King of Liao at the end of Han Dynasty

Chapter 61 Arithmetic Sequences
After listening to Li Lin's words, Guan Ning said, "Have you ever read the "Sun Tzu's Mathematical Classics?"

Li Lin smiled and said, "I just heard about it a little bit. I have seen this topic in my father's secretary before."

Guan Ning said, "Then tell me, what is the answer?"

Li Lin thought about it briefly. The meaning of this question is that there are a batch of items, but I don't know how many there are.If you count three and three, you will be left with two; if you count five and five, you will be three; if you count seven and seven, you will be left with two.Q: How many items are there in total?

把它变成一个纯粹的数学问题就是：有一个数，用3除余2，用5除余3，用7除余2。求这个数。用3除余2，用7除也余2，所以用3与7的最小公倍数21除也余2，而用21除余2的数我们首先就会想到23；23恰好被5除余3，所以23就是本题的一个答案。

Li Lin said without hesitation, "This thing is twenty and three."

Guan Ning was stunned. He didn't know if he had made it simple, or if this kid was really so smart. Guan Ning thought about it for a long time and sighed, "You got the answer right."

Li Lin smiled briefly, but everyone on the side stared at Li Lin and Guan Ning intently as if they saw two girls dancing here. After a while, everyone realized and exclaimed, who I can think of a newcomer who dared to challenge the teacher and won, but Xu Miao counted with his fingers for a long time, then nodded and said, "That's right, Shimin was right!"

The crowd commotioned for a while, but Guan Ning stared at Li Lin intently, Li Lin was also not afraid, you stared at me, I was afraid to look at it?Lao Tzu is also staring at you.

Those who were dissatisfied said below, "Teacher, this doesn't count, maybe this kid knows the answer down below, and you are changing to someone he doesn't know!"

Li Lin knew that some people were dissatisfied, so he said again, "the teacher's question actually has many changes. If it is two of four or four, three of seven or seven, and two of nine or nine, then there are thirty and eight. If it is four Two of four, five of eight or eight, two of nine or nine, then things are still thirty and eight, if..."

Guan Ning raised his hand and said, "Okay, you answered this question correctly, come on, come up with a question!" After speaking, Guan Ning even made a gesture of invitation.

Li Lin smiled and said, "How dare this student?"

Guan Ning said unhappily, "You dare to challenge me, why not give me the first question!"

Li Lin thought for a while and thought, "Okay, since this is the case, I will ask. If the teacher hit me once with a ruler today, twice tomorrow, three times the day after tomorrow, and four times the day after tomorrow, and so on, ask Years later, teacher, how many times have you hit me with the ruler?"

After Li Lin asked, when someone was foaming at the table and passed out, some of the people who counted well hurriedly took over their abacus and began to count. Our long table is a larger table with an abacus on it, and Guan Ning also counted frantically.

Li Lin walked over in small steps and whispered to Guan Ning, "Teacher, I want to go to the toilet, can I..."

Guan Ning waved his hands again and again and said unhappily, "Go, go, go..."

Li Lin smiled jokingly, and walked out of the room with brisk steps.

Wandering around outside, I went to the latrine, and when I got to the kitchen, I was a little hungry in the morning. I asked if there was any food, and there were cakes for Guan Ning. Steal a few bucks.

Unexpectedly, he was so excited that he finished eating directly. Li Lin wiped his mouth and remembered that he didn't wash his hands after going to the toilet just now. Thinking about it, I was stumped by Guan Ning today, he might not be in the mood to eat pastries, so I thought I was helping others and ate for him.

Li Lin clapped his hands before walking towards the school. When he entered the door, everyone was still hard at work. Of course, there were already many who gave up. They watched others struggling to support them. When they saw Li Lin After coming in, he looked at Li Lin with the eyes of an alien, and Li Lin suddenly felt, isn't this arithmetic sequence a little difficult for them?

Li Lin walked up to Guan Ning and whispered, "Teacher, have you ever made it?"

Guan Ning looked at Li Lin with very complicated eyes, and said somewhat discouragedly, "No!"

Li Lin smiled and said, "Or I'll tell you the answer directly!"

Guan Ning said unhappily, "No, I won't eat or sleep if I can't solve this problem today!" Then he looked at the students who couldn't figure it out, and Guan Ning shouted, "You too!"

"Ah..." There was a scream from below.

Li Lin shook his head and smiled wryly, "Teacher, there's no need to do this. If you really can't figure it out, you can ask. Zi once said, if a gentleman is not ashamed to ask, students will definitely tell the teacher the mystery."

This is the last student, who just said that Li Lin would have the same atmosphere. He threw his abacus and shouted, "Forget it! What kind of question is this!"

