If time is spent waiting, it is incomparably long.

The human brain accelerates your senses and makes every second feel like three autumns.

The first class of high school, which spent noon time in study, seemed to have come to the first class of the afternoon in the blink of an eye.

Xu is Zhao Rongbao who walked through the back door for himself, and the first class is still a math class.

"Students, we talked about trigonometric values of special angles in the last lesson, please pick up the calculator we purchased in this class, and let us calculate the trigonometric values of some non-special angles. I promise that whoever calculates first will not have to do homework. ”

Zhao Rongbao's words ignited the classroom.

The first class in the afternoon was very sleepy, and the students' spirits were already insufficient.

There were already classmates cheering

This era is so easy to satisfy, Chen Fan can't help but recall his previous life.

In high school in his previous life, he spent it in a daze, and he also spent it in playing and messing around.

Now, with a chance to do it all over again, he plans to make up for his past regrets, which is why he can choose to continue to go to school instead of going to school.

There are some things that are more important than money.

"Boom"

Zhao Rongbao wrote a string of trigonometric functions that are difficult to calculate on the blackboard.

All the students picked up the calculators they bought that could calculate trigonometric functions and were used in high school.

Lin Miaomiao

Qian Sanyi is so

Deng Xiaoqi is so

Only Chen Fan didn't

The purpose of this lesson is to teach students how to use calculators, but Chen Fan thinks about how far he is from calculators when he now develops nine percent of his brain.

Because of this, he intends to do mental arithmetic!

It's a bold idea!

In fact, as far as possible, there is no way for humans to mentally calculate trigonometric values.

But Chen Fan said yes.

As long as you memorize the trigonometric values between 0 and 45 at any angle of sin and cos, you can do mental arithmetic.

What tan, what cot .... It's a breeze.

Of course, including the three units of the angle, degrees (°), minutes (′), and as for the smallest unit of the angle, the second ("), Chen Fan can use the ability to remember by developing 9% in his brain domain and forcibly remember it.

“0.9511”

“0.4403”

“34.7151”

Chen Fan calculated four decimal places, and he didn't know if he was right, so he could only wait for other students who used calculators.

Qian Sanyi over there didn't know that there was already someone who could calculate it mentally, but he loved to be showy in his bones, so after calculating, he immediately raised his hand:

“0.9511”

“0.4403”

“34.7151”

"It should be stable." Chen Fan smiled.

There will be no such coincidental thing in the world, it is impossible that after he made a mental arithmetic error, and Qian Sanyi also happened to miscalculate with a calculator.

And the numbers happen to be exactly the same.

There is no showmanship and showmanship

Chen Fan continued to do his own thing.

Zhao Rongbao listened to Qian Sanyi's answer, and even deliberately stepped off the podium, patted Qian Sanyi's thigh and said: "The answer is completely correct, it is worthy of Qian Sanyi." ”

Qian Sanyi's face was still cold, but the corners of his mouth rose imperceptibly, still betraying the pride in his heart, and even he looked at Chen Fan proudly.

found that Chen Fan did not participate in this event at all, his punch seemed to hit cotton, gritted his teeth, and his face was even more real indifference.

The classmates all applauded the first brother.

Jiang Tianhao also raised his hand: "Teacher, I'm the wrong one." ”

Zhao Rongbao criticized: "One mistake is also a mistake, in the world of mathematics, no mistakes are allowed, come on, continue to work hard." ”

If Qian Sanyi was born, then Jiang Tianhao was properly adopted.

Grandma doesn't hurt, uncle doesn't love.

Returning to the podium, Zhao Rongbao continued to lecture: "Students, we just told you about the basic functions of this computer today, and you can try programming to understand its true value......

The speaker has no intention, the listener has a heart, Jiang Tianhao, who was not convinced, immediately took out the manual, found the hidden code words belonging to the calculator, and even took out his mobile phone and searched the Internet.

What did you say?

Isn't your phone going to be handed in?

But Jiang Tianhao handed over a mobile phone model...

However, with Jiang Tianhao's family, it is not surprising that there are several mobile phones.

After class, I saw Jiang Tianhao holding a box of soda, walked back, and put it on the table.

It immediately attracted the attention of the surrounding classmates.

"Haozi, what are you doing here? Would you like us to drink water? Jiang Tianhao's roommate, Sun Chuanchu immediately responded.

"Open, open, but don't move yet." Jiang Tianhao commanded.

"I've developed a game, is there anything you'd like to play?" Jiang Tianhao shouted loudly.

"Haozi"

"Haozi"

"Haozi"

"Haozi"

Some of the male classmates around were instantly attracted

It's a time to learn, but it's also the time to play.

Chen Fan sat behind Jiang Tianhao, heard Jiang Tianhao say this, and glanced at the computer sign on the table.

Scales fall from one's eyes

And it's not surprising

Just because the brand is Casio

This brand of calculator first became famous because of the games it contains.

As early as 1980, Casio launched the MG-880 calculator equipped with a laser cannon to repel the invaders shooting game, and the computer quickly became popular in Fuso and neighboring countries, for which Casio successively launched a series of calculators equipped with different games, such as BB-9 and BB-10 for playing baseball games, BG-15 for boxing games, PG-200 for playing small steel balls, and so on.

as well as various games from Nintendo.

