The little fat man who was absent-mindedly doing the English proficiency test paper looked at Lu Xi, who was staying there motionless like a goose, and couldn't help but feel proud.

Hmph, what about the Olympiad questions in elementary school? Even if you are a high school student and you are still attached to Hwaseong No. 1 High School, if you don't have training in this area, you won't be able to do it with your elementary school arithmetic knowledge.

The reason why the little fat man is so confident is that on several occasions before, he used the same elementary school math problem to stump many college students who used their spare time to work as part-time tutors.

In fact, Lu Xi was stunned there at all, and he was stumped by the topic.

It's just that when she saw the first question in the paper, a very classic elementary school Olympiad math question, she remembered an interesting scene in a movie.

This problem is the problem of chickens and rabbits in the same cage: the cage contains a number of chickens and rabbits, a total of 100 legs, if the chicken is replaced with a rabbit and the rabbit is replaced by a chicken, a total of 92 legs. So how many chickens and rabbits are there in the cage?

This type of question, which has a long history and tradition, is indeed easy to get the answer if you use a one-dimensional equation or a system of two-dimensional equations, but under the premise of limiting the arithmetic knowledge of elementary school, it is really not so easy to write the solution process if you do not learn the solutions and ideas.

From this point of view, the little fat man is cunning and cunning.

With the trick of dealing with the tutor, the little fat man is very relieved to deal with the English proficiency test papers. I don't know if it's a good mood, but he found that his efficiency was actually higher than usual. A lot of questions that I don't know can be done one by one at this moment.

It's just that after all, the foundation of English is not good, and no matter how extraordinary the level is, it is impossible to score 100 points with a foundation of 50 points.

In the English proficiency test paper produced by Ao Xue, he can probably make 50% of the questions, and the rest can only be guessed.

Of course, if you have good English, there is no need to ask for a tutor.

"Will it not be done, or will it take more time?"

When he was struggling with the questions that he couldn't do later, the little fat man heard a voice from behind, looked up, and saw that very beautiful face.

Fang Juezhi likes beautiful things, but the little fat classmate also knows the famous saying, life is precious, love is more valuable, if it is for freedom, both can be thrown.

The tutor's extracurricular tutoring is generally carried out on Sundays, which will undoubtedly make him lose the most precious free time, which is the main reason why the little fat student hates tutoring so much.

For freedom!

No matter how beautiful a tutor is, it is also a tutor. The mouth of the green bamboo snake, the needle behind the wasp's tail, both are not poisonous, the most poisonous woman's heart, the little fat man made up in his heart, and then tried to say in a nonchalant tone: "I won't do it, it will take more time." ”

Lu Xi glanced at the little fat man, and said to himself: "There are so many that I can't do, it seems that I need to make up for the class." Today's children are just too inattentive, picky eaters, learning partial subjects, as a primary school student, how can they not develop in an all-round way, and they can't be admitted to the junior high school of Huafu. ”

The little fat man was stimulated by Lu Xi's words, and his chubby face turned red, but he still asked very stiffly: "What about yours, have you finished the test paper?" ”

Lu Xi raised the scroll in his hand and said: "I finished it early, I waited for half an hour when I saw you so distressed, who knew that in half an hour, you still won't be able to do the rest of the questions, what, you need to check it?" ”

"Show me." The little fat man snatched the roll and quickly looked at the answers on it.

The question of chickens and rabbits in the same cage, there are 4 rabbits and 42 chickens, and the answer is correct; The next one, the side length question, 4 cm, is also correct......

The above questions are all found by himself, and the answers are all in his head, so he can get the correct result as long as he sees it. However, what he didn't expect was that all the questions were done correctly and completed quickly and well.

Two of these questions were done by my grandfather, who is a professor in the Department of Mathematics of Huacheng University, and may not be able to do it in such a short period of time with the arithmetic knowledge of primary school. The little fat man was speechless and roared to the sky.

Freedom was about to be snuffed out, and he was depressed and depressed.

