Zhu was concerned about the results of Zhao Jingli's consultation.

However, she was afraid that her daughter would be overly concerned, so she did not ask Zhao Ruxi directly. Instead, after Zhao Ruxi went to Beining the next day, she called Nanny Yuan to ask about her situation.

Grandma Yuan recounted the conversation between several people yesterday.

Mrs. Zhu knew that Zhao Ruxi was good at arithmetic. She was very happy when she heard from Nanny Yuan that Zhao Jingli's arithmetic talent was recognized by Zhao Ruxi.

But after hearing that Zhao Ruxi changed her mind and stopped teaching Zhao Jingli arithmetic, she frowned: "Brother Li made Sister Xi unhappy?"

"The old slave didn't notice that the girl was unhappy. The girl also said that she wanted to ask the math teacher in the academy for the eldest young master, so that the math teacher could accept the eldest young master as his student. It can be seen that she was not angry. It was probably because the eldest young master was dissatisfied with the girl's arithmetic skills.

It's not as good as the gentleman in the academy. The girl saw it and said so."

Grandma Yuan's heart was partial to her own girl, and she didn't want Mrs. Zhu to think that Zhao Ruxi was narrow-minded, so she even gave Zhao Jingli some eye drops.

The girl in her family was so busy, but she still found time to teach the eldest young man painting and arithmetic. The eldest young man not only burst into tears with gratitude, but also disliked the girl for not being good at arithmetic. Grandma Yuan was very unhappy in her heart.

Zhao Jingli knew that Aunt Yuan thought about him so much, and he would scream that she was wronged. He did not dislike Zhao Ruxi, he only sighed in his heart that the arithmetic teacher at the Women's College was great.

Although Mrs. Zhu has feelings for Zhao Jingli, her heart still favors her biological daughter. Her thoughts are similar to those of Grandma Yuan.

She said: "Sister Xi is so busy that she doesn't even have time to sleep. She is so tired and thin. At first, she just did painting. No one can replace her. Now that Brother Li wants to learn arithmetic, he naturally has to learn from Mr. Arithmetic.

You've learned well. If the second wife can't afford Shu Xiu, I'll do it for him personally. There's no need to trouble Sister Xi with this matter."

"Yes." Grandma Yuan felt relieved when she heard what Zhu said.

The madam still takes care of the girl.

Although the eldest young master is also pitiful, it is all his mother's fault and has nothing to do with the girl.

Because of this, he has enjoyed the treatment of the prince of the original Hou family for more than ten years and has made a lot of money. Now, the uncle, his wife and the girl are still willing to look after him and find ways to help him, which is a great blessing for him.

Don't ask for too much, otherwise you will be greedy and the snake swallows the elephant.

The next day, Zhao Ruxi went to Beining and made a special trip to the academy. He found the arithmetic teacher and mentioned the matter of Zhao Jingli to him.

She said: "I have tried him, and he is quite talented in arithmetic. At least he is not stupid enough to make you angry when you try to teach him. Can you please be tired and teach him?"

This arithmetic gentleman's surname is Gan, and his name is Gan Lun. He is also sixty-seven years old. He was originally a doctor in the Ministry of Household Affairs, Zhejiang Province. His arithmetic ability is also very famous.

Good students are given preferential treatment in front of their teachers, and Gan Lun was particularly fond of Zhao Ruxi, so Zhao Ruxi dared to make such an excessive request directly to the old gentleman.

"Teach your brother?" Gan Lun raised his eyes and glanced at Zhao Ruxi. He casually pulled out a piece of paper and handed it to Zhao Ruxi. "You solve this problem and I will promise you this."

Zhao Ruxi was helpless: "Master, can't you change your routine?"

"That's not possible." Gan Lun said seriously, "Haven't you heard that a new trick can be used all over the world? You don't have to worry about old tricks, as long as they work. Hurry up and do the questions, don't be wordy."

Zhao Ruxi had no choice but to sit down, take out her charcoal pen, take a piece of draft paper, and read the question.

After reading the question clearly, she looked at Gan Lun with an even more helpless expression: "Master, where did you get the question? It's so difficult, I can't do it."

"If I can't do it, I can't agree to your request." Gan Lun didn't even raise his head, "If I have time, can't I have a drink and have fun with my old friends? I have to suffer from this."

Zhao Ruxi gritted his teeth.

She knew that the old gentleman did it on purpose.

Ever since the old man discovered that she was very good at arithmetic, he started this exam mode.

He didn't know where to find these questions, so he tried every means to get her to solve them, and he promised some benefits, such as a unique paperweight, famous dishes from a certain restaurant, etc.

She could afford these things herself and didn't care about them. But the white-haired teacher wanted to play this bounty game with her, and she couldn't bear to refuse, nor could she bear to let the old gentleman down.

When she sees old gentlemen like Gan Lun and Kang Shilin, she will think of her modern mentors.

The old man treated her as his own daughter, even more so than his own daughter who had lived abroad for many years. She was gone, and the old man didn't know how sad he would be.

She couldn't bear to refuse, but she couldn't show off too much, so she played this game with Gan Lun at the rate of solving one problem out of three.

This was so bad that the old gentleman got more and more aggressive and caught her doing questions every time they met.

So today, Zhao Ruxi was also prepared to solve the problem.

After seeing the title clearly, she thought about it for a while, then took a pen and started calculating on the scratch paper.

She originally wanted to delay it for a while so as not to appear so powerful. But after a meal, she had to attend a training class, and the old man also had a class at the North Campus.

She had no choice but to finish the questions at normal speed.

This was an old question left over from the Ministry of Finance, and Gan Lun actually didn't know the answer. Seeing that Zhao Ruxi had done it and looked very relaxed, he was shocked in his heart, but his face was completely calm.

He put on the attitude of a teacher testing students and said: "To know what is happening, you must know why it is happening. Please tell me how you solved the problem."

At first, Zhao Ruxi was a little confused when Gan Lun asked her this question because she didn't know how to explain the source of her answer.

Later, she read through all the arithmetic books of Jin Dynasty that she could find, and she had a firm understanding of the arithmetic level of this era, and then she became calm.

The arithmetic level of the Jin Dynasty is not low, equivalent to the level of the Ming Dynasty. Queen Shengyao published several arithmetic books after time travel, giving a rough introduction to the mathematics content of elementary school, junior high school, and high school, and even mentioned calculus.

.

But she probably couldn't remember it, or she didn't understand it thoroughly, or she was already in her old age when she wrote these books, she was suffering from illness, and she was mentally depressed. The theories she mentioned were relatively general, and many of them were not explained clearly.

The mathematical symbols commonly used in modern times are still used in it. If she didn't teach it personally, everyone would read her mathematics book as if they were reading a book from heaven.

After Queen Shengyao finished writing the book, she personally taught her two grandsons. However, the two grandsons were either not talented enough or were not focused on it. The two learned only a little bit about it, and because of their status, they did not learn the skills.

What they learned spread.

Soon after Queen Shengyao died of illness, her arithmetic books had to be explored by Jin scholars themselves.