It's 2013 now

Naturally, there are some special games that you need to discover for yourself, and many people are waiting for this, and every time you discover the game one step ahead, you have an inexplicable sense of achievement.

This is also the reason why this calculator is popular.

A calculator sells for up to 2,000 yuan, can you believe it?

Many people who buy it are still happy.

The same strategy also has its watches, a model, that has been on fire for thirty-five years.

The marketing strategy is undoubtedly successful.

"What's it called, Haozi, call something I like to hear!" Jiang Tianhao shouted.

"Hao Ye, how is Hao Ye? Let us play and teach us. Sun squirmed his fat body and smiled.

"Hao Ye"

"Hao Ye"

"Hao Ye"

"Hao Ye"

"Fried golden flowers, one person and one handful, drink water if you lose! A bottle of water must be drunk. Jiang Tianhao said the rules of the game.

"I'm coming, I'm coming, I'm going to play too." Lin Miaomiao put together the excitement.

"You? If I don't play with you, are you sure you can play? "Jiang Tianhao didn't want to play with Lin Miaomiao.

"Ahem, cough, cough, I order you as a senior sister, take me one, I won't you can teach me." Lin Miaomiao began to use her identity.

"Okay, okay, press this, and that's it." Jiang Tianhao was speechless, there was no way to take Lin Miaomiao.

"Oh, it's done!" Lin Miaomiao watched the computer appear

"3 of hearts, 6 of spades, 9 of diamonds!"

"I'll come, 4 hearts, 5 squares, 6 clubs, straight, you lose, you go, no need to drink water!" Jiang Tianhao didn't want to embarrass Lin Miaomiao because of Chen Fan's relationship.

"Hey, no, why is she leaving, you kid can't be interested in seeing the color, drink water! Drink! "It's not a big deal for Sun to come out to see the excitement, with a rhythm.

"I'll drink it!" Lin Miaomiao picked up a bottle of soda and drank it.

"Huh?" Jiang Tianhao somewhat understood why Chen Fan was protecting Lin Miaomiao.

This girl is indeed different from other girls who are looking in the mirror.

"Come on, come on, I'll play with Miao Miao this time!" Sun Kuansheng knew that Lin Miaomiao didn't even know the rules of frying golden flowers, so he had other thoughts in his heart.

He wants to irrigate Lin Miaomiao!

"I'll play with you, I'm quite interested in this game!" Chen Fan put one hand on Sun Kuan's shoulder, and at the same time took the computer in Jiang Tianhao's hand.

"Smack"

The calculator "accidentally" fell to the ground and knocked out the screen.

Chen Fan picked up the calculator and pressed it a few times to restore the brightness of the screen.

"Come on, let's play, what's the point of playing with a little rookie?" Chen Fan smiled.

"Hahaha, okay, I'll come first!" Sun Kuanyu picked up the calculator and pressed "Hahaha, Q of spades, 10 of spades, 4 of spades, golden flower!" ”

"I'll go, I'll be lucky!"

“666”

"I'm coming!" Chen Fan pressed the ...... expressionlessly Two keys.

Of course no one saw it.

"I'm sorry, I won, Leopard!" Chen Fan handed it to Sun Chuan and took a look.

"I'll go, it's really a leopard, or the biggest AAA!" Sun skewed out an incredible face.

"Drink." Chen Fan laughed again!

"Okay, drink it, but do it again!" Sun Kuan was not convinced.

Gambler psychology.

Next, the two continued.

Chen Fan: "Leopard, three 2s, even the smallest, all won!" Drink"

Chen Fan: "Shun Jin (the same suit, three consecutive numbers.) I won, drink! ”

Chen Fan: "I'm sorry, I won the competition, drink it." ”

……

Chen Fan maintained his winning streak!

So much so that when the 7th bottle of water was over, Sun Kuan couldn't drink it!

The authorities are confused, and the bystanders are clear.

All the boys and a few female classmates who were watching looked at Chen Fan stupidly.

They all feel that Sun Chuan provoked an existence that should not be provoked, this is the real boss.

"Drink, a man can't say no!" Chen Fan helped Sun Kuanchu unscrew a bottle of water again.

Sun Kuan's fat face flushed and said: "Brother Fan, I was wrong, I was wrong, spare my brother's life, I really can't drink it." ”

Lin Miaomiao snatched the calculator: "Then you get out of the way, and my master and I will continue to play." ”

"I'm not playing anymore." Chen Fan warned the male classmates in the class that the purpose had been achieved, and they were ready to retire.

"Then let's do it." Lin Miaomiao said heartlessly.

"No, no, we're going to learn." The people around hurriedly waved their hands, joking, how dare they play, did they see Sun Chuan lying on the table? That's the end.

Everybody is smart

They don't want to be reckoned with and rubbed on the ground.

"Cut, it's boring, I can't play, although I'm my master apprentice, but I really can't play." Lin Miaomiao felt bored and muttered back to her seat.
