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, fractional decimals, and nine-nine multiplication tables are very basic things in the eyes of later generations. If they are placed from the perspective of ancient times, they are all very advanced results. Westerners at the same time were still confused about these things. Force it.

This may be related to the Confucian philosopher Kong Zhongni's designation of "arithmetic" as one of the six arts of gentleman. Most Confucian scholars will study arithmetic. Of course, this does not mean that the ancients realized the importance of mathematics, they just regarded this as a game for training their intelligence. The mainstream opinions in the society still value Confucian classics, poetry and songs, and despise the "trivial tricks" of arithmetic.

Chen Youlan is known as a talented woman, and he has also studied arithmetic with interest. Although it is certainly not as good as Li Xin, it is much higher than most ordinary people. She randomly asked three or five arithmetic problems of addition, subtraction, multiplication and division, restricting Li Xin to do it 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, his fingers flew, and his hands were so fast that he would even bow down to the most powerful keyboard man in future generations. 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?" Although she knows that Li Xin can't do such boring things, she still can't do it rationally. I believe Li Xin's speed in doing the questions. She knows very well that if she is given a count, she can also figure out the answers to these questions, but it is absolutely impossible for Li Xin to be so fast.

Li Xin said that the abacus can be calculated ten times faster than the abacus, which should be a bit exaggerated, but there is no doubt that it is five, six, seven or eight times faster.

Hearing Chen Youlan's suspicion, Li Xin was not angry. This was completely unexpected. If he were changed to Chen Youlan, he would definitely have the same question when he saw such a scene. He smiled frankly and said: "You can check the calculations at will to see if I am wrong."

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

Li Xin originally had two or three calculation chips at home. After trying to play, he found that he couldn't play this thing, so he drew a picture and asked the carpenters to create the first abacus of the Tang Dynasty according to the drawings. With an abacus, he naturally didn't need the abacus, so he let Wang Gui handle it by himself. Fortunately, Wang Gui was a master of the house. He didn't use these counts as firewood, but received it in the corner of the study.

Li Xin asked Runniang to find out who was shelved.

Chen Youlan tried to use arithmetic to calculate three or two problems, and found that the results calculated by Li's credit abacus were exactly the same. So, she didn't bother to forget about the remaining questions.

"Is this abacus invented by His Royal Highness Chu?" Chen Youlan asked with a wry smile. She couldn't imagine that the seemingly delicate young boy beside her could have so many weird ideas in his mind, and that shocking new things appeared endlessly in his hands.

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 say you will call me Brother Li in the future?"

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. At this moment, although she is still wearing men's clothing, her mental state is very different from that at the time. How could she call "Brother Li" so easily.

The air was strangely silent for a moment.

"So, this abacus is also...Li...Is it 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 mouth again, and a strange sense of intimacy suddenly appeared in his heart, as if the distance between Chen Youlan and Chen Youlan was getting closer. There was even a kind of The feeling of being close at hand made my heartbeat speed up unconsciously.

He couldn't help laughing, and didn't irritate 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. He just subconsciously fiddled with the abacus with his hands, and said: "Brother Li, there is such an ingenuity, and he is a masterpiece that can shake the world and earth and earth. When you go out, I don’t know how many accountants and household officials in the world want to thank you for your talents. Maybe you will be respected as the ancestor and let you spread through the ages."

Li Xin rolled his eyes and said, "I don't care about these things. Although I am not the kind of person who cherishes himself with a broom, I don't want to give away all the good things so free, right? Who would do things that are not good? what."

Seeing Li Xin suddenly changed his face, Chen Youlan instantly changed from a wise, peerless genius to a caressing prankster. For a while, he was dumbfounded and had to smile again and again.

The name that many people dream of goes down in history, but in his eyes there is no actual benefit........

Chen Youlan asked with some amusement: "Then how do you want to teach everyone the abacus?"

Li Xin didn't think too much, so he blurted out subconsciously: "If you kiss me, I will dedicate my abacus to your majesty tomorrow, and by the way, I will also take care of the church's stupid household officials."

As soon as the voice fell, he took a breath, regretting it and said: It's over!

These words are undoubtedly Meng Lang, very Meng Lang's kind! Even in later generations, any man who said such things to a girl, being scolded or even slapped, is not considered wronged, let alone in the Tang Dynasty, it is extremely frivolous! Almost without exception, those who can say such things are regarded as prodigal sons.

Chen Youlan will definitely be angry. Li Xin could even imagine her walking away, never ignoring his picture again, her heart seemed to keep sinking in her chest.

Just as Li Xin closed his eyes and hated himself for why he didn't speak through his brain, and why he didn't think about it before speaking, he suddenly felt that his left cheek was touched by something, soft and a little moist. There was a slight temperature, even after it left his cheek, there was still a strange touch on the cheek that was touched.

He opened his eyes as if getting an electric shock, glanced at Chen Youlan next to him in surprise, and subconsciously raised his hand to cover his cheek. Xiao Ling, who had been standing quietly in the room, was covering her eyes with one hand, while covering Runniang's with the other. She muttered something in her mouth and said very, very quietly, "Children can't see. ......Can not watch........"
