Coincidentally!My name is Liu Bian

Chapter 213 Liu Bian quickly solved the problem
Liu Bian opened his mouth and then closed it again. He was stuck. He didn't know whether to admit it for a moment: This problem involves solving an indefinite equation. It may be difficult for people who are not good at mathematics to understand...

So, here comes the question: Should he, who is only 13 years old, talk nonsense in a nonchalant manner that he is actually good at mathematics and has read "Nine Chapters of Arithmetic"?

Calmly, he said: "This question seems difficult, but I feel familiar, as if I have seen it somewhere... Think about it carefully, isn't this the question in "Nine Chapters of Arithmetic"? Yesterday I also casually flipped through "Nine Chapters of Arithmetic" in the bookcase and happened to remember it!"

As soon as he finished speaking, Zhuge Liang exclaimed: "Brother Bian, you are so awesome! I feel like you can do everything!"

Clenching his hands into fists, Zhuge Liang vowed: "It's decided! From today on, I will also read "Nine Chapters of Arithmetic"!"

Xu Shu stretched out his hand and wanted to stroke Zhuge Liang's head, but Zhuge Liang avoided it and withdrew his hand, Xu Shu also asked: "Do you want to accompany you for my brother?"

"No need!" Zhuge Liang refused firmly.

However, Xu Shu did not follow the routine and said with a smile: "The bookstore is not owned by your family. If you can read it, why can't I read it? - I want to read it too!"

"No!" Zhuge Liang lowered his face and glared at Xu Shu.

Xu Shu was not affected at all!

Xun Yu: "..."

Withdrawing his gaze, Xun Yu looked at his Highness suspiciously, unable to distinguish the truth from the falsehood for a moment.

However, since His Highness can solve the problem, then... Narrowing his eyes, Xun Yu said: "Please allow me to accompany you, okay? - I happen to know a senior disciple of Sir, and I can ask that person to help witness!"

"Really?" Liu Bian made a decision quickly, "We can set off immediately without delay?"

"That's fine." Xun Yu nodded.

Afterwards, Liu Bian, together with Xun Yu, took Cui Yan's recommendation letter and left quickly.

Zhuge Liang and others were left in a mess in the wind.

Zhuge Liang stared at the leaving figures of Liu Bian and Xun Yu, and asked depressedly, "Have we been abandoned by His Highness?"

The corner of Xu Shu's mouth twitched. He had given up correcting Zhuge Liang's misuse of idioms and sighed: "You want to say that without the financial support of His Highness and Mr. Wen Ruo, you will have no money to eat, right?"

Zhuge Liang's ears turned red and he was speechless.

At this time, Cao Ang patted his chest and said coldly: "Your Highness and Sir are not here, how about I treat you?"

Ok? !

Hearing this, all eyes fell on Cao Ang.

Cao Ang shrank his neck and whispered: "It's almost the same as Da Yuan and Er Yuan. I also prepared some money and silk."

Everyone: "..."

Everyone was speechless, but Yuan Tan and Yuan Xi were livid and shouted angrily: "Cao Ang!!"

Cao Ang held his head and whined: "Stop pretending to be poor! I didn't see that His Highness stopped traveling with us in order to save money..."

This is really a sad thing.

When everyone was silent, Liu Bian followed Xun Yu and found the senior disciple.

The senior disciple was in his forties. When he saw Xun Yu coming to visit him with a letter, he quickly expressed his welcome.

After Xun Yu led Liu Bian to the humble residence of the disciple, he was not unambiguous. He immediately explained the reason for his visit and said: "I came to you this time to ask you to be a witness... This son Just after entering the academy, Mr. Zheng assigned another question. Coincidentally, this kid has read "Nine Chapters of Arithmetic" and is not unfamiliar with this question - he can solve the problem and wants to see Mr. Zheng, so I want to ask you for a favor. , please agree?"

Pointing his hand, Xun Yu pointed at Liu Bian.

Liu Bian bowed at the right time, with a respectful attitude.

The Gaozu disciple said: "You have said so, can I refuse?"

Later, the other party brought pen, ink, paper and inkstone and asked Liu Bian to solve the problem in person.

Liu Bian held the pen and wrote a long essay quickly without any hesitation.

That senior disciple and Xun Yu looked at it:
"Analysis and Answers:

Because one hundred dollars buys one hundred chickens, so on average one penny buys one chicken!

There are four chickens in each group: one hen and three chicks, worth four dollars in total!Note: A hen is worth three coins and three chicks are worth one coin, which is exactly the average price of one chicken.

