"Fang Xianzi is reasonable, Li Yang, you come to consult with His Highness."

Fang Yiai sent his own disciples, Wang Xiaotong naturally refused to drop the price, and went out to compare with Li Taibi, and also sent his own proud disciples.

"Yes!"

As soon as Wang Xiaotong's words fell, a prisoner walked out of the crowd, this person was not tall, the whole person looked very capable, and his eyes were shrewd and confident.

"The students have seen His Royal Highness King Yue! I don't know how Your Highness compares? ”

"Otherwise, the two of you will each come up with three questions, which is more than who can answer the questions correctly." Someone on the side suggested.

Li Tai was also very confident, "No need, this king has studied arithmetic with Mr. Zu Xiaosun, you wait until you understand my plenum, this king will come up with a question first, who can answer, let's continue." ”

"Okay." Li Yang replied confidently.

But he didn't notice the playful smile on the corner of Li Tai's mouth.

This time, the little fat man can be said to be well prepared, and he abused them in terms of equipment alone, and brought pencils, compasses, and triangles with him.

"Have you ever learned the Pythagorean algorithm?"

Seeing Li Yang nodding, the little fat man continued to ask: "Then let me ask you, the Pythagorean are all one, and the strings are geometrical?" ”

As soon as Li Tai's voice fell, the doctors and supervisors all lowered their heads and pondered, and after a cup of tea, Li Yang on the other side was already sweating profusely.

Fang Yiai watched from the side, the corners of his mouth twitched, he didn't expect this kid to be so ruthless.

This is another irrational number, how do they calculate!

Although China was the first in the world to introduce the decimal point, which did not cause a mathematical crisis, and also discovered pi, there was no concept of irrational numbers in ancient times.

"The number that Your Highness said is not the number of Pythagorean numbers." In the end, Wang Xiaotong came forward and denied his problem.

"I can draw it, why not the Pythagorean number!" Li Tai said, "Boom" and drew a right triangle on the paper.

Everyone can see it clearly, and there is no way to refute it.

Li Yang was angry, and asked angrily: "Then His Highness said that it was for geometry?" ”

"The answer is: root number two."

Li Tai wrote it down as he spoke, and without waiting for others to question it, he went on to explain: "A new number discovered by my master is the same number as the ancestral rate, which is called 'irrational number'. ”

Hearing this, the people at the scene stayed there, and they could be as famous as the ancestors! Isn't it going to go down in history......

looked at Fang Yiai's eyes, revealing a strange look.

"Your Highness is like this, it's obviously opportunistic!"

The prisoners of Guozi were naturally not convinced, and together they accused Li Taisheng of being unmartial, and the little fat man smiled disdainfully and said, "Okay! Listen to the next question......"

After that, he asked three questions in a row, and none of the subjects, including Wang Xiaotong, could answer them.

One by one, they bowed their heads, so that their faces were flushed, Wang Xiaotong could afford to put it down, and bowed to Fang Yiai, "Fang Xianzi's talent is admired by the officials, and I am not as good as far away in arithmetic." ”

Wang Xiaotong took the lead, and the supervisors of the discipline generously admitted defeat, and saluted Fang Yiai and Li Tai.

The status of the discipline is already low, and they admit defeat, and the people in other departments of Guozijian are unwilling to admit that Guozijian will lose because of their failure.

"It's not enough to learn from Little Doyle, and it's nothing if you win."

"If you have the ability, we will compare the subset of scriptures and history, what is the use of these."

The other inmates made all kinds of provocations, and the superintendents lowered their heads in shame, not daring to refute, and shrank back one by one.

"Do you really want to compare?"

Fang Yiai smiled lightly and said: "The gentlemen of our primary school subset of classics and history are Mr. Li Gang, Mr. Yan Silu, and Mr. Chu Liang. ”

Seeing the provocation of the prisoners, the little fat man was eager to try, he was extremely smart since he was a child, and he naturally did not lose to them in terms of the subset of history.

But Fang Yiai is here to invite someone, so naturally he won't bother too much.

As soon as he said this, the scene was silent.

The young man was strong-blooded, and in a hurry, he forgot about this matter, and he had caused a sensation in Chang'an for a period of time before.

Wherever Fang Yiai's eyes passed, he shrank his head one by one, not daring to look at him.

"Which of you is coming?"

He deliberately asked again, and the prisoners began to blame each other, and they were unwilling to stand up. Fang Yi was proud in love, and thought: "Does this count as me, I picked the country by myself......"

The other side.

Kong Yingda, the priest of the country, also heard about this discussion, paid attention to the movement here, and when he learned about the actions of the prisoners, he killed him angrily.

Zi said: See the sages and think together! You don't want to forge ahead, and you have read the books of sages for so many years! ”

"Arithmetic is one of the six arts, who said that arithmetic is a trail!"

Kong Yida scolded him all the time, and the prisoners all had solemn expressions, bowed their heads and did not dare to speak, and respectfully bowed, saying, "The students know that they are wrong. ”

"Those who make trouble will receive thirty precepts per person!"

"No!"

None of the prisoners escaped their guilt and bowed their heads to punishment. He bowed his hand to Wang Xiaotong again and said, "Dr. Wang, the student is vain, don't go to your heart. ”

"The sacrificial wine is serious."

Wang Xiaotong squeezed out a smile, he still has a lot of respect for Kong Yingda.

"Fang Xianzi ......"

After dealing with the housekeeping, he turned to look at Fang Yiai. Fang Yiai immediately said modestly: "You are always tormenting the boy, just call it the last love." ”

"The purpose of your coming, the old man is also clear, and the school is running well. But the inmates are mainly studying, and you can recruit those who have completed their studies. ”

Fang Yiai thanked him respectfully, "The kid is clear, thank you, sir." ”

"I heard that the three gentlemen are in the academy?"

"Yes, gentlemen say 'there is no class,' and they are willing to condescend to the elementary school."

"I'm not as far away as Mr. Wenji."

The two chatted a few more words, Fang Yiai said goodbye and left, not daring to drive Kong Yingda to see him off, Wang Xiaotong sent him away, he also had other thoughts.

"How about a doctor coming to teach in our primary school? You and I can study and discuss mathematics together ......"

Wang Xiaotong was stunned when he heard this, and hesitated in his heart, although Guozijian was not taken seriously, it was the highest university in the Tang Dynasty after all.

Fang Yiai continued to add: "Doctors can seriously consider that mathematics is a compulsory subject in our primary school, and there will always be a few good seedlings who can carry forward arithmetic." ”

"The restraint is also several times that of the national prison, so that the family can live without worry."

Before Wang Xiaotong could answer, he heard an angry roar from behind, "Okay, you have a bereavement of love, please let the three gentlemen Li Gang not be satisfied, and the diggers actually dug up the Guozijian!" ”

In the past, Li Shimin really didn't pay much attention to arithmetic, but after communicating with Li Tai from Lishan Xinggong, he paid more and more attention to arithmetic.

I heard the news today and rushed over.

Fang Yiai suddenly felt the strong wind behind him, and he didn't have to think about it, it must be Li Shimin's flying foot.

He theorized while escaping: "Your Majesty misunderstood, the students taught by Chen Primary School are not still working for Datang, how can there be such a thing as poaching people." ”
