Abandoned daughter takes charge of the family, so rich that even the best people can't envy

Left Prime Minister Wei Zhen waved his hand and said, "Let me do it.

One hundred steamed buns for one hundred monks. Three senior monks have no one to fight for, and three junior monks share one. How many buns does each senior monk have?

Song Jinxiu was speechless: This should be an ancient math Olympiad problem. These old men really think highly of her.

She glanced at Zhou Kunran and saw him staring at her without blinking. She smiled and asked, "Can you calculate?"

Zhou Kunran: "You want to get the answer from me? Don't say I don't know. Even if I do, do you think I can tell you? Don't expect to cheat."

Song Jinxiu sneered. Do I need to cheat on elementary school students' math problems?

She said aloud, "Twenty-five senior monks and seventy-five junior monks."

She doesn't even need to calculate this problem.

Everyone quickly looked at Lord Wei, and when they saw him nod, they all took a breath.

Right again.

If you guessed the first time, what do you say this time?

Left Prime Minister Wei Zhen narrowed his eyes and asked, "How did you calculate that?"

Everyone looked at Song Jinxiu. Yes, she didn't write or use an abacus, so how did she calculate it?

"You must have cheated." Zhou Kunran pointed at Song Jinxiu with a firm look on his face.

"If you had written and drawn for a while, I might have reluctantly believed you. But Prime Minister Wei had just given you the question, and you knew the answer without even doing any calculations? You must have known the answer long ago, to be able to say it so quickly."

Everyone looked at Prime Minister Wei suspiciously.

Wei Zhen said angrily, "Impossible. I got this question from the only copy in my family. It's impossible for it to be passed on to others. I haven't told anyone about it."

Even he himself took him half a year to figure it out.

Song Jinxiu sneered, "Cheating? Why don't you give me a try?"

Everyone: Yes, besides Lord Wei, who else here can solve this problem?

I don’t know how to do it, so who can I cheat with?

Lord Wei?

Are you kidding?

If Lord Wei could cooperate with you in cheating, he would not be the Left Prime Minister!

Song Jinxiu gave Zhou Kunran a cheeky smile and beckoned, "Come on, spread some paper and ink for me, I'll teach you how to calculate."

Zhou Kunran was so angry that he blew his beard and glared: "You arrogant boy, can you bear it if I grind ink for you?"

The emperor said, "My dear Zhou, among three people, there must be one who can teach me. If Song Jinxiu can do arithmetic again, we can learn from her. It will be worthwhile to sharpen the ink."

Song Jinxiu smiled and said, "Ah, Your Majesty is wise. Today I will be your teacher. Lord Zhou, please grind the ink."

Damn old man, I told you to pick on me right away and look down on women? Humph!

The emperor had spoken, and Zhou Kunran dared not disobey. He had no choice but to come over to grind ink reluctantly with a pale face.

Song Jinxiu picked up the pen and her small regular script characters appeared on the paper.

There are four algorithms

Through these days of practice, her calligraphy has become more and more sophisticated.

Although he is not a master of calligraphy, he is still considered a top-notch calligrapher. His calligraphy gives people a fresh and refined feeling at first glance.

Song Jinxiu smiled and said, "There are four algorithms. I wonder which one Lord Zhou would like to learn?"

Zhou Kunran was so angry that he pointed at her and said, "Stop playing tricks. If you can come up with one method, you win. You even came up with four. How shameless!"

Song Jinxiu glanced at him, stopped talking, and waved her hand:

The first one is the hypothesis method...

The second method is the method of system of linear equations of two variables...

The third method is grouping...

The fourth method is the diagram method...

Those who can become high-ranking officials are not useless. They have a vague understanding of the first method, and the second one, about a system of linear equations of two variables, is so confusing that everyone is like reading a book written in a foreign language.

Song Jinxiu looked at it and asked: What? The equations are already listed, and these people are still staring at each other.

What does it mean? Don't understand?

“My Lords, this is the grouping method, which is the simplest and most clear.