There are seven chickens in each group: one rooster and six chicks.It's worth seven dollars!Note: A rooster is worth five cents, three chicks are worth one penny, and six chicks are worth two cents, which is exactly the average price of one penny for a chicken.

No matter how many large groups and how many small groups a hundred chickens can be divided into, each penny will buy one chicken on average.One hundred chickens need to be considered how many large groups and how many small groups can be divided into!
Through analysis and testing, we can find the following three situations:

The first type: Divide into four large groups and eighteen small groups!

There are roosters in four groups: one multiplied by four equals four

The number of chicks in the four large groups is: six times four equals 24. The number of hens in the eighteen group is: one times eighteen equals eighteen.

There are chicks in the eighteen groups: three times eighteen equals 54.

In this case, there are four roosters, eighteen hens, and chicks (24 plus 54 equals 78).

Second type: divided into eight large groups and eleven small groups.

There are roosters in eight large groups: one times eight equals eight.

Chickens in eight groups: six times eight equals 48

There are eleven hens in the eleven groups: one times eleven equals eleven.

There are 33 chicks in the eleven groups: three times eleven equals [-]
In this case, there are eight roosters, eleven hens, and chicks (48 plus 33 equals 81).

The third type: divided into twelve large groups and four small groups.

There are roosters in the twelve large groups: one times twelve equals twelve.

The number of chicks in the twelve large groups is: six times twelve equals 72

There are four hens in the group: one times four equals four

There are four chicks in the group: three times four equals twelve.
In this case, there are twelve roosters, four hens, and chicks (72 plus twelve equals 84).

Therefore, there are three possibilities for this question:
Buy four roosters, eighteen hens, and 78 chicks;

Or buy eight roosters, eleven hens, and 81 chicks;
Or buy twelve roosters, four hens, and 84 chicks. 』

A flash of surprise flashed in Xun Yu's eyes, and he watched in surprise as his Highness wrote furiously——

Xun Yu can guarantee: with His Highness’s speed, His Highness should be the No. 1 student to solve this problem, there is no doubt about it!
... With a bang, Liu Bian finally finished writing the solution to the problem. He felt light all over, raised his head and asked:

"How?—right?"

The senior disciple stared straight at Liu Bian's answer, and replied without blinking: "Yes! Yes, yes! That's so right!"

After rubbing his hands, the senior disciple was very excited and said excitedly: "Do you need to see the teacher? - I will contact the teacher immediately!"

After that, the Gaozu disciple ran away happily.

Liu Bian and Xun Yu were left looking at each other in confusion.

Before Mr. Zheng Xuan arrived, Xun Yu took the lead and said, "Sir, did you really read this in the book?"

Liu Bian paused for a moment, since he couldn't tell Xun Yu the truth: He couldn't say, who made me a time traveler, just because I happened to know that this problem needs to be solved using an indefinite equation to solve it?
Shivering, Liu Bian waved his hand and said, "Don't worry about the details. The point is that I figured it out... Don't forget that we can only study in the academy for half a month! During this period, I want to invite Mr. Zheng for something."

With a chill in his heart, Xun Yu recalled the mission of his Royal Highness coming to the "Beihai Academy" after traveling thousands of miles... After calming down, Xun Yu said: "Then we will wait here for the arrival of the master? — Young Master, are you hungry?" Is it done?"

Coming here in such a hurry, His Highness didn't even have lunch!

It's okay if you don't say it, but if you say it... Liu Bian touched his stomach, and it made a growling sound in time - Liu Bian said without changing his expression: "I'm not hungry! Where are you, Wen Ruo? Do you need to eat?" A trip to the room?"

"No need." Xun Yu shook his head, "I want to be with you, Your Highness..."

As soon as he finished speaking, Liu Bian reached out and covered Xun Yu's mouth.

"Why are you confused again?" Liu Bian looked around and corrected, "Call me Young Master!"

Fortunately there was no one around, otherwise...

Before Xun Yu could admit his mistake, Liu Bian suddenly heard footsteps coming from outside the door.

Then, the voice of Zheng Xuan, who had just said goodbye, rang out:

"He Bian, have you solved the problem?"

Liu Bian was stunned for a moment and went out looking for fame. He saw Zheng Xuan surrounded by several senior disciples, rushing over in a hurry.

"Sir, please sit down." Liu Bian and Xun Yu stepped forward and saluted Zheng Xuan.

Zheng Xuan did not sit down, but asked: "Where is your answer? Let me take a look!"

Liu Bian complied and handed the answer question to Zheng Xuan to look at.

Zheng Xuan took a closer look, and the more he looked, the more surprised he became. He said happily: "Very good, very good! You got the answer right——

He Bian, you are smart and clever. I want to accept you as my disciple. Are you willing? "
