Son, how did you become the richest man in elementary school?

The average middle school student can finish it in an hour and a half, which is not bad, but the elementary school student in front of him only took 15 minutes!

That's right!

This...he doesn't know the standard answer, does he?

But soon, Liang Sining shook his head. The third-year middle school students had just finished this test paper, and many of them hadn't even got their grades yet.

It is simply impossible to have a detailed answer!

What the hell is this kid...

Liang Sining glanced at Gu Xiu, although he was extremely horrified in his heart, but he was an old teacher after all, so naturally he would not be easily seen by others.

At this time, after a careful look, Liang Sining wanted to tell the kid in front of him not to be too crazy about the solutions to the next few questions:

"The last question, your idea of ​​solving the problem is not bad, but there is actually a simpler way to solve the problem, do you know?"

Unexpectedly, Gu Xiu nodded, "I know."

"Know?" Liang Sining frowned: "Young people can't talk nonsense, if you know, why don't you use it?"

"This is a junior high school test paper, and I also use the knowledge points of junior high school. In fact, if this question is answered with the formula of high school, it will be easier and simpler."

Gu Xiu replied with a slight smile.

But Liang Sining froze in place. He didn't expect that this kid would use his junior high school knowledge to answer the question on purpose.

But before he doubted it, he saw that Gu Xiu had already opened the draft book, and sure enough, he saw on the next page that he had already written out the answer method using high school knowledge to answer the question.

And, pretty standard!

Although it only uses the basics of high school knowledge points, it can be seen from Gu Xiu's problem-solving thinking that the child's thinking is very clear and his purpose is also very clear.

This can only mean one thing.

At least, the high school knowledge that Gu Xiu used is really integrated!

This discovery did not make Liang Sining feel frustrated, on the contrary, his heart was burning with enthusiasm, even a smile appeared on his face:

"I heard that you have learned high school knowledge by yourself, tell me how much you have learned by yourself?"

"In fact, I have almost learned the knowledge of high school by myself. I have already completed all the knowledge points in science." Gu Xiu blinked:

"For mathematics, I'm currently teaching myself calculus."

"Cough cough...!"

Liang Sining was choked, and his whole body coughed violently, but he still suppressed the discomfort in his throat, and asked in a weird voice:

"Calculus? Isn't that university knowledge?"

"Although many knowledge points in high school are interesting, I feel that advanced mathematics is more useful and convenient, so I learned it in advance."

This……

Liang Sining was speechless for a moment.

He stared fixedly at Gu Xiu, extremely serious, as if he wanted to see the lack of confidence and evidence of lying in the eyes of the child in front of him.

But it's a pity that Gu Xiu's eyes are only calm and confident, and there is no cowardice at all.

He didn't lie!

What he said was true, and it was even possible that what he said had reservations!

Even Liang Sining felt that this thought was outrageous when it came to his mind.

After all, advanced mathematics is not that simple.

This is not something that can be easily learned by yourself by simply reading a book.

Because in fact, the things in the advanced mathematics textbooks are all jumping, and there is no one to guide them, so it is impossible to learn them just by reading the textbooks.

Many people even feel dumbfounded after reading the textbook.

Even college students.

It is also rare to pass the textbooks and learn the knowledge points that have not been learned directly by self-study.

How could this seven-year-old child do it?

"I don't care about advanced mathematics for the time being. Since you said that you have learned all high school mathematics, then do this test paper." Liang Sining thought for a while and took out another test paper.

This test paper is also a unified test paper.

But the difference is that this test paper is a math test paper for the third year of high school!

Same as before, Gu Xiu didn't say anything, just took the test paper, sat in his seat, and started to read the questions and answers.

This time Liang Sining didn't cook anymore.

He moved a stool and sat beside Gu Xiu, keeping his gaze fixed on Gu Xiu.

He wanted to see how this kid did the questions.

But this look.

But let him determine an unbelievable thing.

This seven year old...

Really, it's a monster!

Chapter 132 Three Questions, Liang Sining's Excitement

"How is your speed of doing the questions so fast?"

"These questions are too simple and not difficult, so it's normal to hurry up, teacher."

"Then don't you need to think about it?"

"I've been thinking about it. Ever since I saw the question, I've been thinking about the answer to the question. You see, I have to pause for a while every time."

"The pause you said means a pause of one or two seconds for each question, and then write the answer on it?"

"Yeah, what's wrong with that?"

