With a loud laugh, Li Tai, a fat little man dressed in fine clothes, walked in with a smile.
Kong Yingda and Xu Hongzhi, who were near the door, stood up quickly, cupped their hands and said, "I have met His Highness King Wei!"
Li Zexuan was also surprised, and he cupped his hands to Li Tai and said, "I have met His Highness the King of Wei!"
The other students looked at Li Tai in surprise. Just as they were about to stand up and salute, they saw Li Tai smiling and waving his hands: "No need to be polite. Today the King of Japan comes to the Imperial College to listen to the lectures. From now on, I will also be a student of the School of Arithmetic. We will all be classmates from now on!"
"Buzzing..."
The students in the hall were talking a lot after hearing this.
"Oh my god, His Highness the King of Wei will be our classmates from now on. Did I hear that right?"
"It's incredible!"
"Our new gentleman is so powerful that he even attracted His Highness King Wei!"
"I have decided that I will stay in the School of Arithmetic from now on. With such a powerful gentleman and classmates of His Highness the King of Wei, what else am I going to do in the Four Schools School?"
"Brother Meng is absolutely right!"
… …
As the saying goes, "If you learn literature and martial arts, your goods will be brought to the emperor's family." Isn't it because scholars like them study hard so that they can eventually be appreciated by the emperor and let the carp jump over the dragon's gate? Now that King Wei, whom His Majesty is most favored by now, has come to the Arithmetic Academy, why do they still want to leave
Kong Yingda was shocked when he heard that Li Tai was going to study at the Arithmetic School. He quickly spoke out to dissuade him: "Your Highness, this is absolutely impossible!"
Li Tai smiled and said: "Kong offers wine, my father has agreed to this, and I will be a student of the School of Arithmetic in the future."
Kong Yingda shook his head helplessly and stepped aside.
Li Tai looked at Li Zexuan again and said: "That day after we said goodbye to Qiquge Pavilion, Brother Li was first knighted and then appointed as a Doctor of Imperial Accountancy by my father. Brother Li really has a prosperous official career! I just don't know if Dr. Li is willing to do so. Are you willing to accept Xiao Wang as your student?"
Li Zexuan heard that Li Tai was coming to the School of Arithmeticology as a student. Although he had no expression on his face, he felt a little strange in his heart. He didn't know what the little fat guy was going to do again. Could it be that he hadn't been tortured enough by him last time? Want to get back some ground
Haha, come on, he's not afraid of this little fat guy.
"Why did Your Highness say this? As the saying goes, there is no distinction between teaching and learning. Since I teach in the School of Arithmetic, naturally anyone can teach. However, if His Highness enters the School of Arithmetic, there will only be teachers and students here, and there will be no King of Wei." !”
I have to give this little fat guy a vaccination. If he comes over to show off to everyone, how can I teach him, and how can other students learn from him
Li Tai understood the meaning of Li Zexuan's words, and he smiled and said: "Of course, from now on in this arithmetic school, sir and all my classmates can call me Qingque directly, and I will not act like a prince."
The last time he was in front of Qiquge Pavilion, he was left speechless by Li Zexuan's ten consecutive questions. Li Tai has regarded this matter as a lifelong shame. He has been loved by Li Er's eldest grandson since he was a child, and has been praised many times for his intelligence. , how could you be willing to lose to Li Zexuan, an unknown boy who was unknown before.
Yesterday, he heard that Li Zexuan was going to be a postdoctoral fellow in mathematics. He was moved and thought, wouldn't it be more satisfying to learn from Li Zexuan's knowledge and then use these knowledge to defeat him head-on
Therefore, Li Taicai asked Li Er to enter the arithmetic school to study. Li Er has always doted on this child, and since this was not a big deal, he naturally agreed.
When Li Zexuan heard Li Tai's assurance, he nodded and said, "Then Qingque, go find a seat and sit down!"
Li Tai looked around, and finally sat between Tiedan and Lan'er under the disappointed looks of some students.
Kong Yingda and Xu Hongzhi next to them opened their eyes in disbelief. King Wei was naughty, and everyone in the civil and military circles of the court knew it. Li Zexuan spoke to him in a commanding tone, but he was not angry at all. Could this be an hallucination
After Li Tai sat down, Li Zexuan looked at him and asked: "Qingque, you said before that you had a problem, tell me now!"
