Lin family, in the study.
After Lin Feng and Bai Yuyao returned from the East Palace, Bai Yuyao went to take a nap. After all, she was five or six months pregnant, and her body was not as strong as an ordinary person's and she got tired easily.
Lin Feng had nothing to do, so he calmed down.
He was thinking about going to Guzang County to take up a post in order to promote land and business reforms. Especially when it comes to land reform, it will inevitably encounter many obstacles and pressures. So, you have to be prepared.
This is the saying goes: know yourself and the enemy, and you can fight a hundred battles without danger.
While Lin Feng was thinking carefully, Gao Xiaoyu hurried in and reported: "Young Master, the Crown Prince and Wang Shangshu are here."
Lin Feng was a little surprised when he heard it.
Ying Yuqian and Wang Tanglai.
what happened?
Lin Feng stood up, left the study and went to the hall. Lin Feng saw Ying Yuqian and Wang Tang arriving hand in hand, and led them to sit down. Lin Feng took the initiative and said, "Father-in-law and uncle came to my place hand in hand. What can I do?"
Wang Tang said: "My dear nephew, I came to visit you because of your method of calculating accounts. This method is extremely fast and unbelievable. I would like to know more about the specific algorithm, and I even hope to learn it."
"This matter is related to the operation of the household department in Da Qin. I also know that the inheritance of a skill is extremely important, and it is generally not even passed on to the outside world. So if you mind, I am willing to accept you as my teacher and learn this skill. "
"I don't know what kind of nephew you are, but would you be willing to teach me?"
The skills of this era were mostly passed down between master craftsmen and apprentices.
This kind of inheritance is rarely in the form of books.
Mostly word of mouth.
Even when many masters and apprentices teach skills, they will reserve some of the skills at the beginning. Waiting until the end, the most important tips will be taught to the disciples.
This is the current situation of most craftsmen.
It was precisely for this reason that Wang Tang made this request.
Lin Feng shook his head and said: "Uncle, it doesn't have to be like this, and it involves arithmetic operations, not complicated algorithms. Here, I have written down all the algorithms and recorded how to calculate. As long as you know how to do it, Once you get the numbers and understand the methods of addition, subtraction, multiplication and division, it will be very simple.”
When Wang Tang heard this, he looked at Lin Feng with admiration in his eyes.
He admired Lin Feng's selflessness.
He admired Lin Feng for not hiding his secrets.
For other people, if they had any amazing skills, they would definitely keep them as heirlooms and hide them away. But Lin Feng was willing to contribute such an important skill, which was admirable.
Wang Tang looked solemn and solemn and said: "I would like to express my gratitude to you sir on behalf of the household department."
He bowed respectfully.
Lin Feng accepted this salute and directly ordered Gao Xiaoyu to get the book "Arithmetic" from the study. This is a mathematical algorithm that he and Bai Yuyao took the time to write down in the past few days when they were studying arithmetic. It involves addition, subtraction, multiplication and division, as well as multiplication formulas and calculation methods.
In addition, it also involves the squares and cubes of some numbers.
This is a bit more complicated.
Even simple linear equations of one variable, linear equations of two variables, and linear equations of three variables are involved. As for the more complex quadratic equations of one variable and quadratic equations of two variables, they have not been covered for the time being.
Nowadays, these methods are sufficient for household accounting, and can at least solve most of all problems.
Lin Feng handed the book "Arithmetic" to Wang Tang, and Wang Tang immediately began to browse quickly. It's just that he didn't recognize it, and when he looked at it at a glance, it was like looking at a ghost drawing a talisman. He couldn't understand it at all, and he couldn't understand it.
Wang Tang looked at Lin Feng and asked, "Mr. Lin, how is this calculated?"
Ying Yuqian also looked over, with expectation in his eyes. He heard his wife say it before and thought it was awesome. The problem is that I have never memorized the arithmetic figures, so I have no impression at all, and I see them in a daze.
Lin Feng immediately explained from 1 to 9. In fact, after knowing the nine numbers, everything became simpler.
The following addition, subtraction, multiplication and division will become familiar quickly.
On a deeper level, in actual accounting, addition, subtraction, multiplication and division are enough.
Wang Tang forced himself to write it down. Under Lin Feng's guidance, he made some calculations and soon became familiar with it.
The more Wang Tang followed this method, the more convenient and simple it became, even faster.
Just so, Wang Tang was even more excited.
