Take a plane to the Ming Dynasty

Chapter 137
That's right, if you want to slap your face, you have to be thorough, and you have to clean up the paralyzed one at once. Don't ask me to solve the problem after you have nothing to do. I have a lot of time?
If you want to do it, this time it will make you dare not ask math problems in front of grandpa in the future.

Hearing that Zhu Changyuan was going to come up with math problems, even Xia Congliang, who had already returned to his seat to prepare for work, became interested, stood up again from his seat, ran back and said, "Master Zhu can also come up with problems, you can do it yourself. Or is it from Nine Chapters of Arithmetic?"

Most of the math problems of the ancients came from such a few poor books, and "Nine Chapters on Arithmetic" is one of them.

Of course, as the instigator of this incident, it is impossible for Liu Yunzhou to retreat, and there is no reason to retreat.

A military officer who was fighting in the border fields solved the problem twice in a row, and now he turns the problem to you, an expert. If you don’t accept the trick, you will shrink back. Can't get up.

There is another reason. Liu Yunzhou himself is also a person with a lot of classics, and he is very enthusiastic about those difficult problems of numerology throughout the ages. Anyway, he is very interested.

Zhu Changyuan said that he was going to come up with a question, and his interest came up. He said: "Master Zhu, please come up with a question." He thought that even if it is the most difficult math problem in the world, he only needs to study a little bit, and at worst, he will look up those ancient books. There is a way out.

However, Zhu Changyuan disappointed him, because the question that Lao Zhu asked this time was not a new question at all, but he responded to Liu Yunzhou with the same theme just now.

The problem is still the area problem with long range and wide range, but Zhu Changyuan changed two numbers in it, making the difficulty of this problem rise linearly. Although modern people seem to have no change in difficulty, as an ancient person, the problem of this problem Difficult enough to make their ass hurt for centuries.

Zhu Changyuan said: "I'd better write it down."

Picking up a brush, it was stained with black ink, and wrote on the paper: Naota has seven steps, but the width of the cloud is not as long as four steps, and how many steps are each in width and length?

The writing is so crooked that it is almost impossible to read. Although it is also written in traditional characters, it looks almost the same as that written by a three-year-old child who has just learned brush calligraphy.

Ugly, ugly as hell.

This added another level of contempt for him by all the well-read people.

Zhu Changyuan's question is almost unchanged, except that 860 four on the scroll is changed to seven, and twelve is changed to four.

It is also a question of a quadratic equation in one variable. It is very simple to solve this problem with a quadratic equation in one variable. The answer is that the length is 2+√11 (√ is the root sign). Naturally, the width is 2+√11-4.
However, for the ancient people in the normal world, this is a problem bigger than the sky.Because the ancient calculations of quadratic equations in one yuan in the parallel world can only reach integers, and it will stop when there are decimals.Because in the Ming Dynasty, there was no universal formula for finding the root of a quadratic equation in one variable in the East.

If the handwriting is ugly, it's ugly, whether it's ridicule or contempt, you have to read the title when you're done.

Liu Yunzhou read the question, stared at it for a full minute, and his face suddenly became uglier than Zhu Changyuan's writing.

"This, this!" Liu Yunzhou's face was a little red, and he watched Zhu Changyuan forcefully argue, "Your question is wrong, Mr. Zhu, and it cannot be answered."

"Fart." Zhu Changyuan swears directly, and said: "If you can't solve it, you can't solve it. If you insist on saying that my question is wrong, can you find a better reason?"

Liu Yunzhou said: "According to your question, the smallest number should be [-] and [-]. If [-] is equal to [-], if it is less than [-], it will naturally go up. Then a pair of numbers greater than [-] and [-] should be [-]." , but the accumulation of two and six straight fields is twelve, which is already more than seven. This, this is an impossible question."

Zhu Changyuan also secretly admired this guy. Using the substitution method, he saw the key point of this question at once, and reminded: "Master Liu, what you said is wrong. Could it be that there are no numbers between one five and two six?"

"No!" Liu Yunzhou said firmly.

Zhu Changyuan was also drunk. Logically speaking, the concept of decimals appeared long before the dynasty, but Zhu Changyuan didn't understand how the ancients called them. It couldn't be called decimals like modern times. Yes, for example, if there is a number, it is larger than one, but smaller than two."

After hearing Zhu Changyuan's words, Liu Yunzhou turned pale. Of course he knew the concept of decimals, but when it comes to this one, the calculation is extremely troublesome, and even he himself doesn't quite understand it, so he wants to try to avoid it. Now, through Zhu Changyuan's reminder , he finally avoided the inevitable, and said dejectedly: "Master Zhu is talking about the number?"

Zhu Changyuan didn't know what the name for decimals was in ancient China, but in the parallel world it was the number of a few millimeters. (Mathematics emperor, don't spray me, I am a parallel world, and I am the master of my world.)
"Yes, it's just a fraction of a millimetre. This question is not difficult, and the numbers in this question can be changed millions of times." Zhu Changyuan finished speaking with a smile, and handed the crooked number question written in his hand to Liu Yunzhou, and then Said: "I am a generous person. I don't require you to have my level. Give me the answer now. I will give you three days to solve it and I will obey you."

Liu Yunzhou either accepted it or not, and finally gritted his teeth and took the rice paper in his hand, blushing and returned to his seat.

Even if it took three days to solve it, it would still be inferior.

But this question actually contains a few centimetres, and it is very troublesome to calculate. Even if you use the method of pinching, you may not be able to complete the calculation in three days.

The ancients were free from the wisdom of the ancients. The so-called method of coercion is to try one by one. Of course, it is not a blind test, but a regular approach that is getting closer and closer. One day, the answer will be found.

Seeing this situation, the principals and deputies of the camp all left in desperation.

After Zhu Changyuan had finished pretending, he discovered a sad fact that Gou Bi Ma Qing had no intention of leaving, and still had no place to sit.

Damn, do you want to talk to Xue Lianqian?This guy is the immediate boss, so it's good to ask him to help put pressure on him.

Just as he was about to walk out the door, he bumped into a guy wearing a blue official mansion, who was walking towards the yamen in a hurry, and almost bumped into Zhu Changyuan.

Glancing at Zhu Changyuan, without asking any further questions, he shouted to the Qing Dynasty Officials Department: "Liu Yunzhou, and Xia Congliang, you two hurry up to Yangyang Mountain to see how the foundation is being treated over there? The Ministry of Wenge just spoke , if the foundation is not leveled within three days, we will ask the Ministry of Industry!"

"Yes, Lord Li!"

Mr. Li is Li Ji, a member of the Ministry of Industry.

The last time Zhu Changyuan came to report to him, he was on the sidelines.

"Uh, this is Zhu Changyuan?" Li Ji asked with narrowed eyes.

"The next official is Zhu Changyuan, who has met Mr. Li."

"Well, good, it's just right that you are here. Weeds are overgrown in the courtyard of the East Palace. It has been a long time since someone has been cleared. You can take someone to pull the weeds in the East Palace." The first time we met, Zhu Changyuan hadn't had time to exchange greetings. Sent to the East Palace to pull weeds.

Pull the weeds, pull the weeds!
Fuck your dad, I came to be an official, did I come to pull weeds?

Zhu Changyuan was also drunk. It seemed that he, a general who came from the border, was really isolated among a group of civil servants.
