"Okay, I also want to see how good the Chingnu is at the lecture?"

Li Er naturally would not refuse such a request. He had long heard that the educational methods of Mount Li College were unique and completely different from those of Imperial College and some private schools, which had long aroused his curiosity. Since he had such an opportunity, he naturally would not miss it.

"Tsk tsk! Your Highness is actually late, do you think your Highness forgets that he has a class himself today?"

Qin Huaiyu said with a smile. He had never seen His Highness make a mistake. Now he has made a mistake in his academy. He really couldn't imagine how His Highness would solve this problem.

"Why do I go and remind Your Highness, after all, Your Highness has been extremely hard for a while."

Cheng Chumo looked embarrassed. He could feel the hard work of Xiao Zhengtai for the sake of their efforts. His Highness is also a human being, not a god. Even if he is a god, God still has time to rest.

"No need, this prince is not so confused yet. Today, two new classmates are here, everyone applauds and welcomes you!"

As soon as Cheng Chumo finished speaking, Xiao Zhengtai walked in with big strides and began to inspire everyone, which made everyone very confused.

Just as everyone stood up to say goodbye to His Royal Highness the Crown Prince, Li Er and Changsun Wugui also walked in with a smile on their faces.

"The last general Cheng Chumo, please see Your Majesty, and see the Queen!"

"The last general Qin Huaiyu, meet your Majesty, and meet the Empress!"

"Caomin Changsun Chong, please see Your Majesty and meet the Empress!"

...

As several people took the lead in showing their salutes, the other students also reported it and quickly greeted the two of them respectfully.

"No need to be polite. Today I am your classmates. I will accompany you to study together. I hope you can be more serious than usual."

Li Er had a warm smile on his face. This was the first time he felt such a scene. These were all hopes for the future of the Tang Dynasty. Li Er was very eager for Xiao Zhengtai to bring him a surprise.

His Majesty actually said that he would become classmates with them and listen to the teacher's lectures together.

What an honor this is? I am afraid that I have never had such treatment for so many years since the Imperial College was established.

As for those poor children, they were even more excited. They didn't expect that they would have a glimpse of the dragon's face in their lifetime.

When everyone was excited, Li Er and the queen walked to the end and sat quietly, waiting for the teacher's explanation like ordinary students.

"It seems that your Majesty's arrival has made you very excited! Since this is the case, then next, I hope that you can actively answer questions and show your strength in front of your superiors."

Xiao Zhengta looked at the students below and couldn't help but smile.

"yes!"

All the students immediately answered loudly and showed Li Er an unprecedented cohesion.

"Very good, let's get back to the topic below and read the question!"

After finishing his words, Xiao Zhengta turned around and wrote quickly on the blackboard.

The content is: "The duck and the rabbit are locked in a cage together, with thirty-five heads on top and ninety-four heads on bottom. Ask, how many ducks and rabbits are there in the cage?"

"Mom..."

Looking at such a question, Cheng Chumo was dumbfounded. The calculation he hated the most was that he would have no chance to show it in front of His Majesty.

"Duck, two feet, rabbit, four feet..."

Yin Yuan frowned and murmured softly. Obviously, such a question brought them great trouble.

"What does the queen think?"

Li Er stared at the blackboard with his eyes lit up, his cheeks full of excitement. Such a question is indeed novel and attractive enough.

"Here I'm not good at this."

Changsun Wugui gently felt her forehead. Just thinking about the feet of a group of ducks and rabbits, she felt dizzy in front of her. As for answering this question, don't even think about it.

"It's almost time, can someone answer the correct answer?"

After waiting for a quarter of an hour, Xiao Zhengtai started to ask everyone.

"Your Highness, Cheng Chuliang calculated that there are twelve rabbits and twenty-three ducks."

Just as everyone was looking at each other, Li Yan'er raised her arm to announce the answer.

What?

Cheng Chuliang?

True or fake?

Is this impossible?

Everyone's eyes fell on Cheng Chuliang in an instant.

"Yes, the answer is correct. Chu Liang, let me explain to you how you calculated it."

Xiao Zhengtai was also very surprised. Among these students, Cheng Chuliang's grades were not very good, especially what he was going to talk about today was a new calculation method. I really didn't expect this kid to do it right.

"Your Highness...I...I...This..."

After being urged by the prince, Cheng Chuliang was about to cry in a hurry. He didn't calculate it at all, so he asked him to stand out and explain.

Xiao Zhengtai was very confused and came to Cheng Chuliang's side. After picking up his notebook, he immediately turned black in front of him. What a guy, this guy is also a talented man.

He drew several pages of ducks and rabbits on the notebook, probably counted with one leg and one leg. Of course, this was also his luck, and he could find the answer in such a short time.

"Damn! Is there such an operation?"

As a top student, Changsun Chong was stunned when he saw Cheng Chuliang's solution. What kind of thinking is required to imagine such a solution.

No matter what, they have done it right and surpassed everyone, so they can't accept it.

"Chuliang, beautifully done!"

Everyone gave Cheng Chuliang a thumbs up, without any intention of mocking him, and of course, they did not admire him. At least the topic that Your Highness created was an explanation in front of His Majesty.

"Chu Liang, it is worthy of praise to be able to think of this, but your solution to the problem is too complicated. This is also the new knowledge that the prince taught you today.

Assuming that all of these thirty-five heads are duck heads, what will happen?"

After finishing his words, Xiao Zhengtai wrote a 35-digit number on the blackboard and looked at the students below calmly.

"No! Your Highness, if all thirty-five heads are ducks, then there should be seventy legs. There are still twenty-four legs in the question."

Changsun Chong frowned and calculated carefully, and the doubts in his heart became even greater.

"That's right. All the extra feet are rabbits. Now, the twenty-four feet are divided into two legs on the original basis. How many times can they be divided into them? That means how many rabbits are there in total."

Xiao Zhengtai nodded to Changsun Chong with satisfaction and continued to explain.

As soon as he finished speaking, many students calculated it in the notebook and concluded that they were really twelve.

"How is it? Are there any other things I don't know?"

Such questions often appear in later generations and are very easy to mislead students. If you have a little carelessness, you will make mistakes.
