Chapter 66 Exam Paper
"Sunrise! Congratulations! Congratulations!"

"Ah, rejoice and rejoice."

"Risheng, you've been in the limelight this time. Were there any rich people knocking on the door at night last night to ask for relatives?"

"No no."

"Risheng, do you still have the Four Treasures of the Study in your hand? Divide a few from us, and go back for a touch of style."

"Ah this."

In the early morning in Huaidefang, Li Ang smiled wryly as he dealt with his fellow villagers and classmates.

The news of the school's first test release quickly spread throughout Chang'an.

A little-known female student from Youzhou, and a small doctor from Kuangzhou, overwhelmed the son of the prime minister, who was the first-class in the thirteen departments, and won the first and second place in the preliminary examination.

This kind of news is so bizarre that in the early morning outside the gate of Huaidefang Hostel, a group of idle citizens gathered to watch the fun.

No one doubted whether the results announced by the Academy were true, they were just curious about Li Ang.

Li Ang dealt with his fellow villagers and classmates, and looked at the back of them going to Pingkangfang for a banquet again, and shook his head with a wry smile.

The so-called happiness and sorrow, the school only has 5000 people in the first exam, and there are always some who will be eliminated.

However, the examination process of the school was reasonable, and the judging was fair and fair. If he did not make the list, he could only say that he was a bad move and bad luck.

Among the students from Weizhou, Zhai Yiming ranked 110th, Song Shaoyuan ranked 330th, Ji Linglang ranked [-]st, and five others were eliminated—since they had another chance next year, so it was not so much sad.

"I didn't expect to come back with the second place in the exam this time,"

Li Ang closed the door and muttered, "I thought the top [-] would be good."

Chai Cuiqiao asked curiously, "Master, what is the second place?"

"It's No. 2 of the exam."

Li Ang remembered that Yu Guo didn't have the second place, only the champion, or the top, the top.

As for Tanhua, it’s not No.3, but the name Tanhualang is for the young and handsome Jinshi who rides on horseback and picks famous flowers in the garden when the newly promoted Jinshi goes to the apricot garden to play according to the rules.

"It's rather strange though,"

Li Ang murmured: "My scriptures and policy questions are only A-level and A-level, Poetry and Fu B-level, riding and shooting A-level. Logically, I shouldn't be ranked above Pei Jing, who is all A-level in the thirteen subjects. Is it me? The scores of arithmetic, herbal medicine, and danqing are too high?"

----

"Good! Good!"

In the wing of the Chongyefang restaurant, a short and stout doctor of mathematics from the school named Chao Wenyuan was appreciating a test paper repeatedly with joy.Couldn't help but smirk.

Several disciples on the side asked curiously: "Teacher, is this paper really that good?"

"More than good."

Chao Wenyuan shook his head and spread out the test paper full of dense text on the table, "Look, for every question, this examinee is almost dazzling, using more than one method to solve the question.

There is the method of derivation with graphics in the "Jigu Suanjing",

There is also the Tianzhu number algorithm of "Brahman Algorithm" in "Sui Shu Jing Ji Zhi",

and this"

He tapped the corners of the test paper with his fingertips, some horizontal and vertical lines drawn in different squares, and asked the students with a smile, "What do you think this is?"

The disciples approached and recognized at a glance that the horizontal and vertical lines drawn on the test paper were fortune-telling—a notation that was commonly used in the Spring and Autumn Period.

And what these calculations represent.
"Tianyuan Technique?!"

The disciples cried out in amazement.

"That's right,"

Chao Wenyuan let out a long sigh: "Wang Xiaotong, who was Taishi Cheng at the end of the Sui Dynasty and the beginning of the Yu Dynasty, deeply studied the "Nine Chapters of Arithmetic" and "Zhushu", and wrote the "Ji Gu Shunjing", which uses language, text and hooks. Stock patterns and derivations for computationally complex problems.