He looked at Lin Feng and said solemnly: "Mr. Lin, thank you very much for this. Our Daqin is located in the northwest. Not only does it have few scholars, but such arithmetic has never been involved. It is completely a black eye. Nowadays, , with the book "Arithmetic", things have been completely different since then. Please, Mr. Lin, accept my respect."
Wang Tang bowed again to salute, Lin Feng said: "Uncle, there is no need to salute."
"No, you don't understand."
Wang Tang saluted firmly.
Then, Wang Tang said: "Da Qin doesn't understand arithmetic at all. Da Qin's calculations are almost all done by manpower. Even so, it is not easy. Now with arithmetic, it is even simpler. You deserve this A bow."
Ying Yuqian also said: "My dear son-in-law, Wang Shangshu's words are not exaggerated at all. On behalf of Da Qin, thank you."
Lin Feng said quickly: "I am also from Qin. If I can benefit the Ministry of Household Affairs and the Qin Dynasty, this is what I should do."
For Lin Feng, this is a simple matter.
It's just that Da Qin doesn't have arithmetic.
Wang Tang was already excited and said urgently: "Time is running out, so I won't stay any longer. I'll go back to the Ministry of Finance right away."
Ying Yuqian said: "I will also go back."
Lin Feng said: "I'm sending my father-in-law and uncle away."
"No need!"
Ying Yuqian and Wang Tang followed and left.
The two left the Lin family, Ying Yuqian went straight back to the East Palace, and Wang Tang returned to the household department in a hurry. He took out Lin Feng's book, recorded it carefully, and even calculated it again. After he was thoroughly familiar with it, he called his minister of household affairs.
Today, there are two ministers in the household department.
Cui Zhi, the left minister of Hubu, and Qiu Han, the right minister of Hubu, were both promoted by Wang Tang and were Wang Tang's right-hand men.
Wang Tang looked at the two people standing below and asked: "Now at the beginning of the year, the Ministry of Household Affairs conducts a budget. Budgets involving state allocations and budgets involving the expenditures of various ministries require a general estimate before making any decisions. arrange."
"It's just that the budget is very slow and can't be calculated. What can you do about this matter?"
Wang Tang looked at Cui Zhi and Qiu Han.
He did not immediately bring up the "Arithmetic" invented by Lin Feng, but asked.
Cui Zhi was in his early forties, with a Chinese character face, thick eyebrows and big eyes, giving people a rather honest feeling. He took the initiative and said: "Master Shangshu, regarding the budget issue. Our Ministry of Revenue really does not have enough manpower."
"The humble way is to ask His Majesty to increase manpower. Only in this way can we solve the problem quickly. Otherwise, a mountain of documents and accounts, all of which must be budgeted in a short time, will be impossible to accomplish."
"If there is no one, then the speed will have to be affected."
Cui Zhi said: "This is the truth, not an excuse. You should know this, Lord Shangshu."
Qiu Han echoed: "Master Shangshu, the situation in the Ministry of Revenue has been like this every year. It is extremely busy at the end of the year and the beginning of the year. This matter is a commonplace. Either increase the number of people, or just keep delaying the solution. Your problem is really unsolvable. Don’t you still understand the situation in our household department?"
Wang Tang said: "There is no way?"
"No!"
Cui Zhi and Qiu Han answered in unison.
A smile appeared on Wang Tang's lips and he said, "I do have a solution here."
"any solution?"
Cui Zhi and Qiu Han spoke together again.
Both people had expressions of disbelief on their faces.
Cui Zhi and Qiu Han were both promoted by Wang Tang. They were familiar with Wang Tang's style of doing things, so they didn't have many restrictions.
Wang Tang took out the book "Arithmetic" from his sleeve, patted the book and said, "This is the book I brought back. Next, I will rely on this book to solve all the accounting problems of the Ministry of Household Affairs."
"Come here, bring me a population account book that was calculated in Liangzhou last year."
Wang Tang ordered.
The attendant quickly went to the warehouse to get an account book and placed it in front of Wang Tang.
After Wang Tang opened it, he looked at the data recorded in the account book and said slowly: "The records in this account book are not complicated, and can even be said to be simple. The population data on this first page is the number of people who died and died in Liangzhou last year. The number of births and how that compares to the year before.”
"Last year, 53,698 people died in Liangzhou, and 85,236 people were born. 58,700 people died the year before last. Fifty-six people. The population born the year before last was 84,345."
"The calculation on the first page is the difference between the number of deaths and the number of births this year. At the same time, we will also calculate the increase or decrease in the number of deaths and births compared to the previous year."
