I become a sage by eating books

Chapter 34

With Master Zhou’s permission, Ning An walked to the podium, on which there was a black lacquered board, and then Ning An wrote on the lacquered board:

x+2x+4x+8x+16x+32x+64x=381
127x = 381
x = 3
Students, you look at me and I look at you, but you don't understand what Ning An is writing.He didn't just write it casually to fool them.

Seeing question marks on everyone's faces, Ning An said, "Master, the calculation method of self-study is different from everyone else's. That's because self-study accidentally learned a simple counting method. Please take a look. These are 0123456789, and they will be called below." Arabic numerals"

Ning An talked about addition and subtraction tables from Arabic numerals to ninety-nine multiplication tables and ninety-nine division tables and then to equations. The students were confused, but they faintly felt that the method Ning An used seemed to be a The new knowledge system, if they also learned this knowledge system, then they would be able to calculate as quickly and accurately as Ning An.

Master Zhou looked shocked. He was more perceptive than the students. At first he thought that Ning An just had a special calculation method, but he didn't expect this young man to surprise him. If everyone can learn this kind of knowledge system, then Dayong will count. Undoubtedly it will be a huge change.He couldn't wait to know what the unknown equation of multiplication and division Ning An was talking about.

"Student Ning An, where did you learn this calculation method? This old man has never heard of it." Master Zhou asked everyone's doubts.

Ning An had an idea and said, "This is passed down by my teacher."

"I don't know who the other teacher is, can you recommend it to me." Master Zhou asked.

Ning An pondered, and then made a sad expression, "My master, my master has passed away."

Seeing Ning An's sad face, Mrs. Zhou didn't want to ask more questions, but just sighed, it's a great pity that such an expert has no chance to meet him.

"Ning An, this old man solemnly asks you, I wonder if you can contribute your method for everyone to learn? Of course, it is not a free contribution. On behalf of the head of the mountain, this old man can hire you as the master of Bailu Academy. Is it possible to teach everyone arithmetic?"

Master Zhou's words stirred up waves, and even Ning An was dumbfounded. Didn't she come to be a student? Why did you suddenly want to hire her as a teacher?
"Master, the student is willing to contribute this arithmetic method for everyone to learn together. This can be regarded as fulfilling the teacher's wish. As for the matter of being a master, the student thinks he is not competent, so I ask the master to take it back."

Ning An doesn't have much interest in being a teacher, because teaching a subject of arithmetic has never been her goal, her goal is to be the teacher of the servants.

Master Zhou thought about Ning An's words, and he also knew that Ning An must have his own considerations, but he never thought that Ning An would contribute the method so easily. With his attitude, Master Zhou decided that he must not I've done this boy a disservice.In this way, Ning An has become Master Zhou's year-end friend since then, and a letter was sent to the capital that night.

In this way, Ning An is not only a student in Bailu Academy, but also has a special status, acting as a teacher, known as Ning Xiaofu.

A few days later, in the imperial palace of the capital, Emperor Yan Qi received a specially made brocade from Bailu Academy. After reading it, Yan Qi handed the brocade directly to Crown Prince Yan Huanyu.

After looking at it, Prince Yan Huanyu said with joy on his face, "Congratulations, father, congratulations, father."

Yan Qi raised his eyebrows and asked, "Oh, why do you like it?"

Prince Yan Huanyu is fifteen years old, with a slightly childish face as handsome as jade, and every gesture of his hands is full of nobility.

"Father, if what Wei Shanzhang and Master Zhou said is true, then it will be a huge improvement for Dayong, especially the household department, which will save a huge amount of expenses."

As the king of a country, Yan Qi didn't understand the truth, it was just a test of the prince.That young man named Ning An is only over sixteen, but he can win the favor of several senior teachers, it must be extraordinary, if this matter can be achieved, he will definitely use it.

"Prince, let's go down first. I have already made a proposal on this matter. I will promote it after the successful demonstration of Bailu Academy."

"Father is wise, and my son is retiring."

Ning An, who was in Pingyao County, didn't know that she was famous in front of the emperor.

In the following days, apart from studying, Ning An taught the students in Tianjia class to learn mathematics. After many days of study, the students in Tianjia class have been able to master the basic four arithmetic operations.As for the students in other classes, there will be a few masters of arithmetic who will teach them on their behalf.

At first, many students thought it was unnecessary, but under the tough attitude of Master Wei, the students compromised and had to learn.

Gradually, the students discovered that this calculation method is indeed much simpler, and even people without calculation talents can learn it.Now everyone would call Ning An sincerely when they saw Ning An, and even Xiao Renhuai, who wanted to trouble Ning An at the beginning, would call Ning Young Master when he saw her.

"Master Ning, a big brother asked me to give this to you." A servant handed a package to Ning An.

"Thank you brother."

Ning An sincerely thanked him, and the boy excitedly said "You're welcome" and left quickly.

Ning An was a little baffled, was she that scary?In fact, I don't blame the boy, the main reason is that Ning An's facial features have become more and more handsome and his temperament has become more and more outstanding with the increase in prestige and charm. The boy is afraid that he will lose his composure.

"An An, what is this?" Xie Yu did not know when he stood behind Ning An, followed by Xiao Li.

"It's nothing, let's go, I'll show you something good today." Ning An smiled mysteriously.

Several people walked into the classroom and found that each student had taken a strange thing.Seeing Ning An coming in, everyone asked curiously, "Master Ning, what is this?"

Seeing that everyone was studying the abacus in their hands with great interest, Ning An just smiled gently. How can you learn mathematics without an abacus!It's just that this time she doesn't plan to teach it herself, because she has already taught Master Zhou the method of abacus, and by the way, she also added a piece of income to the family, because these abacus were all made by her elder brother and a few craftsmen in the village. One hundred papers, the students of Bailu Academy are 100 taels.

Ning An doesn't feel like she's doing business for personal gain at all. Ning Yong's carpentry skills are very good, and five hundred cash is considered a friendship price, and she has her own plan. The Ning family can't rely on her forever, and let the Ning family stand up on their own. It is a long-term solution.If she hadn't completed the task after 20 years, the Ning family would not have been too miserable.

As a modern person, Ning An still pays attention to property rights, so Ning An asked Ning Yong to make signs on the inconspicuous places of the abacus. Even if someone imitates it in the future, the Ning family will take the lead.

Master Zhou is very excited today. He can't put it down to the abacus, a new computing tool. This Ning'an really brought him too many surprises. Such a tool should be promoted throughout Dayong. The blueprint and calculation method of the day-counting abacus have already been received.

In the imperial palace of the capital, Emperor Yanqi had someone make an abacus overnight after receiving the brocade from Bailu Academy, and ordered the people in the Ministry of Rites to perform calculations according to the above method. The result was that the calculation speed of the abacus was faster and more accurate.

After class, the students practiced their abacus, and the whole classroom was filled with the sound of crackling and dialing beads. There was only one person who disdained it, and that was Wang Lang. In his opinion, this was something that businessmen used. Like other students, it is an insult to his descendants.

"An'an, how did you come up with such an interesting thing?"
