Dead!

The audience was silent!!

All the students didn't expect that Wu An would really say all the answers to the multiple-choice questions!

moreover

All right!

A good question!!

If not, Lu Yunxi would never be able to cheat!

Everyone will think that the two of them have colluded in advance!

Yang Yan's face was pale!

He could never have imagined that the result would be so unbelievable!

Cai Wenqi looked confused!

She considers herself a top student!

As the class president of class 11, his academic performance has never fallen out of the top three in the class!

But even if it is her, when she makes a Huanggang test paper, it takes a lot of time!

In the end, it is not always possible to pass!

But what about Wu An?

In less than a minute, it's all done!

It's just a multiple-choice question though!

But the 100% accuracy rate makes Cai Wenqi feel incredible!

This Wu An...

Is it still human?

How could he casually make all the multiple-choice questions?

And, or is it all right?

Is this still the Wu An she knew before?

Cai Wenqi only felt dizzy!

Compared with Yang Yan and Cai Wenqi's disbelief,

Standing on the podium, Lu Yunxi, who planned to make things difficult for Wu An, can be said to be shocked!

"Wu An, this... Did you figure it out yourself? ”

Lu Yunxi settled down!

She suppressed the shock in her heart and asked tentatively.

"Or else? Do you think I'm guessing? ”

Wu An's expression was calm and he smiled indifferently!

Hiss!!!

Including Lu Yunxi, everyone gasped!

Guess?

Multiple choice questions are not proof questions, even if you really can't, just choose randomly, it is still possible to answer correctly!

After all, with just four options, even if you rely entirely on luck, you can get a few questions right!

But!

It's normal for you to get one question right, you can accept three questions, and you're lucky to be right for five questions!

But you got all of your 20 multiple-choice questions right...

Is this so possible!!

It is a 1 in 4 probability that one question is right, and two consecutive questions are 1 in 16 probability...

...

Twenty times in a row, it is a 1 in 1099511627776 probability!!

The probability of winning the Mark Six grand prize is not so small!

However, there are still some students who insist on other views!

"Teacher, Wu An must have done this set of test papers in advance, and memorized the answers to the multiple-choice questions!"

Yang Yan got up abruptly and shouted loudly!

As soon as these words came out, all the students were suddenly surprised!

Also right!!

With Wu An's results, this is also the most reasonable explanation!

Although the Huanggang test paper is known for its difficulty, the degree of confidentiality is not very high!

Even, on the Internet, you can buy a lot of such test papers for a few dozen dollars!

Wu An was lucky, and he happened to do the test paper given by Lu Yunxi!

Also, write down the answers to the multiple-choice questions!

Thinking of this, everyone's gaze at Wu An was filled with deep contempt and contempt!

It seems that Wu An is saddled with a clown who deceives the world and steals his name, and in front of everyone, he is just grandstanding!

"Yes, Mr. Lu, it must be so!"

Another student immediately echoed, looking at Wu An, his eyes were full of joy and sarcasm!

"Wu An, have you done this set of test papers before?"

Lu Yunxi also spoke, staring at Wu An with beautiful eyes, with a hint of scrutiny!

If Wu An really did this set of test papers, but hid it from everyone, she would be relieved!

Otherwise, Wu An will really be too demonic!

Even with her knowledge, those real top geniuses in the world may not be able to do Wu An's way, just glance at it and pick out all the multiple-choice answers!

"Hehe..."

Wu An chuckled lightly and said lightly: "I said that it was done, it must have been done on the spot!" ”

"Talk about it, who wouldn't!" Yang Yan stared at Wu An directly, full of ridicule: "If you have the ability, you go up and write out all the steps of the fill-in-the-blank proof question!" ”

"That's fine!"

In the stunned eyes of everyone, Wu An casually agreed.

At this time, his brain domain development degree is more than 10%!

Any question, just look at it and you will know the answer!

As for the problem-solving process, it is naturally not a problem!

forthwith

Wu An got up directly, picked up a piece of chalk, and walked to the blackboard!

Yang Yan was stunned on the spot, and a bad feeling was born in his heart!

This Wu An agreed so happily, could it be that he really had confidence!

But how is that possible!!

Multiple choice questions, even if you can't, but as long as you read the answers, it's a little impression after all,

If you have the heart, you can still memorize it!

Fill-in-the-blank questions and proof questions, especially those of this difficulty in the Huanggang test paper, involve various formulas and concepts, and you can't memorize them at all!

To understand is to understand, not to understand is not to understand!!

It's just that while he was thinking, Wu An had already begun to write!

I saw him writing on the blackboard wantonly, and many theories came to him, just like those scientists in history, and a random conclusion written out was enough to solve the problems of the ages!

"Known A=1-1\/2+1\/3-1\/4+...+1\/99-1\/100..."

“B=1-1\/2+1\/3-1\/4+...+1\/99-1\/100=1+1\/2+1\/3+......+1\/100-2(1\/2+1\/4+1\/6+....+1\/100)！”

...

Dadada!!

One topic after another was calculated in Wu An's hands, and he wrote it quickly, without the slightest hesitation and pause, but it was extremely neat!

It seems that it has been calculated thousands of times in my heart!

Yang Yan was originally full of confidence, looking at the blackboard casually!

But as Wu An continued to write, his eyes widened wider and wider, full of incredible!!

Although he didn't look at the questions in the test papers, Wu An's solution was reasonable, logical, and without a trace of omission!

What's even more terrifying is that many of the problem-solving ideas are amazing!

If you hadn't read what Wu An wrote and given him a hundred years, you wouldn't have thought of it!!

Ten minutes later...

Yang Yan's eyes were glazed, and he looked at the number formulas on the blackboard in a daze!

Immediately after, he seemed to think of something, and looked at Lu Yunxi hopefully: "Teacher, what is this?" ”

The other students also looked at Lu Yunxi in unison!

They know that only Lu Yunxi knows whether what is written on the blackboard is right or wrong!

But after reading it, they found that Lu Yunxi's pretty face was as white as paper than them!

Suddenly, everyone understood!

Peat!!

You've really made it all!!

Everyone was stunned, as if they had seen a ghost!

"Teacher, can I go down!"

At this moment, Wu An's voice sounded faintly, waking Lu Yunxi up.

"Of course... Of course you can go down! ”

Lu Yunxi was also confused!

She took a deep breath and looked at Wu An's gaze, which was full of complexity!

It seems that the other party is really a genius!

A top genius who has been buried!!

Thinking of this, her eyes changed, full of heat!

Who doesn't want their students to be geniuses!

It's just that, next, Wu An frowned, glanced at Lu Yunxi up and down, and said:

"Teacher, there is a sentence that I don't know whether to say or not!!"

Lu Yunxi's pretty face was full of smiles, and the more she looked at Wu An, the more she liked it: "You say, in front of the teacher, you don't have to be restrained, you can say whatever you want!" ”

In the surprised eyes of everyone, Wu An said in a solemn tone:

"Teacher, you're sick!"