Li Tai looked like a good boy, stood up and cupped his hands and said: "Sir, the student's question is: there are two people standing together today. A walks with seven, B walks with three, B goes east, A goes south ten steps and diagonally northeast. Meeting with person B, ask person A and person B what their respective occupations are?"
Having said that, a malicious smile appeared on Li Tai's lips. This question was a very rare math question that he asked several bachelors in the Literature Museum of Prince Wei's Mansion to find. He wrote it down specifically, hoping to find an opportunity to attack it today. Yes, I didn’t expect Li Zexuan to take the initiative to give him a chance to ask questions.
"Wow!"
In the teaching building, except for Li Zexuan and Li Tai, everyone was in an uproar when they heard this question.
"This question is so difficult. Where did His Highness the King of Wei find such a difficult question?"
"I don't know, Brother Ke, do you know?"
"It should come from "Nine Chapters of Arithmetic" Pythagorean Chapter. I have seen it before, but it was too difficult and I didn't pick it up."
"Hiss~ It turned out to be the most difficult Pythagorean chapter. Now Mr. Li is probably in bad luck."
"Yeah, the situation is not good!"
... ... ... ... ... ..
Li Zexuan inherited the memory of his predecessor and could still understand the simple ancient Chinese. The translation of this question is: It is known that two people A and B start from the same place at the same time. A's speed is seven, B's speed is three, and B has been moving towards Walking east, A first walks ten steps south, and then walks diagonally to the north-east direction for a while before meeting B. How far did A and B go
Hearing this question, he was actually a little surprised. This little fat guy really came with bad intentions today. If you want to solve this problem, you must use the Pythagorean theorem and the quadratic equation. If it were another person, he would definitely be stumped. But how could he, Li Zexuan, be stumped by junior high school mathematics
However, what Li Zexuan didn't expect was that the ancients had already learned the Pythagorean Theorem. His former mathematics teacher did not tell him this. It seems that the wisdom of the ancients should not be underestimated at any time!
In fact, the Pythagorean Theorem is recorded in detail in "Nine Chapters of Arithmetic", but at that time it was mainly used in astronomy.
In the Pythagorean Chapter of "Nine Chapters of Arithmetic", the Pythagorean Theorem and its transformations are discussed at the beginning. Pythagorean Technique says: Pythagorean is multiplied by each, combined and divided by the square root, which is the string. And the strand multiplies itself, and the reduced string multiplies itself, and the rest are divided by the square root, which is the hook. Then hook and multiply by itself, reduce the string and multiply by itself, and divide the rest by taking the square root, which is the strand.
Therefore, Pythagorean technique can be understood as a method of deriving the third side of a right-angled triangle given two sides.
Li Zexuan quickly listed the equations in his mind and calculated the results. He came up with the answer in a few breaths. This is the benefit of strong mental power, which makes his brain work like a calculator.
"Haha, Qingque raised this question very well. Some of you may think this question is difficult, but in fact, as long as you learn my new arithmetic, you can solve this question in just a cup of tea."
After Li Zexuan finished speaking, the other students whispered in disbelief. Li Tai looked at him indifferently. In fact, what he was thinking was that Li Zexuan must be bragging.
Li Zexuan smiled and said: "The answer to this question is that A walked ten and a half steps, and B walked twenty-four and a half steps. Qingque, am I right?"
Li Tai couldn't remain calm now. He opened his mouth and said, "How is this possible? The bachelor of Prince Wei's palace calculated it for two days!"
When the other students heard this, they knew that Li Zexuan got the answer right again, and they couldn't help but cheer.
"Great, Mr. Li got the answer right, no need to leave the arithmetic center!"
"It's amazing, Mr. Li is so amazing!"
"It's great that we can learn such powerful arithmetic in the future, haha!"
... ... ... ...
Li Tai was stunned for a long time, and finally came to his senses. He cupped his hands to Li Zexuan and said, "Sir, he is very talented and knowledgeable. Tai is convinced!"
When Lan'er from behind saw this, her little eyes turned into crescent moons as she smiled, feeling very proud of having such a powerful brother.
Tiedan also looked proud.
Kong Yingda and Xu Hongzhi both rubbed their beards in shock and said nothing, thinking: It seems that a great big shot has come to the Imperial College!
"Okay, two-quarters of an hour is up. Since you haven't troubled me, I will be your husband from now on. From today on, I will lead you to the door of arithmetic. When the time comes, you will find that you have come to a new world. world!"
Li Zexuan looked at the clock and said loudly to the children.
