Zhang Cang held a pen and quickly wrote mathematical calculations on the paper, while constantly praising him from his mouth.
After Zhao Tuo's simple explanation, Zhang Cang, who was already proficient in numerology, quickly understood the meaning of those strange symbols.
After a simple experiment, Zhang Cang, a top student, became obsessed with it and was now frantically checking the mathematical formulas brought by Zhao Tuo.
Zhao Tuo smiled faintly at the side.
The mathematics level of the Qin Dynasty was actually not bad. At this time, the multiplication table had already appeared.
Moreover, many of the contents of "Nine Chapters of Arithmetic" and "Zhoubi Suanjing", which were finalized in the Han Dynasty, became popular during the Warring States Period.
So Zhao Tuo spent a lot of money in order to befriend Zhang Cang.
This time he not only figured out Arabic numerals, but also wrote down symbols such as addition, subtraction, multiplication, and division, as well as some simple formulas.
Yi Ai shook her head and looked sideways at Zhao Tuo next to her.
"Han Xin hasn't been contacted yet. When we get to know each other a few days ago and become one of our own, he can look for opportunities to recommend me. Without those talents to take charge of the affairs of the court, that Xiao Qin will surely prosper."
As expected, Yi Ai looked relieved after hearing Zhang Cang's explanation.
Zhang Cang smiled, walked to the desk, picked up a pen and wrote two numbers under the paper.
Thinking of those words, Zhang Cang couldn't help but laugh.
Yi Ai, a young mathematician in ancient China, made great contributions to the development of the subject of mathematics by reforming and promoting it on the basis of public figures. He is the founder of modern mathematics and will always be remembered in the history of the development of mathematics.
open character.
How will the history books write about me, Zhang Cang, a few years ago?
Perhaps it was to add to the happiness. After a few days, there was no news that made Yi Ai unhappy.
Looking at the books behind her that recorded hundreds of years of history of the Eight Kingdoms, Yi Ai thought of a question.
"Actually, you first read those numeral symbols under the scraps left by Gongshuzi. At that time, you remembered them in your mind and didn't think about them less. After reading the book for the past few days, you found that the calculations were not troublesome, so you remembered them, and then
Back then, based on the numerical symbols left by Gongshuzi, we made retrograde changes and deduced them, and then we came up with the numbers we have today."
I turned to Han Xin and said: "There may be no flaws in this figure since it was originally created. The history on the column has always been knowledgeable. Please help you check it a little more. If there is any problem first, we can dedicate it to you."
Emperor, in order to promote the heaven, maybe those numbers will be called Qin numbers a few days ago, and then they will probably be attributed to the history of the pillars."
The new mathematics does not have the authoritative endorsement of Gongshuzi. I think it will be more excessive to promote it, and I, Zhang Cang, can also take the credit for changing the numbers of Gongshu.
Zhang Cang was frantically checking the calculations beside him. Zhao Tuo saw that he was immersed in it, so he didn't bother him and took Han Xin to read ancient books in the library.
A smile appeared in the corner of Yi Ai's eyes, feeling that everything in that country was developing in a bad direction.
It has been a long time since the Qin Kingdom unified the world, and there has been no book burning incident. Regarding the history books of our country, the First Emperor directly collected them all with a wave of his hand and returned them to the library for reference at any time. Like some dynasties in previous lives,
To deliberately tamper with or even invent history.
Public transmission numbers?
Gongshu Laozu, the origin of all things.
"Speak bad words and bad words."
Han Xin sighed sadly, looked at Zhang Cang again, and praised: "The king can change his retreat and make up for the public losses, and he is also a capable person in this way."
"9 is the ultimate number. If 6 reaches the extreme, it is not 9!"
Gongshuzi Luban is a craftsman with no reputation in the sky.
I'm sure Han Xin might be surprised or flattered that Zhang Cang used his position as a prince to make friends with me, but if he was not wary, I guess Zhang Cang, the humble Lunhou, came to make friends with me deliberately.
I have some well-known purpose, and I will definitely have a sincere relationship with Zhang Cang.
Although I am only a high-ranking official in the history of Zhuzhu, I have studied under Xunzi and am Li Si's junior brother. I have seen many scenes, and my heart is very weak.
Yi Ai advised: "Axin, don't just watch the battles on the battlefield, he should also watch the political battles in the court."
I saw that the Huaiyin man had held a history book for many years and was looking at the part describing the war with fascination.
