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

Li Zexuan picked a few students casually, 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 would be able to remember the students' names just by listening to their self-introductions, and they couldn't help but be more convinced by this new gentleman.

The five of them honestly came to the blackboard, took out the chalk, and prepared to answer the question as Li Zexuan had just written on the blackboard.

Behold..........

"Smack!"

As soon as the five of them put the chalk on the blackboard, the chalk in their hands broke one after another, and Kong Yingda and Xu Hongzhi who looked at it below were distressed for a while, this thing seemed to them to be a good thing for teaching and educating people.

People who are used to writing with a brush, the first time they use chalk, it is normal to not grasp the strength well, Li Zexuan did not reprimand them, just a few pieces of chalk, he is not distressed.

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

It turned out to be a mixed operation of addition, subtraction, multiplication and division, and the two numbers multiplied by each other were three digits, he only learned this new arithmetic for the first time today, do you want to be so ruthless?

The little fat man puffed out his mouth and glanced at Li Zexuan with resentment, he was sure that Li Zexuan must have done it on purpose.

But how could he Li Tai be a person who casually admits defeat, he gritted his teeth and fought hard.

With a burst of chalk and blackboard rubbing against each other, several people began to answer the question, a moment later, Ke Shiqing, Wang Meng, Meng Wenhao, Zeng Ziran four people finished the calculation, put down the chalk, and returned to their seats.

Only Li Tai was still there sweating profusely calculating, Li Zexuan smiled and didn't go up to stimulate him, first looked at the answers of the other four students, and slowly his smile froze on his face.

"Wang Meng, stand up for me!"

"Uh, first...... Mr! ”

Wang Meng realized that he should have miscalculated, and got up tremblingly and stammered.

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

"Uh, first... Sir, yes.... It's you... You taught.... Yes! ”

Wang Meng said strangely.

Li Zexuan was furious: "Fart, you show me the multiplication table on the blackboard!" See how much nine times six really is! ”

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

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

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

Lying down, Li Zexuan's heart was full of 10,000 alpacas galloping by at the moment.

The other students in the school hall were silent for a moment, and they couldn't help but laugh.

Li Zexuan explained the commutative law of multiplication to Wang Meng, and punished him to copy the multiplication table ten times in front of each other.

This question is actually not difficult, but it will take some time to solve it, Li Tai wiped the sweat on his forehead, put down the chalk, glanced at Li Zexuan hatefully, and turned around to return to his seat.

"Poof! Hahaha! ”

The students pointed to Li Tai's face and laughed, it turned out that when Li Tai had just wiped his sweat, he accidentally wiped the chalk ash on his face, and suddenly he was like a little fat pig who wiped ****.

Li Tai reacted, and hurriedly wiped his face with his sleeve while embarrassingly dodging back to his seat.

Li Zexuan ignored everyone's laughter, he looked at Li Tai's answer, and then couldn't help nodding, although this little fat man is sometimes arrogant, but it is undeniable that people do have arrogant capital, and they learn things faster than others.

"Quiet! What a laugh! ”

Li Zexuan roared, and the students in the teaching hall immediately quieted down.

Li Zexuan nodded with satisfaction, and then said, "Except for Wang Meng, the other four students have all done it right, which is worthy of praise." Especially Li Tai, he had the most difficult question, but he still made it, and everyone applauded him! ”

After speaking, Li Zexuan took the lead in applauding.

But all the students looked at him strangely, and did not applaud, Li Zexuan relieved himself, and suddenly understood something, there seems to be no applause when he praised others in ancient times!

In fact, the origin of applause is said to have been in ancient Rome BC, and among a barbarian tribe that was at war with Rome, there was a custom that when the leader finished speaking or making a call, the soldiers would beat their weapons and make a sound in support of them.

This was of course much easier and more powerful than the Roman soldiers using "shouting" to "respond to the leadership", so that practice was gradually learned by the Roman soldiers, and finally developed into "applause".

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

"Ahem, if a student is praised in the future, we will applaud and congratulate him, this is the tradition that this will remain unchanged in the future, have you heard?"

If there is no such rule, then I will formulate this rule, Li Zexuan thought.

Now Li Zexuan has the absolute right to speak in this class, although the students have doubts in their hearts, no one has raised any objections to this, and they applauded!

"Bang bang bang!"

There was loud applause in the teaching room.

"Hey, hey!"

Li Tai listened to it, and suddenly felt that this kind of feeling of being applauded by others was quite refreshing, and immediately he felt that Li Zexuan was not so hateful, and then he couldn't help but applaud himself!

Kong Yingda and Xu Hongzhi shook their heads and smiled bitterly, looking at all the official and private schools in Datang, how could there be a teacher like Li Zexuan, and the whole school was in chaos.

Li Zexuan saw that the time was almost up, and at noon he also asked Cheng Yanjin, Qin Qiong and others to have dinner in Zuixian Building, so he said:

"Okay, this morning's class is over, in the afternoon you can study by yourself, about your textbooks, I will personally fund them, and arrange craftsmen to print them out for you in the next two days, and then each person will have one copy!"

"Thank you, sir!"

"Thank you, sir!"

All the students were grateful from the bottom of their hearts, although this new gentleman was a little bit of a trick, but he was knowledgeable and generous.

"Poof!"

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 times to buy this textbook! Why can others send it for free without spending money?

"Eh, Brother Qingque, why don't I return the money to you?"

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

Li Tai waved his hand and said depressedly: "No! ”

The money he Li Tai sent out, how can he have the face to come back.

Li Zexuan thought for a while, and then said: "Oh, by the way, there is another question, the question is the ginkgo tree in the west of the gate of Guozijian, how high is the highest place, you can give me the measured answer, or you can write out your measurement method and give it to me."

In any case, you have to turn it in for the next class. If you do the best job in this homework, you can add two points to this month's monthly exam. Tomorrow is the seventh day of the new year, we will not have classes, and the seventh, eighth, fourteenth, fifteenth, twenty-first, twenty-second, twenty-eighth, and twenty-ninth of each month will be closed. Alright, class! ”

After saying that, he was about to go out in style, Li Tai, Lan'er, Tie Dan, Kong Yingda and Xu Hongzhi hurriedly followed.

The rest of the students in the dormitory exploded.

"Huh? The ginkgo tree at the gate of Guozijian is afraid that it is more than ten zhang high, right? How do you measure this? ”

"yes, I'm afraid the longest ruler isn't that long, right?"

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

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

"Isn't that too much? What would the students of other schools think when they found out? ”

(During the Zhenguan period of the Tang Dynasty, officials took a five-day break, and Li Zexuan had eight days off a month, which was really a lot.) ）

"Whatever he thinks? What are we afraid of? ”

"Yes, yes, yes!"

"I said you better think about how to solve the problem left by the gentleman! This question is well written, and the monthly exam will add points! ”

"Haha, don't be afraid, I'll go back and ask my father, my father is the secretary of the Ministry of Industry, maybe he can know!"

"Wang Meng, you are shameless!"

Thank you Dream Sword, and again and again. Thank you for the monthly pass!
