The book has no strength, the female supporting role just wants to survive

"This question can be answered using the 'Equal Method': after 63 days, the duck flew 9 times, the goose flew 7 times, and the two flew 16 times in total. Therefore, the two flew once in total, that is, the first encounter took 1/63 days."

Jiang Tunan's voice attracted the attention of the male students from the nearby Juyuan Academy, and many of them stopped writing and looked over here.

"What you said makes sense, but we haven't even learned the Qi Tongshu..."

Everyone in Yuhuayuan looked embarrassed, but Jiang Tunan remained calm and just smiled.

"It's okay. Qi Tong Shu is just a general method. I have a simpler method."

The content of Qi Tongshu at the beginning was similar to the common denominator of fractions in current math classes, and later it was expanded into a method of dealing with ratios. In fact, Jiang Tunan didn’t understand it very well, she just randomly applied the formula.

"She has an easier way?"

"real or fake?"

The people in the nearby Juyuan were whispering, but Jiang Tunan was not affected. Instead, he was immersed in his lecture.

"In addition to the method of equality, we can also use the method of hypothesis."

Jiang Tunan picked up the brush and started drawing on the paper. Lan Ying thought at first that Jiang Tunan was showing off, after all, people of different levels often do this kind of thing. But when she saw Jiang Tunan's serious look, she kept silent.

"Assume that the distance between the South Sea and the North Sea is 1. Let's assume an unknown number A. That is, on the day A, the duck and the goose meet. The distances that the duck and the goose can travel each day are 1/7 and 1/9 respectively. The distance that the duck and the goose can travel each day multiplied by the unknown number A is 1. In this way, we can solve for the unknown number A, which is 63/16, or and ths."

The eyes of the people in Yuhuayuan gradually brightened, and a faint voice came from the crowd.

"I think I understand a little bit..."

“Although I have never heard of such a method, it sounds reasonable.”

Those who were sitting close to Yuhuayuan in Juyuan had already heard Jiang Tuanan's explanation. After Jiang Tuanan gave the answer, they went to find someone who knew the answer to verify it.

"That's right! It's exactly what she said!"

"She can do it, too?"

The people in Juyuan were whispering about Jiang Tunan, and the center of the discussion - Jiang Tunan, suddenly felt bored. After all, he was a college student, and now he was showing off in front of a group of people who might only have an elementary school level of math. It was really bullying.

"Ms. Jiang? Could you please repeat the method you just mentioned to set up unknown variables?"

Someone in the chrysanthemum courtyard mustered up the courage to approach, with a hint of pleading in his voice.

"can."

The man seemed to have not expected Jiang Tunan to agree so readily, and his words began to stutter.

"Really? Can I ask my friends to come along?"

Jiang Tunan nodded. She was still very happy to do something to help others within her limited ability.

The man from the Chrysanthemum Courtyard brought a few of his friends to the Chrysanthemum Courtyard, and seeing this, he also spoke tentatively,

"Can we come and see?"

"If you can squeeze in, come and see."

As soon as Jiang Tunan said this, many people from Juyuan gathered in the aisle next to Yuhuayuan. Seeing that the aisle was still some distance away from Jiang Tunan's position, the people from Yuhuayuan took the initiative to give up their seats to the people from Juyuan, and squeezed together with the people next to them.

"Come closer, please."

"Thank you!"

When Jiang Tunan saw this scene, he couldn't help but sigh in his heart, it turns out that this world cannot do without girls!

"Why don't you come up to your seat over here?"

Behind Jiang Tunan were many empty seats in Xiyun Courtyard, but even so, the people from Ju Courtyard and Yuhua Courtyard did not think of moving to these empty seats.

"That's someone else's seat. We can't sit there."

In fact, the people in Xiyun Courtyard are all children of officials. Although their family members' official positions are not as high as those in the previous two levels, they are officials after all. The people in Juyuan and Yuhuayuan are all ordinary families, so naturally they dare not occupy the position of Xiyun Courtyard at will.

Jiang Tunan expressed her understanding. Even if she wanted to help others, she had no right to give up other people's positions, so she didn't say anything else.

People from the two courtyards were crowded in the same place. Jiang Tunan still sat in his seat and explained the questions to others. After all, the people from the Ju Courtyard had a basic foundation, so they accepted Jiang Tunan's explanation very quickly, but the people from the Yuhua Courtyard were much slower.

“Why did this place become like that?”

Someone from Yuhuayuan asked the person next to him in a low voice, but it was obvious that the person next to him didn't quite understand either.

"The law is long in reality, and the meaning is also the same, that is, if the numerator and denominator are multiplied by the same number at the same time, the overall value will not change, and vice versa."

The person who spoke was from Kikuin, and the people around him also explained,

"Sometimes when calculating between fractions, you need to use this method to make the denominators the same, so that you can just add or subtract the numerators."

"Thank you. Thank you."

They all smiled at each other, thinking the same thing in their hearts:

The people in Yuhuayuan (Juyuan) are quite easy to get along with.

But they immediately sensed that something was wrong with the atmosphere, because Jiang Tunan's lecture in front of them suddenly stopped.

Several people turned to look at Jiang Tunan, only to see her looking at them with a touched expression.

"This scene is so loving that it makes me want to sing a song!"

Jiang Tunan slowly closed his eyes, clenched his left fist and placed it on his chest.

"This is the call of the heart ~ This is the dedication of love ~ This is the spring breeze of the world ~ This is..."

Everyone:...

"Friends in the back, can you please wave your hands?"

Everyone: Maybe not.

Perhaps the atmosphere became awkward, so Jiang Tunan had to stop singing.

"Ahem, let's continue with the topic."

......

Xiao Mingrui stayed in the wing of the Imperial College specially provided for the students of Lanyuan to rest for a while before slowly walking towards Shanyan Hall. However, just as he reached the door, he saw men and women gathered in Yuhuayuan, doing something unknown.

"So this is a linear equation with one variable. One variable means there is only one unknown number, and linear refers to the square numbers involved. If I have time later, I will tell you about linear equations with two variables..."

Xiao Mingrui was a little surprised. The voice seemed to be Jiang Tunan's?

Jiang Tunan is giving a lecture?

"Class time is almost up, everyone please go back to your seats."

Jiang Tunan reminded them that people from other courtyards would be here soon. If there were too many people, they might be seen by someone with ulterior motives and cause gossip.

"Thank you Miss Jiang for today."

"Thank you."

"Thank you..."

Almost everyone in Juyuan walked up to Jiang Tunan, bowed and thanked him. Only after thanking him did they return to their seats.

Jiang Tunan nodded in response every time. After going through the whole process, she estimated that the people in Juyuan would suffer from lumbar disc disease, and she herself would suffer from cervical spondylosis.

"Um, I'm sorry for getting angry at you this morning. It was wrong of me..."

Lan Ying from Yuhuayuan spoke softly, with a sincere apology on her face. Several women around her also spoke up.

"I'm sorry, I was prejudiced against you and yelled at you."

"I'm sorry Miss Jiang, please forgive me..."

Jiang Tunan was actually a little confused, because she had no idea who was the person who was throwing a tantrum in the back this morning. For a group of people who were dressed the same and whom she didn't know, she thought everyone looked the same.

"It's just a small matter. I think you are much braver than most people in this world because you are willing to admit that you are wrong."

Jiang Tunan: I must be very handsome now.

But Jiang Tunan's image didn't last long before he was interrupted by Xiao Mingxu who ran in.

"Xiao Nannan! Are you okay? I heard you were beaten up by a group of people?"
