Tang Dynasty: The beginning of the game is to touch the Princess Changle

"Your Majesty, I suggest that starting from now, the enlightenment books of the Imperial College must be annotated with this punctuation mark, and the previous academic classics must be revised."

After listening to Su Chen's explanation of punctuation marks, Kong Yingda immediately suggested to Li Shimin.

"Please grant your approval, Your Majesty!"

The other four also followed suit, and Fang Xuanling and Wei Zheng also bowed.

Li Shimin glanced at the knowledgeable ministers and nodded:

"Master Kong, please don't be polite, I will fully support this matter!"

After thinking, Li Shimin said, "Dai Aiqing, I will allocate 800,000 strings of cash from the national treasury to revise the ancient sage classics. I will trouble you gentlemen for this matter."

"Minister, obey your order!" Dai Zhou and Kong Yingda bowed at the same time.

After the matter was settled, Kong Yingda walked towards Su Chen and bowed, saying, "Mr. Su, I have another question to ask you. Please don't hesitate to enlighten me!"

"Mr. Kong, there is no need to be so polite. You can just call me Su Chen." Su Chen bowed and smiled.

He had already guessed who this person was. Li Shimin always called him Master Kong.

"Master Kong, gentlemen, there is no need to be so polite to that boy. Just call him Su Chen. Just don't blame him for not knowing etiquette."

Li Shimin also smiled at the five people beside him.

"Yes, yes, yes, your majesty is right. The boy does not know etiquette. Just don't be offended!" Su Chen quickly followed and echoed.

Kong Yingda and the other five looked at Su Chen and nodded with a smile.

"Hahaha, such an open-minded and knowledgeable young man, how dare I and others blame him!" Kong Yingda also stopped his previous stubbornness and smiled.

Su Chen scratched his head, "I wonder what Mr. Kong wants to ask me?"

Kong Yingda straightened his face. They can be serious about learning.

"Su Chen, I want to ask whether there are deeper applications for the lowercase numbers you created."

Su Chen understood as soon as he heard it. They should be exposed to elementary school-level mathematics now.

Only Li Tai is now studying seventh-grade mathematics in junior high school.

"Yes, this lowercase number calculation belongs to the category of mathematics. It can be said that mathematics is endless."

Even if Su Chen graduated from a second-tier university in his previous life, he could not say that he had learned half of it.

Kong Yingda and others were surprised to hear that mathematics is endless.

They are not only good at the Analects of Confucius and the Book of Songs, but also have a high level of attainment in counting rods.

It's just that after they discovered lowercase numbers recently, they felt that the previous counting rods had no advantages.

"Please teach us, sir!" The five people bowed to Su Chen respectfully again and called him sir.

"Hey~ Hey~ Don't be like this, I can't be your teacher. I have books on this subject, and we can learn together."

Su Chen ran around and helped them up. They were all old gentlemen, and they were always bowing to him like this, which made Su Chen very uncomfortable.

The five people looked at Su Chen excitedly, just like children waiting for him to give them candy.

"Everyone, mathematics should be learned in stages. What you are learning now is almost the same as what students under thirteen years old learn.

Only Li Tai, the King of Wei, is learning a higher level now."

Kong Yingda was even more excited when he heard that the addition, subtraction, multiplication and division they had learned now were only equivalent to thirteen-year-old boys.

With the books taught by Su Chen, what level of mathematics would they be?

Kong Yingda had an idea, he wanted to see Su Chen and try to solve a problem with advanced mathematics.

"Su Chen, I have a counting problem, I don't know how to solve it with advanced mathematics, can you show it to us?"

Do math problems? Su Chen thought about it and thought that with their current math level, it shouldn't be difficult for him.

"Mr. Kong, please tell me what the question is and I'll try to answer it."

Kong Yingda nodded, "Su Chen, have you ever heard of pheasants and rabbits in the same cage?"

Su Chen understood that it was just an elementary school math question of chickens and rabbits in the same cage, no pressure at all.

"Mr. Kong, I've heard of this before, and you don't need advanced numerical knowledge to solve this problem, as long as you know addition, subtraction, multiplication and division.

This is a question of logical thinking. Please ask any questions and I'll solve them for you."

Kong Yingda thought for a while and said, "There are 37 heads on the top and 98 legs on the bottom. How many pheasants and rabbits are there?"

Su Chen walked to the blackboard, "This kind of question is very simple. Use the hypothesis method. You can assume that there are only chickens in it. This way it will be easy to calculate.

Each chicken has two legs: 2x37=74.

Because rabbits are counted as chickens, there are 24 less legs. This way you can calculate how many rabbits there are.

24÷2=12, there are 12 rabbits, and the final answer is:

12 rabbits have 48 legs, 25 chickens have 50 legs."

When Su Chen finished speaking, he just finished writing, turned around and looked at everyone, and asked:

"Do you understand what I said?"

Kong Yingda and others opened their mouths wide. This question can be soCalculate? But this answer is correct.

"Su Chen, if we use advanced mathematics, how can we solve this problem?" Kong Yingda did not give up, he wanted to see how this advanced mathematics was used.

Su Chen smiled, turned around and wrote on the blackboard:

2? +4(37-?)=98

2? +148-4? =98

2? =50

? =25

"This question mark is the number of chickens. 37 is the total number of heads, and 98 is the total number of feet."

Everyone looked at the blackboard and thought quietly. In the middle, Li Baiyao asked about the function of the brackets, and Su Chen also explained the calculation order rules in mathematical formulas.

After Su Chen talked for two quarters of an hour, everyone finally understood the most basic problem-solving process of this linear equation.

Su Chen said silently again: 'This lecture thing must never be done in the future. '

I couldn't help but think of Li Tai again, so let him come!

"Su Chen, we are very grateful for your teaching today!" Kong Yingda took the lead, and the other four followed suit.

"Gentlemen, you don't have to be polite, we are just learning together!" Su Chen smiled and bowed.

"Mr. Kong, I wonder if the prince has finished his studies today. I have something to do with him."

Su Chen wanted to stroll around the palace with Li Chengqian, and there was still a big gift that he hadn't given him.

After thinking about it, Kong Yingda smiled and said, "The prince has been studying very hard recently, not to mention that you are a knowledgeable teacher, who is more sophisticated than me and others."

"In the future, if the prince has any doubts about his studies, he can discuss it with us at any time. As for daily lessons, there is no need.

I wonder what your majesty and the prince think?" Kong Yingda bowed and asked Li Shimin.

Kong Yingda thought, he will study mathematics next, who has time to teach you?

After deep thought, Li Shimin said:

"From now on, the prince will study every ten days. As for the rest of the time... I will make my own arrangements."

Li Shimin was not too confident that Li Chengqian would be allowed to go to school, so he decided to leave half of the time and attend classes in the palace on time.

Everyone thought that only half a month of classes was acceptable.

"Your Highness obeys your order!"

"Your son obeys your order!" Li Chengqian was happy. It was great to be able to cut the time in half.