"With this data, we can make comparisons. According to our previous calculations, the data is very large, and the calculation is more complicated and takes a certain amount of time. However, look at my current calculation, it is different, and it is even faster. .”
"It might have taken at least an hour originally, but now, it only takes a short time."
Immediately, Wang Tang listed the data numerically and wrote down the formula of the number of births minus the number of deaths. In just a moment, the results were calculated, and the number of births increased by 31,538.
This is the result of an excess birth-to-population ratio.
Because Wang Tang was still a little unskilled, he was a little slower.
In fact, it can be faster.
Even so, it is calculated directly.
This scene fell into the eyes of Qiu Han and Cui Zhi. Although they could not understand the ghost talisman written by Wang Tang at all, looking at this scene, it seemed to make sense. The two looked at each other, inexplicably surprise.
I don’t understand, but I am curious.
Wang Tang looked at the expressions of Qiu Han and Cui Zhi, smiled softly, and continued to calculate. Subtracting the number of deaths this year from the number of deaths in the previous year, the final number of deaths decreased by 5,058. Then, the number of new births this year was subtracted from the number of new births last year, and the final result was an increase of 891 people.
Data calculation is extremely fast.
In a short time, the calculation was completed.
In fact, in future generations, elementary school students will be able to calculate this. The problem is that Da Qin's arithmetic is almost blank. Especially here in Da Qin, even Confucianism is difficult, and there are not many people who know how to learn, let alone such arithmetic.
Just so, Lin Feng's simple arithmetic seemed to open a skylight, which was very shocking.
That's why Wang Tang is so solemn.
Qiu Han and Cui Zhi looked at the ghost painting data written by Wang Tang. Although they could not understand it, when they heard the answer reported by Wang Tang, compared with the confirmed answer, they were exactly the same. Their eyes widened with surprise on their faces. This What is the method?
So quickly?
Cui Zhi said: "Master Shangshu, what is this?"
Qiu Han also smacked his lips, and asked in shock: "What did you invent? How could it be so fast?"
Wang Tang couldn't help laughing when he saw that the two of them didn't understand, and said: "You don't understand this algorithm. Come on, I will tell you about it. After I tell you, you will understand." "
He himself was half-informed, but he couldn't resist the sense of superiority that he knew first, so he explained the numerical symbols from 1 to 9 in a gourd-like manner. After the explanation of these nine numbers, Wang Tang then explained the symbols and calculation methods represented by addition, subtraction, multiplication and division.
Wang Tang explained them one by one, and even set up special questions for Qiu Han and Cui Zhi to perform simple calculations.
After Wang Tang explained it, Cui Zhi and Qiu Han quickly understood. They were both shocked. This arithmetic was really profound, simple and fast.
Really fast.
So useful.
This is very helpful for household accounting and budgeting.
You must know that today's household accounting and budgeting are often confusing and cannot be calculated at all.
Now, it can be clarified.
Qiu Han couldn't help but ask: "Master Shangshu, did you invent this? This calculation method is really profound and profound, and it is extremely fast."
Cui Zhi said: "Master Shangshu is extremely smart and admirable."
Wang Tang stroked the beard under his chin and felt very proud, but he shook his head and said: "How do I know this? If I knew this, I wouldn't keep it hidden all the time. Instead, I would have pushed it out long ago to solve the problem in my household department. Dilemma.”
"This calculation method was given by Lin Feng, who invented "Arithmetic". I also asked him for the calculation method. Originally, I was planning to worship him as my teacher and learn this calculation method."
"But Lin Feng will give you the explanation unconditionally."
"This arithmetic book records many calculation methods in detail."
When Wang Tang mentioned Lin Feng, his eyes were full of admiration.
This arithmetic is so subtle.
Qiu Han said in surprise: "Lin Feng is both civil and military, how can he even understand such side calculations? Master Shangshu, please just invite Lin Feng to come to our household department. It would be a pity for someone like him not to come to the household department."
Cui Zhi quickly agreed: "Yes, yes, brother Qiu Han is right. Lin Feng has not yet become an official, so this is our opportunity. In my opinion, letting him come to the Ministry of Revenue is the best arrangement and will be beneficial to Our household department will solve the problem."
Wang Tang chuckled and said: "The Household Department can't accommodate people like Lin Feng. He has his own arrangements. You don't have to worry about this. What you have to do is to learn it in the shortest possible time and then pass it on. All households Everyone in the department must learn "Arithmetic" and learn to be familiar with it as soon as possible. All future accounting and all data will even be written in arithmetic."
