How to break into a math book

In addition to the six challengers who participated in the mission of [Mr. X's Labyrinth], some people have also completed all the main missions.Tuhua opened the system interface and found that the topic of the primary level had changed again. It was [y=x^2-3x+2] before, and now the dependent variable y has been assigned a value, which is equal to 0.

也就是说这个原本无解的式子变成了一道非常简单的一元二次方程——【x^2-3x+2=0】。涂化迅速按下解答键，在答题面板上写下这道方程的两个实数根，1和2。

【Ding--】

[The challenger, Tu Hua, has passed the primary level and is about to enter the function level. 】

After the system's announcement, Tu Hua suddenly felt the ground shake. When he raised his head again, everyone on the campus disappeared, only himself.

One after another, other challengers appeared beside him, and Tu Hua found that the way these people appeared was the same as the way they were eliminated, which was the conversion between entities and pixel particles.After a while, Wang Boyu's body was pieced together by pixel particles, as if teleported from another dimension.

Those who were gradually teleported here should all be challengers who have passed the primary level. They seem to be still in the school at the beginning, but in fact the system has divided them and the challengers who have not yet passed the level into two spaces.

The number in the area of ​​the number of checkpoints in the system is constantly rising, and it will soon rise from single digits to three digits. After 48 hours, the number should stop beating.

Paintable still feels that the number of people entering the level doesn't look quite right.At the beginning of the game, the system was divided into ten districts in total, with 2 people in each district. The number of challengers who participated in "Mathematics Breakthrough" was 20.

At this level, the partition logo disappeared, which proved that the challengers who were in different areas in the previous level would be teleported to the area where Tu Hua is now as long as they cleared the level.Even if someone is eliminated during the previous level, the remaining number of passers should be very large, and an area is obviously too crowded.

The number of people who can be sent to this level is really too small, and with the difficulty of the primary level, it shouldn't trap so many people.After a long time, the number of people displayed by the system barely jumped to four digits, and most of the sent challengers were discussing the clearance rate.

Tu Hua tries to find familiar faces in the crowd.I don't know about others, at least he knows all six people in the [Mr. X's Labyrinth] level.In addition to Wang Boyu beside him, he saw Sun Wei who was meditating alone not far away, he also saw the boy who passed the level communicating with other challengers on the other side, and... one of the two girls.

The girl frowned, with a troubled expression, and kept looking into the crowd.

Tu Hua asked Wang Boyu: "Is there some people who didn't send it over?"

Wang Boyu also felt puzzled: "As long as you get the clearance conditions, you can pass the level, such a simple question."

Tu Hua pointed to the girl and showed it to Wang Boyu: "Only one of the two girls who went through the barrier with us came over."

"It's impossible that she can't make such a simple quadratic equation?" Wang Boyu felt unbelievable.

The two went over to inquire, and the girl saw that they were partners who broke through the level together, and she felt an inexplicable sense of intimacy in her heart, and complained to them: "I don't know where Xiaoyu has gone, and I clearly agreed to break through the level together next."

Xiao Yu should be the girl who cleared the level with her before, Tu Hua asked her: "Are you sure Xiao Yu cleared the level?"

"Of course I'm sure!" The girl looked sullen, probably because she felt that her friend had abandoned her, "She came here before me. After she finished answering the questions, I watched her body disappear little by little. Then I quickly did the questions and was sent over."

An ominous premonition suddenly flashed in Tu Hua's heart, and he confirmed again: "Are you sure that Xiao Yu got the question right?"

The girl rolled her eyes: "Please, Xiao Yu gets full marks in every math mock test, how can you do wrong in that kind of pediatric questions!"

She paced back and forth, stomping her feet in frustration, while muttering: "I think she just dislikes me for dragging her down, and doesn't want to team up with me to break through..."

"You misunderstood her." Sun Wei came over suddenly, glanced at Tu Hua, and then said slowly to the girl, "She was eliminated."

"Elimination?! How is it possible!" Not only did the girls not believe it, Wang Boyu also said: "She has found all the clearance conditions like us, and she should pass the level to advance. How can it be eliminated!"

Sun Wei glanced at Wang Boyu, with contemptuous eyes looking at a fool: "Think with your brain and observe with your eyes, don't you find that the way of disappearing through customs clearance is exactly the same as elimination?"

Wang Boyu used to be a well-loved and respected Xueba figure in Pugao, but now being ridiculed by Zhen Xueba, he whispered into Tuhua's ear with aggrieved words: "Is this girl from your school? Why are you so fierce! "

Tu Hua smiled dryly, thinking that you have never seen her more fierce.However, he felt that Sun Wei's judgment was not wrong. Judging from the current status of these challengers who cleared the level, quite a few of them found that their teammates had not been teleported, and they were all in a state of confusion.Those who did not enter the new level had only one ending--elimination.

