In the blink of an eye, it was ten days after what Luo Yan said. Pen ~ fun ~ pavilion www.biquge.info

Since three or four days ago, a large number of arithmetic enthusiasts began to gather in the city of Golden State. Different from the poetry clubs and literary clubs in the literary world, arithmetic is originally a boring thing, where can I find any fun in daily life. In many cases, the gathering of the academic community is three or five friends to discuss their views on a certain issue. As for more, everyone wants more good things to come out, but they can't find it.

I remember that the last most lively arithmetic assembly should have been Wang Xiaotong's "Ancient Arithmetic". At that time, many masters and famous masters took their disciples to Chang'an to congratulate. It was precisely because of that rally that the young generation had the opportunity to get to know each other.

Zhang Tong was also up-and-coming back then, and many young people who were about the same age as him also admired his ability. I suddenly heard that he was going to worship under a person with such a bad reputation as Luo Yan, and through that day's competition, many people also had a new understanding of Luo Yan. If you want to make more progress, or just out of curiosity, for whatever reason, there are a lot of people from the younger generation who have real talents.

Early this morning, many high-spirited young people came out of the major inns in Jinzhou one after another. Regardless of how they are dressed, that spirit alone is worthy of a thumbs up. With different or the same purpose, these people all set out for their destination, the Golden State State.

I don't know if I don't see it, and I'm shocked when I see it. So many people came to the state to study, and they found that there were many old acquaintances.

"Brother Zhou, I didn't expect you to come too. Why, are you interested in four places? ”

"It's false to say that I'm not interested, but looking at that solution these days, there's a lot of fun in it. I think that if I can study with this Dr. Luo for a few months, I will definitely gain a lot. ”

"Hey, Brother Yang, I haven't seen you for a few years, but I didn't expect to meet here today."

"That's right. Unexpectedly, Brother Song actually came over from Jiangnan, and when he said goodbye that day, he still remembered Brother Song's high-spirited appearance. It's great to see you today, as usual. ”

"Look, who's that? I didn't expect this one to come. ”

In the midst of the commotion, a young man dressed in light blue clothes walked into the crowd. Although he is not very old, as long as he knows him, there is a trace of admiration in his eyes. Of course, those who don't know can only quietly ask others what the identity of this young man is.

"He? You don't know him, it seems that you didn't have the qualifications to go to Chang'an a few years ago. This is the legendary Zu Jixian, the best descendant of the ancestral family. ”

"It turned out to be him, it seems that today is lively. No matter what his purpose is, but with the participation of these people, this recruitment will definitely not be dull. ”

Many people nodded in agreement: "Not only him, but I have also seen many descendants of families and masters." Alas, if I had known that there was today, I should have applied early than to compete with these people. There's no chance at all. ”

Those arithmetic scholars in Golden State and several nearby states and counties lamented in unison, if there had not been so much hesitation at the beginning, there would not be today's dispute.

When there were different opinions, the door of the state school "squeaked". Like an order in the army, everyone suddenly fell silent, and their eyes shot together at the slowly opening gate. When there was a person who could enter or leave, suddenly a head poked out. "Well, I don't want you to come so early. Let everyone wait for a long time, Zhang is here to make amends to you. ”

After saying a word, the head slowly stretched out, gradually revealing the body, and finally even the legs and feet stepped out of the threshold, followed by a bow.

Surprisingly, it's Zhang Tong.

"Brother Zhang, I haven't seen you for a few years, how did you start this porter's work." Slightly teasingly, Zu Jixian returned the salute to Zhang Tong.

But the two of them are from the same arithmetic family, and there is not much difference in age, after Chang'an saw each other, the two often exchanged letters. It is precisely because of such a deep friendship that Zu Jixian dared to laugh at Zhang Tong like this. As for the few around Zu Jixian, although they don't have such a deep friendship with Zhang Tong, they can be regarded as knowing each other. After returning the salute to Zhang Tong, he followed behind Zu Jixian and greeted Zhang Tong, and inquired about Luo Yan's news by the way.

"It turned out to be the elder brother of the ancestral family. Haha, I don't want to come either, but Master Luo told me that if there is something to do, the disciple will obey him, and I can't refute it, so I can only listen to him obediently. Between the words, the respect for Luo Yan surprised everyone present. Zhang Tong hasn't officially apprenticed yet, but the attitude in front of him is obviously to treat Luo Yan as a teacher. Without the slightest pretentiousness and amusement, this "Luo Shi" called out, and many people heard Zhang Tong's admiration.

"Brother Zhang, what kind of soup did Dr. Luo pour you to make you so happy?" Puzzled, Zu Jixian asked.

