readx;?Yes, if you want to slap your face, you have to be thorough, you have to give a special paralyzing clean-up at one time, don't be okay for a while, and you have to find me to solve the problem, does Lao Tzu have a lot of time?

If you want to do it, this time you won't dare to preface math problems in front of your grandfather in the future. Pen, fun, pavilion www. biquge。 info

Hearing that Zhu Changyuan was going to come up with a math problem, even Xia Congliang, who had already returned to his seat to prepare for work, became interested, stood up again from his seat, and ran back and said, "Lord Zhu can also come up with the problem, and he still came out of the nine chapters of arithmetic?" ”

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

Of course, as the initiator of this incident, Liu Yunzhou could not retreat, and there was no reason to retreat.

A military attache who fought in the border field has solved the problem twice in a row, and now he has come up with a problem for you, an expert, who is not to accept the offer, is to retreat, to retreat is to admit defeat, to admit defeat is to admit intimidation, and after admitting instigation, he will not be able to mix up in the yamen of the Ministry of Industry.

There is another reason, Liu Yunzhou himself is also a poor classic, and he is very enthusiastic about the problems of mathematics in the past and present, and he is very interested in it.

Zhu Changyuan said that he wanted to make a question, and his interest came, and he said, "Lord Zhu, please ask for a question." "I thought that even if it was the most difficult math problem in the world, with a little study, it would be a big deal to check those ancient books, and there would always be a way to solve it.

However, Zhu Changyuan disappointed him, because Lao Zhu's question this time was not a new question at all, but he gave Liu Yunzhou the same thing about the subject just now.

The question is still the long-range and wide area question, but Zhu Changyuan changed the two numbers in it, so that the difficulty of this question has risen sharply, although the difficulty of modern people seems to have not changed in the slightest, but as an ancient person, the difficulty of this question is enough to make them hurt for centuries.

Zhu Changyuan said: "I'll write it out." ”

Picking up the brush, it was stained with black black ink, and wrote on the paper: Naota accumulates seven steps, but the cloud is not as wide as four steps long. Q: How many steps are wide and long?

The writing is crooked and almost unreadable, and although it is written in traditional characters, it looks almost the same as the writing of a three-year-old child who has just learned calligraphy.

Unsightly. It's ugly to die.

This made the contempt for him of the well-read people in his place even worse.

Zhu Changyuan's question was almost unchanged, except that the eight hundred and sixty-four on the scroll were changed to seven, and the twelve were changed to four.

It is also a problem of a quadratic equation, which is very simple to solve with a quadratic equation. The answer is that the length is 2√11 (√ is the root number), and naturally, the width is 2√11-4

However, this is a problem bigger than the sky for the ancient people of the ordinary world. Because the ancient calculation of one-dimensional quadratic equations in parallel worlds can almost only be to integers, and there are decimals. Because during the Ming Dynasty, there was no universal root-finding formula for a universal one-dimensional quadratic equation in the East.

The writing is ugly, ridiculed, and despised for it. It's up to you to finish the matter.

Liu Yunzhou looked at the question and stared at it for a full minute, and his face suddenly became more ugly than the words written by Zhu Changyuan.

"This, this!" Liu Yunzhou's face was a little red, and he looked at Zhu Changyuan and forcibly argued, "Lord Zhu, your question is wrong, this can't be answered." ”

"Fart." Zhu Changyuan directly burst into foul language, and said: "If you can't solve it, you can't solve it, if you have to say that my question is wrong, can you find a better reason?" ”

Liu Yunzhou said: "According to your question." The smallest number should be one and five, and the product of one and five straight fields is five, less than seven, and naturally leans upward. Then the pairarithmic number that is greater than one and five should be twenty-six, but the product of two-six straight fields is twelve, which is already beyond seven. This, that's the impossible question. ”

Zhu Changyuan also secretly admired this guy, and he really saw the key to this question with the substitution method, and reminded: "Lord Liu." You're not right. Is there no number between one-five and two-six? ”

"Nope!" Liu Yunzhou said categorically.

Zhu Changyuan was also drunk, it stands to reason that the concept of decimal had appeared before the Ming Dynasty, but Zhu Changyuan didn't understand what the ancients called it, it was impossible to call it a decimal like a modern one, so he had to meditate, and then said: "Lord Liu, there are some, for example, there is a number, which is larger than one, but smaller than two." ”

Liu Yunzhou listened to Zhu Changyuan's words, and his face turned pale suddenly, of course he knew the concept of decimals, but when it came to this part, the calculation was extremely troublesome, and even he couldn't figure it out himself, so he wanted to find ways to avoid it, and now through Zhu Changyuan's prompt, he finally couldn't avoid it, and said gloomily: "What Lord Zhu said is a millimeter?" ”

Zhu Changyuan didn't know what the name of decimal in ancient China was, but in the parallel world, it was a millimeter. (Math Emperor sprays me, I'm a parallel world, and I'm in charge of my world.) ）

"Yes, it's a fraction of a second. This question is not difficult, and the numbers in this question can be changed millions of times. After Zhu Changyuan finished with a smile, he handed the crooked number question written in his hand to Liu Yunzhou, and said: "I am a magnanimous person, I don't require you to have my level, give me the answer now, give you three days, and I will obey you if you solve it." ”

Liu Yunzhou didn't pick it up, but finally gritted his teeth and took the rice paper into his hand, and returned to his seat with a flushed face.

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

But there are some millimeters in this question, and it is very troublesome to calculate, even if it is used by the method of coercion, it may not be able to be calculated in three days.

The wisdom of the ancients was free, and the so-called method of coercion was to try by counting a number, of course, not blindly, but to try it regularly and closely, and one day we could try to find the answer.

Seeing this situation, the deputies of the camp were all gone.

Zhu Changyuan finished pretending to be finished, and found a sad fact, the dog had no intention of leaving, and still had no place to sit.

Mom, do you want to go to Xue Lianqian to talk? This is the top boss, so it's good to let him help put some pressure.

Just as he was about to walk out of the door, he met a guy wearing a cyan official mansion, who was hurrying towards the yamen, and almost collided with Zhu Changyuan.

glanced at Zhu Changyuan, didn't ask too much, and shouted to the Qing Officials: "Liu Yunzhou, and Xia Congliang, you two hurry up and go to Balcony Mountain to see, how is the foundation over there?" Just now, the Wen Pavilion Department spoke, if the foundation is not leveled within three days, our Ministry of Engineering is to ask! ”

"Yes, Master Li!"

Master Li is Li Ji, a member of the Ministry of Works.

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

"Uh, who is this, Zhu Changyuan?" Li Ji squinted and asked.

"The next official is Zhu Changyuan, and he has seen Master Li."

"Well, okay, you're just right, the courtyard of the East Palace is overgrown with weeds, and I haven't sent someone to clear it for a long time, so you can take someone to the East Palace to pull weeds." The first time they met, before they had time to say a few words of greeting, Zhu Changyuan was sent by Li Jifa to the East Palace to pull weeds.

Pull the weeds, pull the weeds!

your father, Lao Tzu is here to be an official, is he here to pull weeds?

Zhu Changyuan was also drunk, it seems that he, a military general who came from the border pass, is really an isolated alternative in a group of civil servants. (To be continued.) )
