“The main function of this question is to reasonably calculate the optimal ratio of personnel flow, and then calculate the efficiency of the production line to roughly determine the optimal ratio of skilled workers and unskilled workers in each production line. This kind of calculation is very useful when the scale needs to be expanded." After Li Yan said the topic, she introduced it to everyone.
Then he directly took the branch and scratched it on the ground next to him.
"Let's first assume that the percentages of skilled workers and unskilled workers counted in January of the Nth year are Xn and Yn respectively, and record them as vectors Zn... Oh, you should understand what this letter means..." Li Yan explained these symbols to them while solving the problem. After all, these are the new mathematics that His Highness brought out.
Director Fang couldn't help but secretly raised his head and glanced at Fang Xuanling. "Liang Guogong, are you sure I need to test this thing?" He didn't even understand the question. Although the other party explained it to him, he probably understood it, but could he calculate this thing?
"Actually, the calculation method of this thing is the same as that of a chicken and a rabbit in the same cage... It can be regarded as a more complex variant of "Nine Chapters of Arithmetic Equations"." Li Yan told them about the origin of this thing while solving the problem.
Director Fang: "..."
I know it's a chicken and a rabbit in the same cage, but are you sure these two things are the same thing?
Li Yan finally solved the problem: when N continues to increase, that is, the more years there are, the subsequent N+1 of X and N+1 of Y tend to 0.8 and 0.2 respectively.
The result came out, but everyone was silent.
What should I do if I can’t understand this thing?
They probably know the meaning of these symbols. After all, they have studied arithmetic. Although they may have forgotten some of the arithmetic over the years, they can still understand it somewhat when these things are listed.
But it was just a few, and the overall look was...completely at a loss.
The term equation has long existed, including linear equations of one variable in later generations of Chinese mathematics. The names one-variable and two-variable all come from the "Tian Yuan Shu" of the Song and Yuan Dynasties, but they did not exist in the Tang Dynasty. However, in the Tang Dynasty There are equations, and the calculation of the equation is directly expressed in words.
This difficulty...maybe no problem for people who have learned this expression since childhood, but its difficulty is actually much more difficult than intuitive Arabic numerals.
Any knowledge that can withstand the test of time and ultimately survive is worthy of attention and deep thought. What's more, these numbers are not called Arabic numerals, but Datang numerals, invented by Li Ke.
Arabic numerals were invented in ancient India, but in fact Li Ke has already understood that the modern complete Arabic numerals are completely different in ancient India of this era. It can only be said that it is a bit like the relationship between English letters and ancient Greek letters in later generations. .
So this number is the Tang Dynasty number, there is nothing wrong with it.
Or you can call it King Qin’s number.
No matter what outsiders call it, Li Ke has never named it himself.
But one thing that made Li Ke a little speechless was that he told the ministers before that in the new weights and measures, one pound is equal to 500 grams. As a result, when the ministers wrote it, they all wrote: Ke.
The Royal School has been established for a year. The first one established was the Royal School located in Chang'an City for the children of the clan and the royal family. For the time being, this school only serves as an internal school for the clan and the royal family.
But maybe it will be made public in the future, and I don’t know for sure, but it has not been made public at the moment, mainly because of some of the teaching content. If there are more people from these wealthy families, it will not be convenient for Li Kexi... to carry out ideological and political education.
However, there are other schools in Chang'an City that are open to the public, and many children from well-known families study in these schools.
Therefore, they have all understood the teaching of mathematics.
After the invention of numbers and this alphabet, arithmetic is indeed easier to learn than before. The most important thing is that His Highness has completely arranged the entire arithmetic system, from elementary school to advanced subjects.
They have all seen the arithmetic textbook. In fact, a lot of the knowledge in it has surpassed the basic and important books on arithmetic, but now... what Li Yan is calculating is obviously a higher-end thing, and they have never seen it.
"Is Mr. Fang okay?" Li Yan looked at Mr. Fang and asked.
Director Fang: "..." He really wanted to ask Liang Guogong whether this should be allowed or not.
"Li Shangshu is indeed very knowledgeable in this aspect. Confucius said that if three people are walking together, there must be my teacher, and the master will come first. We are not as good as Li Shangshu in this aspect." Fang Xuanling took the initiative to speak.
When the boss spoke, Director Fang naturally didn't need to speak, he just nodded in agreement.
"Although this is true, I think arithmetic and other aspects are professional abilities. For the operation of a department, not only professional abilities are needed, but also interpersonal relationships, etc. I would like to ask Liang Guogong to give you more guidance in this regard. , I am definitely not as good as all the other princes." Li Yan smiled and slightly arched her hands towards Fang Xuanling and others.
"Of course that's no problem." Fang Xuanling smiled and nodded.
So damn shameless! The corner of Wei Zheng's mouth twitched next to him, and he almost cursed out loud, "Well, you Fang Qiao, dig a hole for me when you ask me to come, and let me object. When you come here, you will agree directly if someone shows your hand, right?" Where is your moral integrity? What's your bottom line?
Your bottom line in relationships is that there is no bottom line, right?
In this case, why did you ask me to come? Can't you just agree to it directly?
"Thank you to the princes." Li Yan said with a smile, "I will hand over a few lists of personnel to the three princes later. These people are the main staff of the central bank that we selected in the early stage."
"No problem." Regarding this, the three of them all understood this, and naturally agreed directly. After all, the people who had previously handed over the entire Central Bank to His Highness, His Majesty and they both knew that these personnel must be appointed directly.
Li Yan handed over the already prepared personnel list to Fang Xuanling and the others, and then went to deal with the office space herself.
After Fang Xuanling and others left, Wei Zheng blew his beard and stared at Fang Xuanling: "Fang Qiao, what do you mean? You pretend to be a good guy and let me pretend to be a bad guy, right?"
"Impossible, absolutely impossible. How can I do this? I'm just telling you that this is an issue related to Mr. Zheng Guogong, so I invited you two to come over." Fang Xuanling shook her head.
"Do you think this old man is a fool?" Wei Zheng asked with a sneer.
"No, no, Mr. Zheng Guo, why are you so angry that you even cursed yourself?" Fang Xuanling said quickly.
"Shameless old man, I don't even bother to be with you, I'm leaving!" Wei Zheng turned around and left.
"Look at you, why are you so anxious when you say this?"
