If you don't work hard to farm, you can only be a wealthy young grandmother

Chapter 237 Yan Yan Has No Interest in Him

Ling Zhi had already stood silently on the sidelines watching the show, who grew up in a pair of pants, who doesn't know who?
Brother Xiaofan, the ancestor of the fox is about to attack, you have to hold on.

At least, don't be so quick to defect.

I didn't watch any dramas.

Xie Fan struggled for a while:
"Then tell me first."

Is Qin Yefei the kind of person who can do whatever he wants so easily?

of course not!

I found an example from the textbook:
"As for this question, you first use the method taught by your brother Qian Zheng to solve it.

I will teach you how to solve it later. "

"Okay, if your method is not as awesome as you said, don't cry!"

cry?
This word has not existed since Qin Yefei was three years old.

"Understood."

Xie Fan took back his textbook, lay on the front of the jeep and started to solve the problem.

I have to say that the teacher Qian Zheng is very capable.

It is possible to teach a primary school student who has never been to junior high school to be like this. Although the process is difficult to understand, both the process and the answer are correct.

After explaining it, Xie Fan straightened up:
"Hey, it's over."

Qin Yefei raised his wrist:

"3 minutes."

"what?"

"It took you a full three minutes and ten seconds to solve this problem."

Xie Fan glanced:

"So what? I figured it out, didn't I?"

Qin Yefei shrugged:

"It is solved, but it takes 3 minutes to solve a problem, and it is the simplest example of trigonometric functions. If this is a more difficult problem, how many minutes do you plan to spend?"

This.
Xie Fan froze. He really hadn't thought about this question. For Xie Fan all along, he only needed to get the final answer right, and he didn't care much about the rest.

But when Qin Yefei said this suddenly, Xie Fan was a little touched.

"Then, why not?"

Qin Yefei hooked the corner of his lower lip again, without any need for textbooks or pens, and started dictating directly:
"The biggest problem with the trigonometric function you just solved is that you didn't really understand the simplest and basic concepts.

For example, sinA represents

How can such a simple thing be remembered? "

Xie Fan was no longer as arrogant as before, and he was hit hard.

This man was right, he just seemed to make simple things more complicated.

Fortunately, Qin Yefei didn't intend to continue preaching, and it was almost enough.

"Give me the pen."

"Oh."

Not only obediently gave the pen, but also the notebook.

Then I saw Qin Yefei scribbling down two formulas in his notebook.

"Memorize this formula to death."

Xie Fan caught the notebook thrown over, glanced at what was written on it, and stared at Qin Yefei for a moment, then looked at Qin Yefei, wanting to speak.

However, Qin Yefei had already opened the door and got into the car.

Roll down the window:

"Children, I will come here often in the future."

The implication: If you still have any questions that you can't solve, just come to me, and don't go to Brother Qianzheng.

Did he teach as well as he taught himself?

After the car left, Xie Fan also prepared to leave, instead of going to the educated youth dormitory that he wanted to go before, he turned around and headed home.

As for the car that has already left Xiejia Village, Ling Zhi joked in the car:

"Brother Ye, are you like this?"

"otherwise?"

"Hey, Brother Ye, I didn't say that you absolutely can't do this. Look at that educated youth who understands so much!"

Ah.

The man in the back seat glanced at the rearview mirror, then said coldly:
"Yan Yan has no interest in him!"
