Unknowingly, when it was time for class, the child sent Yuan Baoer to the door of the classroom.

Yuan Baoer went in and found that someone was already there.

The man had his back to the door, busy with something.

Yuan Bao'er was a little curious, and walked over to see that there were many wedges scattered on his desk, and he was trying to combine the wedges into a whole.

But I don't know where something went wrong, and it always disperses quickly.

The man was stubborn and never gave up.

There were a few footsteps from the side door, and Yuan Bao'er remembered that she was peeping like this, and it was really not a gentleman's doing.

She hurriedly sat upright, looking ahead.

In a moment, an old man in a dark ochre robe walked in slowly.

I think it's a gentleman who teaches arithmetic.

Yuan Bao'er hurriedly straightened her waist and waited for the roll call.

I didn't want the old man to just glance at her, so he leaned next to her, "Fan Li, do you have a clue?" ”

Fan Li stood up and said, "Students still need some time. ”

The old man opened his eyes and asked Yuan Bao'er, "You have only been watching it for a long time, do you have a clue?" ”

Yuan Bao'er hurriedly got up and made a move, with a dry smile on her face, saying that people can't do it after studying for so long, she wants to say yes, why don't you slap the face of her classmates, how will she get along in the future?

The old man frowned, and his face was unhappy: "Yes is yes, no is no, what are you laughing at?" ”

"The mountain chief said that you are very smart, and I only allowed you to come over, isn't what you said false? I can first explain that there is no way out of my discipline, and if I don't succeed, I should quit as soon as possible, otherwise I will not be able to run away from a failed subject. Don't cry when the time comes. ”

was so ruthless, so contemptuous, it made Yuan Bao'er's smile burst.

She pursed her lips and looked to the side, Fan Li nodded politely at her, "If the lady has an opinion, you might as well say it, and you and I will refer to it together." ”

There were some slight creases on his brows, and some blue and dark under his eyes, but his lips were kindly upturned, and he was probably not annoyed.

Yuan Bao'er's heart moved, and she said in a low voice: "There are indeed some immature ideas. ”

Fan Li's eyes lit up, and he hurriedly moved a large area to the side, signaling her to be as free as she pleased.

Yuan Bao'er glanced at the old man, made a gesture towards Fan Li, and sat down.

When she saw it, she had some ideas, but she didn't know if it was right or wrong if she didn't get started.

After fiddling like this for a while, she managed to put together a flat surface.

Fan Li was very curious, took it over and took a closer look, and found that the way she arranged the wedges was very different from herself.

He sighed and tried to add more.

Yuan Bao'er didn't care about him, and took the others to fight the other side.

The old man was a little dissatisfied because he was forced to stuff a female doll by the mountain chief, but he didn't expect that this female doll did have some skills, so he also came over to take a look.

Yuan Bao'er quickly spelled out nine extremely irregular planes, and she repeatedly combined the planes, but she never got the point, and couldn't help but suspect that her idea was wrong.

Fan Li suddenly pinched a wedge and pointed to one of the grooves, "Why don't you connect these three sides together?" ”

Yuan Baoer glanced at him and pushed the plane to him.

Fan Li pinched the wedge, spliced it, and sure enough, it was connected.

One passes, the others pass, and soon, there is a strangely shaped sphere on the table.

The two raised their eyes to look at the old man, and the old man finally smiled slightly, "That's all for today's class, Fan Li, this is your junior sister, she has just entered the school, and you will know what you learned earlier." ”

The old man stroked his beard and walked away with the ball.

Yuan Bao'er looked at Fan Li blankly.

That's it?

Fan Li has studied here for more than a year and knows his style very well. “

"Mr. Gao's teaching is used to like this, and it is the tradition of calculus that the senior brother leads the younger brother, and the generation leads the generation."

After speaking, he took out a stack of books and came out, "This is what I used to record with reference to the codex of my senior brothers, and it is also mixed with my simple opinions, you can take it back and take a look." ”

Yuan Bao'er was a little surprised, "You were ready early in the morning?" ”

Fan Li smiled, "Mr. Gao told me before that he wanted to have a little junior sister. ”

"Calculation requires talent, the guidance of predecessors is not assisted, Mr. Gao acts differently, so our senior brother will take on the responsibility of guiding the calculation."

When Yuan Baoer heard this, she hurriedly thanked her.

Fan Li waved his hand, "If you can be included by Mr., you are your own family, so you don't need to be so polite." ”

Yuan Baoer is as good as a stream.

Fan Li got up to leave, and when he saw that Yuan Bao'er was holding it too hard, he said, "I'll help you." ”

Yuan Bao'er said yes with a smile and went outside the academy with him.

chatted while walking, and only then did I know that Fan Li was born in a noble family, and now the Fan family where the third son is an official, and he has no intention of taking the imperial examination, and is dedicated to studying Gewu.

The purpose of studying calculus is to study the subject better in the future.

Fan Li was curious about why Yuan Baoer practiced calculus.

This kind of thing is really boring for a little lady, and almost no lady wants to study this.

Yuan Baoer fell in love with him, and did not hide it, so she said her thoughts.

Fan Li was very surprised, "Do you know how extensive the land of Daqing is, how can you achieve it with your own strength?" ”

Yuan Bao'er smiled, "I can't do it alone, but thousands of farmers can." ”

Fan Li's eyes widened, and he looked at her in disbelief, "You want to teach the farmers all over the world?" ”

Yuan Bao'er smiled, "It's not necessary." ”

She gave the example of a shop, "Who doesn't like to buy good things, and if they can buy something that is far better than a penny for a penny, they are not happy?" “

"If you use it with a gift, one will pass ten, ten will pass hundred, and you will naturally know it."

"But it takes time and means."

Fan Li sighed, as if he was a little admired.

"The little junior sister behaved unusually."

Yuan Bao'er smiled embarrassedly, "It's just my stupid idea, and I'm just thinking about it at the moment, if I really want to do it, I don't know how to do it, senior brother, just listen to it." ”

"If a junior sister can have this ambition, she is better than many sons," Fan Li felt that Yuan Bao'er had a lot of ideas, and she dared to implement them.

The two chatted all the way to the door.

Cui Xin and Zhang Da were waiting there early in the morning, and they were surprised to see her come out with so many books.

Yuan Bao'er put her things at ease and asked Fan Like if she still had classes.

Fan Li nodded, seeing the strength of the two of them, he couldn't help but think of himself.

Since he was a child, he has been very interested in Gewu, and he has talented brothers above him to stand up for him, and there is no pressure of scientific research at all, so he studies Gewu with his temperament.

Now after listening to Yuan Baoer's words, he seems to have just woken up to the fact that he may be able to do something.

On the other side, Yuan Bao'er had already flipped through his notes.

Fan Li's notes are very detailed, and they are marked on the side to mark which book they are studying, which one is the source, and what needs to be paid attention to.

Yuan Baoer deliberately searched for the Ten Classics of Arithmetic, which she was more familiar with, and looked at the content on it, and found that she had some ideas, which coincided with it, and some of them diverged.

She jotted down the points of disagreement, and when she got home, she copied out the part.

Prepare to go to Fan Li in the next class.
