Chapter 23 Yes, it’s nine rabbits!

"Fuck, Qiao Yu, wake up, wake up quickly!"
After early self-study get out of class, Zhou Shuang went out to use the bathroom. After walking around in the corridor, he ran back to the classroom excitedly, and then began to slap his deskmate hard.
Qiao Yu opened his eyes sleepily, glanced at Zhou Shuang who looked excited, and asked angrily: "What are you doing?!"
"Fuck, fuck, fuck! How could you still sleep? You don't know that the guy named Xu in class last night dared to confess to your girl in public. But you are lucky, that guy was directly rejected by your wife in front of everyone. "It's so shameless." Zhou said with beaming eyebrows.
My brain, which had been forced to turn on, still felt groggy.
But the words "your wife" in Zhou Shuang's words suddenly made him sober...
Are you kidding? Wife? This word can also be used randomly?
Surprised, he asked: "What wife?"
"Xia Keke! Stop pretending. Who in the whole grade doesn't know that you two are a couple? It is said that Xia Keke rejected the man named Xu yesterday because of you. Although it sounds very cool, I still feel We old men cannot tolerate this!
I know that she is your wife, but I still dare to confess my love in public. I don't take you seriously! Qiao Yu, don't worry, as long as you say something, the brothers will help you stand up for you tonight and show some color to that surnamed Xu. , let him know what Class 13 cannot be humiliated!"
Qiao Yu was speechless.
Not only did he not feel angry, he even felt a little pity for the man named Xu.
He is just a poor child who was deceived by Xia Keke’s innocent beauty, so what does he always say? Appearance is a no-no. When choosing a girlfriend, you must not just look at appearance, inner beauty is also very important...
For example, if it were him - well, Qiao Yu felt that he should probably choose a beautiful one first.
Thinking about it this way, Xia Keke seems to be pretty good indeed. Apart from being a little more mischievous and having a tendency to take care of others when nothing happens, there is nothing wrong with her.
Wait, we had breakfast together this morning and went to school. I didn't hear Xiao Nizi mention this matter at all. It seems that she really didn't take that person named Xu to heart.
That guy is even more pitiful...
Thinking of all this nonsense in my mind, I asked calmly: "How do you know?"
"I've confessed my feelings publicly, how can I still not know? The whole grade has almost spread the news. I heard from the Rocket Class that as soon as the person named Xu arrived in the class, their class teacher called him in for a talk. They talked for a whole time. I studied by myself early, and I haven’t gone back to the classroom yet!”
After saying that, Zhou Shuang grinned and sneered: "You deserve it!"
The expression on his face was just short of gloating over misfortune, which showed that he really shared the same hatred as Qiao Yu.
"He's in such a miserable state, why do you still want to show him some color at night? It's a bit humane, right?" Qiao Yu said angrily. After trying to continue sleeping on his stomach, he found that he couldn't sleep at all. In the bottom of his heart, He sighed and picked up the chemistry book.
It can only be said that his classmates are really too idle and have no pressure to survive. Their little minds like to think about things that are not there. If they eat twice a day, they will definitely have no time to think about love.
In addition, he has already arranged all the tasks for the recent period.
During the day, I review my junior high school knowledge and prepare for the next mock test and the final high school entrance examination. I go to Teacher Lan's competition class on one day to take care of errands and learn professional mathematical layout software applications. I use my evenings and weekends to prepare. Next up is the Little Libaba Global Mathematics Competition.
As for love...
Qiao Yu felt that love was a very heavy thing for him and Xiao Nizi at this time. After all, he didn’t have a father in his life. The young man just didn’t have the experience of being a father. He didn’t even have the experience of being a son to his father. None.
So his first task now is to make money, and love can indeed wait until college.
"No, I'm not thinking about you! I have to make that Xu know his status... Hey, why do I feel so heavy when I see you flipping through the book now? Well, Qiao Yu, why don't you help me Let me test, do I have any talent in mathematics?"
Qiao Yu glanced at this guy searchingly.
"I went to an Internet cafe last night to look at the online English courses. I found them very difficult. I feel like I may not have any language talent. But I thought you were quite handsome when you did math problems yesterday. When Lao Gong saw your expression, it was amazing! So! I just thought, how about I try to learn mathematics?" Zhou Shuang explained.
Qiao Yu withdrew his gaze, returned his attention to the chemistry book, and said without raising his head: "This is simple, suppose there is a closed ecological experimental area, and the staff put three rabbits into it every day for three consecutive days. , so how many rabbits are there in this ecological experimental area on the third day?"
"Fuck, you're looking down on me, aren't there only nine?" Zhou Shuang replied angrily.
The deskmate thought this was a real IQ humiliation, but Qiao Yu obviously didn't think so, and said seriously: "Look, you have a very good talent in mathematics. Believe me, mathematics is actually just such a thing."
Zhou Shuang was speechless and said dullly: "Qiao Yu, we can be considered friends after all. How can you deceive your friends like this?"
Qiao Yu sighed and finally looked away from the chemistry book. He looked at the dejected look of his deskmate, thought for a while, then picked up a pen and paper and started writing, mumbling something.
"Okay, it's still a closed ecological experimental area. There are a group of rabbits in it. After observation by the staff, it was found that the change in the number of rabbits A with time t can be described by a differential equation: dA(t)/dt=A(t )*(a-bA(t))
Among them, a and b are constants, representing the natural growth rate and environmental inhibitory factor of rabbits respectively. At the same time, the researchers also found that when t=0, the number of rabbits in the experimental area was 4. Assume that after ten days of observation, the number of rabbits We have reached nine. What is the maximum number of rabbits that can be accommodated in the environment of the experimental area?"
After writing, Qiao Yu directly handed the manuscript paper to his deskmate, and then said encouragingly: "Believe in your mathematical ability and intuition. Come and tell me what the answer to this question is!"
Zhou Shuang looked at the question blankly, and then answered uncertainly: "Just nine?"
"Holy shit, you got the answer right! Classmate Zhou Shuang, you are such a genius, you already know how to push to the limit!" Qiao Yu raised his hand and patted Zhou Shuang on the shoulder, then picked up the chemistry book again.
Qiao Yu felt that he had done all his kindness and justice. He couldn't say that you were hopeless, stop struggling and give up, right?
After all, he is a deskmate and a good friend, so it is good to encourage him to learn more.
Fortunately, Zhou Shuang is not really stupid.
He glanced at the scrawled handwriting on the paper again, especially the formula that he couldn't quite understand, and suddenly realized that there was a huge gap between him and his deskmate who he thought was a fellow student. It is 8848 meters long.
After thinking about it, I suddenly cried out in my heart: "Qiao Yu."
"Um?"
"Sign your name under this question."
Qiao Yu turned his head and looked at his deskmate suspiciously. This request was not normal.
Zhou Shuang said seriously: "I plan to keep this question."
Qiao Yu was speechless, then picked up the pen.
Chapter completed!
