When Sang Hongyang looked at Xiao Duhou again, his eyes were already full of admiration like a high mountain, which was the existence of the pinnacle of arithmetic.

The basic skills of a businessman are arithmetic.

He prides himself on being the No. 1 master of mental arithmetic in Luoyang, a leader in the business world, and ordinary people don't pay attention to it at all.

However, he learned everything from others.

Xiao Duhou, but he is inventing arithmetic on his own and creating a lot of novelties.

Those are two completely different realms.

In front of the little dusk marquis, he felt that he was just an ant that had descended into the dust, looking up at a giant who stood on the earth and towered into the sky.

Deep down in his heart, his soul trembled with excitement.

This is his lifelong mentor, someone he deserves to follow all his life!

One of the things he regretted the most in his life was to participate in the imperial examination, meet his teacher, and come to study at the Princely College.

...

The first class of Da Chu Princely Academy, a mathematics course at the elementary school level.

Chu Tianxiu only took half an hour to finish these elementary school courses casually.

It's that easy, it's that simple.

Language and mathematics, which are the most important tools and weapons for human development and scientific progress, are used in almost all aspects.

Why teach math first?!

The teenage students of Wanghou College have already completed their Chinese studies in their own private school, so there is no need to start with Chinese.

The rest is the after-school tutoring homework, which is all handed over to the twenty Jinshi teaching assistants who don't understand half of them, to tutor the sixty or seventy young students who are completely confused, to absorb and digest.

Whether you have learned it or not, you will know by doing your homework.

Chu Tianxiu sent out the homework after class and asked them to complete it.

All the jinshi scratched their heads.

As the smartest group of scholars in the Great Chu Dynasty, they certainly had enough brains to learn things.

It's just that the time is too short, and they haven't digested it yet, and they have only understood part of the course, and many questions can't be answered.

However, there are still very few who fully understand.

Dongfang Su and Sang Hongyang are unforgettable, with ten lines at a glance, and almost the whole class is full of eyebrows and dancing, and they are very excited.

"The math invented by Enza is so useful!"

"Yes, the throne is simply a god!"

Numbers and symbols!

Multiplication formulas, addition, subtraction, multiplication and division!

Triangles, circles, geometry!

Formula!

If you take out any of them, you can shock the top mathematicians of the entire Great Chu Dynasty and go crazy for it.

What's more, come up with a bunch of math tools at once.

The two of them felt like poor teenagers who had broken into a grand treasure trove, and they became rich overnight, and they were so excited that they didn't know what to do.

Seeing that the two of them understood, the Jinshi hurriedly asked the two of them for advice, "Brother Dongfang, Brother Sang Hong, how to solve the calculation formula of this circle?" ”

After they have fully learned these jinshi, they will teach the three students they have brought with them.

...

Of course.

Chu Tianxiu, the main teacher, also has three students to tutor after class.

The county lord Li Yu, as well as Di'er and Zu'er.

"Yu'er, Zu'er, Di'er, where do you not understand? It doesn't matter if you don't understand. Come, finish this homework and check it for your husband. ”

Chu Tianxiu is good at guiding and very patient.

All three of them are their own ladies. Let them learn these basic levels of primary school mathematics knowledge in order to keep up with him.

After all, he is a man who wants to lead the progress of science and civilization in the Great Chu Dynasty, of course, he must lead his own lady to progress first.

Li Yu had a bitter face and did his homework after class.

It's so hard!

She looked at the numbers and formulas as if she were reading a book from heaven.

But fortunately, when she learned the art of war before, she had to calculate the logistics supply of the army, so she studied the nine-number calculation for a period of time, and was able to do a small amount of mental arithmetic, and the basic foundation was still there.

The existing mathematics of the Great Chu Dynasty involved nine aspects, including "Fangtian, Corn, Difference, Shaoguang, Shanggong, Average Loss, Equation, Insufficient Win, and Side".

Among the calculations of the "square field", the square and rectangle of the field.

