Prosperous Tang Blood Blade

Chapter 193 Convince Xu Jingzong ([-]rd)
Actually Xu Jingzong didn't say anything, Chen Ying also knew that Xu Jingzong didn't take Chen Ying's official position as Marquis Marquis Chief Shi seriously, he was just not forced to make a living, and his reputation was ruined by Feng Lun. I am afraid there is no possibility of recovery within the year.Only then did he plan to borrow Chen Ying's Chen Mansion to study and accumulate fame.

If other methods are used, Chen Ying really doesn't know how to convince Xu Jingzong, but by using arithmetic, he is unlucky, Chen Ying can completely abuse Xu Jingzong, let alone Xu Jingzong, even in this era, even if you count everyone Probably not Chen Ying's opponent.

But Xu Jingzong didn't know, he knew that Chen Ying was extremely brave, good at commanding the army, and also good at poetry and calligraphy, so to speak both civil and military.However, they didn't know that Chen Ying was actually best at arithmetic.

Xu Jingzong immediately made a final decision and said: "If Lord Hou wins, Jingzong will serve Lord Hou as an ox and a horse for five years!"

Chen Ying said with a smile: "If Mister wins, I will protect you as a fifth-rank official!"

Xu Jingzong's heart moved, and he said excitedly: "Really!"

Chen Ying nodded and said, "Really!"

Xu Jingzong raised his right palm and said, "A gentleman!"

"Crack!" Chen Ying and Xu Jingzong swear by high-fiving: "Come on!"

Chen Ying wrote down "12345678" on the paper and suddenly found that Xu Jingzong didn't know this kind of Arabic numerals, so he rewrote it into 1000 two million three hundred and forty-five thousand six hundred and seventy-eight. "

Of course, adding and subtracting the remaining eight digits will be tricky, even if you use a sixteen-digit calculator, you can't figure it out.No one thought that Xu Jingzong would not show any weakness, and directly wrote "nine thousand five hundred and fourty seventeen thousand eight hundred and twenty six"

Chen Ying smiled, picked up the pen and wrote down the number he just wrote on the paper, then put down the pen, and when he looked up, Xu Jingzong had already moved the straw stick quickly, and had written the number on the white paper. The first line of numbers.Obviously the addition has been calculated.

The speed of Xu Jingzong's calculation was beyond Chen Ying's expectations.Fortunately, mathematics is Chen Ying's strong point. Although Xu Jingzong is fast, he is not slow.Chen Ying wrote down -83072148 casually, and then wrote down 107763504 without any pause.Chen Ying raised his head and found that Xu Jingzong's calculation speed of addition and subtraction was almost the same as his, but only a few breaths slower.

However, Chen Ying also knew that the ancient Chinese calculation method of addition and subtraction was very convenient, but the rules of multiplication and division were relatively complicated (Old Cheng would not know it).

Sure enough, as Chen Ying expected, when Chen Ying wrote down 1177995525256, Xu Jingzong's head was already in a cold sweat. When Chen Ying wrote down the division result, 0.1293854462791 Xu Jingzong directly threw the counting chip.

"Xu admits defeat!"

Chen Yingdao: "This is a big food number, which is very convenient to calculate!" So Chen Ying wrote down the Arabic one to nine and one to nine respectively, and then used addition, subtraction, multiplication and division to perform vertical calculations.

At this time, Chen Ying taught Xu Jingzong patiently, just like teaching elementary school students, and Lan Er also listened carefully.In fact, Lan'er's math foundation is even worse, she can barely add and subtract within a thousand, and she is blinded by addition and subtraction beyond [-].However, Lan'er is also relatively smart, with a strong learning ability, and her acceptance ability is much stronger than that of junior high school students in later generations.

Lan'er suddenly pointed to the "-" written by Chen Ying and asked, "What's the explanation?"

Xu Jingzong said: "This should be the insufficiency in Jiuzhang's arithmetic!"

Chen Ying nodded and said: "Mr. Xu's words are correct. This "-" is a symbol used by big cannibals to indicate 'subtraction' or 'deficiency', which is what Mr. Xu called 'deficiency'!"

