard.

Accompanied by a squeak of chalk rubbing against the blackboard, several people began to answer the questions. After a while, Ke Shiqing, Wang Meng, Meng Wenhao, and Zeng Ziran finished their calculations, put down the chalk, and returned to their seats.

Only Li Tai was still there with sweating calculations. Li Zexuan smiled and did not go up to irritate him. First, he looked at the answers of the other four students, and his smile slowly solidified on his face.

"Wang Meng, stand up for me!"

"Uh, first... sir!"

Wang Meng realized that he should be wrong, and stood up tremblingly.

"Who taught you that nine times six is ​​forty-five?"

"Uh, first...sir, yes...you...you taught...ah!"

Wang Meng said strangely.

Li Zexuan was furious: "Fart, show me the multiplication table on the blackboard! See how much nine times six is ​​equal to!"

Wang Meng looked at the multiplication table and felt that he had not done what he had written, and he immediately gained confidence, so he said confidently:

"Teacher, look at the sixty nine fifty-four written on the multiplication table, isn't ninety six equal to forty-five?"

.........

Fuck, Li Zexuan had 10,000 alpacas rushing past.

The other students in the teaching house were silent for a moment, and couldn't help laughing.

Li Zexuan explained the commutative law of multiplication to Wang Meng, who was a tiger-headed tiger-brained, and punished him to copy the multiplication table ten times from the front to the back. At this time, Li Tai finally finished his problem, and he wrote more than 20 lines of calculation steps. , It really embarrassed him.

This question is actually not difficult. It just takes some time to solve it. Li Tai wiped the sweat from his forehead, put down the chalk, gave Li Zexuan a bitter look, and turned around to go back to his seat.

"Puff! Hahaha!"

The students pointed at Li Tai's face and laughed. It turned out that when Li Tai just wiped his sweat, he accidentally wiped the chalk dust on his face, just like a little fat pig that wiped it off.

Li Tai reacted, wiping his face quickly with his sleeve, and flashed back to his seat awkwardly.

Li Zexuan ignored the laughter of everyone. He looked at the answer that Li Tai solved, and then nodded. Although this little fat man is sometimes arrogant, it is undeniable that he does have arrogant capital, and learning things is better than others. fast.

"Quiet! What a laugh!"

Li Zexuan roared, and the students in the teaching house immediately became quiet.

Li Zexuan nodded with satisfaction, and then said, "Except for Wang Meng, all the other four students did the right thing. It is worthy of praise. Especially Li Tai, he has the most difficult question, but he did it. Everyone applauded him. !"

After speaking, Li Zexuan took the lead and clapped his hands.

But all the students looked at him strangely, and did not applaud. Li Zexuan slowed down and immediately understood something. The ancient times praised others as if they did not applaud!

In fact, the origin of applause is said to be in ancient Rome before the Christian era. In a barbaric race that fought with Rome, there was a habit that when the leader had finished speaking or issued a call, the soldiers would knock on their weapons. , Making a sound to show support.

This is of course much easier and more powerful than Roman soldiers using "scream" to "respond to the leadership". Therefore, the practice was gradually learned by Roman soldiers, and finally evolved into "applause."

In ancient China, there is also "applause", but it is not to express welcome and praise, but to express happiness or anger-there is an idiom to clap the palm and laugh as evidence.

"Ahem, which student will be praised in the future, we will applaud and congratulate him together. This is a tradition that we will keep unchanged in the future, have you heard it all?"

Without this rule, I will formulate this rule, as Li Zexuan thought.

Now Li Zexuan has the absolute right to speak in this class. Although the students are puzzled, no one raises objections to this and applauds!

"Papa Papa!"

There was a loud applause in the teaching house.

"Hey!"

As Li Tai listened, he suddenly felt that the taste of being applauded by others was quite refreshing, and suddenly he felt that Li Zexuan was not that hateful, and then he couldn't help applauding himself!

Kong Yingda and Xu Hongzhi shook their heads and smiled bitterly. Looking at all the private schools in Datang, there is no such thing as Li Zexuan's teaching, the whole school is noisy.

Li Zexuan saw that the time was almost up, and at noon also arranged an appointment with Cheng Yaojin, Qin Qiong and others to eat in Zuixianlou, and said:

"Well, this is the end of this morning's course. In the afternoon, you will study by yourself. I will personally fund your textbooks. I will arrange craftsmen to print and distribute them for you in the past two days. You will have one copy for each person at that time!"

"Thank you sir!"

"Thank you sir!"

All the students were grateful from the bottom of their hearts. Although the new gentleman was a bit tricky, he was knowledgeable and generous.

"puff!"

But there is one person who doesn't think so, that is Li Tai, he almost vomited blood when he heard Li Zexuan's words, but it took him twenty quins to buy this textbook! Why can others send it for free without spending money?

"Um, Brother Qingque, should I return the money to you?"

Seeing Li Tai's face depressed, Tie Dan couldn't help but asked tentatively.

Li Tai waved his hand and said depressed: "No need!"

The money he sent out by Li Tai, there is no face to come back.

Li Zexuan thought for a while and said: "Oh~www.ltnovel.com~ By the way, there is another question. The question is the ginkgo tree west of the gate of the Imperial College. How high is the highest place? You can hand in the measured answer. Give it to me, or you can write down your measurement method and give it to me.

In any case, the next class must be handed in. For the best homework this time, you can get two points for this month's exam. Tomorrow is the seventh day of the day and we will not have classes. From now on, the school will be closed on the seventh, eighth, fourteenth, fifteenth, twenty-first, twenty-second, twenty-eight, and twenty-ninth day of every month. Okay, get out of class is over! "

After saying that he was about to go out smartly, Li Tai, Lan'er, Tiedan, Kong Yingda and Xu Hongzhi hurriedly followed out.

The rest of the students in the teaching house exploded.

"Ah? The ginkgo tree at the gate of the Imperial College is probably more than ten feet tall, right? How can this be measured?"

"Yes, the longest ruler is not that long, right?"

"I can't go up even if it's that long!"

"According to what Mr. just said, we can take eight days off every month!"

"Will this be too much? What do students from other colleges think if they know it?"

"What does he think? Why are we afraid of having a husband?"

"Yes, it is extremely!"

"I said you should think hard about how to solve the question left by your husband! This question is written well, but the monthly exam will add points!"

"Haha, I'm not afraid, I'll go back and ask my father, my father is the secretary of the Ministry of Industry, he might know!"

"Wang Meng, you are shameless!"
