Su Yang returned the book to the shelf.
By the way, I glanced at the previous book on the shelf.
He found that many books have changed in value after he read this book.
For example, the value of "Algebra" by sergelang has risen directly from 5 to 25.
There are also some books whose value has decreased, such as "Multi-Analysis Visualization Method", the value has dropped from 10 to 8.
It seems that the evaluation value is based on Su Yang's current ability and obtained after a comprehensive judgment.
This saves Su Yang a lot of trouble when looking for books.
Not to mention improving a lot of efficiency, but also faster to upgrade mathematics ability.
In less than three hours, Su Yang's experience value has reached [90/100].
Only ten points of experience!
Su Yang randomly selected a mathematics book worth 10, then returned to his seat, ready to upgrade it to the elite level in one go.
As soon as he opened the book, Su Yang plunged into the ocean of knowledge.
Swim and swim~
So that the beauty next to him poked Su Yang twice, but Su Yang didn't feel it.
"Classmates, classmates?"
Chen Lingling poked Su Yang with her finger in a low voice.
"what?"
Su Yang was awakened and raised his head regretfully.
Who broke Xiaoye's interest!
Haven't seen others watch it right away!
Su Yang searched for the target, but found a petite girl sitting next to him.
The other party has an oval face with a light makeup.
In the freezing winter, he wore a jk out of season.
It may be because of the coldness, a purple sweater cardigan was added to the upper body.
The black hair is like a waterfall, hanging down to his waist very quietly. It is the air bangs that Su Yang likes very much.
The whole person is only about 1.5 meters, belong to the kind of typical pocket girl, can't wait to be rubbed into her arms to protect.
Even if disturbed, Su Yang asked politely: "Is there anything I can help?"
"Emmm, it's like this. I will take a postgraduate entrance examination next year and my math is relatively poor. Can you ask a classmate a question?"
Chen Lingling's crisp voice is very beautiful, which makes any normal man unable to refuse.
It turned out to be a senior sister!
"Of course you can, just say it."
Su Yang smiled, and said in his heart what happened.
"This is a proof question for seeking the limit of a sequence of numbers. I can't understand this step. I have watched it for a long time..."
Speaking of the back, Chen Lingling's tone was full of grievance and helplessness.
Who made her a sad postgraduate entrance examination candidate?
It happened that she hated high numbers the most. She could have learned seven or eight points before, but the more you get behind, the more you can feel the teacher's full malice...
Hey, no way.
I have to go down the path I chose with tears in my eyes.
"This question is obviously a routine question. Just follow the problem solving steps of the definition method and write it down, like this..."
As Su Yang explained, he wrote and painted on the draft paper.
A few strokes pointed out the other party's problem.
The question just now became clear in an instant, and Chen Lingling immediately understood the essence of this question.
"The so-called understanding of one question, you can understand one type of question. There is only one type of this type of question, which is contradictory, but the method of solving the problem is similar."
With that said, Su Yang also added a counter-evidence question to the other party.
A question is rather complicated, and the answer is given in seconds.
Chen Lingling's eyes gradually changed from disbelief to shock, and then to joy.
She saw that Su Yang had been reading books related to high mathematics before, so she asked with the mentality of giving it a try.
In fact, don't say it's a classmate, it's the kind of mathematics who teach Niu X to give her lectures, she may not understand it.
No way, the old mathematics is difficult.
Sometimes, if the foundation is not solid at all, it will lead to a lot of questions that are not understood.
When teachers talk about topics, they tend to ignore the fact that students' basic knowledge is not solid.
When Su Yang was lecturing the topic, not only the steps were simple and easy to understand, but she also expanded some basic knowledge points for her.
Chen Lingling's eyes were instantly full of worship.
Unexpectedly, this way can catch a wild mathematics boss!