"Then this cross—oh, it's a symbol very similar to the Chinese character cross—must be the symbol that represents the meaning of 'Yin' or 'Increase' in Chinese calculation?" Xu Jingzong said happily.

"Exactly—!" Chen Ying nodded: "This symbol is called a 'plus sign', which means 'increase' or 'increase'; the word 'one' is called a 'minus sign' or a 'minus sign'." ', to subtract, to be negative, to be deficient, and to be deficient. Therefore, adding such a character '-' in front of a single Dashi number represents "how much is deficient" or "how much is deficient" in Chinese characters. ' means that numbers with a negative sign in front of this type are collectively referred to as 'negative numbers', while those numbers without such a sign in front of them are called 'positive numbers'..."

Chen Ying saw Xu Jingzong, the future Prime Minister of the Great Tang Dynasty, respecting him like a primary school student, and Chen Ying couldn't say how happy he was.

However, Chen Ying thought to himself: "If you don't go to Lingzhou to be the general manager of soldiers and horses, why don't you open a school of mathematics in Chang'an to teach mathematics, and then the entire household department and industry department of the Tang Dynasty will be full of your own students. It is also a very fulfilling thing that all the bookkeepers in the world who do business and settle accounts all worship themselves as their teachers.

However, what surprised Chen Ying was that Xu Jingzong suddenly knelt down respectfully towards Chen Ying. When Chen Ying was caught off guard, Xu Jingzong kowtowed three times in a row. Not only Chen Ying felt inexplicable, but even Lan Er felt Incredible.

The etiquette system in the Tang Dynasty was quite loose, not to mention seeing Chen Ying, a superior, even the emperor did not need to kowtow.

Chen Ying stood there for a while, then suddenly woke up as if awakened from a dream, he quickly helped Xu Jingzong up and said, "Mr. Xu, this is..."

Xu Jingzong said: "Jingzong is willing to be driven by Lord Hou!"

……

The political system in ancient China was actually very advanced even in the world.Both Western capitalist democracy and China's socialist system are actually relatively democratic.

However, this relatively democratic political system had been formed in China as early as the Qin and Han Dynasties.The evil feudal society is actually relatively democratic.

When the country is faced with important matters and the emperor encounters difficult matters, the emperor will call a meeting of the Sangong Jiuqing and relevant officials to discuss solutions, and the final decision still belongs to the emperor.

The content of the court meeting is very wide, involving politics, economy, military affairs, culture, etc. The number of people participating in the meeting is determined by the consulting firm.There is a difference between the imperial court meeting and the collective meeting.The emperor listened to the government in the hall, and all the officials met in court as usual. If something happened, the emperor raised it orally, and the current court discussed the dispute, which was called court discussion.

Some matters were not proposed by the emperor in the court meeting, but were "discussed" by a certain range of officials, such as the "Nine Ministers' Meeting" and the "Wang Ministers' Meeting", and then the opinions were presented, which is called a collective discussion.The purpose of holding court meetings or assembly meetings is to benefit the emperor's decision-making.

In fact, that is, the Sangong Jiuqing are the regular visitors to the court meeting, and other officials are only present at the meeting when they are discussing the matter.In the Tang Dynasty, he basically belonged to the servants of the six departments of the three provinces, and occasionally attended by the chief ministers of the 24 divisions.

Let hundreds of officials of all sizes in Beijing and China attend the court meeting every day, that is acting on TV.In fact, in most cases, court councils are small-scale circles.

It was the first time that Chen Ying was notified to participate in the early court, which surprised Chen Ying.Chen Ying, a foreign-related military attache, basically has no chance to attend the court meeting at other times, except that he is eligible to attend the court meeting at the beginning of the year.

Chen Ying was also very apprehensive when he attended the court meeting.He speculated that it might be related to Liu Wenjing's bullets.At the same time, it also indicates that Chen Ying has entered the ranks of important ministers of the country.

　Finally, there is a 24-hour double monthly ticket, please add it to the book list.