Then he looked at Li Lin with a bad face, pointed at Li Lin and said, "You must have imagined this question randomly. You are just talking nonsense, and you can't figure it out at all!"

Li Lin went over with a smirk and asked, "Why do you think I can't figure it out?"

This question was stopped by this person, and the person stammered, "Even the teacher can't figure it out, how could you figure it out."

Li Lin said, "Hehe, what will you do if I figure it out!"

The man thought for a while, then looked around at the classmates and Guan Ning who were still struggling to calculate, and thought how could a sloppy person like Li Lin figure out such a perverted problem, so he said bluntly, "If you figure it out, Do whatever you say!"

Li Lin laughed and said, "Okay! That's what you said, and the gentleman said it quickly!" Li Lin stretched out his hand.

The man immediately got up and patted Li Lin's hand, "The same is for sure, I, Gongsun Kang, will never break my promise!"

Li Lin's face changed when he heard this, "Gongsun Kang!Damn, isn't it the son of Lao Tzu who killed his father's enemy?Damn, there is a way to heaven if you don't go, but there is no way to hell you break in!Really courting death! '

Li Lin's complexion changed very quickly, and he smiled, "Okay! If I win, I want your family's property, do you dare to give it to me?"

How could Gongsun Kang react to what Li Lin said, but he didn't know what to say, so he hesitated to answer, Li Lin laughed and said, "Haha, I'm just joking with you, huh! Even if I care about you I don't dare to give it to you, I want you to wash my clothes for half a year!"

Gongsun Kang saw that this one was much better than the one just now. Isn’t it just for washing clothes? Gongsun Kang nodded and said, “Okay! It’s settled!”

Li Lin picked up the writing brush on Gongsun Kang's desk with a smile, wrote a series of numbers on his desk, and then said to Gongsun Kang, "This is the answer. If anyone calculates it, he will know it by himself. Whether it is right or not is free to decide!" "

When everyone saw that Li Lin had written the answer, they rushed over to look at it. Even Guan Ning's eyes were attracted to him. Of course, he was very calm and did not rush over directly.

"Shimin really wrote it?"

"Oh my god, what a god-man, he actually knows such a topic?"

........................

A group of students discussed for a while, while Li Lin walked back to Fang Meimei's sleep in the T-size.

Guan Ning is a great contemporary Confucianist, and of course he is the first in calculation. Faced with this kind of problem that has surpassed the millennium, he has been counting without sleep until late at night. It is almost dawn, and he finally figured out the answer. Come to Dao Gongsun Kang's table Looking at Li Lin's writing on the Internet, Guan Ning was stunned, "Sixty-six thousand seven hundred and ninety five, this... This kid is a genius! Just who the hell did you send me!"

Guan Ning saw Li Lin's catastrophe, and sighed. Of course, Gongsun Kang was very concerned about this matter, so he immediately came over and asked Guan Ning, "Teacher, is the answer written by Li Shimin correct?"

Guan Ning glanced at this disappointing apprentice, compared with Li Lin, and immediately recommended Li Lin to the top, and said in a bad mood, "From now on, you have to do laundry for others!"

Gongsun Kang was stunned on the spot, and said to himself, "Impossible, impossible, how could this kid do it, how could he do it, such a difficult question, even the teacher has been counting for so long, how could he... ah !" Gongsun Kang suddenly felt that Li Lin was his enemy, not only did he want to wash the clothes for the first half of the year, but he didn't know that Li Lin had already regarded him as his enemy and put him on his blacklist.

Guan Ning returned to his room in a trance, stayed there for a while, and immediately took out the bamboo slips to write a letter, of course to Bing Yuan. He became more and more curious about this Li Shimin. I introduced someone to myself, and I also said in my heart that this kid is good, but the writing is still very vague, so I must ask carefully......

And in the T-shaped room, there are quite a lot of people in it now. After seeing what Li Lin did today, everyone is full of curiosity about Li Lin, and even has some admiration. Who would have thought that a student just now would win the teacher to But Li Lin is sleeping soundly now, time conscious late at night, these people insist on taking a look at the sleeping Li Lin.

But Li Lin was awakened by a sound. Li Lin slowly opened his eyes, and saw that there were several big faces looking at him in front of him, and immediately regained his energy. "Oh my god! What are you doing?" Eyes puzzled.

Yan Rou said honestly, "Hey, Shimin, we are just curious about you, tell me how you calculated those two questions today?"

Li Lin said, "Why, the teacher has already figured it out?"

Everyone nodded and said, "Well, I also said a few strange words, and then asked Gongsun Kang to wash your clothes for you in the future. Although I didn't say that you did the right thing, it must be you who asked Gongsun Kang to wash your clothes for you." That's right!"

Li Lin nodded and said, "Oh, then what are you doing here, go to bed quickly! It's all playing like this!"
