Carefree Prince In Tang Dynasty

Although the development of Chinese mathematics in later generations was slightly inferior to that of the West, in fact, ancient Chinese mathematics was in a leading position. Addition, subtraction, multiplication and division, fractions and decimals, ninety-nine multiplication tables, which are very basic in the eyes of later generations, are very advanced achievements from the perspective of ancient times. Westerners at the same time were still confused about these things Forced.

This may have something to do with the Confucian philosopher Kong Zhongni's designation of "arithmetic" as one of the six arts of a gentleman. Most Confucian scholars will study arithmetic to some extent. Of course, this does not mean that the ancients realized the importance of mathematics, they just regarded it as a game to exercise intelligence. The mainstream opinions in society still value Confucian classics, poems and songs, and despise the "trivial tricks" of arithmetic.

Chen Youlan has always been known as a talented woman, and she has also studied arithmetic out of interest. Although she is definitely not as good as Li Xin, she is already much higher than most ordinary people. She casually came up with three or five arithmetic problems of addition, subtraction, multiplication, and division, and Li Xin was limited to solve them within a stick of incense.

Unexpectedly, Li Xin waved his hand and said, "It won't take that long."

After finishing speaking, he picked up the abacus and moved his fingers like flying. The speed of his hands was so fast that even the most powerful keyboard man in the future would be willing to bow down. After a while, he reported the answers one by one.

Chen Youlan was stunned by Li Xin's speed, blinked, and said, "You won't just make up a few answers to fool me, will you?" Although she knew that Li Xin would not do such a boring thing, she still couldn't do it rationally. Believe in Li Xin's speed of solving the questions. She knew very well that she could figure out the answers to these questions if she was given a calculation, but it was absolutely impossible to be as fast as Li Xin.

It should be exaggerated for Li Xin to say that the abacus can calculate ten times faster than the abacus, but there is no doubt that it can be five, six, seven or eight times faster casually.

Hearing that Chen Youlan was suspicious, Li Xin was not angry either. This was completely expected. If it were Chen Youlan, he would definitely have the same doubts when he saw such a scene. He smiled frankly and said, "You can check the calculation casually to see if I have made any mistakes."

Chen Youlan glanced at Li Xin, and finally decided to check the calculation again.

Li Xin had two or three sets of abacus at home. After trying to play with it, he found that he really couldn't handle it, so he drew a picture and asked the carpenters to create the first abacus in Datang according to the blueprint. With the abacus, he naturally didn't need to calculate it, so he let Wang Gui handle it by himself. Fortunately, Wang Gui is a master of the house, so he didn't use these counting chips as firewood, but received them in the corner of the study.

Li Xin asked Runniang to find out the plan that had been put on the shelf.

Chen Youlan tried to calculate two or three questions with calculations, and found that the results calculated by Li Xinxin's calculations were completely consistent. So, she didn't bother to calculate the rest of the questions.

"Is this abacus also invented by His Royal Highness the King of Chu?" Chen Youlan asked with a wry smile. It was really hard for her to imagine that the handsome-looking young man next to her could have so many weird ideas in his mind, and shocking new things just kept emerging in his hands like this.

Is this a genius or a monster?

Unexpectedly, Li Xin didn't answer Chen Youlan's question at all, but smiled and said, "Didn't you agree to call me Brother Li from now on?"

Chen Youlan was stunned.

At that time, she didn't know that Li Xin had seen through her disguise, so she agreed to Li Xin's request as Chen Zijin. Although she is still wearing men's clothing at this moment, her psychological state is very different from that at that time, how can she call "Brother Li" so easily.

There was an eerie silence in the air.

"So, is this abacus also invented by Brother Li?" Chen Youlan blushed and asked again in a very small voice.

Li Xin was just joking about Chen Youlan casually, but Chen Youlan actually changed his mind, and suddenly he felt a strange sense of intimacy, as if the distance between him and Chen Youlan had narrowed a little bit, and there was even a kind of Feeling close at hand, even the heartbeat speeded up unconsciously.

He couldn't help laughing, and didn't provoke Chen Youlan anymore, for fear that she would be too shy.

"I invented it." Li Xin replied.

Chen Youlan was not surprised by this answer, but subconsciously fiddled with the abacus again, saying: "Brother Li is a genius, he has such an ingenious idea, and it can shake the world if he makes it casually. If the abacus is passed on in the future If you go out, there are countless accountants and household officials in the world who would like to thank you for your talent, and maybe they will respect you as a patriarch, and it will be easy for you to be passed down through the ages."

Li Xin rolled his eyes and said, "I don't care about these things. Although I'm not the kind of person who cherishes my own broom, I can't give away all the good things for nothing, right? Who would do something that has no benefit what."

Seeing Li Xin's sudden change of expression, Chen Youlan instantly changed from a peerless genius with extraordinary wisdom to a caring philistine.

How many people dream of being famous in history, in his eyes, it is not as good as a little practical benefit

Chen Youlan asked with some amusement: "Then what are you going to do to teach everyone the abacus?"

Li Xin didn't think too much about it, and subconsciously blurted out: "If you kiss me, I will go and present the abacus to His Majesty tomorrow, and I will also guarantee the church's stupid household officials by the way."

As soon as the words fell, he gasped and said with great regret: It's over!

These words were undoubtedly from Meng Lang, very Meng Lang's kind! Even in later generations, if any man said such things to a girl, it would not be considered unjust to be scolded or even slapped, let alone in the Tang Dynasty, it would be extremely frivolous! People who can say such things, almost without exception, will be regarded as prodigal sons.

Chen Youlan will definitely be angry. Li Xin could even imagine the image of her leaving in a huff and ignoring him ever since, his heart seemed to sink continuously in his chest.

Just as Li Xin was closing his eyes, secretly hating himself for not going through his brain and why he didn't think about it before speaking, he suddenly felt his left cheek was touched by something, it was soft and moist, There was a slight warmth, even after it left his cheek, there was still some kind of wonderful touch left on the touched part of his cheek.

He opened his eyes like an electric shock, looked at Chen Youlan beside him in surprise, and subconsciously raised his hand to cover his cheek. Xiaoling, who had been standing quietly in the room without making a sound, was covering her eyes with one hand, and covering Runniang's with the other hand, muttering something in a very, very low voice: "Children can't see. Can not watch."