一个大和尚和三个小和尚分为一组，每组分得四个馒头。因此可以分为100÷4=25组。每组中有一个大和尚和三个小和尚，所以大和尚的数量为25人，那么小和尚的数量为25人x3=75人。

Oh, of course, you can also do 100-25=75, understand?"

"Huh? This 100 means one hundred? This 75 means seventy-five?

Now I understand what you said.

Oh my, oh my, it can be solved like this? Why didn’t I think of it?

Song Jinxiu: She forgot that people here don’t know Arabic numerals.

Left Prime Minister Wei Zhen clapped his hands and praised repeatedly.

The Minister of Industry stared at it, "Yes, yes, I understand. It's so easy for Miss Song to do it. No wonder, no wonder, I was blinded by one thing."

Both of them were the top scorers in the imperial examinations.

They both praised it like this, let alone others.

Left Prime Minister Wei Zhen suddenly said, "Wait a minute, Miss Song, you know the Great Dao Nine Causes Art? Who are you? No, where did you learn the Great Dao Nine Causes Art from? Who is your master?"

The Nine Causes of the Great Dao?

Everyone was shocked.

Let’s look at the mysterious symbols on the paper together.

"Assuming all of them are monks, we'll need 3 x 100 = 300 steamed buns..."

Could it be that 3x100=300 is the Nine Causes of the Great Dao?

and also:

x + y = 100

3x + y/3 = 100

No wonder they couldn’t understand it, it turned out that he was using the Nine Causes of the Great Dao?

It is said that the Nine Causes of the Great Dao was a mathematical method created by ancient astrologers and has long been lost.

Nowadays, everyone uses abacus and memorizes abacus formulas.

The Nine Causes of the Great Dao? The emperor looked at Song Jinxiu, his eyes full of inquiry.

He had already investigated the girl's background. She was a peasant girl who had been forced to leave her family and had only just come to prominence.

It is said that he was the disciple of Guiguyu.

If it is related to Xuantian Sect and has some unique abilities, it can be explained.

Looking at the little girl's bright white teeth and high spirits, he couldn't help but feel fortunate that this genius was one of his people in Cangwu.

The emperor couldn't help but feel admiration for his talent!

Song Jinxiu glanced at the emperor and said, "Your Majesty, my master said his name cannot be told to anyone else."

The emperor smiled and said, "Then I won't say it."

Song Jinxiu then said to the Left Prime Minister Wei Zhen: "I'm sorry, old sir, the emperor won't let me speak."

Everyone: ...? Is this okay?

Zhou Kunran was also shocked. He felt that he had been the clown all day long.

But since he was able to become the third-rank Minister of War, he was naturally able to bend and stretch.

He laughed heartily and said, "Congratulations, Your Majesty! Congratulations, Your Majesty! Your Majesty is blessed with great fortune. Cangwu has gained another remarkable talent. After my testing, this little kid has proven to be generous and strong, worthy of becoming a master of mathematics."

He said that targeting was to help the emperor test, and Song Jinxiu curled her lips: Are all officials so shameless? It is really shameless, and there is no one in the world who can defeat them.

The emperor laughed.

"My dear ministers, if anyone has a vacancy, please tell us and let's see what position our first female official in Cangwu should take."

Everyone looked at Song Jinxiu with joy and eagerness.

The Nine Causes of the Great Dao, a mathematical prodigy! And also the art of color painting and oil pressing—of course, such talents should be recruited regardless of their background.

The Ministry of Revenue and the Ministry of Works were guarded by Qian Dai and Lu Qiao. Naturally, there was another struggle.

The Minister of Rites said, "Your Majesty, Miss Song is a girl after all, and she is too young. It may not be appropriate for her to be an official, but her talent cannot be buried. How about letting her teach at the Imperial College for Girls?"

The Minister of Rites carried Song Jinxiu on his back and curled his fingers towards the emperor, making a nine gesture.

What it means is to let her teach the Nine Causes of the Great Dao.
