In the arithmetic library.
The students sat upright and listened attentively to Li Zexuan's speech. A capable person will be respected wherever he goes. Li Zexuan has gained the heartfelt respect of everyone with his strong arithmetic ability.
"Haha, students, in my class, if you have any questions during the lecture, you can raise your hands to interrupt me at any time. If you have any questions, we can discuss them together. Don't bury your doubts in your heart because of embarrassment. Then your problems will pile up.”
When Li Zexuan saw them all looking serious and sitting upright, he couldn't help but say a few words to let them relax.
When the students heard this, they all felt that this teaching method was very novel. In the past, the teacher would speak from above, and they would listen silently from below. If they had any questions, they could only hold back and ask the teacher after class.
Li Zexuan continued:
"I don't care how you studied in the past. Since I'm here to teach, you must listen to me and study at my pace from now on. From now on, in the math school, there will be a small test every seven days, a high school test every month, and a big test every six months. , if you are first in the monthly exam, I will personally fund it and reward you with a free glorious banquet at Zuixian Tower. You can bring your family, and you can order whatever food you want, but don't waste it.
The top five students in the monthly exam will take turns cleaning the math school before the next monthly exam. In two days I will have someone put up a big sign in front of the math school. The top five in the monthly exam will be on the honor list, and the bottom five will be on the shame list.
As for the first place in the half-year exam, the reward will be one hundred guan. Did you all hear that clearly? "
The students in the hall had just been applauding Li Zexuan's enlightened class system, but now they were dumbfounded when they heard this series of reward and punishment systems.
"Huh? The bottom five will not only clean the house, but also be on the list of shame?"
"That's so embarrassing. No, no matter what, you can't be among the last five. From now on, you have to burn the midnight oil and fight at night."
"The first place can go to Zuixian Tower for a free meal. How much is that worth!"
"Wen Hao, do you want to strive for first place?"
"Well, I will definitely fight for it. I once told my parents that one day I will take them to the best restaurant in Chang'an for dinner!"
"Okay, brother, I believe you can do it!"
"Brother Shiqing, isn't this first place yours?"
"You must not say that. None of us understand Sir's new arithmetic. We all have the same starting point. Well, the one who is most likely to win the first place is probably Mr. Tiedan, his direct disciple!"
"Well, this is possible, but isn't it unfair?"
... ... ... ... ... ...
Kong Yingda was wiping his beard and saying nothing. In fact, he was thinking to himself: This reward and punishment system is quite novel. Let’s look back and see how effective it is. If it can promote students’ learning, then it can be extended to other schools in the Imperial College.
The reaction of these students was within Li Zexuan's expectation. After all, no one wanted to be embarrassed. After they became quieter, Li Zexuan picked up a piece of chalk, squinted his eyes and said with a smile:
"Don't worry, everyone, if Tiedan ranks first, then the reward for the first place of the month will automatically be extended to the second place. Okay, the learning system of the Mathematical Academy is pretty much what you explained, let's get to know each other first. , in order of seating, everyone stands up and introduces himself, come on, let’s start with you.”
A thin boy in the first row near the door saw Li Zexuan pointing at him. His face instantly turned red and he murmured: "Sir, are you calling me?"
Li Zexuan also saw that the child was a little shy, but the root cause of shyness was lack of confidence. He smiled gently and encouraged: "Yes, let's start with you. Don't be afraid. I don't care what the teacher-student relationship was like before, but from today on To begin with, all of us in the School of Mathematical Sciences are a family, and teachers and students must love each other and help each other. Since we are a family, why don’t you dare to get up and introduce yourself?”
The boy hesitated for a while, then finally plucked up the courage to stand up and said a little shyly: "Hello, sir, hello classmates, I am Liu Yan, from Jinzhou, Hedong Road."
Li Zexuan staggered, this name is so "overbearing"!
"Hello sir, hello classmates, I am **** Yu, from Jizhou, Hebei Province."
