"Sure enough, it's him. This boy's surprises for me are getting bigger and bigger. I really don't know how many more surprises he can give me." Li Er said excitedly, but at the same time he couldn't wait.

Li Xiangcheng curiously asked his eldest grandson beside him: "Mother, who is this Wang Ning'an? My father seems to value him very much?"

The eldest grandson smiled and said: "He is the disciple of your father's benefactor, and he is full of knowledge. But this man is afraid of death, greedy for money, but also bold. He often makes your father angry. Your father really loves him now."

hatred."

Li Xiangcheng was very surprised that such a person existed.

Li Er said displeasedly: "Stop talking about him. It's getting late. Let's go back to the palace."

"That's fine. Xiangcheng, you have to take good care of yourself when you are alone outside the palace. If you need anything, tell your mother."

The eldest grandson gave a few instructions and then returned to the palace with Li Er. Li Xiangcheng saw them out of the princess' mansion.

Li Xiaogong also accompanied them for a while. On the way, Li Xiaogong also told Wang Ning'an about increasing business taxes on Hu merchants.

Li Er directly denied the matter. It was not appropriate to increase commercial taxes at the moment. He had only been on the throne for one year, so he should use a soft policy. How could he increase commercial taxes?

Wang Ning'an didn't know that Li Er already knew about his plan, agreed to one plan, rejected another, and then fell asleep.

However, when he wanted to take a nap, he was woken up by Qin Huaiyu and Cheng Chumo. When he came out with a depressed look on his face, he found that there was one more person among them, and this person was Chang Sun Chong.

Wang Ning'an said: "Brother Changsun is here, what a coincidence."

Changsun Chong smiled and said: "Huaiyu and Chu Mo live very close to each other, and we often go to Chongwen Hall for classes together."

"Then it will be the four of us together from now on."

"Yes, but you are the master and we are your students." Changsun Chong joked.

"Haha, that's right, that's right, we are students and you are the master. When we see you, we have to say hello to you, master, and do the master's courtesy." Cheng Chumo also joined in the teasing.

Wang Ning'an took advantage of the situation and said: "In that case, why don't you pay homage to me and serve me well, otherwise you may not get any good results in class."

Cheng Chumo smiled evilly and said, "Changsun Chong, did you hear that? Ning'an asked us to take good care of him."

Changsun Chong understood what Cheng Chumo meant and immediately stretched out his hand and said, "Okay, let's take good care of him."

Wang Ning'an realized that something was wrong, and immediately ran forward. After running a certain distance, he turned to Cheng Chumo and Changsun Chong, made a face, and said, "Come after me."

"Chase."

As soon as Cheng Chumo finished speaking, he rushed forward like flying. Changsun Chong laughed and also rushed forward.

Qin Huaiyu smiled bitterly and chased after him. The four teenagers chased and played happily.

After arriving at Chongwen Hall, Wang Ning'an and the others saw their master Kong Yingda, one of the eighteen bachelors.

It is rumored that he is a descendant of Confucius, so he was appointed by Li Er to teach princes, princesses and powerful princes.

He was aroused by Wang Ning'an's words last time, so when Wang Ning'an came to class today, he wanted to learn about the so-called Neo-Confucianism.

"Meet the master." Changsun Chong and the four of them saluted one after another, including Wang Ning'an. The etiquette must not be discarded.

Kong Yingda nodded and said: "Well, it's getting late, let's all go in."

"yes."

Changsun rushed towards them and ran into the classroom quickly, but Wang Ningan was stopped.

"Master, what's the matter?"

Kong Yingda said: "Today is your first time in class. There are some things I need to explain to you."

Wang Ning'an said: "Thank you Master, but no need. I admire Master's teaching very much. Regarding some things in class, I believe I don't need to repeat them again."

Kong Yingda was very impressed by this sentence and said: "That's fine, just go in."

"Thank you, Master."

After Wang Ning'an walked into the classroom, Kong Yingda followed him. The prince, princess, and a group of sons or grandsons of the boss immediately became quiet in the classroom.

When Kong Ying walked to the end and Wang Ning'an walked to the podium, everyone started talking.

