readx;? Chen Xixian, the supervisor of Longshan Temple, made a gesture early on, this is the territory of the Empress Dowager Yang, and Yang Jing is not welcome, and even if you want to enter the mountain gate, you need to go through the test of breaking through.

His martial arts may not be good, but he is obsessed with arithmetic, so he used arithmetic problems to embarrass Yang Jing, but what is surprising is that Yang Jing successfully solved the problem twice in a row, which made Chen Xixian lose face!

Chen Xixian, who was unwilling, wanted to save some face, so he made an appointment with Yang Jing to bet on the third question, at this time, everyone was in the spotlight, waiting for him to come up with the question, Chen Xixian coughed lightly, and walked to the edge of the bamboo, and said to Yang Jing.

"There is a bamboo field that is one zhang high, and the end is folded to the ground, and the bamboo is still three feet, and the bamboo is still high?"

Chen Xixian has a characteristic of writing questions, he likes to make impromptu ideas, and he uses whatever he sees, or uses topics related to his life, which shows that he has extremely deep research attainments in mathematics, and has reached the level of ease.

The meaning of his question is that there is a bamboo that is one zhang long, and it breaks off in the middle, so that its end touches the ground, and the end is three feet from the root of the bamboo, and asks how tall the bamboo is.

Yang Jing groaned slightly, and then smiled, because at this time, the bamboo just formed a right-angled triangle, knowing the bottom edge, finding the right-angled edge, only need to use the Pythagorean theorem to solve it!

The Pythagorean theorem can't be calculated by heart, so Yang Jing broke off a bamboo branch and wrote the equation on the ground.

In the first two questions, Yang Jing is just mental arithmetic, Chen Xixian can't know Yang Jing's calculation process, and now seeing that Yang Jing is finally going to do it, Chen Xixian is also excited to the extreme!

Because if Yang Jing can't do anything, he can only admit defeat, but Yang Jing has no such signs, Yang Jing's calmness and calmness, as if telling him Chen Xixian, this question also can't stump Yang Jing!

At this time, Chen Xixian was more curious than jealous of Yang Jing, he was a person who was extremely obsessed with arithmetic, and when he saw Yang Jing write down the equation, he was completely stunned!

Because he had never seen these runes, Yang Jing wrote down the equations smoothly, and then calculated them one after another, and he was focused, like a god hidden in the world, writing a line of heavenly books!

Not only Chen Xixian, but also Chen Mi and Feng Ruochen and others were also dumbfounded!

They have never seen these words and symbols, for these superstitious ancient people, especially those in the Taoist sect, it should be shocking to see a person who understands the "Book of Heaven"!

After a short period of sluggishness, the disciples behind the mountain gate ran back quickly, and after a while, several old men appeared vaguely in the crowd!

Yang Jing also expected early on what kind of effect he would have when he wrote these equations, and since he had decided to use these competitions as a way to win people's hearts, he must establish his prestige in the process!

Yang Jing knows very well that the process of solving the equation in this line is definitely more shocking than his defeating a strong opponent by force!

Because this is an era of believing in ghosts and gods, this is an era that can treat Bai Yu Toad Ge Changgeng as a living immortal, and a person like Yang Jing who can get the answer to the problem without counting chips and abacus beads should be a god who is "born to know"!

Now that Yang Jing has written these words and symbols that no one can understand, and all their cognitive categories are comparable, they are comparable to the existence of "heavenly books", how can these Taoist disciples not be shocked!

Yang Jing calculated all the way and quickly came up with the result.

He raised his head and said to Chen Xixian: "Zhuyuan is one zhang high, the end is folded to the ground, three feet to the original, and four feet five or five feet high, Chen Guanzhu, I don't know if this official is right?"

Chen Xixian couldn't help but be shocked, although this question seemed to be done casually, but in fact, he had already calculated the answer many times, but he didn't expect Yang Jing to really calculate the answer!

What's even more surprising is that Yang Jing's answer is more accurate than the answer he came up with!

