City: My grandpa is super rich

Wow~~

Everyone in the classroom was in an uproar!

"How is this possible, this kid took only thirty seconds from getting the quiz, walking back to his seat, and then walking to the podium!"

"Not all of the quiz this time are multiple-choice questions, and Meng can't finish it so quickly!"

"It is estimated that I knew that I could not pass the eighty points, so I simply gave up on myself."

Shen Jianhai glanced at Xu Feng, and then began to score.

Immediately afterwards, the expression on his face began to change.

First indifference, then dismay, and finally incredible!

Some students couldn't help but ask curiously, "Teacher, how many points did he score?" "

"Full marks!"

Shen Jianhai felt that his throat was a little dry!

This quiz is a topic that he personally wrote, so he knows how difficult it is to get a perfect score!

Not to mention doing all the topics in such a short time.

Even he can't!

If it weren't for the fact that he had written this quiz last night, he would have even wondered if this guy had gotten the answer in advance!

The classmates were also shocked!

"One hundred points? It can't be! The quiz was only an hour long, and I couldn't even finish all the questions! "

"I didn't expect Xu Feng to be a top student!"

"Where is this Xueba, it is simply Xue Shen!"

At this time, Shen Jianhai found a question and asked, "Xu Feng, why did you only write the answer under each question?" What about the problem-solving process? "

Xu Feng shrugged, "It's too simple, the mental arithmetic will come out." "

For example, there is such a topic in the quiz: a store buys a batch of jeans at a purchase price of 100 yuan each, and the demand function of this product is Q=400-2P (where Q is the demand and the unit is jump; P is the sales price in yuan). Q: What is the selling price to get the maximum profit?

And in Xu Feng's eyes, it was automatically translated like this:

Bob has two apples and ate one, how many apples does he have now?

Where else is the problem-solving process, read the answer to the question and pop up on your own.

Hearing Xu Feng's words, many students almost vomited blood in depression.

Lao Tzu solved a problem and cost a few pieces of scratch paper, and as a result, your kid's mental arithmetic came out!?

Shen Jianhai pushed his glasses, his hands trembled a little, and he said, "You wait, I'll give you another question." "

Then he picked up the chalk and swiped a question on the board.

He still didn't believe that Xu Feng could finish and do all the topics so quickly.

Not to mention mental arithmetic!

So he was going to be on the spot! Personally! Question!

This problem is still a bit difficult, even if a college math teacher has to solve this problem, it will take some time.

"You try to solve this problem."

Shen Jianhai turned around and handed the chalk to Xu Feng.

At the same time, he said to the students below, "Don't be idle, let's solve it together." This question is still very difficult, mainly because it contains a lot of knowledge points, interlocking with each other, and there are..."

"Teacher, I'm done."

A voice sounded behind Shen Jianhai.

This voice immediately attracted the attention of all the students.

Shen Jianhai turned back in amazement, and saw that a "6" was written under the title.

"What about your closing process? Mental arithmetic again!? "

Shen Jianhai was about to collapse.

Xu Feng nodded shyly.

Shen Jianhai took off his eyes in a hurry, and his heart had already set off terrifying waves.

"The old man is not angry!"

"Is this kid really doing the right thing?"

"And mental arithmetic!"

"I didn't expect that there was a math prodigy in our class!"

Xu Feng said, "Teacher, I can go back and sit." "

Shen Jianhai pointed outside the door and said in a deep voice, "You, get out!" "

The crowd froze.

Isn't it appropriate to praise two sentences according to the development of the plot.

Xu Feng not only got a full score in this quiz, but also mentally calculated a difficult problem, why didn't he let him enter the classroom?

Even Xu Feng himself was dumbfounded.

At this time, Shen Jianhai suddenly smiled, and the expression on his face softened.

"There is no point in you continuing to take my classes, and I can't teach you anything, so in the future, you can take my classes as you like, depending on your mood."

Once again, the classroom was boiling.

"I'll go! Learning God is worthy of studying God, and there is even this privilege! "

"Hell it! This is the first time I've seen the old man smile! "

Later, under the envious and jealous gaze of everyone, Xu Feng hummed a small song and went out, enjoying this privilege with peace of mind.

"You wait."

Not long after walking out of the classroom, Shen Jianhai chased out from behind.

"Teacher Shen, do you have anything else?"

Xu Feng asked.

Shen Jianhai said, "I will say it bluntly, you are a rare mathematical genius in ten years, if you are willing to study, you will definitely achieve greater achievements, and I can also help you introduce to famous teachers." "

Shen Jianhai's heart for talent flooded, especially after seeing Xu Feng.

Xu Feng smiled slightly and said, "I'm sorry Teacher Shen, I'm not interested in this." "

"But you just said you were fascinated by calculus last night..."

Before he finished speaking, Shen Jianhai looked stunned, and he understood something in his heart.

How can a person who is not interested in mathematics read books and become fascinated?

Although Xu Feng lied, Shen Jianhai was not very angry. Everyone's mind and talent are different, and naturally they cannot be constrained by a unified standard.

Sighing, Shen Jianhai shook his head and went back, muttering in his mouth, "Hey, it's a pity, there is one less new star in the mathematical world..."
