In a sense, human civilization began with knotted rope records, which were one of the few means by which our ancestors were able to record facts and disseminate information without the limitations of time and space in ancient times, and this kind of knowledge can also be largely classified as arithmetic. In ancient times, people regarded arithmetic as a science that could peek into heaven and fate, and fortune-telling also came from this.

In modern society, thanks to the popularization and development of schools, the development of people's wisdom has reached an unprecedented level, arithmetic is no longer mysterious in the eyes of people, as far as the general public is concerned, few people believe that it can peep into the heavens, let alone associate it with fortune-telling, but it is still one of the indispensable basic disciplines to promote the progress of human civilization, and it is the foundation that must be mastered in all fields of life if you want to make achievements......

In short, if you want to learn finance well, mathematics is absolutely unavoidable, and if you can't learn this, there is no way to take the next professional classes.

"So why did you just talk so much, don't you just say the last sentence?"

Duan Jingyu, who stayed up late last night chasing dramas and was still chasing dramas at noon, rolled his eyes at Xiao Wu on the table, and said listlessly.

Xiao Wu lowered his head and played with his mobile phone while saying casually: "If I don't say that, can you understand the great significance of mathematics?" ”

"I understand, the great significance of mathematics is that you are more powerful, huh, shallow?" Duan Jingyu turned her head to look at Jiang Qianyu, seeking the support of public opinion, she was lying on the table, her head leaned forward very much, and she was not worried about being blocked by Xiao Wu.

"Don't ask me, I'm not available, I don't know anything."

Under normal circumstances, the four-person group in the 205 dormitory came to class relatively early, and now there are nearly twenty minutes before the first class in the afternoon, and there are not many people in the big ladder classrooms of the three classes, Jiang Qianyu is previewing the content to be talked about in this class, as long as time permits, she generally maintains this good study habit.

She was reading a book, and Yao Shushu, who was sitting next to her, was looking at her, looking up and down, and then leaned over and whispered, "How many catties are you now?" ”

"Ninety-six, I've always had a stable weight." Jiang Qianyu still didn't raise his head.

"Ahh Yao Shushu looked very aggrieved, "I secretly weighed myself at noon, and found that I had gained another pound, and now I am almost one hundred and twelve, and I am so much shorter than you." ”

"Then you eat less sweet oil, yesterday I told you not to eat it, but you didn't listen."

"No, let me not eat I'd rather gain weight."

"Then you deserve it, let you accompany me to the gym and not go."

"It's too ugly, I'm embarrassed to go, if I'm as beautiful as you and have such a good body, I'll be in the gym every day."

Jiang Qianyu rolled his eyes and didn't bother to speak again.

"If I had known that finance would have to study high mathematics, I wouldn't have reported this broken major if I was killed, do you know what beliefs I relied on to support my high school? It's just that you don't need to study mathematics in college......" I have long said that I want to make up for sleep before class, so that everyone should not quarrel with her Duan Jingyu is still complaining to Xiao Wu, while still holding a small mirror to look at a few freckles on her cheeks, she is not as fat as Yao Shushu, but her skin is not very good, but the other three people in the dormitory, not to mention Qianqian and Xiao Wu, even the chubby Yao Shushu has better skin than her, I don't know how much.

"Then why did you apply for our major in the first place?"

"It looks amazing, and no one has told me that I want to study math again, and it's almost the end of the semester, and I feel like I'm going to die ugly......"

"You learn from shallow, chase less dramas and read more books."

"I'd rather go to the gym than watch math...... English is pretty much the same. ”

……

The four girls were doing their own thing, chatting from time to time, and the number of people in the large lecture hall gradually increased, and some of them were in the same class or familiar with them, and they would say hello, or sit down near them, there were boys and girls, but there were fewer boys who would sit closer.

"Hey, why didn't Shen Gonghai come over today? Didn't he want to chase you some time ago? ”

A handsome and upright boy held a book, and after walking to the last row with the two boys in the same dormitory and sitting down, Xiao Wu asked Jiang Qianyu a little strangely, and Duan Jingyu and Yao Shushu next to him also came over when they heard the words.

"Maybe it's because the last time he called me, it was a guy who answered."

Jiang Qianyu said casually, but Xiao Wu and the three of them all widened their eyes all at once, and asked almost at the same time: "Who?" Who? When? ”

"On New Year's Eve, Lin Xuan picked it up."

"Hush."

"Your brother?"

The three girls who were originally gossiping suddenly lost interest, and Xiao Wu said a little strangely: "Shen Gonghai didn't hear it? ”

"I don't know, it's possible, he doesn't play games."

Duan Jingyu asked, "Don't you explain?" In fact, Shen Gonghai is quite good, and he is also handsome. ”

"There's nothing to explain."

Jiang Qianyu rolled his eyes, closed the book, took his mobile phone to look at the time, and by the way, he looked to see if there was any news, but there was no unread news, but there was nothing he wanted to read, so he put down his mobile phone again and continued to read.

When the large classroom was basically full of people, the old professor walked up to the podium with a cloth bag and began this afternoon's lecture.

Basically, any school has students who work hard and those who don't, the difference is in the proportion, Jiangnan University of Commerce has a good school spirit, and the Department of Finance is one of the two ace majors in the school, and the quality of students is generally good, even Duan Jingyu, who hates mathematics the most, listens to lectures very hard.

After the first class and break, the old professor went to get the hot water with the finished water cup, and the students also went in and out one after another, solving their own things.