Yang Jing used the equation to calculate 455 feet, but considering that there was no such concept as a decimal point in ancient times, Yang Jing was not easy to use.

In ancient times, the units of length measurement were zhang, ruler, and inch, which were four feet five or five, and how many inches should be converted into later, but Yang Jing was too lazy to convert, so he directly said a number of four feet five or five.

But obviously, Chen Xixian understands very well what an accurate concept of four feet five five is!

While Chen Xixian was still muttering in disbelief, lying on the ground, almost touching the ground, staring at the equation, Yi Ji shouted at Yang Jing.

"Don't think that if you write some ghost talismans, you can get by, my uncle is a master of mathematics, others don't recognize it, he will definitely be able to see through your tricks!"

Yi Ji has also learned hundreds of skills since she was a child, so she naturally knows very well that Yang Jing has real skills, but her uncle Chen Xixian originally wanted to rely on the third question to save face, but he didn't expect Yang Jing to still calculate it with an understatement!

Chen Xixian can bear it, but she Yi Ji can't bear it, because she thought that Yang Jing was nothing great from the beginning, and now Yang Jing has shown amazing talent, which is tantamount to proving that she Yi Ji is blind!

Yang Jing looked at this arrogant and competitive little Dao Gu, but kept smiling, because he knew that Chen Xixian was a knowledgeable person, and he would definitely treat the equation as a treasure from the sky!

If not, hearing that Yi Ji provoked Yang Jing, Chen Xixian immediately stood up and said to Yi Ji: "Don't be rude to Lord Yang!"

Yi Ji saw that there was no blame in Uncle Shi's eyes, but just a fiery thirst, just like the last time he got a unique book of mathematics, Yi Ji knew that Uncle Shi was going to completely lose to Yang Jing, a dog official!

"Hmph, uncle, if you don't help me, Yi Ji will find his uncle!" Yi Ji's eyes were full of grievances, so she ran behind the mountain gate, thinking that she was going to pick up that uncle again, and wanted to continue to target Yang Jing and save all this!

Chen Xixian saw that Yi Ji turned his head and left, and he also smiled helplessly.

He has studied mathematics for many years, and although he can't read the equation, he can see that this is by no means nonsense, because he sees the law in it, and this law is the core of the Pythagorean theorem!

He was not amazed by the Pythagorean theorem, but by the characters used by Yang Jing, which can be simplified and decayed into magic!

As a master of mathematics, he naturally knows that the Pythagorean theorem was explained to Zhou Gong by using the three specific numbers of three, four and five.

Although this is only a special case, in a slightly later period, Chen Zi, a descendant of Zhou Gong, clearly summarized the Pythagorean theorem, that is, the so-called "Pythagorean multiplies each other, and divides it to get evil." ”

The Pythagorean theorem is also expressed in the "Commentary on the Sutra of Zhou Ji" of the Three Kingdoms: "The Pythagorean theorem is multiplied by each other, and it is combined, which is a string, and the square is divided, that is, the string." ”

Later, in mathematical works such as "Nine Chapters of Arithmetic", there were also expositions on the Pythagorean theorem.

Therefore, Chen Xixian knows the Pythagorean theorem, and can see the Pythagorean theorem from Yang Jing's equation, and he is amazed by the equation used by Yang Jing!

Because this has never been done before!

The numbers and symbols, as well as the operations, are more intuitive than the text description, and they are so simple that they are easy to understand at a glance!

In Chen Xixian's eyes, these numbers and symbols are indeed like heavenly books, which have never been seen, but these heavenly books can express the complex number in the simplest way, which is definitely beyond the times!

Chen Xixian suppressed the surprise and impulse in his heart, and said to Yang Jing: "Mr. Yang, it was the old man who offended him earlier, and the old man was convinced, but... I just don't know what these algorithms are, sir..."

