With a burst of laughter, Li Tai, the little fat man, walked in with a big 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 rest of the 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, "It doesn't need to be too much. The king came to the Imperial College today to attend the class. From now on, I will also be a student of the Academy. Students, we will all be classmates in the future!"

"Buzzing..."

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 you wrong?"

"It's incredible!"

"Our new gentleman is so powerful, he has attracted His Royal Highness Wei Wang!"

"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?"

"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, not in order to be appreciated by the emperor in the end, and once the carp jumps over the dragon gate? Now there is a king Wei, who is the most beloved by His Majesty today, in the School of Mathematical Studies. Why are they leaving?

Kong Yingda heard that Li Tai was going to study in the School of Mathematical Studies, so he was shocked and quickly discouraged him: "His Royal Highness, this must not be done!"

Li Tai smiled and said: "Kong Jijiu, my father has agreed to this matter, and I will be a student in the school in the future."

Kong Yingda reluctantly shook his head and stepped aside.

Li Tai looked at Li Zexuan again and said: "That day, after leaving the Qiqu Pavilion, Brother Li was knighted and appointed by my father to be a doctor of mathematics in the Imperial College. Brother Li is really a prosperous official! Is the doctor willing 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 this little fat guy is going to do again. Didn’t he get caught by himself last time? Enough abuse, want to come over and find a place?

Haha, come on, come on, he is not afraid of this little fat man.

"Why did your Highness say this? As the saying goes, there is no kind of teaching. Since the teaching is in the mathematics hall, naturally anyone can teach, but if his majesty enters the mathematics hall, there will only be teachers and students here, and nothing more. King Wei!"

I have to give this little fat man a vaccination. If he comes over to show everyone the prince, how can he teach himself and how other students learn?

Li Tai understood the meaning of Li Zexuan's words, and he smiled: "Of course, from now on, this is an academy. My husband and other classmates can directly call me the green bird, and I won't put on the prince. "

The last time he was in front of 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 eldest grandson of Li since he was a child. Praising for his ingenuity, how could he 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?

So 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: "Then Qingque, 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 opened their eyes in disbelief. Wei Wang was stubborn, well known by the civil and military officials of the Manchu Dynasty. When Li Zexuan spoke to him in such a commanding tone, he was not angry. An illusion?

After Li Tai sat down, Li Zexuan looked at him and asked: "Qing Que, you said you had a question before, now let’s say it!"

Li Tai looked like a good baby, stood up and said, "Mr. Hui, the student’s question is: today there are two people standing at the same time. Obliquely northeast and meeting B, ask A and B each line geometry"

After all, Li Tai's mouth evoked a nasty smile. This question was a very rare question that he asked several scholars in the Wei Wangfu Literature Museum to find. He specially wrote it down and thought about it today. Looking for an opportunity to start a trouble, Li Zexuan unexpectedly offered him a chance to ask questions.

"Wow!"

In the teaching house, except for Li Zexuan and Li Tai, everyone else was in an uproar upon hearing this question.

"This question is so difficult, where did His Highness King Wei collect such a difficult question?"

"I don't know, brother Ke, do you know?"

"It should come from the Pythagorean chapter. I have seen it before, but it is too difficult to get it out."

"Hiss~ It turned out to be the most difficult Pythagorean badge. Now Mr. Li is afraid that it will be too bad for you."

"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, and B’s speed is three. B keeps going east, A first walks ten steps south, then walks diagonally to the east for a while, and then meets B. How far A and B have each gone

When he heard 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 one-dimensional quadratic equation. 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, I first talked about the Pythagorean theorem and its deformation. The Pythagorean technique says: Pythagorean multiplied by each, and the square is divided, that is, the string is multiplied by the string, and the string is multiplied by the reduced string. , Divide the remaining squares, that is, hook. And multiply by hooks, multiply by subtracting strings, and divide the remaining squares, namely stocks.

Therefore, Pythagorean technique can be understood as a method in which two sides of a right triangle are known to find the third side.

Li Zexuan quickly lays out the equation in his mind and settles it. The answer is obtained within a few breaths. 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 math, 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~IndoMTL.com~Li Zexuan smiled and said:" The answer to this 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 the Wei Palace to calculate it!"

When the other students heard this, they knew that Li Zexuan had answered correctly again, and they couldn't help cheering.

"It's great, Mr. Li got the right answer. You don't have to leave the school!"

"That's amazing, Mr. Li is so amazing!"

"It's great that we can learn such a great arithmetic in the future, haha!"

Li Tai was stunned for a long time, and finally healed, and said to Li Zexuan: "Mr. Tae has learned extensively, and Tai is convinced!"

Lan'er at the back saw it, her small eyes turned into crescent moons, and she was very proud of having such a great brother.

The iron egg is also very proud.

Kong Yingda and Xu Hongzhi were both shocked and silent, and said in their hearts: It seems that this Guozijian is a great figure!

"Okay, two quarters of an hour are up, since you didn’t stump me, then I will be your husband from now on. Starting today, I will lead you to the gate of mathematics, and you will find that you come Into 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 is Gong, Tokyo is not too popular, and again for another reward!
