Zhou Yong, male, 18 years old, is a senior in high school.

Half a month ago, his father died of cerebral congestion, looking at his mother who washed his face with tears every day, at that moment he seemed to have suddenly grown up, holding books and nibbling on books every day.

It's a pity that his academic performance is mediocre, and he is about to take the college entrance examination, so it may be too late to hold on to his feet now.

By the last month, most of the teachers at the school were mainly answering questions and not giving many lectures.

Zhou Yong looked at the 98-point math test paper in front of him and smiled mockingly.

Possible...... He's going to have to repeat it, right?

But his father died, and only his mother was the breadwinner, could he really afford him to repeat his studies for a year? And can he do well in the exam if he repeats it?

Zhou Yong was in a dilemma, he rubbed his face with his hand and entered the study area, he had seen the video of the first up master fairy tale Yan Yan, but he was sorry...... Maybe he doesn't have enough brains and doesn't feel like he understands much.

Zhou Yong was bored with the latest release, and his eyes fell on an ID named "Everyone has God", and the ghost sent God to enter.

This ID is so arrogant, if he can God University, he kneels down and calls this up lord dad!

This learning video didn't even show the teacher's face, but a pair of hands!

In the video, a neutral voice came from the non-argumenting male and female: "One of the college entrance examination points I want to talk about today is function. If you don't even understand this, I don't recommend you repeat it, I advise you to start in elementary school. ”

Zhou Yong: "??? ”

- who gave you the courage to speak like that? Is it really not dissuaded?

Zhou Yong looked at the test paper in his hand and wanted to scold his father, if he could understand it, he would only score 98 points?

It's only half an hour, just listen to it, he wants to see which newcomer is so dragged.

"The known function f(x)=ax...... I'll only talk about this topic once. Forget it, if you don't understand, you don't have to go to elementary school and rebuild it. First ......"

The closer he got to the college entrance examination day, the more impetuous Zhou Yong became, and he couldn't listen to it at all, but he didn't know why he suddenly listened to it......

"That's what it did! I understand. Zhou Yong subconsciously shouted.

Suddenly, it dawned, and suddenly it didn't seem to be very difficult.

Zhou Yong became interested, and he wanted to continue watching, and the video ended.

Zhou Yong: "??? ”

It just ended without saying goodbye? Where did the newcomer come from to hang like this?

If he used to think that the function of this type of problem was a mountain, now it feels a bit like a simple 1234......

Zhou Yong's eyes suddenly lit up, and he decisively paid attention to this newcomer UP master, and left a message: "Thank you, teacher, please continue to make such videos, I understand." ”

Because this is a newcomer, the interface for sending gifts has not even been opened, otherwise Zhou Yong would not like to give this newcomer more than a dozen gifts as tuition.

In order to verify whether he had learned this function question type, Zhou Yong quickly found seven or eight questions of the same type from the workbook.

Half an hour later, Zhou Yong saw that the math problems he had made were exactly the same as the standard answers, and a stream of tears welled up from his eyes.

For a moment, Zhou Yong suddenly felt ...... It may be useful to cramm.

The traffic of the salted fish video app is quite large, and many students have seen this video through the "latest release......

After reading it, everyone had the same idea - ahhhhhh

Big guy is awesome!