"Here!"
Qiu Han and Cui Zhi answered one after another.
The two of them will not dislike each other, and even after learning this, their own disciples can pass it on.
Arithmetic is extremely useful as an aid to learning.
Wang Tang said again: "The people in my household department have received Lin Feng's favor. When they see Lin Feng in the future, they will respect him as a teacher. Do you understand?"
"clear!"
Qiu Han and Cui Zhi answered again.
Wang Tang waved his hand and said: "You all already understand the general calculation method. Take the book "Arithmetic", each copy a copy, and then return the original to me. Within a month, everyone in the Ministry of Revenue will Learn, you can make your own arrangements."
"Here!"
Qiu Han and Cui Zhi answered again.
The two looked at each other with a look of competition in their eyes.
This is the time to look at each individual’s abilities.
Under the arrangements of Qiu Han and Cui Zhi, Hu Bu's calculations were quickly promoted. The news reached the palace two days later. Ying Jiuxiao also learned about Hu Bu's situation. He asked Wang Shun in detail and got Hu Bu's information. Regarding the current situation, Wang Tang was called to the palace for questioning.
Ying Jiuxiao looked at Wang Tang and asked, "Wang Qing, is the "Arithmetic" knowledge given by Lin Feng really useful?"
Wang Tang suddenly became excited and said quickly: "Your Majesty, the book "Arithmetic" is really profound and profound. The calculations it contains are extremely easy to use. This knowledge can be used to establish a sect. The shopkeeper of the restaurant and the rest of the assistants Officials, as well as officials in the Ministry of Revenue, can use it wherever calculations are needed. The more I think about it, the more I feel that this arithmetic is profound and profound."
"Hahaha……"
After Ying Jiuxiao heard this, he stroked his beard and laughed.
Laughter, extremely contented.
He narrowed his eyes slightly and said proudly: "I have such a keen eye that I discovered Lin Feng's ability early. In the past, he was the one who solved the trouble when Yan Changge came to make trouble, he was the one who guarded the palace when the prince rebelled, and he was the envoy when various countries came to attack. Disintegrated. Now Lin Feng has solved the problem of the household department. Okay, okay! I really don’t know how to reward him."
Wang Tang said: "Your Majesty, I have a suggestion."
"What advice?"
Ying Jiuxiao also asked with a smile.
Wang Tang said: "In the past, when the Lin family was in the Xia Kingdom, Lin Jiuxiao was given the title of Marquis of Zhenguo because of his great achievements on the battlefield. When Lin Yuanzhong arrived, he was also given the title of Marquis of Zhenguo by the Xia Kingdom's court."
"When Lin Yuanzhong dies, the Lin family will no longer have a title, and neither will Lin Feng. In accordance with the wishes of the minister, in the name of Your Majesty, an edict was issued to commend Lin Feng for his meritorious service as an envoy to Jin and Qi, and he was granted the title of Marquis of Zhenguo. The plaque of Zhenguohou Mansion is hung on the door of the Lin family."
"Even for this matter, people were arranged to deliver the decree, and then people were beaten with gongs and drums, and the plaque was delivered with great fanfare."
"In this way, it shows his merits."
"At the same time, it also gives the Lin family a title in the Xia Kingdom, which is expected to be a good reward."
Wang Tang said: "In the future, if Lin Feng makes further contributions, he can be further rewarded. After all, if he goes one step further, he will be the Duke of Zhenguo, or the title of Duke of other countries. This is the limit of human ministers, and the next step is to be crowned king. After so many years in the Qin Dynasty, But there are very few people with the same surname as Wang."
Ying Jiuxiao's eyes lit up and he said with a smile: "Wang Qing, you are right, this is the arrangement."
Wang Tang said: "Your Majesty is wise."
Ying Jiuxiao said: "On behalf of me, you will personally deliver the message and be personally responsible for delivering the plaque."
Immediately, Ying Jiuxiao wrote an edict and asked people to quickly build a plaque with the four words "Zhen Guohou Mansion". When the chamberlain came to report that everything was ready, Ying Jiuxiao looked at Wang Tang and ordered: "Wang Qing, go ahead."
"I obey the decree."
Wang Tang turned around and left.
Wang Tang first went to the Ministry of Industry to collect the plaque from the Zhenguo Marquis Mansion, and then led a group of soldiers, beating gongs and drums, and swaggered out of the imperial city towards the Lin family's residence.
This movement was extremely huge.
It spread throughout the city immediately.
