It took a whole afternoon for the third girl to finally learn how to use these simple mathematical symbols, although it was a little slower than Zheng Qianqian's learning speed, but it didn't take long. Pen "Fun" Pavilion www.biquge.info

Since coming to Yishui County, the living expenses of the entire yamen are managed by Bauhinia and the two women in green clothes to assist Chen Chuchu, and the three girls are tired after returning to the room every night, with this simple mathematical symbol and formula, the three women can quickly calculate the daily income and expenditure, and display it with mathematical reports, which not only saves time and effort, but also is much more intuitive than writing with redundant words.

Li Jin wants to try these low-level mathematical knowledge in his own small area for a period of time, and if the effect is satisfactory, then popularize it. In this way, mathematics teaching can be widely promoted in the local area, which can greatly improve the development speed of the local business economy and change the current business analysis model.

After dinner, Li Jin called Su Yuyang and a group of important people, told them about the establishment of mathematics teaching, and after briefly teaching them, he watched them study on their own.

In fact, it's okay, if a person who can get to this point is uneducated enough to even know the arithmetic of addition, subtraction, multiplication and division, he can be expelled from the organization directly.

Just memorizing and writing those symbols and all kinds of rules that are different from traditional arithmetic gives them a headache. But soon, most of them, including Su Yuyang, had roughly understood.

But then, Li Jin did not let them go away, but gave them a task, that is, to calculate and list a table with new symbols, a table covering the population, farmers, fields, annual grain output and so on of Yishui County.

Reading it was the first time for them, Li Jin was still a little sympathetic, just asked them to make a brief summary table.

Li Jin, who has crossed over, now has the most headache not to read those ancient books with splendid articles and gorgeous rhetoric, but those things about data, such as account books, such as some quantitative descriptions, which make him want to kill the most.

What a table of modern mathematics! It is clear and clear at a glance, which is not only conducive to writing statistics, but also convenient for reference. On top of that, it's easy to calculate various data models. Let his subordinates, or Li Jin, a county official, as long as he remembers the data in his head, he can have a clear understanding of the local operation situation.

For a person like Li Jin who has gone to school and work, whether it is a company or a country, even the organization that Li Jin is now leading must establish a huge and complex data model. Many things, as long as the data changes before and after, you can immediately know whether it is good or bad, and many things, only speak with data.

Just talking about taxes, if there is a detailed list of taxes, then as long as you compare the tables of last year and this year, you can see whether Yishui County is rising, or which is the problem, and then conduct targeted investigation and analysis, find out the crux of the problem, and prescribe the right medicine, in this way, it will be much simpler to deal with official business, not only simple, but also very clear in concept.

For another example, for some big leaders of several organizations under his command, as long as he dispatched a secret agency, secretly sampled the support rate and pass rate in all aspects, and came up with a data table, Li Jin could simply judge whether the leader was qualified or not.

Another example is to establish and improve a basic data table for a certain place in Yishui County, which is updated statistically once a year, and as long as you look at the changes between various data, you can confirm its performance and benefits.

Although the people of the Rain Shadow Organization and the Xiaoyao Sect are currently obeying Li Jin's orders, it cannot be ruled out that some people will have changes after a long time.

In fact, for these two organizations, Li Jin is a very abrupt airborne boss, before this and even now he does not know these two organizations very well, such a leader is easy to be questioned by the people below, so Li Jin is ready to make plans early.

If it was before, these two organizations would be the opposite, and if you don't want to be the leader or sect master, you can run your own Flying Eagle Organization and live a peaceful life with a few wives.

But now it doesn't work, not only did he promise his eldest wife Chu Chu to unify the Demon Gate and complete the great cause of the Demon Gate, but he was also involved in the whirlpool of the struggle for imperial power, and the most important thing was that he didn't want to go down in the nest and wanted to achieve a career.

Then this needs the support of the two major organizations of Xiaoyao Sect and Yuying, and in time, when they are full-fledged and have a certain foundation in the imperial court, and after gaining a firm foothold, they will definitely break these two major organizations into pieces and reorganize them into their own Flying Eagle Organization.

Since Brother Li Jiannan and the old man handed over these two organizations to me, there is no reason to abandon these two organizations and let their wishes go to waste.

And now to develop big data flows, in the long run, this will be of great benefit to their own management subordinates. But the promotion of the data model is definitely not a matter of one or two days, a year or two, and Li Jin does not expect to see obvious results in the short term.

First demonstrate it in a small area in Yishui County, if the effect is significant, then it will be popularized, as long as the economy and culture of Yishui County are up, I am not afraid that there will be no political achievements, and there will be no opportunity to add officials to the knighthood.

But it's easy to conceive, but it's not easy to do. It took the whole afternoon not to mention, and also put Su Yuyang and Yu Ban's gang in the first half of the night. It wasn't until a sub-hour later that they each compiled a rough data table.

Wait for them to check their respective forms, find faults, or even recalculate them. And so on until the sky is dark. It's a simple form that's okay.

It only took Li Jin a few minutes, and after reading the table, he had some impressions of some of the population and agriculture in Yishui County. Total population: 12,000. Total grain fields: 32,000 mu. Total population of rural households: 7,000. Total annual grain output: 57,600 quintals. County government grain tax: 1730,000 quintals, equivalent to 1.65 million copper coins.

Li Jin groaned, took a pen and calculated it himself, and then asked those subordinates who were already sleepy and drowsy: "In this way, the per capita annual income of a peasant household with a population of 7,000 can reach about four quintals of grain. Su Er told me before that including the elderly, children, and women in their prime, if the per capita annual consumption is a little bit and a half quintal, they can basically eat their bellies. It seems that the life of the farmers in Yishui County is not as bad as imagined. ”

Su Yuyang poured a sip of tea fiercely and lifted his spirits.

"Boss, you don't know. Today's grain fields are mostly concentrated in the hands of landlords, and landlords are more ruthless than the government in extracting grain rents. Just now, I have already roughly calculated using the method taught by the boss, purely in terms of the peasant population, an average of only 1.7 quintals of grain can be produced in a year. ”

"One point seven quintals, one hundred seven quintals."

Li Jin's face seemed to be gradually becoming a little ugly. On the surface, it seems that one point and seven quintals can feed everyone, but this is just an average. He also knew to some extent that some fertile fields would always produce more than barren land, and that the average was only barely enough to feed people.

In other words, a large number of peasants, after a year of hard work, may not be able to eat enough every day.

Su Yuyang, the dog-headed military advisor, did not act in vain, and deliberately went deep into the people to understand it.

"Boss, the poor people also have their own way of life, not to mention frugality. As the saying goes, relying on the mountains to eat the mountains, relying on the water to eat the water, you can also raise some things, chop some firewood, net some fish, or raise some poultry and the like. More or less, it can also be used to supplement some household use. The vast majority of people are just living a miserable life and starving. ”

After a pause, his face seemed to be a little ashamed, and he sighed and said: "But this day is just a normal year's days, once there are various natural and man-made disasters, there will be many poor people whose families will be cut off from food, and they will not be able to live, just like this bandit......"

After hearing this, Li Jin also frowned thoughtfully......

Even if it is not for the sake of making some political achievements for himself to climb up, it is just for the poor people who have suffered here for many years to solve the situation of food shortages and soaring food prices this winter.

"It seems that we can only start from this group of fat and oily landlords......"
