How to break into a math book

A familiar feeling came over me.

Holographic online game!

Su Gechi actually turned the mathematics teaching aid into a holographic game, which is really big enough.

Tu Hua calmed down instantly, he is not good at mathematics, but games...he is an elite.He slid his hands in the air, and a projection screen appeared, with his name and gender written on the upper right corner of the screen, followed by a line of divisions, painted in the tenth district.

On the right is the current state property of Tuhua:

【Current Level: None】

[Main quest: None]

[Sub-quests: None]

【Props: None】

In the center of the screen is written a line of big characters:

[The number of online users is 200000, and the primary election will be automatically opened after 04:55]

20 people, ten districts, equivalent to 2 people in one district.Tu Hua looked around the huge campus, it looked like a school, but the students were not in the classroom, some were walking on the track, some were sitting on the lawn, gathered together in small groups, Seems to be plotting something.

These students should be the same challengers as Tu Hua.There are also numbers on the back of their school uniforms, some are "2", some are "5", and some are "1" like Tuhua.After observing for a while, he did not find a number greater than 9, that is to say, these challengers, like him, chose any one of the ten natural numbers 0~9 when they entered the school, and he came because he came too It was too late, and there was only one number "1" left, so I had no choice.The meaning of these numbers is still unknown, but Tu Hua thinks it may have something to do with the grouping attribute.

There is no other useful information on the system screen, but Ke Tuhua discovered the most fatal point: there is no exit option in the system.

In other words, in this virtual environment, which seems to be the same as online games, the challenger cannot exit voluntarily.Tuhua has been playing games for so many years, but he has never encountered such a situation.

Forced to play?

"Ding--"

Soon the 5-minute countdown ended, and after the beep sounded, the system screen popped up again, and the light blue fonts began to flash in the air:

[The primary round is about to open, challengers who pass the level within 48 hours can enter the next level, and the rest of the challengers will be eliminated.I wish you all a happy game in the world of mathematics. 】

[Challenge content of the primary level: x2-3x+2 solution. 】

The flickering of the system screen stopped, and a 48-hour countdown began to appear in the center of the screen.

The campus immediately became restless, and most of the challengers, like Tu Hua, were scratching their heads at this question.If you add an equal to 0 to the back of this formula, Tuhua can see the answer at a glance, two solutions, 1 and 2; or add a dependent variable y to the front, which is a quadratic function with an upward opening of the image.

But this question is clearly incomplete.

Tu Hua tried to click the [Answer] button on the answering interface, and soon the system popped up a prompt box: [The conditions are not complete. 】

So this is not a wrong question, the real purpose of this level is to let the challenger find the conditions that can make the equation true.If a question with complete conditions is given so easily, the difficulty will be too low.

Tu Hua put away the system interface, and strolled along the playground with arms folded. The conditional clue must be in this school.

Most of the challengers have already figured out the ins and outs, and started to look for clues. Some went to the classroom, and some went to the library and gymnasium. Most of them have formed their own teams, and only a very few of them wandered alone like Tu Hua.

While walking towards the classroom, Tu Hua wondered if he should also find a teammate, but bumped into someone on the steps at the entrance of the teaching building.

Subconsciously wanted to apologize, turned around and saw the face of the person hit: "Wang Boyu?!"

"Tuhua!" Wang Boyu has a prickly hair, black and bright eyes, "You are also here to participate in the math challenge?!"

He and Wang Boyu were in the same school when they were in junior high school, and they were neighbors, so they have a close relationship.However, after the senior high school entrance examination, Tu Hua entered the key city, and Wang Boyu only went to a general high school. In addition, Tu Hua moved, and the contact between the two became less and less.

Both of them were very excited to meet a good friend from the past here.

Wang Boyu patted Tu Hua's shoulder with a smile: "Being able to participate in this challenge, does it mean that your math score has improved?"

Tu Hua curled his lips in embarrassment: "As always."

Wang Boyu said: "Then why can't you figure it out and come to the math test? I heard that these test questions are very abnormal."

"I thought it was just an ordinary tutorial book. Who knew it would be sucked in just after I wrote two words." Tu Hua was also helpless.

"It seems that you really don't know anything!" Wang Boyu embraced his shoulders and said, "This "Mathematics Breakthrough" is limited to 20 copies nationwide. It is not an ordinary teaching aid, but a game that integrates mathematics. The virtual experience world in the book! This book is hard to buy, and my parents bought it for me through their relationship!"

"The most important thing is that Professor Su, who edited this book, has successfully applied to the Ministry of Education, and he can choose one of the students who passed the customs to be admitted to University A!"

Tu Hua's eyes lit up instantly.

The condition of being recommended to A University is too tempting, no wonder so many people flock to it!Such a good opportunity to be at the same table was given to him. Thinking about it, I knew that this deskmate who was still copying homework for a living in the third year of high school obviously didn't have this ambition.

Instead, he hit Tu Hua in the wrong direction.With Tu Hua's math grades, it is impossible to get into A University.Although this level-breaking game is highly competitive, it is also an opportunity.

Tu Hua regained his energy immediately, and immediately threw himself into it: "Have you checked over there in the classroom?"

"Ah?" Wang Boyu, who was still emphasizing the background of the game, was a little confused by Tuhua's sudden change, "There are a lot of people, so I didn't look carefully..."

"Let's go." Tu Hua dragged Wang Boyu and walked towards the corridor. Sure enough, the corridor was full of people, and the corridor, which was not very spacious, looked very crowded.Everyone stretched their necks and looked into the classroom, but the doors of all the classrooms were locked, and the windows of the classrooms were also pitch black, and nothing could be seen.

