The subject was changed to this: Xiaohong's brother counted it, and his brother was one more brother than sister, and asked how many more brothers were there than sisters.

The answer to the original question should be three people, but the original question marked Xiaohong as a woman, but it is not indicated here.

Yun thinks about it, it is estimated that many people will directly ignore this point, who stipulates that Xiaohong must be a woman?

Therefore, the correct way to answer this question should be to assume that Xiaohong is a woman and that Xiaohong is a man.

It seems to be a question to be scored, but in fact, there are mines buried everywhere, and after this question, there will be no easy questions.

When Yun Xiangxiang finished solving the problem and entered the calculation problem, a voice sounded: "The teacher has a problem." ”

Yun Xiangxiang couldn't help but look sideways, it turned out to be Du Jing, she ignored it and continued to bury her head in the question.

The invigilator walked up to Du Jing, and Du Jing pointed to the question: "Teacher, is this a man or a woman?" ”

Yun Xiangxiang shook her head slightly, if she wanted to ask, she would definitely ask Xiaohong directly if she was a man or a woman, Du Jing asked, undoubtedly not wanting too many people to know what she asked, and deliberately lowered her voice.

"There's no problem with the title." The teacher returned and walked away.

"How can there be no problem?" Du Jing muttered.

Of course, the teacher won't tell you, it's a hypothesis, and there are two possibilities for answering, but apparently she's got the horns of the bull.

The further you go, the more difficult it becomes, the first of the two problems is okay, but it simply uses the Lagrange multiplier method.

A functional relationship is listed, a range of turnover increases, and a maximum profit is found.

In the last question, Yun Xiangxiang sees a simple question, a simple function graph, and a large blank space, which is the big one.

"Perverted!" After Yun thought about it and calculated it on the draft, he couldn't help but curse in his heart.

I don't know who came up with such a comprehensive question, five small questions, each of which must be counted as a large article.

After that, Yun Xiangxiang had to look for a long time from the scratch paper, doubting life.

Is it too late to check Yun Xiangxiang, the time is just like that, do it first and then look at it, but unfortunately Yun Xiangxiang has just finished it, and has not finished checking the first question, and the time to submit the paper has arrived.

Cover the roll with white paper and leave the exam room.

"Well, think about it, drink some hot water." Yun Xiangxiang came out of the examination room, and Tao Manni and the others had already finished class.

"A large patch of brain cell death." Yun Xiangxiang took a sip of water, "I'm going back to take care of my hair and prevent baldness." ”

"How sure are you?" Ma Linlin asked.

"It's okay in front, I didn't check the last question, and I left it to fate." Yun Xiangxiang shrugged his shoulders, "Hungry, go eat." ”

has already finished the exam, of course Yun Xiang will not bother anymore, he has consumed a lot of brain power, and his stomach is rumbling with hunger.

During lunch, Yang Qi ran over and whispered, "Think about it, my three roommates also want to celebrate your birthday." ”

Yun Xiangxiang followed the direction he came from and saw three teenagers rushing to greet her.

"It's just the three of them, right?" Think about the cloud and ask.

Yang Qi nodded: "I promise it's just the three of them." ”

"Okay, but don't bring expensive gifts, or there won't be a next time." Cloud think about the admonition.

Yang Qi is Song Meng's right-hand man, and many of their activities will bring Yang Qi, a dormitory, if Yun wants to refuse, it will make Yang Qi embarrassed, and it will be nothing to have a meal.

After Yang Qi went back, several people let out a wolf howl, which attracted the attention of other students to speculate.

In the afternoon class, Yun Xiangxiang is still obedient, the results will be announced next Monday, and there are still bonuses and certificates in this intramural competition.

In fact, this intramural competition for freshmen is to select sophomores to participate in the National Mathematics Competition to warm up.

The National College Student Mathematics Competition requires that it must be a sophomore and above, and the top three in the intramural competition will be focused on cultivation in the next year, and it is impossible for Yun Xiangxiang to participate in next year's competition.

This competition is just to prove that his results are not cheating, but it is not that others cannot be questioned at all.

It's that she has only been questioned in the first semester, and there are several semesters in the future, and she can't be pointed at back.

Take advantage of the time now to fight back, lest the rumors become more and more intense.

She will be busier and busier in the future, anyway, her goal is to ensure that the top ten in the department and graduate successfully.

After school, Yun Xiangxiang picked up Yunlin and went to Song's house, followed Yuan Pingqiu to learn opera, without Song Mian, there was an extra fan girl.

Yuan Pingqiu's eldest granddaughter, Yuan Yun, is two years younger than her and is in her second year of high school.

"I thought I was reading early enough, and you were ahead of me." Yuan Wan especially likes Yun Xiangxiang, "I practice with you, better than my grandfather." ”

Maybe it's because of the similar age, Yuan Yun's basic skills are very solid, the two talk and laugh, and they practice faster.

The next day, Yun Xiang wanted to meet his classmates, but he didn't come back to live, so he took Yuan Wan with him.

"Hehe, I'm sorry, I'm sorry." Yun Xiangxiang smiled and pushed the mahjong down.

"Whoever will push me, the blood groove is empty, and if I lose it again, I will eat soil this month." Feng Xiaolu wailed at the men and women playing billiards next to her.

"I'll come, I'll come." Chu Yao came up.

After two laps, Chu Yao and Tao Manni were replaced by Zhu Yuan and Yang Qi, and after three laps, the two of them, including Ma Linlin, a nail household, also left, and Yang Qi's three roommates were replaced.

Don't look at these three people playing mahjong well, but they only lasted five rounds......

Everyone looked at Yun and thought about it with a messy face, because she killed nine of them, and one person won all nine of them!

"Playing mahjong with her is masochism." Song Meng ate potato chips and gloated.

Yun Xiangxiang himself will play mahjong when he is about ten years old, and Hua Xiangrong is even more obsessed with this, and the two-in-one is absolutely invincible.

"It's just hell, she can touch anything she wants, and finally stuck her once, I drew my own cards, and I was so excited that I hit my hand and threw it out......"

The rules of the mahjong table, leaving the hand is to play the cards, just like the cloud wants to eat the bar, and then the bar on the flower.

Zhu Yuan succeeded and dragged Yang Qi and Ma Linlin into the water.

"Hahahaha, eat more in a while, and eat back what you lose." Yun Xiang happily counted the money.

They played for twenty yuan, with a cap of 200, and she won more than 10,000, and an average of more than 1,000 per person lost to her.

"This world is fantastic, I thought in my heart that I would fight 60,000, and the devil knows how I would become 50,000 if I continued to fight......"

Yang Qi's roommate Yang Ao thought of the last one, and he actually put a big pair for Yun to think about, and he was a little unable to come back to his senses.

"The dragon seven pair can touch themselves, what else can we say?" Tamani looked loveless.

"I lost 2,000 yuan, and I worked in vain during the winter vacation, and I will never play mahjong with Yun Xiang in the future." Feng Xiaolu pretended to cry.

"I finally understand why Sichuan Province calls this style of play a river of blood!" Chu Yao realized with a painful face.