"There's nothing wrong with this, it's just that I understand the multiple-choice questions so quickly, but the answers to the questions, several of them are not easy, right?"

"The difficulty of answering the questions is indeed a bit higher, especially the first answer question, but in fact the main difficulty lies in the fact that there are a lot of invalid information in the question, so the key is that as long as you can understand the question, it will be much easier."

"What about the last question, how did you come up with this solution?"

"Actually, at the beginning, I used the knowledge points of high mathematics to look at it, but then I thought that the college entrance examination seemed to be unable to use university knowledge, so I started to think about the answer method of high school knowledge points again, but when I was answering, I thought of Actually, there is a slightly simplified solution, so I wrote it down.”

Chat here.

Liang Sining felt a bit unable to continue the conversation.

There was no way, he felt that his years of knowledge and experience were completely useless in front of this child.

Because of this seven-year-old child.

horrible! ! !

Originally, he had always thought that Ji Tiantian might be exaggerating, even if Ji Tiantian said that she saw with her own eyes that Gu Xiu did five-year college entrance examination and three-year mock test papers, and her grades were very good.

Liang Sining was always skeptical.

After all, most seven-year-olds would be considered pretty good if they could recognize all the characters. Even if they were really geniuses, they might have mastered all the knowledge in elementary school at most.

As for middle school and high school.

Many of the knowledge points are obviously not easily grasped by a seven-year-old child.

Not to mention university knowledge.

But now.

Not only did Gu Xiu make the test paper, Liang Sining even found that when Gu Xiu was doing the test paper, he didn't stop at all.

It's as if you know the answer immediately when you see the question, and write on it in a hurry.

Even for a few seconds, Liang Sining thought that it was not a seven-year-old child who was doing the test, but a teacher who gave the paper.

In this case, there are only two possibilities.

The first one is that Gu Xiu already knew the answers, and he memorized all the answers by rote, and then wrote them down.

This is obviously impossible.

Not to mention this set of test papers, there is no answer at all, and even if there is an answer, it is absolutely impossible for Gu Xiu to think that he will test him today, let alone memorize such an answer.

That leaves only the second possibility.

Gu Xiu, he has thoroughly understood all the knowledge points on this test paper!

This is even more outrageous than the first possibility!

But the problem is that the facts are in front of us at this moment, even if it is outrageous, it seems to be true.

Moreover, Liang Sining watched Gu Xiu do the questions.

Even what Gu Xiu wrote in the draft notebook, he saw it with his own eyes.

It can be seen clearly.

When Gu Xiu was doing the questions, he was really thinking, and then came up with the answer.

He really mastered high school knowledge!

Even, the university's advanced mathematics knowledge has already mastered a lot!

Put away the test paper.

Liang Sining looked at Gu Xiu again, the horror in his eyes could no longer be hidden.

Shock, surprise, astonishment.

But more, it is ecstasy!

It's like a master of hand-carving, encountering a piece of uncut jade that is natural and does not even need to be over-carved.

Such joy even made Liang Sining's excited hands tremble:

"good good good good!"

"Gu Xiu, you are a genius. I believe now that you have really mastered the knowledge of junior high school and high school!"

"Tell me, to what extent have you mastered advanced mathematics?"

"This..." Gu Xiu seemed to think about it for a while: "Actually, most of the knowledge that needs to be learned in the university has a little understanding."

"All the advanced mathematics you need to learn in college?" Liang Sining's eyes widened:

"you sure?"

Gu Xiu nodded: "Well, I have read all the advanced mathematics in the four years of college, and I probably understand Yidiandian."

If it was before, when Gu Xiu said this, it is estimated that the old teacher would have slapped Gu Xiu without hesitation, and directly rubbed Gu Xiu on the ground.

Nonsense is not.

Although the advanced mathematics that universities need to learn can only be regarded as the simplest in the field of mathematics.

But this is also a high number!

This is also knowledge that many college students can't understand even if they think about it.

A seven-year-old said he had it all.

What about trouble?

But at this moment, looking at Gu Xiu's bright eyes, Liang Sining just took a deep breath and nodded:

"I'll try to see if you've really mastered it, and I'll make a question for you to do."

"Good teacher!" Gu Xiu nodded obediently.

Liang Sining didn't hesitate any longer, took a new math homework book, thought about it and began to write on it.

It doesn't matter what Gu Xiu said is true or not.

As long as you do the question, you can immediately check the authenticity.

The first question appeared soon.