Speaking of this, Chen Xixian was also a little surprised, after all, he is very old, and Yang Jing is just a young man in his twenties, from Lord Yang to Mr. Yang, the change in title is enough to prove what a huge shock Yang Jing's equation has brought to Chen Xixian!

Because in ancient times, the word "sir" was not something that could be used casually, and not everyone could be worthy of it!

After all, Chen Xixian is a prison and represents the interests of Longshanguan, he is the first line of defense to prevent Yang Jing from launching an investigation in Longshanguan, but unfortunately he did not complete the task, or he has tried his best, but he has not been able to achieve the desired effect.

Now, his mission has ended, but he can't let go of this opportunity, because in Yang Jing's body, there is something new that can lead the number of arts forward for hundreds of years, that is, these "heavenly books" written by Yang Jing on the ground!

Yang Jing naturally knew what Chen Xixian wanted, this old Taoist priest who was entangled in mundane affairs and couldn't focus on cultivation, obsessed with mathematics, he was just like Du Kefeng and others, they all hoped that they could only do one thing in their lives, and only do one thing well in their lives, they were people who pursued the limits in their own fields!

For these equations, Yang Jing does not mind leaving them to this era, if he can promote the education or cultural progress of this era, Yang Jing is naturally happy to see it.

Chen Xixian should have regarded Yang Jing as an enemy, but he changed his attitude, which can be seen from this point that Chen Xixian is really obsessed with mathematics, and not has other plans.

For this kind of people who purely pursue the ultimate in skills, Yang Jing has always been very encouraging, because it is these people who are promoting the progress of the times, and they are the cornerstone of erecting the ancient science and technology culture edifice!

Looking at Chen Xixian, who was full of urgency, Yang Jing smiled at him and said, "This is a complete set of mathematical theories, if Chen Guanzhu is really interested, we can talk about it later." ”

When Chen Xixian heard Yang Jing say this, his heart was suddenly overjoyed, and he bent down deeply towards Yang Jing and said: "Mr. Yang is humble and humble like a valley, and the old man will thank Mr. first!"

Chen Xixian's change in attitude is surprising, but it also lets the people around him know how great the value of the arithmetic method used by Yang Jing is, and Chen Xixian is also using his attitude to prove to everyone that Yang Jing does have real skills, and in terms of mathematics, he is indeed more powerful than him, the master!

Although Feng Ruochen couldn't understand it, she also knew the value of this equation, and seeing Chen Xixian's condescending attitude, she knew that Yang Jing was going to be soft-hearted again, so she walked over and erased the equation with her feet!

Yang Jing also couldn't cry or laugh, but she also secretly winked at Feng Ruochen, signaling her to do a good job, because in this way, Chen Xixian could not think about tea and dinner, and it would be more strange to live, so that Chen Xixian could provide more convenience for himself.

Chen Xixian was also annoyed when he saw that Feng Ruochen erased the equation, and he should memorize it first, even if Yang Jing didn't teach him in the future, he would be able to understand it himself.

It's a pity that Yang Jing has never seen these characters, they are too unfamiliar, and they are completely different things, Chen Xixian tries hard to recall, but it is impossible to reproduce them.

He swept away Feng Ruochen, and couldn't help but sigh lightly in his heart, no wonder Feng Ruochen has been following Yang Jing, because she knows Yang Jing too well, she is strong enough, and she will not cause trouble to Yang Jing, and she does not need Yang Jing to provide protection, but can become Yang Jing's most powerful assistant!

Chen Xixian took a breath lightly, and then said to Yang Jing: "One yard to one yard, Mr. Yang's mathematical attainments have indeed convinced Lao Dao, but the next test needs to be continued, so Lao Dao will lead Mr. Yang in." ”

Yang Jing also knows that there is a clear distinction between public and private, and now Chen Xixian has shown respect, which is already a huge gain, which shows that his strategy is right, and this competition should bring extremely significant and important effects and effects to him in controlling Longshan View!

"Then it will be troublesome to watch the Lord. Yang Jing said this, but he was looking forward to the next level!
