Monument Yangmen

Chapter 43

The next morning.

Yang Yansi took Cao Wei and the three little guys into Bianjing city noisily.

Crossing the streets and alleys, when they arrived at the gate of Taixue, the group of people felt a little silly.

There are too many people, shoulder to shoulder is no longer enough to describe, it can be said that people are crowded and hugged.

Yang Yansi stopped a passerby who was in a hurry to join in.

"Brother, why are there so many people today?"

"Don't mention it. Since Taixue was founded, a challenger finally appeared and won two games in a row. Everyone came here because of the reputation, and wanted to see the demeanor of this master Yang Qi who is both good at chess and calligraphy. Who knows, too The school actually sealed the door and didn't let everyone in to watch the battle. So we can only block the door."

"I won't tell you anymore, I have to squeeze forward again to see if I can meet Young Master Yang Qi."

Yang Yansi was a little confused, since when did he become known as a master of both chess and painting?

"Zizizi~" Cao Wei looked envious, "Brother Qilang, so many people adore you. You are simply better than Su Qiniang."

"Who is Su Qiniang?" Yang Yansi asked.

Cao Wei said bluntly, "The number one oiran in Bianjing."

"Boom~" A chestnut was knocked on Cao Wei's head, and Yang Yansi cursed: "If you don't learn well at a young age, you will be beaten."

The gate of Taixue was blocked, and Yang Yansi's carriage naturally couldn't get in.

A group of people squeezed through the crowd.

When he squeezed to the entrance of Taixue, Yang Yansi's clothes had already been twisted, crumpled and completely devoid of the image of a talented man.

At the gate of Taixue, Dr. Taixue was already waiting, and when he saw Yang Yansi, he welcomed him in.

Under the leadership of Dr. Taixue, Yang Yansi and his party walked to a side hall.

There are not many people in the side hall, but everyone is a person with a reputation and a relationship.

Yang Yansi's father, Yang Ye, and his older brothers had military affairs today, so they couldn't be there.So She Saihua was appointed to cheer for him.

She Saihua held Yang Yanqi, who was carved in pink and jade, in her arms, and looked at Yang Yansi cheerfully.

"Mother, why are you here?" Yang Yansi was also a little surprised.

She Saihua said with a smile: "The military affairs in the north are busy, your father and your brothers are so busy that they are dizzy. When I left in the morning, I specially asked my mother to come and cheer for you."

In the Song Dynasty, it was difficult for ordinary women to enter the hall of elegance.

However, She Saihua is not an ordinary woman.In addition to the status of the fourth-rank imperial wife that Yang Ye won back for her, She Saihua herself is also a guerrilla general appointed by the emperor.

Although he is not in charge of the army, he is also a unique existence in the world of women in Bianjing City.

Yang Yanqi turned around in She Saihua's arms, facing Yang Yansi, raised her small fist and shook it.

"Brother Qi, come on!"

Yang Yansi pampered her and scratched her nose, and said with a smile: "Let's see how Seventh Brother can beat them."

In the middle of the side hall, Shen Lun stood in the middle, wearing a long gown and white clothes. On his left stood Taixue Jijiu Wang Qin, and on his right stood a thin young man aged 27 or [-].

"This old man will introduce you. This is Chu Yan, the prime minister of Qin Tianjian, who is also responsible for assessing your arithmetic."

Under Shen Lun's introduction, Chu Yan cupped his hands slightly, "Shen Xianggong invited me to come over to assess you, and I don't intend to say too many polite words. I asked three arithmetic problems, and you will pass the test if you answer them."

Yang Yansi looked at Chu Yan suspiciously.

Taixue has changed his gender, don't plan to send some old monsters to embarrass himself?
It seems that it is quite fair for Shen Lun to be the host!

However, why did Taixue invite a person from Qin Tianjian to assess himself?

Yang Yansi knew very well what Qin Tianjian was doing, and the people living in it were a group of magic sticks.

Suspiciously glanced at Wang Qin, seeing the sinister smile on his face, Yang Yansi felt that this matter was far from simple.

Get the question from the waiting waiter, open it and have a look.

Yang Yansi was a little dumbfounded.

first question:
Today there are seven parcels of the upper grain, one dou of the real one, two parcels of the lower grain, and ten buckets of the real;Ask about the geometry of upper and lower grains?
An ancient version of linear equations.

For example, a linear equation in two variables is a linear equation.

Yang Yansi has an impression of this question, and this question can't help him. He has seen this question in "Nine Chapters of Arithmetic".

The second question:
Today there is a tree that is two feet long and three feet in circumference.Ge gave birth to his lower body, wrapped around the wood for seven weeks, and the upper body was even with the wood.Ask Ge Changge?

Pythagorean questions, that is, the geometry questions of later generations.

All of a sudden, Yang Yansi felt that the person who wrote the question was very good.

This kind of simple geometry and equation problems is nothing in later generations. Many predecessors have proved some theorems in these problems, and the two problems can be easily solved with the theorems.But in ancient times, this stuff was unusual.

Yang Yansi has always believed that the mathematics level of the ancients should be around the level of the fourth grade of elementary school.

It wasn't until this moment that he realized that he was inferior to the ancients, and he had obviously reached the junior high school level.

In fact, many well-known mathematical formulas at home and abroad have been proved and used by our ancestors a long time ago.

However, in the long history, it was gradually forgotten.

Confucianism has dominated the mainstream market for a long time, and mathematics has not been developed. Therefore, many mathematical classics that our ancestors have worked so hard to research have been destroyed.

Many scholars in later generations confirmed it through classics.Many well-known foreign theorems were discovered by our ancestors hundreds of years earlier than foreigners.

It's a pity that even though there are historical books to prove it, in the textbooks, the formulas and theorems still use the names of foreigners.

What surprised Yang Yansi the most was the third question.

The third question does not have too much text, it is simply a picture.

A geometric arrangement of triangles.

"Yang Hui Triangle?!"

The geometric arrangement of the binomial coefficients in the triangle looks immature, and there are many loopholes.

But Yang Yansi can confirm that this is indeed the 'Yang Hui Triangle' without a doubt.

Chu Yan has been watching Yang Yansi's expression from the side, seeing that he was shocked by the triangle diagram he made, so he explained something dryly.

"I'm still in the verification stage for this topic, and I haven't deduced the correct conclusion."

"You let me do it without a correct conclusion?" Yang Yansi couldn't help but growl.

Chu Yan still had a dry expression on his face, "My lord Wang told me that I must come up with a question to stump you..."

The corner of Wang Qin's mouth twitched.

You can die if you are not upright?
Yang Yansi was a little puzzled, "You really researched this thing yourself, didn't you copy it from that book?"

Chu Yan was obviously taken aback, shaking his head.

"This is a pattern I discovered in my spare time, and I still find it recorded in that book..."

Yang Yansi searched for the only historical knowledge left in his mind.

Suddenly opened his eyes wide.

He knows who this guy is...
