In the library, Liu Yichen was immersed in the sea of ​​topics.

"Liu Yichen, you know that you are still here at this point. Congratulations, you will lead the team to defeat three consecutive times and have no temper when you hit three." At this time, a voice came.

"It's going to be a midterm exam. Don't hurry up and review, be careful that your grades will drop to 200th place." Liu Yichen didn't even raise his head. He continued to write the 'b' on a multiple-choice question and analyzed it slightly. After writing the 'b' in order on the draft paper.

"For this, this is the wrist and ankle that I give to you specifically. Take it with you during the competition, be careful of being hurt." Feng Lin said, holding his wrist and ankle and put it in front of Liu Yichen.

"You little rich woman, really don't lack money, but since you gave me a gift, I have to reluctantly accept it." Liu Yichen paused for a moment: "Wait until mid-next month, I'll treat you to KFC."

Liu Yichen did not refuse and put away the gift.

"Liu Yichen, do you play basketball so well? Do you really don't consider being a professional basketball player? I heard that professional basketball players now have a high income and a high social status." Feng Lin lowered his voice.

In libraries, loud noises are prohibited and quiet should be kept.

"I don't want to be a professional basketball player!" Liu Yichen said calmly: "No matter how high the social status is, there are also high university professors? I have said that my goal is to be a top student! A top student is my way back."

"Okay, Liu Xueba!" Feng Lin teased Liu Yichen, then took out a green exercise book from his bag and found a question: "Look at this question, will it be possible?"

"Have you finished all the compulsory 3?" Liu Yichen looked at Feng Lin. This question was the common finale of compulsory 3 in high school mathematics.

"It's almost done. You can finish teaching in the whole week next week. You will have to take 4 after the exam!" Feng Lin said.

Well, this teaching speed is really fast enough!

"This question is very simple, a typical question that combines sets, graphs and probability. In this question, you actually convert the inequality of two sets into a rectangle. The rectangle is divided into two halves by a straight line. The geometry above the line is the shadow area, and the probability is the s shadow/s rectangle..." Liu Yichen wrote directly: "So probability p=s shadow/s rectangle=3/10=0.3 or 30%"

"You see, if you just look at the question, it is difficult to figure it out. This kind of question is to convert known conditions into a graph, that is, xy coordinate diagram, and draw two geometric shapes represented by geometry. This is very phenomenon, and it is much easier to solve." Liu Yichen said.

"I understand." Feng Lin suddenly realized.

The focus of the 3 compulsory high school mathematics compulsory is statistics and probability. Although there are not many pages in the textbook, there are many contents that can be tested. The most common ones are dice, geometric figures, collections, or sports competitions, etc. There are many variations. At this time, you have to understand the knowledge points to deal with it easily. Rotary memorization is useless.

Seeing Feng Lin understand, Liu Yichen felt that Feng Lin could still save her, unlike her sister who is already in a rescued category in mathematics.

"Then is the same as this question..." Feng Lin drew x and y weeks on another question, then drew the graph of the given inequality and found the answer.

"Well, that's right. Don't panic when encountering such questions, keep calm!" Liu Yichen said: "In fact, math questions are not good, but are done well, understand their test points, and master the knowledge points. As long as you master the knowledge points, even if the test questions change, you can still respond to changes with the same change."

"For example, for example, a random ball-taking question like this, we first look at the question, list all possible results to form basic events, see how many events there are in total, and then the sum of the numbers is greater than the requirements of the question, so that the answer can be found." Liu Yichen said: "For this type of ball probability, you don't need to answer the question in a hurry first, but review the question, and then don't be afraid of trouble. List the total number of basic events formed one by one and solve it according to the problem."

Liu Yichen has already mastered this type of question type very deeply. After all, Huanggang secret scripts are not vague, and he has already understood the mastery of knowledge points.

"So that's it..." Feng Lin seemed to be enlightened: "Thank you, Liu Yichen...mua!"

Liu Yichen was stunned!

After a long time, Liu Yichen reacted, and Feng Lin had already left.

"Damn~~~Feng Lin, what do you mean? Sneak kiss me~~~"

Liu Yichen touched the cheek of the kiss, and wanted to go to Feng Lin to make a good argument. Why did he secretly kiss me and attack me?

It's so annoying!

After shook his head, Liu Yichen drew a portrait of a girl in the notebook, which looked a bit like Feng Lin. Liu Yichen spent another knife, a sword, and there was blood dripping on the sword. He fantasized about removing Feng Lin from a large amount of money.

After making a good temper, Liu Yichen calmed down and continued the questions he had not done well.

On the other side, outside the library, Feng Lin felt that her whole body was hot. She felt that her face was about to have a fever, and her heart was beating quickly, and she was both panic, proud and sweet.

"You're going to die, Feng Lin, you're so shameless. You actually took the initiative to kiss a boy. Are you shy? ~"

"Hehe~~ I have a sudden attack, his first kiss is mine~~ Those fox girls still want to make friends with Liu Yichen and dream."

"The world is full of thousands, and I love three times. The sun is the moon and you. The sun is the morning, the moon is the evening, and you are the morning and evening... What Liu Yichen likes in his heart is me... I also... like it."

Feng Lin returned to the dormitory with a blushing face and hid in the bed.

"Liu Yichen, if you like other girls, I will... click you!" Feng Lin hugged the big bear on the bed, twisted his hand on it, revealing the fierce side he thought was.

"But... he studied so well... If my studies were too different from him, wouldn't he be worthy of him?" Feng Lin suddenly thought of a question, that is, although his grades were pretty good, it seemed that Liu Yichen was much worse.

"Feng Lin...you have to work hard, work hard..." Feng Lin secretly cheered herself up. Thinking of so many girls cheering for Liu Yichen on the basketball court, Feng Lin felt a sense of crisis in her heart.

There is a very important reason why she is so bold today. Feng Lin felt a sense of crisis. After all, there are several girls who cheer for Liu Yichen, who are not worse than her.

In case...in case...

Liu Yichen was led by the bad boys in the school team and wanted to have a girlfriend. Wouldn't that be awful? But she knew that everybody on the school team had a girlfriend.

Even... it is said that there are several high school boys living outside the school with their girlfriends, which is already an open secret at No. 1 Middle School.
