Yang Shiqi didn't care about the eyes of others, and said loudly after a little deep groaning: "A few years ago, the old man went to the pawnshop in the capital to make some jewelry, and I listened to the shopkeeper talk to me about a question, so interesting, today I will talk to the two of you?" After speaking, he didn't care whether the two agreed or not, and read it to himself: "There is a loan for thousands of dollars today, and the monthly interest is thirty." Today, there is a lender of 750 yuan, and he will return it in nine days, and he will ask what is the interest?"

Yang Zheng almost didn't laugh when he heard it, and scolded secretly: "You are not ashamed, you have been making a mystery for a long time, but you just made an arithmetic problem, and the arithmetic problem is just like that, and it is so simple to get it alive, and you are not afraid that these sons will laugh off their big teeth?"

But the strange thing is that no one on the field laughed, and the atmosphere on the field suddenly became a little strange.

Yang Zheng was a little puzzled, and said in his heart: "It's just a university scholar, you don't need to be like this for your debut question, right?" Squinted at Shen Gongzi, and saw Shen Gongzi, who was full of confidence just now, but he frowned and said nothing at this time, as if he had encountered some very difficult morale.

Yang Zheng muttered: "It's just a math problem, how can it be like a dead parent?" How did he know that these pretentious talents, sons, poems and songs, and even piano, chess, calligraphy and painting, no matter how powerful the Confucian classics can be recited smoothly, but they are not very bright in arithmetic, not that they have not learned, the traditional Chinese Confucian teaching concept, which requires students to master the six basic talents, also refers to the general term of the disciplines of ancient Chinese higher education, this kind of learning includes etiquette, music, archery, royalty, calligraphy, There are six subjects of mathematics, including politics, morality, patriotism, and behavioral habits, music includes music, dance, poetry, etc., archery is the training of archery skills, imperial is the cultivation of chariot driving skills, books are literacy education, and mathematics and other natural science and religious skills are taught. Its germination has seen the signs in the Xia Dynasty, and it has been gradually improved in the business generation. The characteristics of the "six arts" education are that they pay equal attention to literature and martial arts, seek knowledge and ability, and pay attention to the differences in age and the course of disciplines.

Among the "six arts" of etiquette, music, archery, and royalty, they are called "great arts", which are necessary skills for nobles to engage in politics, and they should be studied in depth at the university level; books and mathematics are called "small arts", which are needed for people's birthdays and are compulsory courses in primary school. At that time, the children of the common people were only given the education of "small arts", and only the children of the nobles could receive a complete education of the "six arts" and complete the systematic process from "small arts" to "great arts". The "Six Arts" serve the needs of the class, but they also reflect the universal laws of education and have always been used.

After Emperor Wu of the Han Dynasty deposed the hundred schools of thought, he respected Confucianism alone, Xingtaixue, established a doctor of the Five Classics, and taught with six arts. "Analects", "Classic of Filial Piety", and "Erya" were attached to the Six Arts Strategy, mathematics was still a subject that literati must learn, and the authorities of the Han Dynasty also strongly recommended it, and arithmetic developed greatly.

After the unification of the Sui Dynasty, Emperor Wen of the Sui Dynasty abolished the Jiupin Zhongzheng and began to use the method of sub-examination to select officials.

In the first month of the third year of the emperor's reign, Emperor Wen of Sui issued an edict to promote "virtuousness". In the seventh year of the emperor's reign, he ordered the Beijing officials to be more than five grades, the chief manager, the assassin history, and the two subjects of "Zhixing Xiu" and "Qingping Ganji". In April of the third year of Emperor Yang of the Sui Dynasty, the edict decreed that civil and military officials who have a ministry can be "filial piety and knowledge", "virtuous and generous", "righteous can be called", "clean conduct", "strong and upright", "unforgiving", "excellent academics", "beautiful literary talents", "talented generals", "arrogant and strong" and other ten imperial examinations. The second subject of Jinshi and the "trial strategy" to take the scholar, the imperial examination was officially born, and the subjects of the scientific examination were mostly based on traditional strategies. At this time, the content of the imperial examination was still relatively small, mathematics was not the main subject, and Cheng dù, which was valued by the literati, gradually declined.

After the fall of the Sui Dynasty, the emperors of the Tang Dynasty inherited the selection system handed down from the Sui Dynasty and made further improvements. As a result, the subjects of the imperial examination have also changed, and there are more than 50 kinds of permanent subjects, such as Xiucai, Ming Jing, Jinshi, Junshi, Ming Law, Ming Zi, and Ming Calculation. Among them, the subjects of Ming Law, Ming Calculation, and Ming Characters are not taken seriously. Junshi and other subjects are not held often, and Xiucai is a subject, which was very demanding in the early Tang Dynasty, and later gradually abandoned. Therefore, the two subjects of Ming Jing and Jinshi became the main subjects of the regular subjects in the Tang Dynasty (Jinshi examined Shishi Shixue and poems, articles, and Ming Jing examined Shishi Shixue and Jingyi; the former is difficult, the latter is easy). By the time of Xuanzong of the Tang Dynasty, the basic spirit of the imperial examination was that the Jinshi emphasized poetry, and the Ming scriptures emphasized the scriptures and Moyi. The so-called scripture is to open a page of the scriptures, cover the left and right sides, only open a line in the middle, and then cover the three characters with paper stickers, so that the test can be filled. Moyi is a simple written test of the words of the scriptures. As long as you are familiar with the scriptures and commentaries, you can pass the test, and the poetry needs to have literary talent. It was very difficult to get the first Jinshi, so there was a saying at that time that "thirty old Ming Jing, fifty young Jinshi". Mathematics was gradually not taken seriously by the students of the imperial examination.