It's just a matter of replacing words and symbols.

Zu'er looked at the after-school homework that she couldn't understand at all, her foundation was even thinner, and she said pitifully: "Uncle, can you not write your homework?" ”

"No, I can't. After finishing this question, I'll give you a break, three times seven, what is it?! ”

Chu Tianxiu said.

"Three, seven... Can I use the calculator to do the math? ”

"No, you have to do mental arithmetic."

"Eighteen? ...！ ”

Zu'er snapped his jade fingers like green onions, and said glutinously.

"Thirty-seven twenty-one! Come on, do it again. Seven times three, what is it? ”

Chu Tianxiu's forehead was bruised, and he rubbed his head and said.

"Seven, three? ... On the contrary, it's much bigger than just now, is it eighty? ”

Zu'er glared at the innocent beauty.

People don't understand, so they can only guess an answer.

"Go and memorize the multiplication formula, memorize it."

Chu Tianxiu almost wanted to vomit blood, completely desperate.

Feelings: He took a lesson, and he hasn't learned anything yet.

I have to teach it again from beginning to end, little by little.

...

The Jinshi really experienced what despair is.

Their foundation is extremely solid, although they didn't understand it at first, but after thinking about it a few times, they quickly figured out what Xiao Duhou's math course was all about.

Homework after class, naturally, is not difficult for them.

However, they still have to let this group of youngsters and girls from the royal family, gate lords, and official eunuchs all learn it, which is simply as difficult as reaching the sky!

It took him half an hour to teach.

But they had to spend four or five hours to make all the princes, boys, and girls understand.

They finally understood that the college's "teaching assistant" subsidy of one hundred taels of silver was not so easy to get.

Wanghou Academy, all day long, all the teenagers jumped chickens and dogs, ghosts cried wolves.

Those gentlemen are in pain!

They have been studying in private schools for more than ten years, and they have never seen such a difficult study.

Shen Xiaomei of the Shen family, Xiao Xiao, the county lord and others, they all cried.

When they were sent to the Princely College by their families, they said that they would come to accompany the prince to study and cultivate a relationship with their future husbands.

Talk about love, talk about love, how easy it is!

Why, it's become a real book?!

The homework in this class is so heavy, they have been studying hard since they entered the academy, and they can't rest for a moment, how can they have time to cultivate a relationship with the prince.

...

In the evening.

Prince Xiang Tiange rode in a carriage and left the students to return to the East Palace.

The young master of the East Palace led more than ten officials of the East Palace, looking forward to it in the East Palace, respectfully waiting for the return of the prince.

Xiang Tiange couldn't help crying when he saw their kind figures.

He finally understood today that the young masters and teachers of the East Palace were too conscientious. More than a dozen teachers taught together, and the lessons were so easy.

Compared to the arithmetic book that Xiao Duhou made up, it was simply too easy.

"Prince, how is it at the Princely Academy?"

The young master asked.

"It's okay, there is Bishop Xiao Duhou, as well as Dongfang Su and Sang Hongyang, two Jinshi to tutor together and learn new arithmetic methods. It's hard, but the effect is excellent. The prince has been able to do mental arithmetic easily, multiplying and dividing within three digits, adding and subtracting. ”

Prince Xiang Tiange said proudly.

Although it was a little hard to learn.

But after I finished studying, I was cool.

Calculations that he couldn't do before, now do the answer pop up with a real brain.

In the past, he had to use a calculation chip to calculate at least one stick of incense.

This great sense of accomplishment is still very intoxicating.

"Prince, please eat quickly. In the evening, we have to hurry up to class, learn the way of the monarch and the minister, the father and son, and the way of reasoning! ... Although Xiao Duhou's set is good, it is still not good if he doesn't talk about the truth of dealing with people. ”

The young master sourly said.

"Still want to learn?"

When the crown prince Xiang Tiange heard this, he suddenly cried with a sad face, and his calves were trembling, "I'm a little weak-legged, young master, help the prince up...!" ”