It's just that Tu Hua still hasn't figured out why these people were eliminated.

"Tu Hua." Suddenly being called by the high-cold student bully, Tu Hua was shocked and cast a cautious look, and then Sun Wei asked, "When you first entered the school, what number did you choose from the guard? "

It was only then that Tu Hua recalled the scene when he was caught by the guard and entered the school. At that time, the guard did give him a number plate with the number "1" and asked him to stick it behind his back, which seemed to have no effect.

Could it be that……

Tu Hua hurriedly showed the number on the back to Sun Wei: "Mine is 1, how about you?"

Sun Wei frowned: "The number I chose is 2."

"What about you?" Tu Hua hurriedly asked the girl and Wang Boyu.

"I chose 2."

"Mine is 1."

really!Tu Hua and Sun Wei looked at each other in astonishment, and they ran to the crowd at the same time, checking the numbers behind the challengers one by one.

There are only two kinds of numbers behind all passers, 1 and 2.And these two numbers happen to be the same as the final answer to the primary level question.

Sun Weining raised his eyebrows: "What's the point of doing this? Are those people just eliminated for no reason?"

"Luck." Tu Hua sighed, "Luck is also a kind of strength."

Su Gechi is definitely not the kind of well-behaved person, so he will never release this kind of chicken soup that as long as you work hard, gold will always shine.No matter how powerful a person is, he still needs opportunities.

It is undeniable that sometimes the 90.00% effort you put in is really no match for the [-]% luck of others.

Wang Boyu looked at the two in a daze: "What are you talking about? What kind of luck?"

Look, this is a typical example of foolish luck, 0% luck.Tu Hua patted him on the shoulder and explained: "At the beginning when all of us entered the game of Mathematics Breakthrough, the gatekeeper at the school gate asked us to choose a number. Randomly choose one of the ten natural numbers from 9 to [-]."

"Actually, your fate was already determined at that time. Only those who choose 1 and 2 can pass the level, and the remaining 80.00% who choose other numbers, even if you are strong, have already been eliminated."

Only then did Wang Boyu come to his senses: "1 and 2? Do you mean the roots of the two real numbers in the primary round? Only those who choose the same number and the answer can pass the level?"

"Yes." Tu Hua nodded, "In this way, it seems that 20 people have passed the test, but in fact only the lucky 2 people participated in the selection. It’s no surprise that very few people reach this level.”

The number of people in the system is still increasing, and it is still unknown whether it can exceed five figures.He didn't have time to lament the injustice of fate, and being able to pass the test proved that he was already one of the lucky ones.But even with luck, the role of strength should not be underestimated, he must put in [-]% effort.

Looking around, Tu Hua saw that all mission levels in the school had been refreshed. The strange thing was that there were side missions everywhere in the school, but there was no main mission in red font.

【Ding--】

[Function-related challenge content: What exactly is a function? 】

[Rules: Challengers can form a team to enter the main level (up to 4 people in the team), and look for functions belonging to this level.One person can pass the customs clearance, the whole team can pass the customs clearance, the time is not limited. 】

The level introduction is very simple, and different from the primary level, there are two buttons at the bottom of the system screen:

【Team clearance】【Evaluation of customs clearance rate】

So is this the reason why there are no main missions on campus this time?As long as you press the [Team Breakthrough] button, you can directly enter the main level of the function level?

It is obviously different from the challenge method of the previous level. They don't need to look for the clearance conditions anymore, as long as they directly enter the level through the system, they can pass the level.But this time, they don't know much about the content of the level. It seems that they are asked to find a certain function in the level, and they don't know anything else.

Tu Hua clicked on [Customs Clearance Rate Evaluation], and the system quickly gave a percentage: 5.4%

Wang Boyu and Sun Wei measured the customs clearance rate to be 2.1% and 4.8% respectively.Wang Boyu was surprised: "It's so low!"

Sun Weidao: "According to the rules, as long as one of the four people in the team clears the level, all members can clear the level. So as long as the sum of the clearance rates of the four people is high enough."

Tu Hua was helpless: "The sum of the three of us is just over 1%."

Wang Boyu: "How about we ask other people? See if there are any thighs to hug?"

Tu Hua was convinced by Wang Boyu's mentality of eating and waiting to die. Before he could open his mouth, Sun Wei said: "Put away your dependence as soon as possible, the ultimate goal of this game is to compete for the qualification for admission to University A. , whose thigh do you think you can hug to get big A?"

Wang Boyu lowered his head resentfully: "Then what should we do?"

Tu Hua looked around at the other side quests in the school, and he knew it in his heart: "I've played so many games, don't you know how to upgrade through dungeons? Do a few more side quests, and the clearance rate can definitely be improved."