The situation in the Song Dynasty improved, but it was only short-lived, and under the vigorous advocacy of the imperial examination, arithmetic was still not valued by students.

After Zhu Yuanzhang won the world, he listened to the advice of Liu Bowen and others, and took the position of Bagu, and whether the students could pass the exam mainly depended on the merits of the Bagu Wen. Therefore, ordinary readers often devote their whole lives to Baguwen. Although Zhu Yuanzhang in the early years of Hongwu stipulated that the students should rule one classic, and the subjects were divided into subjects such as etiquette, music, archery, royalty, calligraphy, and mathematics.

In the second year of Hongwu, the regulations were re-enacted, scoring ceremony, archery, calligraphy, and mathematics, and the history and etiquette of the scriptures, and other books, which should be familiar with the students, and they must learn to shoot in the shooting garden, study 500 words a day, and mathematics must pass the "Nine Chapters of Arithmetic".

In the third year of Hongwu, Zhu Yuanzhang instructed "Guozisheng and county students to practice archery...... Command the son of the country to shoot the garden and give all living beings bows and arrows". In the twenty-third year of Hongwu, Guozijian built an archery garden and distributed bows and arrows to the prisoners for them to practice martial arts and archery. There is a vacant land on the west side of the Confucian Temple and Guozijian, which is used as an archery garden to assess the level of students practicing archery. In addition, the prefectural school and the county school also built shooting gardens. However, mathematics slowly withdrew from the eyes of the students, and the scholars were just ordinary officials of the Qin Tianjian.

Yang Shiqi's math problem, in the 21st century, is disdainful of ordinary people, but in this era, it is indeed a difficult problem for these sons and talents, and even some sons do not understand the meaning of it at all.

After Yang Shiqi finished speaking, he glanced at Yang Shen and the others with a smile, and said, "Do you two have an answer?"

Shen Gongzi's face turned red, and he bowed his head and was silent.

Yang Zheng didn't understand it for a while, it was just a math problem, and the gist of it was still very obvious, "The loan is seven hundred and fifty, and the interest rate of a thousand dollars is thirty per month; the loan period is set at nine days, how much interest will be paid?"

Yang Shiqi waited for a while, and did not see the two answer, quite proud, he heard this arithmetic for the first time, and it took a lot of effort to come up with the mystery, at this time, seeing everyone's blank looks, quite a sense of pride.

Yang Zheng looked at Yang Shiqi and smiled, the smug look between his eyebrows, he couldn't help but feel a little funny, such a math problem, in his previous life, even ordinary second-grade students could calculate it in one breath, not to mention those monster-like math geniuses in the Olympiad class.

When Yang Zheng was in high school, he was not bad at math, and the "loan of a thousand dollars" in "Nine Chapters of Arithmetic". In fact, the problem is not difficult, according to the problem solving ideas learned in high school, the monthly interest rate in the question is "30 per month", if it is expressed as a percentage, that is: assuming that the borrowing time is one month, then the interest that should be paid for the 750 yuan is: 750×3% = 750×0. 03＝22。 5 (text)

However, his loan period was only 9 days. According to the borrowing convention, if the interest is to be calculated on a daily basis, then it is calculated on a monthly basis for 30 days. So the interest payable for these 9 days is

22。 5/30×9＝750×0。 03＝6。 75 (Text)

So the final answer to this lender's thousand dollars should be 6. 75 (text), Yang Zheng feels that using this kind of topic to test a talented person who reads poetry and books is really a bit of a contempt. But the result surprised him very much, such a simple topic, no one gnawed on it, and even Shen Gongzi didn't say a word.

At this time, Yang Shiqi asked again: "Can you answer?"

Yang Zheng looked at Yang Shiqi, and then looked at everyone with a surprised face, as if he understood a little, these bullshit talents don't know arithmetic at all.

Thinking of this possibility, he almost didn't laugh out loud, these pretentious, unstoppable sons and talents on weekdays turned out to be arithmetic blind, and they still dare to say what show talent does not go out, they know the world, now in front of such a simple math problem, you look at me, I see, no one dares to step forward, this kind of child's deflated feeling, really makes him extremely happy, if he has the identity of the prince, he is afraid that he will lose his royal bearing by laughing, and he really has to say a few loud to express his heart.

No one answered in the small building, no one spoke, and it seemed extremely quiet.

Yang Zheng figured out this possibility, laughed a few times, and then walked out of the crowd, and said with a smile: "Lord Yang's topic is really unusual?"

Everyone waited for a long time and no one stood up, and finally saw someone come out to give their own group of talented people and sons a long face, and when they saw that it was the prince, they suddenly became excited, but when they heard the tone of his words, they seemed to be a little unable to deal with it, and several sons showed disappointment.

A young man shouted with some righteous indignation: "Your Highness, you are our hope, do you want to figure it out?"

"Yes, Your Highness, it's up to you!" another prince also shouted.

"Hey, is this my genius, so disappointing?" Yang Zheng shook his head and sighed.
