Quiet!

Absolute silence!

Wu Linli was extremely excited in his heart, he really didn't see the wrong person, the title of this prodigy really didn't cover it, he was really too good!

Xu Jiaojiao's face showed a huge look of surprise, she couldn't have imagined that this child hadn't spoken, it turned out that she was really doing mental arithmetic, she originally thought that Wu Linli's words just now were just a joke, but she didn't expect this five-year-old child to really do it.

It's amazing, it's terrifying!

Zheng Binxi's plain face suddenly surged with an inexplicable fluctuation, the emotions in her heart at the moment were very complicated, the demonic ability shown by this five-year-old child really overshadowed the honor of her whole body.

She used to be the pride of this school, the god of mathematics, she was a top student in the eyes of countless teachers and students, and she was a demon angel in the eyes of the elites of various primary and secondary schools in the Olympiad.

But now, she doubts herself, and she feels that her self-confidence has been severely damaged.

She had to prove herself, she had to defeat this nasty kid she couldn't forget.

Thinking of his arrogant and cold expression in front of him, Zheng Huanxi was inexplicably restless in his heart.

"Fantastic, exactly. Wu Linli said excitedly.

Xu Jiaojiao was silent for a moment and asked, "How did you come up with this answer?" ”

Before Sun Mohan could speak, Wu Linli smiled and said, "I'm sorry, my students have a habit of only focusing on the final result and not liking the explanation process." ”

Xu Jiao's squeamish silver teeth clenched, but it was useless to say more at the moment, she underestimated this five-year-old child too much.

"What are you proud of, the competition is not over yet, come up with your questions. Xu Jiaojiao snorted.

Wu Linli smiled, then walked to the blackboard and began to brush and write.

"The owner of a bookstore went to the book wholesale market to buy a certain kind of book, and the first time he bought a book, he spent 100 yuan, and sold it at the price of 2.8 yuan, and it was sold out quickly. When buying books for the second time, the wholesale price of each book increased by 0.5 yuan compared with the first time, and the number of books purchased was 10 more than the first time, and when the books were sold 4/5, the remaining books were sold at a 5% discount on the list price. Let's ask the boss whether he loses money or makes money on the second book sale, if he loses, how much he loses, and if he earns, how much he earns."

After writing, Sun Mohan fell into thought, and Zheng Hanxi quickly picked up the pen and calculated.

In order not to disturb these two people, Xu Jiaojiao and Wu Linli walked outside the door, because this question could not be calculated for a while.

Xu Jiaojiao lightly slapped Wu Linli and said, "What do you mean, with such a difficult question, the two of them may not be able to solve this question, and this question has risen to the level of junior high school." ”

Wu Linli put his hands on Xu Jiaojiao's shoulders and said affectionately: "I just want to see how powerful these two people are." ”

Xu Jiaojiao snorted and said, "But if you do this, the agreement between the two of us may be a draw, what about the housework and cooking for these two scholars?"

Wu Linli stroked the hair on Xu Jiaojiao's ear, and said helplessly: "I didn't expect you to do housework and cook, didn't I say that just now to arouse that child's fighting spirit, our family, what is my status, how dare you let Teacher Xu cook by yourself, even if Sun Mohan really wins the proud girl you bring, I will still cook the dishes." ”

Xu Jiaojiao blinked and smiled: "Count your acquaintance, this Sun Mohan is indeed a prodigy, so big, so powerful in mathematical thinking, it's incredible, in fact, you can discover such a little genius, I'm really happy for you, the only thing I'm worried about is that if this kid loses, it will completely hit her self-confidence." ”

Wu Linli comforted: "Don't worry, Zheng Binxi's child will not be so easily defeated, and even if she loses, it will not be a bad thing for her, her road has been too smooth over the years, if someone can really hit her a little, maybe she can move to a higher level." ”

Xu Jiaojiao sighed and said, "I hope so!"