"I really don't know what you elementary school students think, you are obviously an English tutor, but you give math problems, if it weren't for my flexible head as a tutor, I would have almost capsized in the gutter. However, Fang Juezhi classmate, if you want to test your teacher and my level, you should also use high school questions. Now schoolchildren, alas, what a ......"

It's boring, it's good to tease elementary school students to make themselves happy, Lu Xi thought lazily.

The little fat man was almost embarrassed, and gritted his teeth angrily: "You said that your math level is very high, then okay, I'll give you some more questions." ”

Lu Xi smiled contemptuously: "I'm here to help your tutor teach you English, not to help you do math problems." ”

The little fat man who was thinking about it stubbornly said: "I also need some extracurricular tutoring in mathematics. ”

"What are you going to do if I help you with all the questions?"

"I'll do what you want me to do."

"Obey?"

"I'll listen to you."

"Including your official tutor?"

Unable to give up the child and can't trap the wolf, Fang Juezhi made up his mind ruthlessly: "All." ”

Seeing that the little fat man was so well-behaved, Lu Xi nodded with satisfaction: "Well, the gentleman is quick to say a whip, then the word is decided, take out the topic, your teacher and I are in a hurry." ”

"Wait a minute, I'll get it and I'll come." The little fat man said and rushed out of the study.

This Huafu woman, the primary school Olympiad questions are so smooth, it is likely that she was born in mathematics, so even the most difficult Olympiad questions may not be able to stump her, I need more difficult math problems, don't you say that your math level is high, then I will let you know what the real math problem is.

Thinking like this, he glanced at the living room, where his grandfather was still reading intently, so he stood on tiptoe and quietly opened the door of his grandfather's study.

A moment later, the little fat man walked in with a blank math paper.

Lu Xi said a little impatiently: "Take the speed of the question, solve it and start lecturing." ”

The little fat man slapped the test paper on the table, shook the fat on his face, and shouted: "This is it, if you can finish it all, then I will take you, the five-body service." ”

"Yes." Lu Xi said and took the scroll.

Hmph, do you think I'll let you pass the test so lightly, I can't do it after a while, and I'll make a fool of myself in front of my students, and see what face you have left to be a tutor.

The little fat man thought to himself, his eyes were fixed tightly, as if he was worried that Lu Xi would cheat if his gaze shifted a little.

I heard that the real tutor is still a student in the first year of high school, so this is a classmate of the regular tutor teacher, and the temporary tutor is naturally also a student in the first year of high school. He didn't think that a freshman in high school had already learned advanced mathematics.

He didn't think about it at all, even if Lu Xi couldn't do those math problems, the English tutoring class would still be very sad and normal. In this family, it is not his turn to call the shots.

In addition, what the little fat man doesn't understand is that there are so many college students who work part-time as tutors, why would grandpa invite a high school student to teach him. High school students, no matter how high the level is, can they be higher than college students?

Of course, he didn't know that the higher the level of the tutor, the better, as long as the level is enough and suitable, it is the best. What's more, Aoxue's English level may be better than most college students.

Over there, Lu Xi, who was holding the paper, could see at a glance that the papers were all about advanced mathematics, but she wanted to convince Aoxue that this troublemaker, unruly little fat man, so she remained silent and pretended not to know and buried herself in the answer.

Compared with Lu Xi's impassivity, the little fat man next to him became more and more frightened the more he looked at it.

Because he found that Lu Xi's speed of doing the questions was too fast, and there was just one.

It's just that what makes him feel annoyed is that he doesn't know if Lu Xi's answer is wrong or not. Because it was a math test paper he stole from his grandfather, he recognized the words on it, but when combined with various mathematical symbols, he didn't know what it meant.

He is still a primary school student, and no matter how good he is in elementary school Olympiad, even if he is advanced in mathematics, it is far from being able to reach the level of advanced mathematics.

In fact, the papers are all calculus problems of average difficulty.

Lu Xi is studying advanced mathematics on her own, and her current learning focus is not on advanced mathematics, so she just used her spare time to watch, and after a cursory look at the Tongji version of advanced mathematics, she is watching the super advanced version, Zhuo Liqi's mathematical analysis.