Tu Hua grabbed a girl casually and asked, "What's going on?"

The girl turned her head impatiently, she didn't expect it to be a handsome guy, and her attitude softened: "These classrooms are very strange, and the people who go in never come out again, so many people are waiting and watching, waiting for the people inside to come out to see what it is Condition."

Tu Hua thanked, and squeezed through the crowd with Wang Boyu.This teaching building has 6 floors, and each floor has 12 classrooms, that is to say, there are 72 classrooms in the whole building.

No one knows what is in these classrooms. It is indeed a very dangerous behavior to rush into unknown territory. Tu Hua chose to wait and see like most people.Any game can only be played if the rules are clear.From the moment he entered the world of "Mathematics Breakthrough", there was no guidance such as a novice tutorial, and everything was unknown.

But the premise is that someone in the classroom comes out.

More than 20 minutes have passed, and no one has come out.Tu Hua and Wang Boyu leaned on the railing of the corridor, observing the twelve classrooms.Wang Boyu was obviously anxious, and he dragged Tu Hua to the nearest classroom: "What's the situation? No one has come out for so long? Shall we go and have a look?"

"You can't see it from the windows unless you actually go in."

When Tu Hua explained, Wang Boyu had already put his hand on the doorknob, and turned it slightly to the right: "I can't see the window, so just open the door a little!"

Tu Hua hurriedly pressed his hand: "We don't know what the system's criteria are for judging you entering the classroom. Maybe it's walking in, or maybe it's just the action of opening the door?"

Wang Boyu wanted to withdraw his hand, but at the next moment, a fat man in the crowd behind him accidentally bumped into him. Wang Boyu staggered, and the door "squeaked" while he was holding on to the handle. Before he had time to see the classroom clearly At the time of the situation, another hand that wanted to stabilize the body had already patted on Tu Hua's back.

Accidentally pushed him into the classroom.

Tu Hua entered the classroom in such a state of bewilderment. When he wanted to turn around, he realized that the bustling crowd at the door just now had disappeared. Although the door of the classroom was open, he couldn't get out.

Like the gate of the school, there is an invisible barrier blocking him.

It seems that he has entered another dimension.Tu Hua thought helplessly, this guy Wang Boyu really is a trap.

"Tu Hua, you're finally here." A gentle male voice came from behind, and Tu Hua turned his head to see the situation in the classroom clearly.

The one who called him just now should be the young teacher on the podium, but there are only four desks under the podium, and the three on the left have already been seated. Two boys and one girl should be challengers.

So this last empty seat...was his?

"I agreed to take a quiz today, Tu Hua, why did you forget?" Seeing that Tu Hua was still in a daze, the teacher urged, "Go back to your seat and sit down."

This teacher looks to be only in his 20s, wearing a camel V-neck sweater, he is tall, the table top of the podium only reaches his waist, he is very handsome, unexpectedly the NPC in this math breakout game is quite beautiful .

Unable to figure out the situation and unable to leave the classroom, Tu Hua had no choice but to resign himself to his fate and walk to his seat.There is only a piece of white paper and a pen on the desk, nothing else.

Tu Hua was about to ask the person next to him what was going on, only to realize that he knew the girl sitting next to him.

Sun Wei.

He is in the same high school as him, and has been the invincible top student in his grade all year round.However, this girl did not get along with Tu Hua, and it was caused by an embarrassing confession incident.

Sun Wei confessed his love to Tu Hua when he was a sophomore in high school.She has excellent academic performance and looks not bad, just like her confidence in her grades, she is confident that Tu Hua will like her.

Ke Tuhua refused.And the reason for the refusal was quite perfunctory: "I'm sorry, I'm gay."

Sun Wei, who had always been proud, left crying. From then on, he never looked sideways at Tu Hua, didn't say a word, and became colder than before.

At that time, the boys in the class said that it was a bit too much, even if they didn't like other girls, they had to be more tactful. The excuse of pretending to be gay was too low-level.But only Tu Hua knew that he was telling the truth.

He knew from the beginning of puberty that he didn't like girls.He is handsome and has never had a girlfriend. Everyone thinks that he concentrates on his studies and is alone. In fact, he is very bitter: Not only do I not have a girlfriend, I have never even had a boyfriend.

A poor, loveless single dog.

Sure enough, Sun Wei didn't even give him an out of the corner of his eye, and stared at the teacher on the podium with a straight face.

"Now that we're all here, let's start the quiz!"

The system screen jumped out immediately:

[Sub-quest: 24-point game]

[Rules: A total of three rounds of 24-point games are played, and an elimination mechanism is implemented. Challengers who answer incorrectly can choose to accept punishment or be eliminated. Challengers who choose to be punished will enter the next round of the game after punishment; challengers who choose to be eliminated will be forced to quit "Mathematics Breakthrough", the third round of correct answerers pass the level. 】

The moment the system screen disappeared, four numbers slowly appeared on the white paper on the desktop.

【5,5,5,1】

The author has something to say: For those who don’t know the 24-point game, here’s an explanation: It’s a mathematical game that uses addition, subtraction, multiplication, division, and parenthesis operations to make 4 integers (usually positive integers) so that the final calculation result is 24.Will it count if I try it~

PS: Gong has appeared

**The small 2 in the upper right corner of x square is not displayed, I will mark it with text directly in the future~