They felt strange that someone about the same age as him, or about the same age as their eldest brother, would become their husband.

"Quiet." Wang Ning'an and Kong Yingda said in a deep voice at the same time.

Especially Kong Yingda, who had just been told by Wang Ning'an that these students were of high quality, but turned around and made such a big fuss, which made him lose all his dignity.

Under the scolding of the two people, the scene suddenly became quiet.

Wang Ning'an said with satisfaction: "Very good, if you can calm down and listen to me, it means that you have accepted my identity as master.

I know you are very conflicted right now, but none of us can disobey His Majesty’s appointment. I am your master in class, I am the biggest, and you must listen to what I say.

After class, we can be brothers, friends, or your elder brothers.

Today, the lesson I am teaching you is arithmetic in science, which is also the most widely used subject in the science of use.

Arithmetic is used in almost half of the industries. Some only need some simple algorithms, while others require precise calculations to get the answer.

The most common industry, and the one you think is most self-righteous, is the accounting office, an industry that deals with numbers every day, and can calculate a year's worth of accounts with a simple algorithm.

Yes, this is the fact, but what I want to give you is a sophisticated algorithm. If you calculate it to the extreme, you can calculate how high Mount Tai is and how fast the water in a long river is."

Li Tai, King of Wei, said: "Master Wang, since you said you are so good at arithmetic, I wonder how good Master Dao is at arithmetic?"

Wang Ning'an Wei

He looked at the little fat man with a smile and said: "It's beyond your imagination. If you want to know, then study hard. When you can compare with me, you will know. Then you can even surpass me."

"Fourth brother, don't talk too much and listen carefully to the class." Li Chengqian said.

"Oh." The little fat man sat down obediently.

Wang Ning'an nodded slightly to Li Chengqian and felt a little fond of him, not as annoying as when he first met him.

"Okay, in order not to waste everyone's time, I won't talk nonsense anymore. Now I will teach you how to recognize a new number."

As Wang Ning'an spoke, he started writing on a piece of paper with a brush. In less than thirty seconds, the Arabic numerals '0-9' appeared on the white paper.

He raised the paper, faced all the students, and said again: "The numbers on this, from left to right, are 0123456789. I call these numbers lowercase numbers, also called simple numbers, which can make it easier for everyone to remember.

, writing and knowing.”

As soon as the Arabic numerals 0-9 appeared, it instantly caused a sensation in the classroom. This was knowledge that had never been learned before. It was simple, easy to remember, and even easier to write.

The most excited person was Kong Yingda. With his knowledge reaching such a level, only innovation can show that he is a true master. However, none of the articles or other poems he wrote could escape Confucian thought. Wang Ning'an gave him a blow in the head.

.

"Master Wang, these are just ten numbers from 0 to 9, but for us in China, we also have tens, hundreds, thousands, ten thousand, one hundred thousand, millions, etc. Are there ten or hundreds among these simple numbers?

?" Li Tai spoke with contempt again.

Li Tai is a very smart person with a very high talent for reading, so his vision is also very high. He feels that people who are a few years older than him are not qualified to be his wife, so he targets them everywhere.

Wang Ning'an smiled slightly, then wrote four more numbers on the paper, which were 10, 15, 100, and 150. Then he spread it out again and said, "My classmate, have you seen these four numbers? They are ten and fifteen respectively.

, one hundred and one hundred and fifty.

As you can see, a combination of 1 and 0 zeros is 10, and turning 0 into 1 is 11.

By analogy, this applies to one hundred and one thousand. May I ask if this student has any questions?"

Li Tai said unhappily: "No more."

"Okay, then I'm going to show you four symbols." Wang Ning'an once again wrote the four symbols of addition, subtraction, multiplication and division on the paper.

After unfolding it for everyone to see, he said: "These four symbols are addition, subtraction, multiplication and division." Pointing to the '+' sign, he said: "This is the plus sign for everyone to do addition." Then he pointed...

After listening to Wang Ning'an's explanation, the students were confused. They could understand addition and subtraction, but multiplication and division were not clear to him.

Only Kong Yingda kept looking at Wang Ning'an with a horrified look.
