Datang: Li Shimin begged me to rebel

"The main function of this topic 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 for each production line. This kind of calculation is very useful when the scale needs to be expanded." After Li Yan mentioned the topic, she first introduced it to everyone.

Then he directly took the branch and scratched it on the ground next to him.

"Let's first set the percentages of skilled workers and unskilled workers counted in January of the Nth year as Xn and Yn respectively, and record it as a vector Zn... Oh, everyone should understand what this letter means..." Li Yan explained these symbols to them while solving the problem. After all, these are all in the new mathematics brought out by His Highness.

Director Fang couldn't help but secretly raised his head and glanced at Fang Xuanling, Mr. Liang Guogong, are you sure I need to test this thing?He didn't even understand this topic. Although the other party explained to him that he probably understood it, but can this thing be calculated?

"Actually, the calculation method of this thing is the same as that of chickens and rabbits in the same cage... It is a more complicated variant of "Nine Chapters of Arithmetic Equations." Li Yan told them the source of this thing while solving the problem.

Director Fang: "..."

I know that chickens and rabbits are 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, as the number of years increases, the subsequent N+1 of X and N+1 of Y tend to be 0.8 and 0.2 respectively.

The result came out, but everyone was silent.

This thing... I don't understand, what should I do?

They probably know the meaning of these symbols. After all, they have learned mathematics. Although they may have forgotten some of them in these years, they can probably understand some of these things when they are listed.

But it's just a few, the overall look... is completely at a loss.

The word equation has been around for a long time, including the unary linear equation in Chinese mathematics in later generations. The titles of unary and binary all come from the "Tianyuanshu" in the Song and Yuan Dynasties, but it did not exist in the Tang Dynasty, but the Tang Dynasty There is an equation, and the calculation of the equation is directly calculated by means of text expression.

This level of difficulty...maybe no problem for people who have learned this expression since childhood, but its difficulty is actually much more difficult than the intuitive Arabic numerals.

Any knowledge that has passed the test of time and survived in the end is worth paying attention to and pondering, not to mention that these numbers are not called Arabic numerals, but Datang numbers, which were invented by Li Ke.

Arabic numerals were invented in ancient India, but in fact Li Ke has already understood that the modern and complete Arabic numerals are completely different in ancient India in 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 Datang number, there is nothing wrong with it.

Or it can be called Qinwang Numbers.

Whatever outsiders call it, Li Ke never named it himself.

But one thing that makes Li Ke a little speechless is that what he told his ministers before, in the brand-new weights and measures, one catty is equal to 500 grams. As a result, all the ministers 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 is only teaching as an internal school for the clan and the royal family.

But maybe it will be made public in the future, but it is not made public at present, mainly because of some of the teaching content. If there are more people from these powerful families, it will not be convenient for Li Kexi to carry out ideological and political education.

However, Chang'an City also has other schools that are open to the public, and many children from aristocratic families in these schools study in them.

So they have all been familiar with the teaching of mathematics.

After the invention of numbers and this kind of alphabet, arithmetic is indeed easier to learn than before. Most importantly, His Highness has completely arranged the entire arithmetic system, from elementary school to advanced subjects.

They have all read the mathematics textbook, and in fact, a lot of knowledge in it has surpassed the basic and important books on arithmetic, but now... the thing Li Yan calculated 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 Duke Liang whether this should be possible or not.

"Li Shangshu is really knowledgeable in this area. Master said, three people must have my teacher, and those who have mastered it first. We are not as good as Li Shangshu in this aspect." Fang Xuanling took the initiative to speak.

When the boss spoke, Chief Fang naturally didn't need to speak anymore, he just nodded in agreement.

"Although this is true, I think arithmetic and other aspects belong to professional ability. For the operation of a department, what is needed is not only professional ability, but also interpersonal relationship management and so on. I would like to ask Liang Guogong to teach you more about this aspect. , I’m definitely not as good as the dukes.” Li Yan smiled and slightly cupped her hands at Fang Xuanling and the others.

"Of course there is no problem." Fang Xuanling smiled and nodded.

Too fucking shameless!The corner of Wei Zheng's mouth twitched, and he almost yelled, "Fang Qiao, dig me a hole when you ask me to come, and let me object. When you come to your place, you just agree with him if you show your hand, right?"What about your morals?What's your bottom line?

The bottom line of your relationship is that there is no bottom line, right?

In this case, why did you call me here?Can't you agree directly?

"Thank you a few dukes." Li Yan said with a smile, "Then I will hand over the list of personnel to the three dukes later. These people are the main staff we selected in the early stage to be in charge of the Central Bank."

"No problem." Regarding this, the three of them understood something, and naturally agreed directly. After all, the whole central bank was handed over to His Highness before. Both His Majesty and them knew that these personnel must be appointed directly.

Li Yan handed over the list of personnel that had already been prepared to Fang Xuanling and the others, and then went to deal with the office space by herself.

After Fang Xuanling and the others left here, Wei Zheng stared at Fang Xuanling with beard and stare: "Fang Qiao, what do you mean? You are a good person, let me be a bad person, right?"

"Impossible, absolutely impossible. How can I do this? I just want to tell you that this is a matter related to Zheng Guogong and you, so I invited the two of you here." Fang Xuanling shook her head and said.

"Do you think the old man is an idiot?" Wei Zheng asked with a sneer.

"No, no, Zheng Guogong, why are you still scolding yourself in anger." Fang Xuanling said quickly.

"Shameless old man, I disdain to be with you, I'm leaving!" Wei Zheng turned around and left.

"Look at you, how can you be in a hurry."
