Daiyu: After being reborn, who still wants to be a yandere?

Before coming to the Ye family, Xia Meng was also feeling uneasy.

Because she sat at the same table with Liao Qiuxia, she would often complain to her about how bad Daiyu's grades were.

Even tonight, when Liao Qiuxia and she were leaving school together, Yang Liushu sent her a message asking her to ask Daiyu to solve a math problem. Liao Qiuxia even mocked her:

"Don't waste your time. Everyone knows Lin Daiyu. Look, she got zero in math. It's a joke to ask her to teach you math.

And did you listen to Yang Liushu? He himself failed the math test, and he followed another failed test to find another zero? Save some time. "

Before Daiyu provided them with the steps and ideas to solve the problem, Xia Meng was still wondering if the willow tree was crazy and how could Lin Daiyu solve the problem.

However, she was working with Lin Daiyu to sell rose saltpeter, and she thought she also needed to go to the Ye family to better understand the production process and procedures of her products.

When Xia Meng saw Daiyu casually writing down the steps to solve the problem on a piece of draft paper, she looked puzzled: What are these?

"Sister Lin, what exactly does this string-and-leg method mean?"

"You don't understand this?"

Yang Liushu rolled his eyes at Xia Meng, then happily took out the complete collection of mathematical formulas that He Zimo had given him.

This book of formulas not only contains the most complete mathematical formulas and theorems today, but also the famous "Nine Chapters on the Mathematical Art" in Chinese history.

Yang Liushu explained to Xia Meng seriously:

"Multiply the hypotenuse and the leg by themselves, add up their products, and then take the square root to get the chord, which is chord = (hypotenuse2 + leg2). Xia Meng, doesn't this look familiar to you?"

Even Chen Ziyi was not quite clear about what the Xiangu method meant.

He was actually a little embarrassed to ask, so before the study session, he introduced himself to everyone. Everyone knew that he was a doctoral student at Yunnan University.

Moreover, he had just learned that Daiyu was a student at Nancheng No. 6 Middle School, and Chen Ziyi was deeply skeptical about her identity as Lin Heitu.

After Yang Liushu's explanation, Chen Ziyi asked uncertainly:

"Willow, is this the Pythagorean theorem you are talking about?"

The willow tree proudly snapped its fingers at him and replied:

"Yes, the doctor is indeed the doctor."

Xia Meng only then realized that the willow tree now was no longer the same willow tree as before.

When a man has been away for three days, he should be treated with new eyes——

This person, who was at a similar level to me a few days ago, is now very good at playing with various theorems.

Daiyu praised sincerely:

"Liu Shu has made great progress in the past few days. What he said just now is correct. The chord-leg method is a theorem mentioned in China's Nine Chapters on the Mathematical Art. In modern mathematical language, it is called the Pythagorean theorem."

Daiyu's praise made Yang Liushu even more proud. He even wrote a few lines in classical Chinese:

"Xia Meng, do you know what the art of surplus and deficiency, the art of the present, and the art of decline are?"

Listening to Yang Liushu asking these questions, Xia Meng was really confused. She couldn't even figure out the Pythagorean theorem, so it would be impossible for her to learn mathematics using such flowery language.

Xia Meng was completely confused, her eyes were clear and silly, she looked blank and didn't know how to start writing.

Daiyu obviously noticed her embarrassment and comforted her:

"It's okay, take your time, don't put too much psychological pressure on yourself, those theorems are just tools, they are to be used, not to learn the obstacles on the road."

Xia Meng said with a bitter face:

"But I really don't understand what Liu Shu said. Mathematics is so boring. It's just a bunch of formulas and theorems! It's so annoying. Mathematics is so cold and emotionless!"

Daiyu asked Yang Liushu to lend the book of mathematical formulas to Xia Meng, and consoled her earnestly:

"There is no emotion in mathematics. Mathematics is the most delicate and soft. Look, aren't the numbers in these orders created with our hard work?

If you can't do it, you can try to do it first according to the ideas I provide you.

Solving math problems is not difficult. You can treat it like painting. First, trace it, use other people’s methods, and use the examples in the textbook to understand it. Then, use your own ideas and thoughts to create. "

After saying that, Daiyu reworked the question on the test paper and every small question, lowering the difficulty, simplifying the amount of calculation, breaking down each step, and then asked Xia Meng to do it first.

Xia Meng's problem is similar to that of Yang Liushu, in that both lack a solid foundation in theorem.

The difficulty of today's test paper was originally lower than before, and Chen Ziyi actually found some ideas for solving the problem.

However, competition questions are competition questions after all. It is said that three cobblers are better than one Zhuge Liang. What's more, those questions were set by a group of Zhuge Liangs in the competition organizer.

Therefore, it is quite difficult to solve all the questions in just one or two hours.

When Xia Meng was studying on the side, Chen Ziyi also followed along to listen. After all, his foundation was much better than that of these high school students. He followed Daiyu's thoughts and suddenly understood.

He was very excited, but then he realized that he had preconceived ideas, and his attitude became humble and submissive.

**

The next day, the weather was clear and the sky was as blue as water.

Today is Daiyu's first monthly exam since she came to this era.

This exam is a city-level joint exam organized by the Nancheng Education Bureau and led by No. 1 Middle School.

Nancheng No. 1 High School is the best high school in Nancheng City and the only first-level standard school in Nancheng City.

The Education Bureau hopes that No. 1 Middle School can serve as an example to other schools and lead them to make progress together.

As the leading middle school in the city, No. 1 Middle School has always looked down upon the city-wide joint examination organized by them. They believe that No. 1 Middle School is simply allowing the lower schools to get the examination paper resources for free.

Therefore, the teachers of No. 1 Middle School have been making requests to the city, demanding the cancellation of the city-wide joint examination.

No one wants to help the poor students out of poverty!

Every time the test papers are prepared, the teachers are from No. 1 Middle School. They deliberately raise the score of the joint examination papers so that the lower schools will give up.

The city finally agreed to No. 1 Middle School that if no students from other schools could rank among the top 100 in the city this time, the joint entrance examination would be cancelled.

This exam is set strictly according to the time of the college entrance examination.

It is still the first semester of senior year, and except for No. 1 Middle School, senior year courses have not yet ended in other schools. Allowing these students to be ranked in the top 100 is almost equivalent to directly persuading them to drop out.

The first exam is Chinese.

We are all Chinese and we all use Chinese, so Chinese is the subject in which it is most difficult to create a gap among all subjects.

The Chinese teachers at No. 6 Middle School all have a pretty calm attitude.

In the classroom, there is the sound of "rustling", the tip of the pen touches the draft paper to answer questions.

The Chinese teacher of Class 1 went to Class 6 to invigilate the exam.

Although the students in Class 6 are studying science, they are generally from well-off families and their families spend a lot of money on their tutoring outside, so they even fail in Chinese.

However, this is a test paper issued by Nancheng No. 1 Middle School. It does not test the normal state, but only the abnormal state.

After the exam, a group of students wailed and cried:

"Why are all the questions in classical Chinese? After one question, another comes up. I'm really going to cry!"
