Tang Xiaoya was so angry, she bent over and pouted her ass to hold a broken little flower, but she was bumped and pushed there, which was really hateful.

"You bastard. She looked like she was going to hit someone, and the taekwondo starting style came out, and she came up with a side kick directly, which was very fierce.

Liu Sen was stunned, and the girls in the university were too spicy, and the capture formation was activated, thanks to the improvement of physical fitness during this time, they were all avoided in advance.

Tang Xiaoya missed four blows, obviously refusing to let go.

"Didn't I just accidentally hit you? and a lot of meat, I have to entangle something. ”

"You just hit me on purpose, a student doing such a shameless thing. ”

Liu Sen really didn't pay attention to where he bumped into her, and offended Tang Xiaoya miserably.

It's hitting the ground that shouldn't be bumped into the most, and it's not close to each other through two layers of pants, can you not be angry?

Liu Sen had a brain teaser and shouted, "I'm sorry, I'm thinking about math problems, I really didn't notice you." ”

"What's the topic? Hmph, you must be a garbage person at the level of your trash, think about it. ”

Tang Xiaoya stared at him hatefully with a pair of beautiful eyes, obviously trying her best not to do it, several classmates looked at him when they walked by, and it was indecent to fight again, especially if she couldn't hit.

Just when a few boys walked by, Liu Sen received dozens of points of spiritual power, and he couldn't help but feel excited.

"I'm thinking about math, it's hard. ”

Liu Sen shrugged his shoulders and was helpless when he saw that there was a door, this girl appeared here, it should be the Department of Mathematics, it is undoubtedly good-looking, the thief's eye unconsciously used the capture array diagram, and looked at the generated data, tsk, the figure is still so good, the waist is slender, and the arc is perfect.

The face still looks very immature.

It should be the kind that undoubtedly attracts the attention of countless students.

"What bullshit are you thinking about?"

"It's a very difficult question, you can't understand it. ”

Liu Sen squinted his eyes and deliberately provoked her.

Tang Xiaoya is a well-known student in the Department of Mathematics, the flower of the department, her father is also a well-known professor of mathematics, almost every boy in the Department of Mathematics wants to pursue her, and one pursuit is particularly fierce and she was beaten, which can't kill the enthusiasm of male classmates, and there are other departments, but the girl hasn't pretended to any boy yet.

"What are you talking about?!"

Tang Xiaoya squinted her eyes and emitted a dangerous light, and the evil fire that was hit had nowhere to vent, as a scholar and a school idiot, she still had great curiosity.

"It's too hard, and you won't be able to. ”

Tang Xiaoya's breathing was a little rougher, and she hated to kick this guy to death, but it was useless to keep her feet out just now, the stinky guy's body was very flexible, he took a breath, his face suddenly became gentle, and said: "Presumably you are also a student of the mathematics department, why don't we try it and ask each other questions, if you can't solve it, just stand still and let me kick my feet." ”

"What if you lose?"

"Will I lose?" Tang Xiaoya snorted as if you were new here, "Then what do you want?"

"You stand still, let me touch two. ”

"You ......" the long legs kicked over.

Liu Sen dodged and hurriedly said, "Just kidding, do you still have class today?"

"There is a "Higher Mathematics" class in the evening, what do you want?"

"Is there a lot of people in the class?"

Tang Xiaoya didn't understand what he meant, and frowned: "The whole department is a freshman, Teacher Li is very strict, no one dares to skip class, nearly 300 people." ”

That's really good, Liu Sen's ghost brain moved, and said: "If you lose, I'll go to class with you, sit together, and if someone asks, you will say I'm your boyfriend." ”

The emotions of college students are even more abundant, and there are so many people, maybe they will be full of spiritual power.

Tang Xiaoya pondered for a while, and said fiercely: "Okay." ”

It's refreshing!

Liu Senle said: "Aren't you afraid that I will regret it?"

She raised her mobile phone and showed a smug smile, "I recorded it, hmph, if you dare to regret it, you will become famous at the Normal University." ”

Liu Sen also laughed and shook his phone.

The two of them actually thought of a piece, Tang Xiaoya's face sank, and she shouted, "Who will ask the question first?"

"Of course I came out first. ”

Shameless, he didn't understand the principle of lady first, Tang Xiaoya despised him fiercely in her heart.

Liu Sen took a step back and said: "There are 1989 points in space, and any three of them are not collinear, divide them into 30 groups with different points, and take one point from each of the three different groups as vertices to make a triangle, to make the total number of such triangles the largest, what is the number of points in each group?"

Tang Xiaoya thought for a while, but didn't come up with it, took the manuscript paper and pen from the small bag she carried and calculated, "......" said angrily: "The answer is 51, 52,...... ，56，58，59，…… ，82。 ”

"That's what you're thinking about? A scumbag student like you can't think of an answer for the rest of your life...... Even if you put the answer in front of you, you can't understand it, mentally retarded, brain-dead, two hundred and fifty ......"

After saying that, she glared angrily.

I'll rub it, you can do it if you do it, how can you still make a personal attack, a woman is so vicious.

Although her mouth is poisonous, Liu Sen did not receive any energy, and said in her heart, is this the heart of a knife mouth tofu heart?

"Don't talk so much nonsense, you can get the question. ”

Tang Xiaoya was very disdainful, and said: "It's too difficult, I'm afraid you won't even understand the question, expand the rectangular wave with a width of 1, a height of 2, and a period of 3 into a complex Fourier series." ”

Nima, this topic is not easy to do, fortunately, Liu Sen has completely digested "Advanced Mathematics", this topic can't help him, pondered for a moment and said: "Why don't you calculate a few coefficients, it's too young, your level is at the bottom of the department, right?"

"You make it first and then talk big. Tang Xiaoya was furious.

The boys basically flatter her, how dare anyone hurt her like this, the girl's pride is quite hot.

"Listen, calculate a few coefficients, c0=2/3, cn=[2/nPi]sin(nPi/3), verify that the Dirichlet condition is met, and I won't need to say the rest. ”

Tang Xiaoya snorted heavily, "You come out again." ”

Her gaze softened a little, and she didn't see that this disgusting boy was really at some level.

"Find all positive integers a so that this a can be expressed in at least two ways in the form a=2m+3n......"

She answered it again and said angrily: "Can you only come up with low-end high school competition questions?"

"It's hard to stop you, the junior high school questions are all good topics. ”

After two rounds of fighting, both of them solved it, and the right to come out of the question returned to Liu Sen's hands, he thought about it, this is not good, the girl does have a level, it seems to be a freshman student, and said: "This question is simple, and it proves that f(z)=x+2yi is not parsed everywhere." ”

Tang Xiaoya was stunned, although she had finished learning advanced mathematics, she was not familiar with some parts, she vaguely remembered that this was the preliminary knowledge of complex variable functions, and she had seen similar problems, but she was not very clear.

A quarter of an hour passed, and she still didn't solve it, fine sweat oozed from her forehead, and her fair face was reddened.

A few students in the past didn't know what these two were doing.

Obviously, they all knew Tang Xiaoya, and they were unhappy to see the two of them sitting on a bench, and contributed some energy to Liu Sen.

Intermittently has more than 700 spiritual power.

"If you don't, just give up, don't be ashamed, there will always be a few setbacks in your life, just take setbacks as the driving force for your progress. ”

Liu Sen said very pretendedly, quite like a philosopher.
