Inside the School of Mathematics.
The students sat up straight and listened attentively to Li Zexuan's speech. A capable person would be respected wherever he went. Li Zexuan had already won everyone's respect with his powerful arithmetic ability.
"Hehe, students, in my class, if you have any questions, you can raise your hand 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. That will only accumulate more and more questions. "
Li Zexuan saw that they all looked serious and sat up straight. He couldn't help but say a few words to make them relax.
When the students heard this, they all felt that this way of teaching was very novel. In the past, the teacher was teaching while they listened silently. If they had any questions, they could only hold it in and ask the teacher after class.
Li Zexuan continued.
"I don't care how you studied before. Since I'm teaching, you have to listen to me from now on and learn according to my rhythm. In the future, the School of Mathematics will have a small exam every seven days, a mid-term exam every month, and a big exam every half a year. The first place in the monthly exam will be rewarded with a free meal at the Zuixian Restaurant. You can bring your family and order whatever you want, but you can't waste it.
The last five in the monthly exam will take turns to clean the School of Mathematics before the next exam. In two days, I will ask someone to put up a big sign in front of the School of Mathematics. The first five in the monthly exam will enter the Honor Roll, and the last five will enter the Shame Roll.
As for the first place in the half-year exam, the reward will be 100 strings of coins. Do you all understand? "
The students in the classroom were just applauding Li Zexuan's open-minded teaching system. When they heard this series of rewards and punishments, they were all dumbfounded.
"Ah? The last five not only have to clean, but also enter the Shame Roll? "
"That's so embarrassing. No, we can't be the last five. In the future, we'll have to work late at night."
"The first place can have a free meal at the Zuixian Restaurant. How much is that worth?"
"Wenhao, do you want to fight for the first place?"
"Yes, I will fight for it. I once told my parents that I will take them to the best restaurant in Chang 'an for a meal one day!"
"Okay, I believe you can do it!"
"Brother Shiqing, doesn't that mean the first place is already in your bag?"
"You can't say that. None of us understand Teacher's new mathematics. We all have the same starting point. Oh, the one who is most likely to win first place is Teacher's direct disciple, Iron Egg!"
"Well, that's possible, but isn't that unfair?"
.....
Kong Yingda stroked his beard and did not say a word. In fact, he was thinking to himself, 'This reward and punishment system is quite novel. I'll see how effective it is later. If it can promote students' learning, then I'll promote it to the other academies of the Imperial College. '
These students' reactions were all within Li Zexuan's expectations. After all, no one wanted to lose face. After they quieted down a little, Li Zexuan picked up a piece of chalk, squinted his eyes and smiled.
"Don't worry, everyone. If Iron Egg is ranked first, then the reward for the first place of the month will be automatically extended to the second place. Well, I've explained the learning system of the Mathematics School to you. Next, let's get to know each other. According to the order of your seats, everyone will stand up and introduce themselves. Come, 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 stammered, "Teacher, are you talking to me?"
Li Zexuan also saw that the boy was a little shy, but the root of his shyness was his lack of self-confidence. He smiled gently and encouraged him, "Yes, let's start with you. Don't be afraid. No matter what the relationship between teachers and students was before, from today onwards, we are all a family. We must love each other and help each other. Since we are a family, why don't you stand up and introduce yourself?"
The boy hesitated for a while before he finally plucked up his courage and stood up. He said shyly, "Hello, Teacher. Hello, everyone. I'm Liu Yan from Jinzhou, Hedong Province."
Li Zexuan staggered. What a "domineering" name!
"Hello, Teacher. Hello, everyone. I'm Jiang Qingyu from Jizhou, Hebei Province."
… …
Li Zexuan listened attentively to their self-introductions, memorizing their names and faces one by one. His memory was excellent. By the time all the students had finished their self-introductions, he had already built a database of their information in his mind.
"Well, let's start the class. For the first lesson, I'll teach you a new counting method. Look at these ten numbers on the blackboard …"
Li Zexuan introduced the Arabic numerals to the students as he wrote and drew on the blackboard.
The students looked and listened attentively while taking notes below. Kong Yingda nodded secretly. This way of teaching with the blackboard did make it easier for the students to concentrate.
… …
"Hey, Sister Lan 'er, can you give me your teaching materials? I can buy them for ten strings of cash! "
Look, our Prince of Wei is so generous, directly offering ten strings of cash. He's not like that poor Li Chengqian from before, who had to grit his teeth and beg for half a day to buy a copy of "Journey to the West" before he was willing to offer five strings of cash.
It turned out that Li Tai saw that everyone else was taking notes from time to time, except for Lan 'er and Iron Egg. He glanced at their table and immediately discovered their secret. It turned out that they had teaching materials. So he rolled his eyes, leaned over to Lan 'er, and whispered to her.
Who was the Prince of Wei? Anything that could be solved with money was not a problem. But Lan 'er was a rich woman herself. She didn't care about that little bit of money.
"Not selling? You're the Prince of Wei. You're so stingy!"
Lan 'er pouted and said with disdain.
"Pfft!"
Beside him, Bruiser quickly covered his mouth to stifle his laughter.
Li Tai was speechless. Among all the civil and military officials in the court, only Lan 'er would dare to say that he, Li Tai, was stingy.
"Twenty strings of cash!"
Li Tai said ruthlessly. He didn't believe that this girl wouldn't be tempted by that much money.
Unfortunately, the result disappointed him.
"Not selling!"
Li Tai's face darkened. He wanted to get angry, but when he saw Li Zexuan giving a lecture, he didn't dare to say anything. He could only mumble to Iron Egg and say, "Brother Iron Egg, how about you sell your teaching materials to me?"
Iron Egg thought about it and felt that it was a good deal to sell a book for twenty strings of cash. Moreover, he heard from his master yesterday that these teaching materials …
So he nodded to Li Tai and said, "Okay!"
Then he handed the book to Li Tai.
Li Tai was overjoyed. After being rejected by Lan-er, he didn't have much hope. He didn't expect to receive such a pleasant surprise. He excitedly took over the teaching materials. Without saying anything, he took out a few gold pancakes and placed them on Tie Dan's table.
"Good, Iron Egg. You're a good brother. I, Li Tai, will recognize you as my brother!"
Iron Egg took the gold cookies and was secretly happy. With so much money, he could buy a lot of delicious food for his father and sister!
…
"I've explained the new counting method, the new symbols, and the four arithmetic rules. Here is the multiplication table. Copy it down. You must memorize it by today. I'll check it tomorrow!"
Li Zexuan wrote the multiplication table on the blackboard and said to the students.
As the students copied, they exclaimed that the new numbers and new symbols were too easy to use. It was many times more convenient than using Chinese characters. Xu Hongzhi, who was at the side, couldn't help but praise Kong Yingda, "Chancellor Kong, the advantages of Professor Li's new counting method and new operation symbols are too obvious. It can be considered a groundbreaking revolution in the history of mathematics."
Although Kong Yingda didn't specialize in mathematics, he had done some research on it. He nodded and said, "Indeed. I'm afraid that your school of mathematics will officially rise in the future!"
After a while, when they finished copying, Li Zexuan wrote five addition, subtraction, multiplication, and division problems on the blackboard and said, "Now, use the knowledge I just taught you to solve these five problems. I'll ask five people to come up and do it on the blackboard."
