Mathematics Olympiad questions

Jiang Shixin and Jiang Ye were still talking and laughing when they came up, and the people who hadn't seen them had already heard their voices.

It greatly attracted the dissatisfaction of the people around him.

Finally, when the three of them appeared at the top of the stairs, a boy in the third year of junior high school couldn't bear it anymore and stood up and walked in front of them.

Looking at them condescendingly: "This is the library, please be quiet." ”

The three of them paused at the same time.

"Do you have any comments?"

Jiang Shixin raised his eyebrows, although his height was more than half a head behind the boy in front of him, his aura was not weaker than him at all.

Don't look at the fact that he is a brother to everyone on weekdays, it feels like he has a good temper.

In fact, it's quite the opposite.

He's a guy who blows up at all.

And Jiang Ye next to him will be relatively calm, just able to drag Jiang Shixin a little when he explodes.

But if he really got it, he would never admit it.

[Hey, how do you feel like you're going to fight, be careful of being discovered by the teacher, but you have to demerit! ] 】

[Why didn't I find out that Jiang Shixin's temper was so short-tempered? I thought he was the kind of courtesan who could talk to anyone. 】

[Isn't that good?] Someone to stop them. 】

Seeing that the two sides are deadlocked.

Ji Ye sighed and stepped forward to block between the two.

"Sorry, we'll be quiet."

just gave the boy in the third year of junior high school a step down, and he didn't continue to stalemate with them, so he came down.

"Hmph."

The boys all left, and only Jiang Shixin was still holding his breath: "Why are you apologizing to him?" I'm not afraid of him if I want to fight! ”

Jiang Ye glanced at him silently beside him, and said quietly: "You still want to fight?" Have you forgotten what your aunt said? If you fight again at school, your pocket money will be cut off, and all the things you promised to buy you will be nullified. ”

Jiang Shixin: "......"

Ji Ye also said one more sentence: "And do you want to fight in front of your boss?" ”

As he spoke, he also pointed to Lin Jiayi, who was looking at them with resentful eyes not far away.

Jiang Shixin shrank his head, and he was glad in his heart.

Fortunately, I didn't have impulsiveness, otherwise I would not only be cut off from my pocket money, I wouldn't be able to buy what I wanted, but I would also be hated by the boss.

"Okay, sorry, I was too impulsive." Jiang Shixin simply admitted his mistake.

He treats his brothers and friends with absolute care 100%.

After what happened just now, Jiang Shixin couldn't help but feel a little weak.

Follow behind Ji Ye and block himself with him.

Lin Jiayi glared and was about to say something, but Ji Ye quickly took out a bottle of cold peach-flavored sparkling water from the bag and handed it to her: "Your favorite peach-flavored sparkling water." ”

Looking at the sparkling water handed to him, what Lin Jiayi wanted to say instantly choked in his throat.

After holding it for a while, he reached out and took the sparkling water and slowly spit out a few words: "Don't take it as an example." ”

Ji Ye gave Jiang Shixin a look behind him, and Jiang Shixin immediately sat down obediently in the opposite position, took out all his homework and books and laid them out on the table in a proper manner.

Like a child who has made a mistake and flatters after the fact.

[Hahahaha! Jiang Shixin, how did you look like just now? Why did you get cowardly in front of Jiajia baby in an instant? 】

[It seems that Jiang Shixin has a strong sense of class, the boss is the boss, no matter how much he jumps outside, he doesn't dare to jump in front of the boss. 】

[Hahahaha! It seems that Jiang Shixin is also very afraid that Jiajia Baby will be angry. 】

Lin Jiayi's temper when she first came up disappeared all of a sudden.

She was so angry that she wanted to laugh.

But we can't afford to lose ground now.

I had to hold back a smile and arrange a seat for them.

The desks in the library are rectangular and can seat a dozen people on one sheet.

Lin Jiayi, Ji Ye and Hua Chao sat in one row, and Jiang Shixin, Jiang Ye, Le Ya and Song Siqi sat in the opposite row.

This also makes it easier for her to talk about the topic.

"You guys do today's math homework first, and I'll review the content of the first and second grades for Le Ya and Ah Qi first."

Jiang Shixin and Jiang Ye listened to her words, and obediently took out their homework books and buried themselves in the questions.

Ji Ye and Hua Chao also took the Olympiad questions they took from the teacher and buried themselves in the questions.

Lin Jiayi's deliberately lowered voice echoed lightly in the ears of several people.

Although she lowered her voice, it did not affect her speed and clarity at all, and she finished all the knowledge of the first and second grades before Jiang Shixin and Jiang Ye finished their homework.

"You guys should also take out today's homework and do it first."

Lin Jiayi took out today's homework book from her schoolbag, and a paper similar to a test question was slid out of her schoolbag with the homework book.

"Huh? What is it? Lin Jiayi picked up the piece of paper and looked at it.

It turned out that the math teacher had premeditated and sandwiched the test papers of the Olympiad questions in her homework book and sent them down.

And it's not just one, there are five test papers.

There is one Olympiad question for the third, fourth, fifth and sixth grades, and one is actually the question of last year's National Olympiad Mathematics Competition, and the questions of the two days are printed on one.

How much did the teacher expect from her to put this paper in her homework book?

[What is this?] National Mathematics Olympiad Competition? I'm going, is it appropriate for a seven-year-old to do this kind of problem? 】

[No matter how smart Jiajia baby is, the title of this paper is also out of outline, right? ] 】

[That's right, this is an Olympiad competition topic that college students can participate in, Jiajia baby is only in the third grade, shouldn't be able to do it? ] 】

[Can't do it or on the one hand, on the other hand, will it hit our Jiajia baby's self-confidence? ] 】

Her scroll attracted the attention of Ji Ye and Hua Chao on both sides.

"National Mathematics Olympiad test papers? Where did you get the exam papers? ”

Ji Ye was obviously very interested in the test paper in her hand.

"I guess my math teacher has it in my workbook." Lin Jiayi thought about the math teacher's expectant gaze, and felt a lot of pressure.

She's really not that good!

It's far worse than my brother!

"You wait a while, don't write it yet, borrow me to make a copy of this test paper." In the blink of an eye, Ji Ye threw away the sixth-grade Olympiad question paper that he had almost written.

He can basically see the answer to an Olympiad problem of this level, there is no challenge at all, it is too boring.

"Eh, I want it too, I want it too!" Hua Chao immediately raised his hand.

The third-grade math Olympiad in his hand was completed at once.

It's not difficult at all.

Of course, Lin Jiayi has no problem: "There seems to be a photocopier on the first floor, you can go downstairs to copy." ”

"I'll go." Ji Ye took the test paper and walked downstairs.

Lin Jiayi was worried about the four scrolls in front of her, not that she wouldn't do it.

It's a bit of a waste of time to do something so simple.

It's also a little interesting that the National Mathematics Olympiad test paper that Ji Ye took away.

But there is no way, the teacher has given it to her, and it is also an expectation for her, she can't hand in a blank paper, right?
