Near the morning, the mobile phone alarm did not ring, Jiang Wen did not wake up, but fortunately, a light rain outside the house woke him up, but he was still ten minutes later than before.

When I woke up, I realized that I forgot to charge my phone last night.

I was looking forward to the character materials collected by his master, but unfortunately the screen was black and I couldn't see it.

In recent years, the mobile phone has been in trouble here, once the power is out of power and turned off, it will take many minutes to connect the charging cable before the screen is turned on.

Now I'm in a hurry to go to school and I don't have a power bank on my body, so I can only put my phone at home to charge it and come back at night to see it.

When I arrived at the classroom, the atmosphere was obviously different from the previous depressing, the morning reading was canceled, and many people stared at "May Three", "Study Guide", and "Wrong Problem Collection...... Tossing and turning anxiety.

Jiang Wen then remembered that he had taken the exam in the early month.

The first monthly exam is quite important, after all, it is related to the mood and pocket money before the next monthly exam, and the school will cancel the morning reading a week before the monthly exam, so that everyone can check and fill in the gaps in stages.

But this is not a good intention, this is just to give those who use the excuse of "there are too many classes arranged by the school and there is no time to review", a sober understanding.

People are not afraid of not learning well, but they are afraid that they really can't learn well, and they will deceive themselves because they don't have enough time.

Jiang Wen also agrees with this.

He also planned to go back to his seat and flip through the book. When Shen Yan saw him coming, he raised his head suddenly, as if he saw his prey!!

Jiang Wen guessed that Shen Yan was going to talk to him about yesterday's observation of the battle situation.

But Shen Yan couldn't let go of her hand, she was being asked questions by the representatives of the mathematics department in the class.

Mathematics representative - Su Qian, Jiang Wen knew, a junior high school before, was a girl who studied hard but couldn't get in, and she would be depressed for a long time when she took the exam.

"Shen Yan, can you tell me about this inequality?"

Su Qian was actually going to ask the math teacher, but during the period before the monthly exam, the math teacher was surrounded by water.

It's not that Su Qian didn't think to ask other people.

But she felt that the people in the class were so strange, her high school classmates were no longer as simple as they were in junior high school, and some people understood the questions she didn't understand, but they didn't talk about it seriously, or if they did, they would only talk about the question and choose A, and they wouldn't tell the essence.

Rolls, not out of the society, just papers, from school.

So Su Qian planned to ask Shen Yan.

From the contact with Shen Yan in the past few days, Su Qian felt that the latter was not a high-ranking scholar.

And she was right.

Shen Yan took out the draft book and prepared the calculation steps seriously: "Which way?" ”

Shen Yan didn't think that the question-making skills were confidential things, skills? High school adds up to just a few pages of A4 paper.

What really determines the score is whether you can use skills proficiently, and that is related to personal ability and experience.

"This and this." Su Qian pointed to the question——

Solution inequality: (x2-9x+11)/(x2-2x+1) is greater than or equal to 7

Shen Yan glanced at it and replied directly: "X is greater than or equal to -1/2, X is less than 4/3, and x is not equal to 1." ”

Su Qian: "......"

Jiang Wen: "......"

Turtle tortoise? The calculation is so fast! What about the steps?

But Su Qian could see that Shen Yan was not hiding and not writing, but the calculus was too skipping.

Just like a primary school student encountering the 8x9 calculation problem, he has to get one by one, and one or two gets two, and slowly memorize it along the ninety-nine multiplication table.

And junior high school students know at a glance: 8x9=72.

"Can I ask for the next steps?"

"Cauchy inequality." Shen Yan took a Cauchy inequality seriously and directly calculated the value of x.

Jiang Wen caught a glimpse on the side, a little unsure of what to say: "......"

…… Cauchy inequality is out of class!!

Su Qian couldn't understand it directly: "......"

Turtle ...... What is Cauchy's inequality!

As a scumbag, Su Qian smiled bitterly, she gave up, and stumbled back: "Thank you...... Xie Shenyan. ”

It's not that the top students don't want to teach.

However, the top student can't take it.

Su Qian planned to leave to realize on his own, but when he left, he noticed Jiang Wen, as if he had seen a savior, and his eyes lit up!

Jiang Wen couldn't stand it anymore: "......"

"I'll tell you." It's a junior high school classmate.

Then write the steps slowly——

(x2-9x+11)/(x2-2x+1) is greater than or equal to 7

Equivalent to: (x2-9x+11) is greater than or equal to (7x2-14x+7), note: x is not equal to 1

Equivalent: 6x2-5x-4 is less than or equal to 0

The solution is: x is greater than or equal to -1/2, x is less than or equal to 3/4, and x is not equal to 1.

Jiang Wen wrote one by one, and there were traces of steps to follow, and finally explained to Su Qian.

Su Qian looked excited, and returned to the table with a full harvest: "Ah! Got it, got it! Thank you bro!! ”

"You're welcome." Jiang Wen felt that it was nothing.

After Su Qian left.

Shen Yan's eyes were subtle, and he asked, "Isn't your solution too basic?" ”

Jiang Wen was about to speak, but Shen Yan said again: "Who is a serious person who uses this solution?" ”

Jiang Wen: "......"

Day, serious people understand it like this, okay!

But Shen Yan didn't ask much, after all, there were serious things.

She faced Jiang Wen and decisively threw out the topic: "There are too many daily life, I can't count them for a while, so I have to wait." At present, there are only a few photos, taken yesterday, you can take a look, it should be helpful for you to describe the appearance of the heroine. ”

Jiang Wen knew that he couldn't escape this, so he spoke quietly and firmly: "It's not appropriate to do this, it's not good to take pictures secretly!" ”

But Shen Yan had already started to touch his phone.

Jiang Wen couldn't stop her from taking her phone, but she had already made a decision in her heart-

When Shen Yan puts out the photo, she must not be able to look at it, and then solemnly tell her that this behavior is wrong!!

However, as soon as he thought so, Shen Yan quietly whispered to Jiang Wen's ear: "She was still drinking yesterday, it must be difficult to see this kind of look." ”

“！”

Surprise! Shen Bingyan's woman still drinks in private?

"Really, yesterday my sister and girlfriend came, and the two of them ate peanuts together, ate melon seeds, and got very drunk." Shen Yan said very seriously.

“！” Jiang Wen.

Surprise! Unexpected!

"Do you want to see it?" Shen Yan had already spread the phone in his hand.

"Goo~" Jiang Wen muttered deeply, unable to distinguish his opinion on this matter.

Although he knew that his master was also collecting materials for him to set up a rich woman and a royal sister, the distant water could not save the near fire.

Facing the material in front of me, I couldn't bear it at the bottom of my heart!

But...... But!

It's a curse to read a girl's composition.

Now look at the photos of private life......

This?

Is this a punishment?

Looking at Jiang Wen's embarrassed expression, Shen Yan rolled his eyes, as if he had found a breakthrough, "I'll send you a penguin message with the photo." ”

"I didn't have my phone with me." Jiang Wen seemed to welcome and refuse, to be honest, I wanted to see it.

Shen Yan was stunned for a moment, gritted his teeth, and made some kind of decision, "The photo is in the phone, there is no password, you return the phone to me after reading it!" ”

Jiang Wen wanted to excuse himself.

But Shen Yan couldn't refuse to put the phone in his drawer.

And he really didn't want to refuse.

“……”

So, Jiang Wen touched his phone.

fell silent.
