Chapter 129 You Give Me a Question

Ye Wan originally thought that Yang Ting was just curious and just browsed through it, but she didn't expect that he kept looking there, and sometimes he was meditating and sometimes thinking, as if he was really studying.

Seeing him like this, I couldn't help but want to laugh a little. Getting started is very difficult, and you must have a teacher in front of you to guide you.

However, Yang Ting looked at it on his own, and he still read it with great interest. Could it be that he really understood it?

And it took so long to see.

This time Ye Wan was quite surprised.

Couldn't help asking: "You understood everything just now."

"I understand a small part of it." Yang Ting said modestly, after all, this is just a book, and you will only know how well you are studying in the exam.

"Do you really understand? Then what don't you understand? You can ask me." Ye Wan said seriously.

If Yang Ting is willing to learn, she doesn't mind teaching him.

"No need, you've worked so hard, why bother you again, let's do your work first, I'm just playing around." Yang Ting said.

"It's okay. I've been watching for so long and I'm tired. I can answer your questions and relax a bit." Ye Wan said.

Hearing Ye Wan's words, Yang Ting finally took out the book and sent her the doubts just now.

"I don't quite understand this part."

"What? Statistics!" Ye Wan was dumbfounded when she saw the book. He must have done it on purpose. This statistics is an optional subject and it is difficult to learn.

To be honest, I am not very good at statistics. This is not advanced mathematics, and people who are not in a special profession rarely learn this.

Although it is very useful, but because it is too difficult to learn, teachers in school do not take the test, and naturally they do not teach much when teaching.

However, these basic things can still be understood.

Afterwards, he told Yang Ting about it.

"When the correlation coefficient is higher than [-]%, it will show a positive correlation..." Ye Wan explained to Yang Ting.

"Oh, I see." Yang Ting nodded and said.He can understand a little bit now, and he will understand soon.

After that, I read all the knowledge in the book from beginning to end.

By the time everything was finished, it was already two hours later.

"Have you finished reading?" Ye Wan asked in a daze.

"Well, these things are quite simple."

"You are too incredible. Do you dare to let me test you?" Ye Wan asked.

"Okay, you can come up with a question, I just want to test what I have learned." Yang Ting said to Ye Wan.

"Then I won't be polite." Then he said casually, "You write down the derivative formula first."

The derivation formulas of derivatives are the most basic knowledge, and these basic formulas are also the key steps in solving problems. If you can remember all these things and use them flexibly, you will get twice the result with half the effort when solving problems in the future.

However, after raising this question, Ye Wan felt a little regretful.

Although the knowledge is very basic, after all, Yang Ting only watched it for two hours, and from the first year of high school to the third year of high school, how could he remember these formulas.

"Would you like to change the topic?"

"No, just use this."

Then, pick up the paper and pen on the table.

Soon all those derivation formulas were written out.

Wrote a full half page.

Ye Wan, who was watching, widened her eyes.

"Your memory is too amazing. You actually memorized all these formulas in such a short time just now? You are really amazing. It's a pity that you dropped out of school at that time."

"Why don't you come up with another question?" Yang Ting said.

"You still want to try? That's good." Seeing that Yang Ting still wanted to try, Ye Wan asked another question.

It is a question about the geometry of space.

The questions are also relatively simple.

However, for this topic, normal students have to think for a minute no matter what, but what surprised her was that Yang Ting wrote immediately after that topic, without any time to think.

"You should think twice before you do the questions, you will easily suffer losses if you do this." Ye Wan reminded from the side.

Yang Ting ignored Ye Wan's reminder and continued to answer the question.

The speed of writing is also very fast, and the knowledge of space geometry is also used.

In just 5 minutes, all the questions were done. This speed is definitely the speed of those top students!

Read it once and know the answer immediately!

However, how could this speed appear on Yang Ting?
"You must have studied this before, right?" Ye Wan asked.

Yang Ting smiled.

He said to Ye Wan, "Why don't you give me another question to try?"

"What? You still have to try? Well, I'll help you, but this time it won't be so easy, you have to be mentally prepared."

Seeing that Yang Ting didn't stop, Ye Wan was also aroused to be competitive.

Then, he said to him: "This is still the problem, can you do it with vectors?"

Seeing that Yang Ting didn't speak, Ye Wan couldn't help but ask: "How is it? Do you know the difficulty of this question? Although it is very simple, the college entrance examination is not such a simple thing. Otherwise, wouldn't everyone be the same? College Students."

Yang Ting didn't speak, but smiled calmly again. For some reason, when she saw Yang Ting smiling, Ye Wan's heart skipped a beat, because she was infected by his smile!

This kind of smile makes people look like there is no pressure at all, as if you don't need to worry about anything after you leave the matter to him.

"Then I'll try again." Yang Ting said.

Then, I picked up the pen on the table and started to answer, without any derivation and checking process!

This situation made Ye Wan feel very shocked. You know, even if she is doing this problem, it is impossible for her to do it so quickly. The middle checking process also needs several steps.

However, he just wrote it all out without any hindrance, as if the answer was in his mind and he just copied it down.

Ye Wan was completely shocked by this, she had seen people with a good memory, and he had seen people with a good understanding, but both memory and understanding are so good, this is too heaven-defying!

"Take a look, right?" Yang Ting picked up the paper and handed it to Ye Wan.

Ye Wan hurriedly picked it up, the more she looked at it, the more shocked she became!
These are all correct, and they are completely written in the format of the textbook. The steps that should be simplified are not complicated at all, and the steps that should be detailed are not simplified at all. Then, after comparing the answers, they are completely coincident. This...how is this possible?

Ye Wan was completely shocked.

I wouldn't believe it was real if I hadn't seen it with my own eyes.

No!wrong!There must be a problem!

He must have been exposed to these things before, otherwise how could he be so powerful!

Then, another paper was drawn from the pile of papers.

"This is a college entrance examination question, known as the most difficult question in five years, do you dare to give it a try?" Ye Wan asked.
