The furnishings of the guest house are very simple, but they are also clean and tidy, a bed, a desk, and that's it.

As soon as Ye Qianlan entered, she saw that there were a lot of books on the desk, and there was a Mao suit with the same style as Meng Xiaotian hanging behind the chair.

"You're a student too?"

Ye Qianlan turned her head and stared at Fu Mingyi, the way he was wearing a suit was not at all immature as a student, but his age was also older than a normal high school student.

"Are you an educated youth?"

Ye Qianlan instantly thought of Meng Xiaotian's origin, these two people may have the same experience, maybe they came from the same place.

"Are you here to study or to solve crimes, don't you have this time to take a good look at the mathematical formulas?"

Fu Mingyi spread out the book, took out a pen and paper, and tapped the textbook with the pen.

"Which math formula do you have that you can't remember or can't use?"

"All of them won't ......"

Two pairs of surprised eyes looked over, and the usually bold person instantly shortened his head.

Ye Qianlan looked away, not daring to look at them.

"I'm just a scumbag."

"Then why do you still study? Can't think about it? ”

Meng Xiaotian was puzzled, Fu Mingyi gave him a look, and Meng Xiaotian was so frightened that he trembled.

"Ahem, I mean, why are you embarrassed by yourself, since you can't learn, why are you so reluctant, isn't it too hard?"

"I have my reasons, and I can't explain them to you for the time being."

Ye Qianlan looked into the distance, she didn't want to be full of acne anymore, wasn't it just studying? Although it is difficult, it is much stronger than the ugly eight.

Fu Mingyi glanced at her thoughtfully, and his mood was a little delicate in an instant.

When he jumped down to save people, he didn't think about it that much at all, but the words that those villagers had said, although his left ear went in and out of his right ear, he still heard some of them inadvertently.

Ye Qianlan studied hard because of the son of the village chief?

Thinking like this, his eyes darkened, and the tone of his voice unconsciously became stiff.

"If you can't do anything, you'll have to start from scratch."

"Let's start here, I want to jot down these formulas today, do you have any tips?"

Ye Qianlan let go of the book she had been holding in her arms, and Qian Shaosong's name was written on the page, and Fu Mingyi still recognized it at a glance.

This is the name of the village chief's son?

"Although there is no shortcut to learning, I have summarized a few methods through these years of study."

"How?"

Meng Xiaotian leaned over with a white round face, with a little excitement and flattery on his face.

"You get out, my methods won't work for you."

"How could it be useless? The gap between the two of us in academic performance is there, and I don't have any arms or legs worse than you, so why do I do worse than you in the exam? ”

"The reason why there is a difference between people is because it is different here."

Ye Qianlan finally met a stupid big man, so she naturally wanted to tease him.

"Haha, you're embarrassed to talk about me?"

The honest and honest Meng Xiaotian suddenly smiled unkindly.

"You go out, you go out, you go out for me, your pestle is here to influence my learning."

Ye Qianlan was a little annoyed, anyway, Fu Ming also asked him out, so she simply helped him.

made a few feints, Meng Xiaotian kept dodging back, and when she arrived at the door, Ye Qianlan shook a shot, Meng Xiaotian caught her way, and went out, Ye Qianlan slammed the door and locked it quickly.

She listened to the shouts outside, patted the non-existent dust on her hands, and happily returned to her seat.

"Classmate Fu, that guy was beaten away by me, we can continue to talk about it."

"You're really tough."

Fu Mingyi chuckled, he glanced down at the mathematical formula, and began to explain patiently.

Fu Mingyi tried to tell a formula, did he understand? Ye Qianlan opened her big innocent eyes, shook her head in confusion, and replied very sincerely.

"Nope."

"It seems that not only do you have no concept of mathematical formulas, but you also have no foundation in even the most basic concept of functions."

Fu Mingyi sighed, and could only resign himself to explaining from the beginning.

"Your mathematical foundation is very poor, I can only teach from scratch, let's talk about the concept and three elements of functions today, first talk about the definition of functions: let A and B be two sets of non-empty numbers, if according to a certain certain correspondence f, make for any number x in the set A ......"

Fu Mingyi spoke very seriously, although Ye Qianlan was a little habitual fighting, she still vaguely understood something.

"Will it be?"

Fu Mingyi's saliva was dry, but he found that Ye Qianlan still had the initial confusion in her eyes, although he had only been with her a few times, he had already begun to understand her character.

If you know, you will definitely get stuck, but if you don't say anything, you won't.

Fu Mingyi resigned himself to his fate and asked again: "Will it be this time?" ”

Fu Mingyi's throat and eyes were a little smoky, mainly because he was angry, he had spoken in such detail and seriousness, why didn't the person in front of him open his mind?

"It's going to be a little bit more than last time."

Ye Qianlan was a little more confident.

Get!

Isn't this answer just not thorough? Since he took over this porcelain job, Fu Mingyi could only accept his fate and continue to talk about the topic.

After talking five times in a row, Ye Qianlan finally nodded.

"I will, this time."

"Alright, let's get to the point."

After Fu Mingyi's explanation, Ye Qianlan found that the mathematical formulas that she had no clue about before had formed some rules in her mind.

"It's ......"

After Fu Mingyi finished speaking, Ye Qianlan felt that she was about to understand, but it was still a little close.

"I still don't understand."

The same formula, Fu Mingyi took the trouble to talk about it three times.

Ye Qianlan suddenly showed ecstasy in her eyes, she grabbed Fu Mingyi's arm and asked loudly.

"So the definition of function equality: if the definition domain of two functions is the same, and the correspondence is exactly the same, we call the two functions equal, right?"

Ye Qianlan asked excitedly, and when she turned around, she found that Fu Mingyi was staring at the back of her head in a daze.

"I will, I'll write this formula down for you."

"It's useless to just be silent, you still have to say it."

Fu Mingyi came back to his senses, and as soon as he opened his mouth, it was another blow. Ye Qianlan tugged at the corners of her mouth, quite a little unwilling to admit defeat.

"Let's just talk about it, isn't C called the independent variable, the value range A of x is called the definition domain of the function, and the value of Y corresponding to the value of x is called the function ......"

Ye Qianlan said something like that, and Fu Mingyi's face looked better.

It took an hour before and after, and it was finally a small achievement, and it was not in vain that he still had a sore throat, otherwise he would have already passed the voice change period, and if he continued to toss like this, he would have been sent away because of the teaching question at a young age.
