Inside the Arithmetic Museum.

The students sat upright one after another, listening attentively to Li Zexuan's speech, powerful people will be respected wherever they go, Li Zexuan has won everyone's heartfelt respect with his strong arithmetic ability.

"Hehe, students, in my class, if you have any questions during the lecture, you can raise your hand to interrupt me at any time, and we will discuss the problems together. Don't be embarrassed to bury your doubts in your heart, as your questions will accumulate more and more. ”

Li Zexuan saw that they were all sitting with serious expressions and sitting upright, so he couldn't help but say a few words to let them relax.

When the students heard this, they all felt that this way of teaching was very novel, but in the past, Mr. was talking at the top, but they listened silently below, and if they had any questions, they could only hold back to ask Mr. after class.

Li Zexuan continued:

"I don't care how you learned before, since I'm here to teach, you have to listen to me and learn at my pace in the future. In the future, the arithmetic hall has a small exam every seven days, a high school exam every month, a big exam every six months, and the first monthly exam, I will privately fund you to go to the drunken fairy building for free to have a glorious banquet, you can bring your family, and you can order wine and food casually, but you are not allowed to waste it.

The last five in the monthly exam, before the next monthly exam, take turns to clean the hygiene of the arithmetic hall. In two days, I will have people set up a big sign in front of the arithmetic hall, and the top five in the monthly exam will enter the honor list, and the last five will enter the shame list.

As for the first place in the semi-annual exam, the reward will be 100 times. Did you all hear me clearly? ”

The students in the hall were still applauding Li Zexuan's enlightened class system just now, when they heard this series of rewards and punishments, they were dumbfounded.

"Huh? The bottom five not only have to clean up, but also enter the shame list? ”

"That's a shame, no, you can't say anything and be the last five, you have to fight at night in the future."

"The first place can go to the Drunken Immortal Building to eat for free, how much is this worth!"

"Wen Hao, do you want to fight for the first place?"

"Well, I will definitely fight for it, I once told my father and mother that I will definitely take them to the best restaurant in Chang'an to eat one day!"

"Okay, brother, I believe you can do it!"

"Brother Shiqing, isn't this first place in your bag!"

"Don't say that, none of us understand Mr.'s new arithmetic, our starting point is the same, oh, if you want to say that the most likely to win the first place is Mr.'s personal disciple Tie Dan!"

"Well, it's possible, but isn't it fair like this!"

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

Kong Yingda was silent on the side, in fact, he was secretly thinking in his heart: This reward and punishment system is novel, look back and see how effective it is, if it can promote students' learning, then it will be promoted to other schools in Guozijian.

The reactions of these students were all expected by Li Zexuan, after all, no one wanted to be embarrassed, and when they were quieter, Li Zexuan picked up a piece of chalk, squinted his eyes and smiled:

"Don't worry, if Tie Dan ranks first, then the first place reward of the month will be automatically postponed to the second place. Okay, the learning system of the arithmetic hall is almost the same as what you explained, and then let's get to know each other first, according to the order of sitting, each person stands up and introduces himself, come, start with you. ”

A thin boy in the first row near the door, when he saw Li Zexuan pointing at him, his face instantly turned red, and he snorted: "Sir, is Mr. calling me?" ”

Li Zexuan also saw that the child was a little shy, but the root cause of his shyness was still not confident, he smiled mildly and encouraged: "Yes, start with you, don't be afraid, I don't care what the relationship between teachers and students was before the Arithmetic Academy, but from today onwards, all of us in the Arithmetic Pavilion are a family, and teachers and students must love each other and help each other. ”

The boy hesitated for a while, and finally mustered up the courage to stand up, and said a little shyly: "Hello sir, hello classmates, I am Liu Yan, from Jinju, Hedong Province. ”

Li Zexuan is a stumbling person, this name is so "domineering"!

"Hello sir, good classmates, I'm **** Yu, from Jizhou, Hebei Province."

