Sure enough, Zhang Shuping never disappoints people when it comes to making troubles, and he announced new rules the next day.

"The next exam will be conducted in groups. Each group cannot be less than five people. The average score of each group is calculated. The five teams with the lowest average score will be eliminated."

After this rule was announced, the children present began to panic, especially those who did not do well in the last exam.

Zhang Liang took the lead in forming his own team, and except for Lu Zhihao, the other three were his followers.

Qin Hao and Pei Zhi also quickly became popular, and many children wanted to join their team.

Lin Zhaoxi stood in front of the two of them: "Sorry, we still have to discuss it."

As he said this, Lin Zhaoxi pulled Qin Hao outside. Upon seeing this, Pei Zhi quickly followed him.

When Lin Chaoxi saw Pei Zhi following him, he hesitated for a moment. Qin Hao said to Lin Chaoxi, "With Pei Zhi here, our success rate will be higher."

"Okay then." Lin Zhaoxi said and waved to Pei Zhi, and the boy ran over and sat down.

"Pei Zhi, can we trust you?" Lin Zhaoxi asked seriously.

Pei Zhi nodded solemnly.

Lin Zhaoxi took a deep breath: "Actually, we do not belong to this world. We traveled from a parallel world. Now we have to go back. This photo is the only clue. According to our analysis, maybe as long as we complete this

By taking photos, you can return to your original world.”

Pei Zhi looked at the photo, but his expression did not change at all. Lin Chaoxi asked cautiously: "You don't believe it?"

"No, I believe it. As long as you say it, I believe it." Pei Zhi said solemnly: "Don't worry, I will definitely help you return to your original world."

Qin Hao couldn't help but raise his forehead. Pei Zhi from the cheese world knew how to flirt with girls at such a young age.

"In this photo, there are a total of twenty-five students including us, which means that there will be 25 students left in the end. Our current number is 45. In the end, 20 students will be eliminated. Zhang Liang and his group will be eliminated.

There is no need for us to worry at all, what we have to do is to form three teams, then bring the ones with the worst results over here, and then help them stay." Qin Hao analyzed.

Lin Chaoxi and Pei Zhidu nodded and approved the plan.

Pei Zhi added: "It is best for us to invite one person with average grades in each group, so that dragging three against each other will not lower the average score too much and avoid being eliminated."

In the classroom, many children looked at Qin Hao and the other two people anxiously. In their expectation, Qin Hao, the three people who usually have the best relationship and good grades, would definitely form a team. There were only two places left in their group.

, if you can join their group, you will definitely be able to advance stably.

When Qin Hao and the others returned to the classroom, several children with quite good grades expressed their desire to join their team.

Qin Hao said to the girl in front of him: "We have not formed a team. Are you sure you want to join my team? The ones I want to form are Yu Tianjiao, Yao Xiaotian, and Shao Mingchen."

The girl was stunned instantly, and the three people whose names Qin Hao read were also stunned on the spot.

Yu Tianjiao asked cautiously: "Qin Hao, did you just say you wanted to form a team with us?"

Qin Hao smiled at her: "Why, you don't want to?"

Yu Tianjiao waved her hands repeatedly: "No, how could it be? I just don't understand. It's obvious that the three of you are more likely to win first place as a team, why would you team up with us?"

Qin Hao spread his hands: "It's nothing, I just don't like this kind of rule that treats people as examination machines. If you don't have any meaning, then we will form a team."

The girl thought for a while and finally gritted her teeth and joined Qin Hao's team.

Zhang Liang mocked disdainfully: "Humph, you self-righteous guy trying to go against the rules is simply stupid. Soon all three of you groups will be eliminated."

Qin Hao glanced at him: "Do you know what the difference is between geniuses and ordinary people? Geniuses will never live by the rules set by others. People like you only seek advantages and avoid disadvantages in everything, and act according to other people's rules.

, you will never reach the height of genius in your lifetime."

"You!" Zhang Liang's face turned red after being yelled at. He now felt that Qin Hao was even more annoying than Pei Zhi. This guy's mouth was too poisonous!

Soon the team formation of Pei Zhi and Lin Zhaoxi was completed, and the third team handed over the list to assistant coach Xie Ran.

After Zhang Shuping got the list, he couldn't help but feel a little annoyed. Although he was resentful about Qin Hao humiliating him in public, he had to admit that both Qin Hao and Pei Zhi were geniuses. In his opinion, geniuses should be grouped with geniuses.

, so that his teaching work can be easier.

But Qin Hao and the others not only did not form a team, but each of them brought the students with the worst grades.

Jie Ran said with some worry: "Teacher Zhang, do we need to change our exam rules, or just eliminate the last team? Qin Hao, Pei Zhi, and Lin Zhaoxi are definitely the smartest in our class.

Three children."

Zhang Shuping shook his head with a cold face: "Smart people shouldn't use stupid methods. This is their own choice. Even if they are eliminated, they can't blame others."

.......

After the grouping was completed, Zhang Shuping took everyone to the library: "This bookshelf is your future study scope. I have asked Assistant Professor Xie to help you make an outline. Next, you have to find out who you are from this outline.

The knowledge points that need to be learned will also be the focus of our exams in the future.”

The children were all dumbfounded. In the past, they would learn whatever the teacher taught them, but now Zhang Shuping doesn't even give them books and lets them learn by themselves. This is a bit too difficult for them.

