Jiangcheng No. 3 Middle School Senior 3 (2) class

There are 101 days left until the college entrance examination

"Students, it's class time—"

The familiar class bell rang, Fang Yang opened his eyes, and began to self-discipline again

) of the day

"Teacher Wang, all the homework in the class has been handed in except for Fang Yang!"

[The host of the tile area can't stand the rotten behavior of this system, the strongest learning system is on, don't put it bad]

Fang Yang squinted, recalling the voice that had just appeared, what was this? System? It seems that I have stayed up too late lately and hallucinated

We are preparing to continue to regain our strength

), a loud roar gave Fang Yang a stirring spirit

On the podium, the battle-hardened homeroom teacher and math teacher above his head looked at Fang Yang with a gloomy face.

Zhang Zhonglin, the head teacher, was affectionately called "Brother Guan" by his classmates because he brought out the champion of the city competition

"Fang Yang, you stood up for me, did you do your homework?"

[I have to show you the power of this system, congratulations to the host for obtaining the "Brain Upgrade"]

？

That's not right, right

What's the sound? Could it be!

Fang Yang looked at the gloating front table and the people around him, and he could basically be sure that it wasn't one of them who said it

Is this really a system that shines into reality, and from then on, can you go to the pinnacle of life and get ten consecutive draws...

Fang Yang, who was still indulging in fantasies, didn't notice that Brother Guan's face was a shade darker again

"Fang Yang, you can't hear me, can you?"

Only then did Fang Yang come back to his senses from the demonic advertisement and stood up slowly

is 1.85 meters tall, handsome facial features, and there is a clear stupidity in his eyes

Brother Guan is notoriously strict in the third middle school, as a class teacher and math teacher, and is about to take the college entrance examination, Brother Guan treats students more strictly

"Fang Yang! You're the only one left in the class who hasn't handed in your homework, and you're going to take the college entrance examination soon, what will you do in the future? ”

Fang Yang pondered for a moment and then spoke: Teacher, in fact, I can't blame me for not handing in my homework, I have a reason

？ If you say it, if you can't say it, you will be sanctioned by me

Fang Yang pondered for a while and then spoke: There are more than half a paper for each homework, as well as all kinds of homework for preview review and recitation, as well as my review, it is roughly estimated that I will write 10,524 words. By pressing 0.33 words a second, I have to write for 8 hours, and I have to write my homework until 6 o'clock at 10 o'clock, so in order to ensure a good night's sleep, I should master the technique of going back in time with items and then comprehend Einstein's theory of relativity, and then get a pen that can replenish the amount of ink on itself minus the time it takes to change the refill, so that I can finish my homework on time, but if I had this technique, I would still be in high school?

Schoolmate:?????????

Zhang Zhonglin, who is confused, is a little confused, why is he a little blinded, because he is very confused now

Received 1 positive value from Brother Guan

Brother Guan's face, which was originally as black as paint, finally eased a little, looked at Fang Yang and said, "Okay, since you are so strong in arithmetic now, calculate this problem."

Brother Guan faced the blackboard, the chalk in his hand was sprinkled, and he quickly wrote a math problem like English

Brother Guan looked at Fang Yang: I can't count it, you have to hand in my homework in the future, otherwise you will stand until the college entrance examination

"Determine all functions f:R→R, where the set of real numbers of R is such that for any x,y∈R, there is always being:

f（x-f（y））=f（f（y））+xf（y）+f（x）-1“

[This can't be killed directly by staring at the method? ] Congratulations to the host for obtaining the "Complete Mastery of the Staring Method"]

At the same time, Wu Wenyu, the representative of the mathematics class, also began to try to calculate the problem, he looked at Fang Yang a little gloating, although he did it, how could this perennial bottom Fang Yang calculate?

Brother Guan looked at Fang Yang and shouted: What's the matter, won't it be counted, everyone is delayed for a minute like you, that's an hour!

Fang Yang was a little emotional, Brother Guan has been saying this for two and a half years

Random immediately came back to his senses and looked at the questions on the blackboard, fortunately, there was already a staring method that was not difficult at all, and it was solved directly in seconds

Fang Yang walked slowly to the podium and wrote down the answer, but there was no process.

Wu Wenyu laughed even more, he thought that Fang Yang had risen, did he think that this was in a novel?

Brother Guan looked at the correct answer, a little confused, why...

Brother Guan was a little excited, and asked Fang Yang: "You, what method did you use, how did you calculate it so quickly?" “

Received a 10-point positive value from Brother Guan

Fang Yang was a little happy, but his face was still calm, and he said:

Staring

？？？？？？？

What is this? Brother Guan touched his head, thinking carefully about his thirty years of teaching career, and there was no such method

The class erupted immediately after a brief silence

"Hahahahaha, staring method"

"That's right, this Fang Yang is still staring at the method, and I can't fix it for Brother Guan"

Wu Wenyu looked at his different answer from Fang Yang and was a little confused, so he miscalculated? This, that's not right, right?

Fang Yang grabbed a piece of chalk at this time, broke it in half, and began to explain on the blackboard.

Zhang Zhonglin: What are your habits? What a waste?

Fang Yang pondered slightly, and randomly woke up

That's it, I'll say how hard it is to write this chalk, it turns out that Brother Guan has used it

Pick up a new piece of chalk and... break

Brother Guan: ???

Wu Wenyu looked at Fang Yang's explanation, and then thought back to his own process, the tile area, the third step was wrong

Brother Guan said: Well, it's normal that this question can't be calculated, after all, it's an Olympiad problem, are there any students who have the right calculation?

Wu Wenyu looked at the answer on the paper, then revised it to the same answer as Fang Yang, and then raised his hand.

As a class representative, how could he not be calculated?

Well, that's very Wu Wenyu

"Ah, that's what you said you did, but it's better to hand in your homework, right?"

"Okay, Brother Guan... I'll hand it in the next day

Zhang Zhonglin: ?