With a faint smile, Zhang Tong said: "Only by studying with Master Luo for a period of time can I know that what I have learned is just scratching the surface." Since following Master Luo, I have learned that there are so many things in this world that I don't know. Looking back, it was true that I was arrogant. ”

Hearing that Zhang Tong has been blowing the conch for Luo Yan, Zu Jixian is also a little impatient. At the beginning, the two were talents who were neck and neck, but now the person in front of them is worshipping under a peer and boasting like this. Isn't this a downgrading of one's status as a person? After Zhang Tong finished saying this, Zu Jixian said: "Okay, okay, I already know your ability as Master Luo." I'm waiting to come today, presumably Brother Zhang also knows what the purpose is. I don't want to learn from this Dr. Luo, I just want to meet the grandmaster who suddenly appeared among his peers. ”

Seeing Zu Jixian's impulsiveness, Zhang Tong seemed to think of himself that day. Without saying much, he took out three pieces of paper from his bosom and said, "Master Luo also knows what you mean. So before I came, I was given the topic of getting started. Ladies and gentlemen, if you want to see Master Luo, answer all three questions. ”

After finishing speaking, he unfolded the paper and read out the first question: "The water of Pingping Lake is clear and clear, and the red lotus is half a foot on the surface." The mud is not stained, and it is suddenly blown by a strong wind. The fisherman watched and moved forward, and the flower was two feet away from its original position. Can count the gentlemen, please solve the problem, how to know the depth of the lake. ”

This is an obvious application of the Pythagorean theorem, and the key is to be able to clearly understand the meaning of the problem. Many scholars have also read books, and they will not understand where they will understand. In addition to mental arithmetic, I can't help but complain about the form of Luo Yan's question: This Dr. Luo wants to write poems and wants to go crazy, and he doesn't even let go of this topic. Alas, in the future, if you count this number, do you have to learn to write poetry first?

Soon everyone reported the answer. Zhang Tong waited for the voice in the crowd to fall, and then said: "Three-quarters of a foot friend, please come forward, and the rest of you, please stand back." Three-quarters of a foot is the answer. This is an introductory qualification question, and the first one is just to get rid of some onlookers, so the difficulty is relatively low.

There was a rush of chaos, and there were already hundreds of soldiers standing in front of the crowd. Obviously, these are the people who got it right.

"The second question, Luo Yan walked on the street and carried a pot to buy wine. Double the store, and drink a bucket of flowers. Three encounters with shops and flowers, after drinking the wine in the pot. How much wine was there in the pot? As soon as this question came out, many people couldn't help but laugh "poof". It's too playful, isn't it? If you come up with a question, you have to write a poem, and you just have to write a poem, and you have to write yourself in. Is this for fear that you don't know that the topic is you?

This problem requires far more brain power than the simple Pythagorean theorem can solve. It's a simple univariate equation, but that's where the difficulty comes and goes. thought that after a cup of tea, someone reported the answer. At first glance, it is the ancestor Jixian. Only then did someone answer one after another, but it had been dragging on for a long time.

"Seven-eighths of a bucket. The first 50 friends who answered correctly should also take two steps forward. ”

"Question 3. Today, there are strands that are more powerful and more multiplied by strands. Only the cloud hook power plus chord is more and the same as the hook multiplication chord. Q: Strand geometry? ”

This is a binary cubic equation. The conditions given by the problem and the Pythagorean theorem also require a lot of calculations to solve. For a while, the people who were still a little proud suddenly withered.

Cubic equations are a mathematical achievement that has only been developed in recent years. Generally speaking, there are very few topics that can be encountered, but I didn't expect to come out in this Golden State today. What's maddening is that this question is an introductory question to test yourself.

Seeing that the faces of these people in front of him changed instantly, and they began to frown, Zhang Tong was amused in his heart. If I had been ten days ago, I am afraid I would have been like this. But just yesterday, Luo Yan used this problem as an example to explain the cubic equation, which made him pause. Now when I encounter a similar question, I am afraid that if I think carefully in my head, I can get the correct answer.

looked at it with a smile, and after waiting for a stick of incense, a few people said their calculated answers weakly. Of course, in order to prevent someone from fishing in troubled waters, this round requires a solution method. In this way, half of the incense burnt time passed, the withdrawal of those who quit, the wrong answers, and in the end, there were only eleven people left.

Zhang Tong nodded. Originally, what Luo Yan explained to him was that the twenty people who answered the correct answer first in the last round entered the state school to receive the final test. Unexpectedly, in the end, there were not even twenty people.

After a glance, Zhang Tong found that several of them were the children of celebrities from various families. didn't say much, just nodded and said, "Everyone, since you have passed the test of these three questions. Then please move to the door, Luo Shi is still waiting to meet and talk to you. ”

After listening to Zhang Tong's words, the eleven people didn't say much, nodded, and followed Zhang Tong into the door.

Outside the door, the scholars gradually dispersed in sighs. In the crowd, an elderly man also walked away with the crowd at this moment, but with a smile on his lips. (To be continued.) )