Xue Gong continued to develop on its basis, and regarded the unknown number of needs as the number of celestial elements, that is, 'establishing tianyuan one',
List two equal Tianyuan formulas, subtract the Tianyuan formulas to obtain a Tianyuan formula, and then use the multiplying method to obtain the positive root, and solve the Tianyuan unknown.

The organization is clear, the steps are neat, and it is faster than the Pythagorean graphic derivation method. "

"The Academy has previously published a paper on Tianyuanshu, and that candidate is really good at learning it by himself."

A student frowned and said: "But the method of multiplying and opening is only mentioned in the paper, and it is not discussed in detail - teacher, you plan to put the method of multiplying and opening together with the quaternary art, and it will be published when it is ready. into a book.

How did he learn it? "

"Learn from the small and know the book, and draw inferences from it. If there is no easy-to-use mathematical tool or calculation method, create one yourself."

Chao Wenyuan said solemnly: "This is a genius!

In the entire math exam, only two candidates, He Fanshuang and Li Ang, answered them all.

He Fanshuang was able to get full marks because she had the ability to get full marks.

And Li Ang got full marks because there are only full marks.

If it wasn't for this, I wouldn't argue in front of the mountain chief and strongly demand that his ranking be placed first. "

Hearing that the teacher praised the student named Li Ang so highly, the disciples present were somewhat dissatisfied.

Seeing this, Chao Wen sighed and said, "The history of the development of arithmetic is an intermittent history.

The continuation and development of arithmetic in ancient times mainly relied on private teaching and family transmission within several households, and arithmetic knowledge was constantly lost and lost.
It was reinvented by later generations after dozens of hundreds of years.

The overall level of mathematics has fluctuated several times, up and down.

It was not until the school paid much attention to arithmetic and regarded arithmetic as an important tool for practical application, the folk customs gradually changed.

It is precisely because of mathematics that we can predict the trajectory of the sun, moon and stars, estimate the wood, stone and earthwork required to build bridges and pavilions, calculate the height of distant mountains, the flow rate of rivers, and even assist in practice.

Instead of using personal experience to 'feel'.

Even if this student named Li Ang fails to enter the school in the end, I will ask the mountain chief for instructions and accept him as a disciple."

As he was talking, Chao Wenyuan suddenly paused, squinted his eyes and muttered to himself, "But Sun Pu, who teaches herbal medicine in the academy, and Du Qinyin, who teaches Danqing, also gave him first-class grades.
Although everyone is a colleague, if you want to grab a disciple with me,
Then don't blame me for turning my face away."

The disciples in the wing looked at each other,
In addition to teaching the prescribed courses, the doctors of the Academy will also select some disciples who are pleasing to the eye and study certain topics together.

Mentors choose students, and students choose mentors.

but
Chao Wenyuan's cultivation base seems to be in the middle of the clouds,

He and Du Qinyin, a female cultivator who was the same age as him in the school, had already broken through to the high-level cloud patrol realm a few years ago.

If they really fight, Chao Wenyuan will probably be hung up and hammered by the other party, just like when the two of them were young.

The disciples present imagined the scene, and decided to shut up, watching Chao Wenyuan sitting in the chair, happily flipping through Li Ang's exam papers, "It's just, why is there a question under the first question? The word 'Solution' that was erased?"

　The "alchemy" in ancient arithmetic is also the "solution of equations" in modern mathematics.

　　During the Northern and Southern Dynasties and Sui and Tang Dynasties, with the spread of Buddhism, some astronomical and mathematical works from India were also introduced into China.

　　For example, "Brahmin Algorithm", "Brahmin Yin-Yang Calculation Calendar", and "Brahmin Calculation Calendar" in "Sui Shu Jing Ji Zhi".

　　At the same time, some astronomers from India with mathematical training held official positions in the Sitianjian in the Tang Dynasty, such as Qu Tan Siddha who compiled the Kaiyuan Zhanjing, which introduced the use of digital data in the Indian mathematics community. to represent numbers.

　　This book is based on this historical data, with slight modifications, and it is assumed that the country of Yu already has Indian-Arabic numerals.
