With a burst of laughter, Li Tai, a little fat man in a costume, walked in with a smile.
Kong Yingda and Xu Hongzhi, who were near the door, quickly got up and arched their hands: "I have seen His Royal Highness Wei Wang!"
Li Zexuan was also surprised, and said to Li Taiyao: "I have seen His Royal Highness Wei Wang!"
The other students looked at Li Tai in surprise. They were about to get up and salute, when they saw Li Tai smiled and waved his hands: "You don’t need to pay more. Today, the king came to the Imperial College to attend the class. From now on, I will be a student of the Academy. We will all be classmates in the future!"
"Buzz..."
The students under the class heard the words and talked.
"Oh my god, His Royal Highness Wang will be classmates with us in the future, did I hear it wrong?"
"It's incredible!"
"Our new gentleman is so powerful that he has attracted His Royal Highness King Wei!"
"I have decided. I will stay in the School of Comprehension in the future. With such a powerful gentleman, and a classmate of His Royal Highness King Wei, what should I do in the Four Schools Academy?"
"Brother Meng said so!"
………
As the saying goes, "learning to become a literary and martial artist, and the emperor's family", these scholars study hard, are they not in order to be appreciated by the emperor and leap into the dragon gate once? Now there is a king Wei, who is most beloved by His Majesty today, in the Mathematical Academy. Why do they still leave?
Kong Yingda heard that Li Tai was going to study in the School of Mathematical Sciences, was shocked, and quickly discouraged him from speaking, "Your Highness, this is absolutely not the case!"
Li Tai smiled and said: "Kong Jijiu, my father has already agreed to this matter, and I will be a student in the school in the future."
Kong Yingda shook his head helplessly and stepped aside.
Li Tai looked at Li Zexuan again and said, "Since the departure from the Qiqu Pavilion that day, Brother Li was knighted and appointed by my father to be a Doctor of Computational Supervision of the Imperial College. Brother Li is really prosperous! I don't know whether Dr. Li would like to Would you like to accept Xiao Wang as a student?"
Li Zexuan heard that Li Tai was coming to the school to be a student. Although he had no expression on his face, he was a little strange in his heart. I don’t know what the little fat guy is going to do again. Didn’t he abuse him enough last time? Want to come back and find a place?
Haha, come on, he is not afraid of this little fat man.
"Why did your Highness say this? It is said that there is no kind of teaching. Since the teaching is in the mathematics hall, naturally anyone can teach, but if your Highness enters the mathematics hall, there will only be teachers and students here, and there will be no King Wei. !"
This little fat man has to be vaccinated. If he comes over to show everyone the prince, how can he teach and how other students will learn?
Li Tai understood the meaning of Li Zexuan's words, and he smiled: "Of course, from now on, this is a school. My husband and my classmates can directly call me a green bird, and I won't put on the prince's appearance."
The last time he was in front of the Qiqu Pavilion, he was speechless by Li Zexuan's ten consecutive questions. Li Tai has regarded this as a lifelong shame. He was loved by the second grandson of Li since he was a child, and was praised many times for his brilliant intelligence. , How can I be willing to lose to Li Zexuan, an unknown boy who was previously unknown.
Yesterday, when he heard that Li Zexuan was going to be a postdoctoral fellow in mathematics, he was moved in his heart, thinking why not learn Li Zexuan's knowledge, and then use these knowledge to defeat him head-on, wouldn't it be better?
Therefore, Li Taicai asked Li Er to enter the arithmetic school to study. Li Er always dotes on this child, and this is not a big deal, so he naturally agreed.
Li Zexuan heard Li Tai's assurance and nodded and said, "The green bird, go find a place to sit down!"
Li Tai looked around, and finally sat between Tiedan and Lan'er with the disappointed expressions of some students.
Kong Yingda and Xu Hongzhi next to him widened their eyes in disbelief. Wei Wang was stubborn and known to the Manchu civil and military officials. Li Zexuan was not angry when he spoke to him in such a commanding tone. Could this be hallucinations?
After Li Tai sat down, Li Zexuan looked at him and asked, "Qing Que, you said you had a question before, so let's say it!"