Even Zhang Liang was a little confused, but Qin Hao had already taken the lead in receiving the outline and walked into the bookshelf to start selecting books, followed closely by Pei Zhi.

After Pei Zhi distributed the books to the group members, Zhang Shuping asked: "Classmate Pei Zhi, tell me the basis for your selection of these books."

Pei Zhi was about to say it, but Qin Hao stopped him: "Since Teacher Zhang wants to test everyone's self-study ability, you shouldn't spoil it."

Zhang Shuping failed to pretend and glared at Qin Hao. Qin Hao was too lazy to pay attention to him and summoned his team members to the desk. Lin Chaoxi also sat down with his team members. Pei Zhichong bowed slightly to Zhang Shuping and also led his team

The staff moved the tables together.

"This syllabus has actually divided the scope, including counting, filling in pictures and splitting numbers in the first grade, understanding simple sequence and natural number sequence in the second and third grade, and finding patterns in number tables in the fourth and fifth grade.

The book is all about numbers, and these contents are all in it.”

Saying that, Qin Hao paused and asked, "Do you know the origin of Mathematical Olympiad?"

Yu Tianjiao raised her hand and said: "I know that the Hungarian mathematics community organized a mathematics competition in 1894 to commemorate the mathematician Ertwás Roland."

Qin Hao nodded and asked: "Then do you know the biggest difference between the Mathematical Olympiad and the mathematics we usually learn?"

Everyone shook their heads in confusion.

"The Math Olympiad is more difficult, while mathematics is relatively easy."

Qin Hao smiled: "You can say that. In my opinion, mathematics is like a highway, and Mathematical Olympiad is one of the highways. No matter what the maximum speed of each highway is, it will eventually converge to mathematics."

On the main road."

"When we study Mathematical Olympiad, on the one hand, we need to master its knowledge points, and on the other hand, we need to learn to break out of the conventional thinking in mathematics to solve problems."

"For example, a commonly used problem-solving idea we encounter in school is to set up unknowns and use one-yuan or two-yuan equations to solve problems. However, Olympiad math problems rarely use unknowns, but use simpler logic and mathematics to solve them.

question, what we have to do now is to change our thinking, liberate our thinking, put down those equations, use Olympiad thinking to look at those problems, follow the problem-solving ideas, and find their laws..."

After listening to Qin Hao's words, some children looked confused, some were thoughtful, and some suddenly understood.

Zhang Shuping walked out of the library quickly, and assistant teacher Xie Ran cast an appreciative look at Qin Hao.

Zhang Liang curled his lips disdainfully after listening: "I thought I had any great ideas, but that's all."

When Yu Tianjiao heard this, she glared at Zhang Liang: "Don't make sarcastic remarks there. You can only study well by yourself. Can you help others improve?"

"That is, with Qin Hao and Pei Zhi here, you will never get the first place in the exam. What's the point of being proud of?"

Zhang Liang was furious: "You guys!"

Qin Hao didn't have time to waste time with Zhang Liang, the middle school boy, and started talking about specific examples directly.

"For example, this question: The school bought 4 tables and 6 chairs for a total of 640 yuan. The price of 2 tables and 5 chairs is the same. What is the unit price of the table and the chair?"

"Let's put aside the equation, what should the problem-solving idea be? Based on the condition that "the price of 2 tables and 5 chairs is equal", it can be deduced that 4 tables are equivalent to the price of 10 chairs. Buying 4 tables

Sharing 640 yuan with 6 chairs is equivalent to buying 16 chairs and sharing 640 yuan.”

“So, the problem-solving process should be:

Solution: 5x(4÷2) 6=16 (hands)

640÷16=40(yuan)

40x5÷2=10O(yuan)

Answer: The unit prices of the table and chairs are 100 yuan and 40 yuan respectively."

Qin Hao paused for a moment: "This is the problem-solving thinking of the Mathematical Olympiad. Putting aside those advanced tools, it is as if the method of setting equations has not yet been born. We have to summarize the rules of this problem ourselves, and then solve the problem."

Amidst the applause, Lin Zhaoxi looked at Qin Hao talking eloquently, and suddenly felt that this guy looked like Lao Lin.

A week later, the first test after grouping was conducted. Zhang Liang's group got the first average score, while Qin Hao and Pei Zhi's group ranked third and fourth, and Lin Zhaoxi's group ranked fifth. Three more groups of members were eliminated.

, that is to say, there are only 30 team members left.

Judging from the follow-up, there should be only five elimination places, but the more this happens, the more dangerous it is. Once a child is eliminated, the photo cannot be restored, and Qin Hao and Lin Zhaoxi will not be able to return to Strawberry World.

"What do you think?" Lin Chaoxi couldn't sleep at night, so she pulled Qin Hao out again to discuss countermeasures, but Pei Zhi shamelessly followed him.

Qin Hao said with relief: "Zhang Liang's team is basically stable. We don't need to worry. As for the average score of the members of the second group, it is also higher than us. What is more troublesome is the group ranked sixth this time. There are three people in this group.

The first one is a photo member, and we’d better add them to our group, but their results are not very good, and I’m afraid it will lower our average score. If one of our teams is eliminated, all our efforts will be wasted.”

"Then we will try to persuade them to join our group tomorrow." Lin Chaoxi said, and Pei Zhi also began to agree.

Qin Hao shook his head and said: "I think the key is not how to persuade them to join, but how to persuade the existing team members to accept them."

Lin Zhaoxi was silent. She knew that when people's own interests are involved, they often only consider themselves. This is nature.