………

Li Zexuan listened carefully to their self-introductions, remembering their names and faces one by one, his memory was excellent, and after the students had all introduced themselves, he had already built a database of the information of these students in his heart.

"Okay, let's start the class, I'll teach you a new way of counting in this first class, you look at these ten numbers on the blackboard........."

Li Zexuan was writing and drawing on the blackboard while introducing the Arabic numerals to the students.

The students were all watching and listening attentively, and taking notes below, Kong Yingda nodded secretly when he saw this, this way of teaching on the blackboard can indeed make it easier for students to concentrate.

………

"Hey, Sister Lan'er, can you give me your teaching materials? I could buy it for 10 dollars! ”

Look, our Royal Highness the King of Wei is generous, and he comes up directly to be ten times, unlike Li Chengqian's poor man before, who asked Lan'er to buy a copy of "Journey to the West", gritting his teeth and snorting for a long time before he was willing to go out five times.

It turned out that Li Tai saw that the rest of the people were bowing their heads and taking notes from time to time, but Lan'er and Tie Dan didn't take notes, he glanced at their tables, and immediately discovered the secret, it turned out that these two people had teaching materials. So he rolled his eyes, then leaned next to Lan'er and whispered.

Who is the king of Wei, and it is not a problem if he can solve it with money. But Lan'er herself is a little rich woman, so she is not rare for this money.

"If you don't sell it, you're still the king of Wei, it's so stingy!"

Lan'er pouted and said with a look of disdain.

"Poof~"

The iron egg next to him hurriedly covered his mouth and stifled the laughter that came to his lips.

Li Tai's face is full of black lines, looking at the civil and military affairs of the Manchu Dynasty, dare to say that he Li Tai is stingy, I'm afraid that there is only Lan'er, the girl, right?

"Twenty times!"

Li Tai said ruthlessly. He didn't believe that this girl was not moved by so much money.

Unfortunately, the result still disappointed him.

"Not for sale!"

Li Tai's face darkened, and he wanted to be angry, but when he saw Li Zexuan who was lecturing above, he was a little angry and didn't dare to speak, so he had to lean next to Tie Dan and said, "Brother Tie Dan, how about you sell your teaching materials to Brother Wei?" ”

Tie Dan thought about it and felt that it was quite cost-effective to sell a book for twenty times, besides, he heard from the master yesterday that this textbook ......

So he nodded to Li Tai and said, "Yes!" ”

With that, he handed the book to Li Tai.

Li Tai was overjoyed, after he was rejected by Lan'er, he didn't have much hope, but he didn't expect to have an unexpected joy, he took the textbook excitedly, without saying a word, took out a few gold cakes, put them on the table of iron eggs, and said with a smile:

"Okay, Tie Dan, you are righteous enough, my brother Li Tai has accepted it!"

Tie Dan took the golden cake, and secretly rejoiced in his heart, with so much money, he could buy a lot of delicious food for his father and sister to take back!

………

"The new notation, the new notation, and the four algorithms I have explained to you clearly, the following is the multiplication table, you copy it down, you must memorize it today, and I will check it tomorrow!"

Li Zexuan wrote the multiplication table on the blackboard and said to the students.

While copying, the students lamented how easy it was to use the new numbers and operators, many times more convenient than the previous use of Chinese characters. Xu Hongzhi next to him couldn't help but praise Kong Yingda: "Kong Sacrifice Wine, Dr. Li's advantages of this new notation method and new operation symbols are so obvious, it can be called a groundbreaking change in the history of arithmetic." ”

Although Kong Yingda is not specialized in arithmetic, he also has some research on arithmetic, and he nodded and agreed: "That's true, I'm afraid your arithmetic hall will officially rise in the future!" ”

After a while, after they all finished copying, Li Zexuan casually came up with five addition, subtraction, multiplication and division problems on the blackboard, and said: "Now, you can use the knowledge I just told you to solve these five problems, and I will ask five people to come up and do them on the blackboard." ”