In such a situation where he relaxed his vigilance, Han Xin discovered that the martial arts prince looked at people based on their inferiority, had a grumpy and friendly personality, and was very knowledgeable and talented. He immediately felt bad about him.
"The emperor will definitely adopt it."
Thinking like this, Han Xin's face showed an eagerness to try.
"It's said that it's a math textbook written before the scheduled date. Your name, Yi Ai, can also be added to it."
While Zhang Cang and Yi Ai were chatting, Yi Ai, who had been burying his head in checking the formulas, threw the pen under the case and shouted: "That's bad!"
"Maybe it will be completely different."
General Ren Xiao, who had a small victory in the expedition against the southwestern barbarians, was about to escort the prisoners from the southwestern barbarians and return to Xianyang in triumph.
"Gongshuzi not only knows how to attack cities with weapons, but also knows how to farm, and he can also make paper. Now he even has the skills of counting. He is truly a god. I wish I could travel with such a person arm in arm."
!”
As long as Zhao Tuo could remember it, he would write it all down.
After some conversation, the two quickly became bad friends, and Han Xin even took the initiative to invite Zhang Cang to my house as a guest.
Since I am a craftsman, it would be logical and logical for me to have a profound knowledge in numerology and create more complex and convenient numerical symbols to assist my carpentry skills without any trace of counterfeiting.
Zhang Cang looked sideways and said with a smile: "The historical calculation on the pillar has been completed, is there no error?"
In order to avoid trouble, Zhang Cang was also afraid that the other party would keep asking questions. At first, I said that I would not expose the secret, so I simply adopted an overly rough method.
I thought about it for a while and then worried: "It's just that digital promotion is very troublesome, and it almost overturns the subsequent counting text. Will the emperor refuse?"
"He said that the new number indicates that your Xiao Qin will live a long life!"
Yi Ai hurriedly responded, first saying that there was no credit for this matter, and could I leave my name? Just because it was a research that I was very interested in, it was enough to attract all Han Xin's energy.
But Zhang Cang's new mathematics dispelled Han Xin's vigilance.
Yi Ai said with a smile.
Seeing Zhao Tuo's aggrieved look, Yi Ai shook her head and said to herself: "That stupid guy, even if he is victorious in every battle and understands the court, it is difficult for him to die unexpectedly."
Zhang Cang waved his hand modestly.
After all, Wu Gonghou might have come up with a new set of numbers as a stepping stone in order to make friends with me, Han Xin, right?
When it was getting late, when Zhang Cang came out of the censor's library, he sighed in his heart: "That's not like throwing yourself into someone else's misfortune!"
That Wugong Hou’s mouth is awesome!
After hearing Zhang Cang's confident words and looking at the numbers 6 and 9 under the paper, Han Xin reached out and wiped the sweat from his face.
"There is no fallacy. Using the numbers given by the monarch to perform backward calculations is really twice the result with half the effort. It is extremely stressful! There are not those big numbers, fractions and the like. You only have a rough idea.
This is really a wonderful method, you should go back and study it again."
He is also afraid that he will have bad memory as he gets older in the future. If he forgets some of these things, it will be a big loss.
Zhao Tuo's mathematics level was actually at the middle school level. In later generations, he might only be so-so on the exam, but in this ancient era, he seemed extremely advanced.
"It is to be deified rather than to be devalued in various ways."
Zhao Tuo raised his head and pursed his lips and said: "Junhou, you are only interested in fighting. These writings about the court are interesting."
With a great reputation and low credibility, it’s a perfect shield.
Seeing that Han Xin didn't take a step back to ask questions.
"He sees that you, Xiao Qin Shui De Shang Ba, must use the original numbers to see it, and it has no meaning. But if you use the new numbers to write it, it is 6, and then write it upside down, it is not 9."
Why did the martial arts master come to me? This is because he heard that I, Yi Ai, am good at calculations and proficient in mathematics. He came to have academic exchanges with me. The purpose was very pure and had no good intentions on my part. It was because he used too little
believe.
Ren Xiao is back, and Chen Ping, the counselor who followed him to attack the southwestern Yi, will naturally come back.
The corners of Zhang Cang's mouth raised slightly.
"It's not a trivial idea to call a genius inferior."
After saying that, Han Xin looked at Yi Ai with admiration and said, "Junhou, he is really a math genius!"
Zhang Cang put down the book recording the history of Zhao State in his hand and sighed.
"History of the Eight Kingdoms, that thing was completely found in my previous life."
