11. Step by Step Calculation (Please Read Later)

The next day.

Prison No. 24.

The jailers carried a eucalyptus table with peeling paint and a long bench to Xu Xing.

There were pens, inkstones, and a topaz armrest on the table.

"These are the four treasures of the study..."

"The best Chengchi inkstone, Jinsong inkstone, and the paper and pen bought at Wenchangzhai..."

Captain Deng of the Tianlao walked into the cell with a bundle of paper. He glared at Xu Xing and said, "Commander Liu agreed to your request, but within three days, we must see your results..."

"Otherwise, all these will be removed."

"Also, Old Wu, you keep an eye on him. Don't let him write anything." Captain Deng ordered a clerk behind him.

The reason why Tianlao didn't have paper and pen was that they were afraid that these prisoners would suddenly make random accusations and leave evidence.

When people are pushed into a corner, anything can happen.

"Yes."

Xu Xing nodded and agreed.

He didn't fight for power and say that he would see the result today.

A momentary dispute of will is useless.

The reason why he asked for paper and pen through connections was not to write mathematics.

The real purpose was to use it for something else.

Captain Deng left with a group of jailers, leaving only Wu Shuban and Xu Xing living together.

Wu Shuban was an old official. Although he had been sitting in the corner of the cell sipping tea, his eyes had always stayed on Xu Xing, never leaving, with a face full of competence and sophistication.

Xu Xing ignored Wu Shuban and treated him as air.

He first thanked Su Xueshi, then sat directly on the long bench, rolled up his sleeves, took out a wolf-hair brush from the pen holder, spread out a piece of rice paper, and slowly ground ink with one hand.

The faint scent of ink spread, exuding the fragrance of pine smoke.

Write.

Lines of mathematical formulas and step-by-step reasoning and proof were displayed on the plain paper.

It looked extremely complicated.

After a while, Wu Shuban approached with a teacup.

He took a look and felt dizzy.

However, he carefully read what Xu Xing wrote on the rice paper, and after understanding the annotations of the formula in the different characters..., he carefully compared it with the formula written on the rice paper, deduced and verified it, and found that it was indeed well-founded.

They, the clerks, inevitably deal with mathematics in their daily lives.

Therefore, they have also learned some mathematics in their daily lives. Although they are not profound, they know more than ordinary scholars.

Gradually, Wu Shuban was fascinated by it.

…

…

"Fortunately, I bought a copy of "Tan Tian" from the Mohai Bookstore early in the bookstore, otherwise, with my mathematical attainments..., I can deceive ordinary people, but if I study more, I won't have this ability..."

Weijing Academy, in the house.

Xu Xing flipped through the thick book and secretly rejoiced.

Through the bronze ancient mirror, he can see what he is reading in the copy world.

With this, he copied the Western geometry, algebra, and astronomy involved in "Tan Tian" onto white paper. He can deceive the officials of Fengxi Country.

The culture and customs of the two worlds may be different, but mathematics is the same.

One plus one can only equal two, not three.

The mathematical theory in the copy world is obviously higher than that of Fengxi Country. No one will find it unusual if he forges like this.

The Mohai Bookstore was established on November 3, the 23rd year of Daoguang, and was set up in Shanghai.

It is the first printing house in modern Xia.

"Tan Tian" is a Western book translated by Li Shanlan and Wei Lie Ya Li, which is very popular in China. Weijing Academy, which advocates practical learning, even set it as a must-learn book for students in the academy.

The academy does not issue books, so Xu Xing went to the bookstore outside to search for a while before buying this book.

"Brother Xu, the academy exam will be in two days."

"These few days, you can help me with geometry, not for nothing. I will give you two taels of silver before the exam, and another two taels of silver after passing."

Chen Jianan pushed the door and entered the house, and talked about business with Xu Xing.

Weijing Academy has an exam every ten days.

The examinations in the two halls are different. Shimin Hall only tests practical knowledge, while Rixin Hall has more art in the imperial examination, including the question of copying scriptures, the question of ink meaning, and the most important art. In terms of quantity, it is almost the same as the imperial examination.

Chen Jianan is a young master sent by his father to study in Weijing Academy at a great price, but he is not a scholar who was admitted to the academy.

He entered the academy to study, not for anything else, but to make connections in the academy.

He hopes that his classmates will escort his family's business in the future.

Friendship between the poor and the common people is the most true.

Of course, if he really learned skills in the academy and won the title, it would be a pleasant surprise for the Chen family.

There are many young masters like Chen Jianan in the top academies.

After all, not everyone is a seed of learning.

In the imperial examination system, only fifty people are selected for the county examination, only fifty people are selected for the prefectural examination, and only fifty people are selected for the provincial examination. It can be said that the provincial examination, which is held every two to three years, only delegates fifty scholars.

(Fifty is not a fixed number, but about fifty. The county examination and the prefectural examination select about fifty people, and the provincial examination selects one-tenth of the scholars who participate in the provincial examination as scholars.)

These are the scholars of a province, who compete for these dozens of places in two or three years.

There are more papers than in the civil service examinations of later generations.

"Okay..."

"Brother Jianan, please ask me for advice. I am not a person who cherishes my own possessions."

Xu Xing took the two taels of silver handed over by Chen Jianan and chuckled.

These two taels of silver are said to be the tuition fees given by Chen Jianan to him, but in fact they are just a means to win him over.

He sees through it, but does not say it.

With interests in communication, the relationship between each other will deepen faster.

And he is also short of this little money now.

"But Brother Jianan, I also have something to ask you."

"Confucian classics... well... I haven't mastered them thoroughly, so I'm afraid I won't do well in the exam. I see that you have "Small Topic Essays", "Three Thousand Selections of Large Topic Essays", and "Small Topic Essays Sequel". I wonder if Brother Jianan would be willing to lend me the books to read."

After teaching Chen Jianan geometry, Xu Xing proposed the idea of ​​borrowing books.

He didn't borrow books randomly.

"Three Thousand Selections of Large Topic Essays", "Small Topic Essays", and "Small Topic Essays Sequel" are the necessary model essays for the imperial examinations in the Qing Dynasty published by the Tongwen Book Bureau in Shanghai. The book is divided into six categories according to the Four Books: "University", "The Doctrine of the Mean", "Shang Meng", "Xia Meng", "Shang Lun", and "Xia Lun", and is divided into small questions and large questions.

Each different proposition includes model essays of different authors and styles, all of which are explained by famous scholars.

It can be said that after memorizing these imperial examination model essays, the imperial examination will be as easy as God's help.

The questions given by the examiner basically do not exceed these imperial examination model essays...

As long as he copied all these model essays, it might be difficult to pass the provincial examination.

But the county examination...,

What's so difficult about the county examination? The level of the county examination is not that high.

As long as he passes the county examination, his luck will surely improve a lot, and his fate will also change accordingly.

The subsequent prefectural examination and provincial examination are not difficult either. With the model essays as reference, even if the essays he writes are not satisfactory, the possibility of success in the imperial examination is undoubtedly much greater than that of others.

"You and I are roommates, can I borrow anything from you..."

"Just take it and read it. I have a headache looking at them."

Chen Jianan generously opened the bookcase and let Xu Xing choose.
