Chapter 12 Calculator for $400

After the second class in the afternoon, Chen Fang walked into the classroom, which instantly restored quiet to the classroom that was a little noisy at first.

"I would like to emphasize to you again that National Day only means that the college entrance examination is closer to you. Do it well when you go home. This is for you, not for me! It is better not to copy other people's papers. Do you hear me? !”

"I heard it!" the classmate below responded immediately.

"I hope you can really do it." Chen Fang nodded with satisfaction, "One more thing. After the National Day, there will be an exam the following month. The exam content basically covers all the knowledge points in the entire high school, and the results will be ranked by grade. , it’s very important, give me a good test.”

"ah……"

After hearing Chen Fang's words, people were filled with grief. The bad students simply hated exams, while the top students were afraid that their ranking would not be good enough for the exam, which would affect their self-confidence.

"Ah, what? I'm in my senior year of high school and I'm still afraid of exams. I still have the strength. Why don't you study hard these two days? Otherwise, if you fail, don't say I didn't warn you."

After talking a lot about the test center and the recent performance of his classmates, Chen Fang finally announced the end of school.

"Hey, top student, did you hear that the monthly exam is about to take place? Do you want to prove yourself?" After putting on his schoolbag, Gu Fan nudged Wu Bin twice with his elbow and said, of course, his tone was mocking.

"What's the point of proving? There's no pleasure in winning against a scumbag like you." Wu Bin expressed disdain.

"Tch, of course there's no point in competing with me. You've been studying hard for a month, and you still have to be in the top 50 in your grade."

Xu Hao, who came over at this time, also heard Gu Fan's words and laughed loudly: "Awesome, Wu Xueba is about to reach the top 50 in his grade?"

"Top 50 in what grade?" Wang Qi, a tall man, also gathered around.

When Wu Bin turned from a teenager in an Internet cafe to a top student in answering questions, students like Xu Hao and others not only did not alienate him, but paid more and more attention to him, paying attention to what he was doing in class, what he was doing after class, and what he was doing during lunch break.

As for why you are so concerned? Maybe they wanted to see Wu Bin fail in the exam after working hard and return to their team. Maybe they wanted to see him really succeed in counterattacking and send his blessings. But they actually know which side has more ideas.

"Won't you know after the exam?" After Wu Bin said this, he put on his schoolbag, picked up his English book and walked out the door.

After hearing this, the three of them chased after them and started yelling again, expressing their "care" for their friends with venomous tongues.

"Wu Bin, come here."

As soon as he left the classroom door, Liu Yushan appeared in front of several people.

Looking at this familiar scene, Gu Fan and the others thought that they were adding more ingredients to Wu Bin?

"Do you still have any papers for me? Teacher Liu?" Wu Bin quickly walked up to Liu Yushan and asked with bright eyes.

"That's enough for you at noon. I'm here to ask if you have a scientific calculator?"

When he heard that it was not a paper, Wu Bin was a little disappointed, nodded and said, "Yes."

"Have you brought it?" Liu Yushan asked again.

"Oh, let's put it in the dormitory."

Scientific calculators are useful for calculating problems for top academics, but for low-achieving students, they can be used to calculate 1+1. Oh, you can also use it if you are a technical calculator with a talent for black technology. The function of generating random numbers to play Three Kingdoms.

"What brand is it?"

"It seems... Dahua?" Wu Bin's scientific calculator was a knock-off that he bought in the first year of high school. It cost 80 yuan, and it was purely for teachers.

"Then it would be better for you to change to another one. Come to the office with me and I will show you the calculator I recommend."

"Oh, okay." Wu Bin nodded, then turned back to Gu Fan and the others and said, "You go back first, see you at the beginning of school."

Watching Wu Bin leave, Gu Fan and others felt a little complicated, but in the end they decided to go to the Internet cafe to have sex.

When he came to the office, Liu Yushan took out a silver calculator from his desk drawer and introduced to Wu Bin: "This is Casio's calculator, the model designated for the college entrance examination. I will teach you some functional operations later." You need it, so I recommend you buy one, it’s very useful.”

"Yes, you should buy one. This calculator is also very useful for calculating electricity, especially when participating in competitions. An equation can easily be multiplied by several roots and several powers." At this time, he was packing his things. Cai Guoping also said something.

"Hey, Teacher Cai is ready to let Wu Bin participate in the competition." At this time, the biology teacher Jiang Lan joked.

This month, Wu Bin ran to the office all day, so several teachers in the office became familiar with him and liked to tease him when they had nothing to do.

"Hey, Teacher Jiang, please don't tell me. This kid might really be a promising young man, but he just started too late." After Cai Guoping finished speaking, he glared at Wu Bin, as if he hated iron.

Looking at the calculator in front of him that was ambushed by two teachers, Wu Bin nodded and said, "Then I'll buy one when I get back."

"Well, the stationery store next door sells it. If you buy it, I'll teach you how to use it after the holiday." Liu Yushan nodded towards Wu Bin.

After meeting several teachers again, Wu Bin, who left school, first went to the stationery store across the street from their school to find the boss and asked, "Boss, do you have a Casio fx991ES calculator here?"

"Yes, this is it, right." The boss skillfully took a box from the shelf and placed it in front of Wu Bin.

"Yes, that's it." After confirming that the model number was correct, Wu Bin asked again: "How much does it cost?"

"384."

Wow...it's so expensive.

Wu Bin, who didn't even have a red ticket in his pocket, suddenly felt a pain in his balls and had to say: "Okay, I'll buy it later."

Wu Bin's mother never felt bad about buying school supplies. Without saying anything, she took out four red bills and gave them to Wu Bin who came home and said she wanted to buy a calculator.

After buying the calculator, Wu Bin read the manual and tried a few equation calculations, complex number calculations and vector calculations according to the methods mentioned above. He found that it was indeed very useful, but he still couldn't tell that it was much more expensive than other calculators. Where are the hundreds of places?

After his curiosity about the new toy disappeared, Wu Bin immediately took out a pile of papers from his schoolbag and randomly picked a mathematics paper from it to start working on it.

At around six o'clock in the evening, Wu Bin's mother walked into Wu Bin's room and shouted: "It's time to eat."

"Oh, you guys eat first, I'll be here after I finish this paper." Wu Bin replied without raising his head.

"It's okay to study after eating. I cooked your favorite short rib soup today. It won't taste good when it gets cold."

Wu Bin's mother not only has no doubts about Wu Bin's current motivation to study, but is even a little worried about whether this motivation is too strong. Don't learn stupidly, so sometimes she even drags Wu Bin to the living room to watch TV for a while to let him relax. Relax, but if she doesn't pay attention, she will find that Wu Bin has slipped back into the room to do the questions again, which makes her really happy and worried.