In the past twenty minutes, Zheng Binxi finally solved the answer, two full sheets of A4 paper, dense, quite complete and detailed, and also listed two solutions.

Xu Jiaojiao glanced at it a few times, and couldn't help but admire: "Huanxi is still the same Huanxi, it's great, the teacher is proud of you, even if this question is placed in the entire Xueersi Cup Mathematics Olympiad Grand Prix, there may not be a few primary school students who can solve it." ”

Zheng Hanxi's face was indifferent, there was no expression of joy at all, she kept staring at Sun Mohan opposite, even if she solved it, it was not a big deal, only by defeating Sun Mohan could she regain her self-confidence.

Wu Linli looked at Sun Mohan, who was a blank piece of paper again, and couldn't help but shake his head, could it be that this guy is doing mental arithmetic again?

Impossible, absolutely impossible, the process of this question is quite complicated, even if it is yourself, it is impossible not to calculate without writing.

Xu Jiaojiao also thinks the same way, compared with the question she came up with, this question is not only much more difficult, but also has a lot of complicated processes in the algorithm.

"Two teachers, this question is a bit difficult, I gave up!"

Sun Mohan had a slightly depressed little face, stood up and stretched, and then walked up to Zheng Yuxi and smiled slightly: "School flower, congratulations, you won!"

Zheng Huanxi paused for a moment and stammered, "You ...... You're pretty ...... too. It's amazing!"

Sun Mohan smiled, then waved his hand at Wu Linli and Xu Jiaojiao and said, "Teacher Wu, you and Teacher Xu have to have a good time, don't fight because of this matter, I'll continue to go back to take a nap." ”

After saying this, Sun Mohan left the office directly, Xu Jiaojiao sneered and said: "I like this kid too much, not to mention smart and cute, and humorous cells, Wu Linli, is this time a defeat?"

Wu Linli smiled and said: "Serve, how can you not accept it, the agreement is valid, I will go back to wash your socks after work." ”

"Zheng Binxi, you are worthy of the king of mathematics in our Xiangyang Primary School, and I hope you can win the championship in the Xueersi Cup Mathematics Olympiad next month, drawing a perfect end to your primary school career. Wu Linli turned around again and congratulated Zheng Binxi.

Zheng Huanxi smiled and said: "Thank you Teacher Wu for your encouragement, in fact, Sun Mohan is really good, he is only five years old after all, if he reaches my age, it is estimated that he will be better than me." ”

"Victory but not arrogance, not bad, good, the teacher is optimistic about you. Wu Linli continued.

Xu Jiaojiao smiled: "Okay, okay, don't show off your thick black school in front of my students, let's go, tomorrow the teacher will bring you crayfish, and you can also taste Teacher Wu's craftsmanship." ”

Zheng Weixi smiled shyly and followed Xu Jiaojiao out of the office.

Wu Linli sat alone at the desk in the office, holding the two manuscript papers calculated by Zheng Binxi, reading them over and over again, and couldn't help but admire in his heart, a girl actually has such strong mathematical thinking, which is really against the sky.

As for Sun Mohan, he also thinks it is very good, because he not only sees hope from this child, but also sees a very free and easy spirit, which is too precious in the current group of strong children.

Although Sun Mohan didn't solve it, he generously admitted defeat and congratulated his opponent, an emotional intelligence that even many adults don't have.

Wu Linli made a cup of black tea, took two sips of it comfortably, and then brought the trash can, ready to take out the garbage, but just when he was about to pick up the garbage bag, he saw a small paper ball that was pinched into a ball, Wu Linli is a careful person, he clearly remembered that there was no paper ball in the trash can before.

So he picked up the paper ball, opened it with great difficulty, smoothed it out, and shocked him with its contents......

"This ...... This kid had already figured out the answer, and it only took four or five steps to solve it, but ...... But why should he throw in the towel?"

Wu Linli patted his head, very puzzled......