Jiang Qianyu refused Xiao Wu and Duan Jingyu's invitation to go to the toilet together, took his mobile phone and turned on the live broadcast, seeing that the match between AVI and ASF had reached the end, and the highlands had already broken the two roads, it seemed that it was going to end soon, so he turned off the sound, and then played the live broadcast, took Yao Shushu's glasses case, put the mobile phone inside, and blocked the front with his bag.

"What are you seeing?"

Yao Shushu leaned over and looked at it, "Wait a minute, your brother has a game?" ”

Jiang Qianyu said "um", "The next game should be soon, this game is about to end." ”

"Okay."

Yao Shushu pursed his lips, "I don't understand, your brother's game is not his boyfriend, why do you have to watch every game?" ”

"I like to watch games, can't I."

"Then don't always look at your brother."

"That's different."

Xiao Wu and Duan Jingyu came back soon, and the first thing Xiao Wu said when he sat down was: "Brother-in-law's game is about to start?" ”

Jiang Qianyu held his chin and nodded, ASF's two C positions were killed, this game is over, and the next thing is the sky fighting fish dragon team, I don't know if I can win.

Duan Jingyu also stretched his neck to take a look, and then he was not interested in watching it, "You can't change anything if you see it, why do you have to watch the live broadcast, just watch the replay later." ”

"That's different."

"What's the difference?"

"It's the same as when you go to a concert or look at the screen, you can't see where people are without a telescope, why do you spend so much money and go to the scene?"

Yao Shushu nodded and said, "It seems to make some sense." ”

Duan Jingyu said: "There is a truth to Mao." Turning his head to stare at Jiang Qianyu, "I seriously suspect that you have a brotherly control tendency." ”

Jiang Qianyu rolled his eyes and ignored her, Duan Jingyu said again: "Actually, speaking of which, your brother is really good, you see, he is tall, handsome, and then he is good at playing games, he can cook, and he is a professional player, and he can continue to go to school at Western University after retiring...... If I hadn't been good-looking, I'd have done it. ”

Yao Shushu said with a smile: "Xiao Wu can go and try it, you are the best looking in our dormitory except for shallow." ”

Xiao Wu said angrily: "I have a boyfriend." ”

"Didn't you say you broke up last time?"

"It's okay to reconcile again."

Jiang Qianyu smiled: "It's okay, he doesn't like you if you don't reconcile." ”

"Yes, yes." Xiao Wu rolled his eyes and made a very disgusted expression, "With such a beautiful sister as you dangling in front of you all day long, how can you look at me and other vulgar fans." ”

Although Jiang Qianyu does not live in the dormitory, among the four people, Xiao Wu is the closest to her, this kind of joke will naturally not be taken to heart, Duan Jingyu has no joke expression just now, among the four people in the dormitory, she is easier to calculate, Xiao Wu and Jiang Qianyu also knew that it was their joke just now that made her unhappy, so they moved away from the topic and turned to discuss the game.

The dormitory relationship in the university is the closest and most complicated, especially the women's dormitory, some stumbles are inevitable, but there are no major grievances, timely adjustment will not cause any major contradictions, and the relationship between the four people in the dormitory has always been good, Duan Jingyu secretly competed for a while, and listened carefully after class.

Jiang Qianyu only listened to the class for a while, then took out the delicate and small charging case from the bag, and then took out one of the two small independent Bluetooth headphones placed inside, pretended to pick up something, and secretly stuffed it into his ears, and then combed his long black and smooth hair, covering the headphones, and then sat up straight again, listening to the lecture and listening to the live broadcast with one ear.

The headphones were soon automatically connected, and she turned up the volume of the live broadcast a little, listening to the commentators discussing the next two teams.

Sky and the Ichthyosaurus team belong to one family, and now they are independent, each of them has a lot of popularity and attention, in fact, both in terms of strength and popularity, the Ichthyosaurus team is better, but the commentary naturally won't say that.

"sky was able to reach the quarterfinals of this Demacia Cup, in fact, it eliminated two LPL teams, and all of them were 2:0, so everyone must not despise them because they just returned to the LPL this year, if there are viewers who watch the qualifiers, they should have a certain degree of understanding of their strength."

"Yes, and from the player's point of view, Sky is also not weak, the first thing I have to say is that they are on the road, the brother-in-law is an emergency substitute in this year's World Finals, and the performance can be said to be extremely amazing, I think this description is not too much."

"It's certainly not too much, they doubled up against this year's World Finals champion Crane, a quadruple champion."

Jiang Qianyu listened to the words of the commentators coming from the headphones, the corners of her mouth couldn't help showing a sweet smile, and the little five next to her glanced at her, a little strange, and then glanced at the live picture playing on the mobile phone, pouted, and then continued to listen to the class.

"The other player on the lower road, to be honest, is more amazing than seeing my brother-in-law...... Haha, I think many viewers should feel the same way as me, of course, everyone must not ignore Xiaoxue's strength just because she is beautiful, she is a player with very strong personal strength, and I have always been looking forward to the collision between her and Xiyan, after all, they are all beauties, and they are all very powerful ADC players. ”

"Xiaoxue has changed to support this season."

"I know, but it's hard to say now, because they have swapped positions on the lower road, including when the brother-in-law was still in the auxiliary position, and Xiaoxue was in the AD position, they had swapped positions...... Of course, this is not a violation, because the players are still unchanged, so it can be said that it is a tactical adjustment. ”

"Now that our players are in place and the crowd has given a very enthusiastic cheer, it's up to them to see who can win this match, the winner will advance directly to the next round, and the loser will go to the lower bracket, and then there will be another BO3, also today."