… …
Li Zexuan listened carefully to their self-introductions and remembered their names and faces one by one. He has an excellent memory. After all the students introduced themselves, he had already constructed the information about these students in his mind. a database.
"Okay, let's start the class. In this first class, I will teach you a new counting method. Look at the ten numbers on the blackboard..."
Li Zexuan introduced the Arabic numerals to the students while writing and drawing on the blackboard.
The students were watching and listening attentively, and taking notes below. Kong Yingda nodded secretly when he saw this. This method of teaching with a blackboard can indeed make it easier for students to concentrate.
… …
"Hey, sister Lan'er, can you give me your teaching materials? I can buy them for ten dollars!"
Look, our Royal Highness the King of Wei is very generous with his money, and he will give ten strings directly, unlike the poor guy Li Chengqian who asked Lan'er to buy a copy of "Journey to the West", and gritted his teeth for a long time before he was willing to give five strings.
It turned out that Li Tai saw that the others were lowering their heads to take notes from time to time, except Lan'er and Tiedan. He glanced at their desks and immediately discovered the secret. It turned out that these two people had teaching materials. So he rolled his eyes, moved next to Lan'er, and whispered.
Who is King Wei? It's no big deal if he can solve it with money. But Lan'er is a little rich woman herself, so she doesn't care about this little money.
"If you don't sell it, you will still be the King of Wei. You are so stingy!"
Lan'er pouted and said with disdain.
"Pfft~"
Tiedan next to him quickly covered his mouth to stifle the laughter on his lips.
Li Tai's face is full of black lines. Looking at the civil and military officials of the court, I dare to say that he, Li Tai, is stingy. I'm afraid Lan'er is the only girl, right
"Twenty strings!"
Li Tai said cruelly. He couldn't believe that this girl was not tempted by so much money.
Unfortunately, the result still disappointed him.
"Not for sale!"
Li Tai's face darkened. He wanted to get angry but when he saw Li Zexuan who was giving a lecture above, he was a little too angry to speak. He had to go to Tiedan and said, "Brother Tiedan, sell your teaching materials to me." How about brother?"
Tiedan thought for a while and felt that selling a book for twenty guan was quite a bargain. Besides, he heard his master say yesterday that this textbook...
So he nodded to Li Tai and said, "Okay!"
After saying that, he handed the book to Li Tai.
Li Tai was overjoyed. After being rejected by Lan'er, he didn't have much hope at first. Unexpectedly, he was unexpectedly happy. He took the textbook excitedly, took out a few gold cakes without saying a word, and put them on the iron egg. On the table, he smiled and said:
"Okay, Tiedan, you are so loyal, I, Li Tai, will recognize you as my brother!"
Tiedan took the golden pancake and was secretly happy. With so much money, he could buy a lot of delicious food for his father and sister to take back!
… …
"I have explained the new counting method, the new operation symbols, and the four arithmetic rules to you clearly. The following is the multiplication table. You can copy it down. You must memorize it today. 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 new operators. It was countless times more convenient than using Chinese characters before. Xu Hongzhi, who was standing next to him, couldn't help but praise Kong Yingda: "Kong Jijiu, the advantages of Dr. Li's new counting method and new arithmetic symbols are so obvious. It can be regarded as a groundbreaking change in the history of arithmetic."
Although Kong Yingda did not specialize in arithmetic, he did do some research on arithmetic. He heard this and nodded in agreement: "Indeed, your arithmetic school will officially rise in the future!"
After a while, after they all finished copying, Li Zexuan casually wrote five addition, subtraction, multiplication and division problems on the blackboard and said: "Now, you can use the knowledge I just taught you to solve these five problems. I asked five people to come up and do it on the blackboard.”

I forgot to add the title of yesterday's chapter. I'm really sorry, but it seems I can't change it.
Thank you Alone in Loney. My surname is Gong and my name comes from Lao Gong for the reward again and again. Thank you for the first reward of Wangyoucao. Thank you for giving me the "first time"!
Thank you to Alone in Loney, Gong and Chen Haiyan for their monthly votes. Thank you to book friends for their recommendation votes.