Li Tai looked like a good baby, stood up and said, "Mr. Hui, the student’s problem is: today there are two people standing at the same time. A line rate is seven, B line rate is three, B travels east, and A travels ten steps northeast. B will ask A and B the geometry of each line"
Having said that, Li Tai's mouth evoked a nasty smile. This question was a very rare question that he asked several college graduates in the Weiwangfu Literature Museum to find. He specially wrote it down and wanted to find a chance to make trouble today. Yes, I didn't expect Li Zexuan to take the initiative to give him the opportunity to ask questions.
"Wow!"
In the teaching house, except for Li Zexuan and Li Tai, all the others were upset when they heard this question.
"This question is so difficult. Where did His Royal Highness Wei find such a difficult question?"
"I don't know, brother Ke, do you know?"
"It should come from the Pythagorean. I have seen it before, but it is too difficult to pick it up."
"Sigh~ It turned out to be the most difficult Pythagorean badge. Now Mr. Li is afraid that it will be more unfortunate."
"Yes, things are not good!"
Li Zexuan inherited the memory of his predecessor. Simple ancient prose is still understandable. The translation of this question is: It is known that A and B set off from the same place at the same time. A's speed is seven, B's speed is three, and B keeps going. Going east, A first walks ten steps south, then walks diagonally eastward for a while, and meets B. How far A and B have each gone
Hearing this question, he was really a little surprised, this little fat guy was really unkind today. If you want to solve this problem, you must use the Pythagorean theorem and the quadratic equation of one variable. If you change individuals, you will definitely be stumped. But how could he Li Zexuan be stumped by this junior high school math?
However, what Li Zexuan did not expect was that the ancients had already learned the Pythagorean theorem. His former mathematics teacher did not tell him. It seems that the wisdom of the ancients should not be underestimated at any time!
In fact, the Pythagorean theorem was recorded in detail here, but it was mainly applied in astronomy at that time.
At the beginning of the Pythagorean chapter, the Pythagorean theorem and its variants are first mentioned. The Pythagorean operation says: Pythagorean multiplied by each, and divided by the square, that is, the string is multiplied by the string, the string is multiplied by the subtracted string, and the rest is opened. Divide the square, that is, the tick. The tick is multiplied, and the string is subtracted.
Therefore, Pythagorean can be understood as a method of deriving the third side from both sides of a right triangle.
Li Zexuan quickly listed the equations in his mind and settled them. After a few breaths, he got the answer. This is the benefit of strong mental power, making his brain behave like a calculator.
"Hehe, Qingque is a very good question. Some of you may find this question difficult, but in fact, as long as you learn my new mathematics, this question can be solved with no more than a cup of tea."
After Li Zexuan finished speaking, the rest of the students were whispering in disbelief. Li Tai looked at him indifferently. In fact, what he thought was that Li Zexuan must be bragging~EbookFREE.me~Li Zexuan smiled and said, "This The answer to the question is that A has taken ten and a half steps, and B has taken twenty-four and a half steps, Qingque, am I right?"
Li Tai couldn't calm down anymore, he opened his mouth wide, and said: "How is this possible? It took two days for the bachelor of Wei Wangfu to calculate it!"
When the other students heard it, they knew that Li Zexuan had answered correctly, and they couldn't help cheering.
"Great, Mr. Li got the answer right, there is no need to leave the school!"
"Too great, Mr. Li is too great!"
"It's great that we can learn such a powerful math in the future, haha!"
Li Tai was stunned for a long time, but finally healed, and said to Li Zexuan: "Mr. Tai is convinced!"
When Lan'er saw this, her small eyes turned into crescent moons and she was very proud of having such a great brother.
Tie Dan also has a proud face.
Kong Yingda and Xu Hongzhi were both shocked and silent, and said in their hearts: It seems that this Guozijian has come to an extraordinary figure!
"Okay, two quarters of an hour is up, since you are not stumped to me, then I will be your husband from now on, starting from today, I will lead you to the door of mathematics, and then you will find that you have come to a new world!"
Li Zexuan looked at Shi Chen and said to the children.
Thank you Lao Gong for the surname Gong, the preface of the first name Gong, Tokyo is not too popular, and again for the reward!
Thank you for the two monthly tickets Lao Gong with the surname Gong and the preface.