In terms of exercises, she bought a set of exercises called "Jimidovich Mathematical Analysis Workbook", which is a well-known workbook for mathematical analysis. But because of the time relationship, I didn't do much, and I didn't do so many questions every day like the math competition questions.

And when she browsed this set of exercises, she felt that the level of this set of exercises was not so consistent with its famous name, mechanical repetitive thinking, massive calculations, and not much benefit from thinking.

On the contrary, it is the problem behind Zorich's mathematical analysis, and it feels better to do one or two questions occasionally when the interest comes.

It's just that even if she didn't do much practice, the questions on the paper were still easy for her to do.

In less than ten minutes, more than 10 questions were completed in one stroke.

When Lu Xi handed over the finished roll to the little fat man, the little fat man was stunned, and suddenly shouted: "That's it, that's it, it's done, it's done." ”

If he shocked Perelman or Tao Zhexuan in mathematics, Lu Xi might still feel good, but it would surprise a primary school student......

However, Lu Xi thought about it, then looked at the little fat man with interest, and asked, "The Fang family's math genius, do you want to correct it now?" ”

"Wait, I'll take it for correction and I'll be back soon." The little fat man stammered, and after saying that, he stumbled out the door with the roll.

in the living room.

The little fat man holding the densely written volume hesitated for more than ten seconds, and then walked to Fang Lao's side and asked cautiously: "Grandpa?" ”

Old Fang's eyes raised slightly, his eyes looked through the gap on his glasses, his eyes looked at Fang Juezhi's classmates like a sword, and asked in a very stern tone: "Aren't you taking English tutoring classes, you always run around, what are you doing, don't you want to learn again?" ”

In this family, Fang Juezhi is not afraid of his classmates, and he doesn't even care about his parents, he is afraid of this grandfather who is very strict and old-fashioned.

Hearing his grandfather's stern questioning, his heartstrings trembled, and he swallowed a mouthful of saliva with difficulty, he was ready to accept his grandfather's thunderous wrath, but now that the arrow was ready to be sent, he could only bite the bullet and say: "Grandpa, this, this, I, I want you to see, take a look." ”

"What is this?"

Fang Lao took the thing handed to him by his grandson noncommittally, and when he opened it and looked at it, his brows condensed into Sichuan characters.

"Isn't this my math paper, where did you get it from?"

"I, I ......" Fang Juezhi regretted it.

"Who made the title?" Seeing his appearance, Elder Fang thought of the ridiculous things he had done before, and he didn't know what was going on, so he didn't plan to investigate him for rummaging through his own things.

"Yes, yes, it was done by Mr. Lu." Fang Jue knew that if the classmate didn't show that he had to be well-behaved, the whip was about to fall.

"Oh, it's upstairs, your Sister Lu Xi?"

"Yes, grandpa, did you do it all wrong?"

"Who said it was wrong?" Old Fang's eyes widened, he had already read three questions, and the answers were completely correct.

"Isn't it?" The little fat man touched his head and wondered.

Fang Lao glared at Fang Juezhi, and said sharply: "This is my question, it's wrong, I don't know, you still know?" ”

Fang Juezhi hurriedly shrank back: "You know, you know." ”

Over there, Elder Fang returned his gaze to the scroll, pondering as he looked at it.

While Fang Lao was pondering, Fang Juezhi muttered, "It's really even possible to do math problems in college, is it so exaggerated?" ”

Half a sound, Fang Lao, who came back to his senses, said slowly: "You, Sister Lu Xi, have learned mathematics very advanced, it seems that the tutor I invited this time is the right one." ”

That's right, but isn't Sister Lu Xi a temporary tutor in place of a genuine tutor, no matter how good the math is, it may not be able to teach me for many days, and what I need most is not English tutoring, but math? Fang Juezhi complained in his heart.

Fang Lao didn't know that Fang Juezhi was thinking about these things, he said that when he saw that Fang Juezhi was still stunned, he immediately shouted: "What will be messed around, don't you go in and study, what is the pestle doing here, is it a door god?" ”

Then Fang Jue knew that the classmate wolf bèi left.
