Boys should take good care of themselves [entertainment circle]

"I need to find a way to take out the small book, or write down the words on it..."

When he was thinking, Qin Zhenlu suddenly hit the small book on the ground with a clothes rail, and then slowly scraped it towards the door.

Su Mengyu watched his movements and frowned slightly: "No way, the door is too narrow, and the notebook can't get out."

"It doesn't matter, we just need to take off the side with writing on it."

When Xiaoben was at the door, it really got stuck in the crack of the door. Qin Zhenlu then shifted the direction of the clothes drying pole, poked towards the fallen knife and tape, and then slowly scraped them out.

Su Mengyu immediately understood what he wanted to do, and couldn't help shaking his arm: "My God, why are you so smart, do you really not consider coming to our school to study as a graduate student?"

Qin Zhenlu was caught by him and shook his body. He was very helpless at Su Mengyu's blatant digging behavior. He kept moving his hands, and neatly wrapped the knife around the clothes rail, then pulled the blade out, and again Stretched in through the window.

The blade of the knife is very sharp, with a light stroke on the paper, the written side will be separated from the small book, and then it can easily pass through the crack of the door.

[6666, I give full marks for this operation]

[Hahahahaha, Xiaoyu finally couldn't help but start digging corners?]

[I remember that Xiaoyu was the number one student in science in the college entrance examination in province A, right?Brother Lu seems to be recommended directly to the Beijing Academy of Drama, and he didn't even take the art test]

[If Qin Zhenlu didn't go to act, but took the college entrance examination according to the rules, would it be possible for Qin Zhenlu to become Xiaoyu's graduate student? 】

[Why do you have to be admitted to Q University?My big B expressed dissatisfaction! 】

[As a big wet brother who is about to be driven crazy by the experiment, my Professor Lu said that he is very interested in the deer actor (head and hands) (smile)]

[? ? ?The one in front, are you the big wet brother in Weibo last time? 】

【That’s right, it’s me (smile bitterly)】

[Aren't you going to continue the experiment?Why did you come to watch the live broadcast? 】

[I was caught by the professor when I was fishing, and now he is watching with me beside me, by the way, let me help dig people QAQ]

【? ? ? ? ? 】

【He also said, if my hand was half as stable as Brother Lu, I wouldn’t be doing slices now QAQ】

【...If you don't act well, you will go to the graduate school entrance examination. It's amazing, my brother Lu】

Su Mengyu had already picked up the piece of paper on the ground, which contained several paragraphs of text and a math problem.

[Today, I saw a question on the test paper of my son who is in the first grade of elementary school. He said that he was the only one in the class who did it. He is really proud of me!

Thanks to the champion brand yogurt that I feed him every day, he can grow so smart!To be a champion, to be a champion, little Einstein is not a dream!

I want to set the answer to this question as the password of the student file room, this time to commemorate this special question!

Known: ABCD×9=DCBA

Also, the same letter represents the same number, and different letters represent different numbers.

May I ask: DCBA-ABCD=? ]

"Champion brand yogurt under Hao Drinking Group?" Wai Zai was successfully attracted by something with a strange style of painting inside, "What is this, a sponsor?"

"Come here, come here, this is my party, none of you are allowed to grab it from me!" Xuan Zi'an jumped up and down in front of everyone like jumping candy, then suddenly squatted down and rolled up his trouser legs.

On the white and smooth calf, there are dense black Chinese characters, which may be due to the complicated structure of the characters, among which the huge word "Hao Drinking" is very eye-catching.

"I'll go," Waizai looked at him with the eyes of the second idiot, "you wrote the oral broadcast on your legs? Why didn't you write it on your arms?"

Xuan Zian tried his best to move his legs, Hanhan smiled: "Hehe, the area of ​​the arms is too small."

The corner of Su Mengyu's mouth twitched, and finally couldn't help saying: "...Are you a tease sent by the monkey?"

So, under everyone's loving eyes and the barrage of "hahaha" on the screen, Xuan Zi'an successfully completed his oral broadcasting task.

"Products produced by Hao Drinking Group must produce high-quality goods! Drinking champions, becoming champions, little Einstein is not a dream!"

"Okay, well said," Su Mengyu clapped his palms twice without emotion, then bowed his head together with everyone, and continued to look at the topic on the paper.

"It is known that ABCD multiplied by 9 is equal to DCBA, the same letter represents the same number, and different letters represent different numbers, then A must be 1, D must be 9, and then look at the hundreds... eight/nine 72... Finally, find DCBA minus ABCD... ..."

Su Mengyu hugged her arms in front of her chest, gently rubbing her chin with her right hand, while Qin Zhenlu put her hands in her trouser pockets, tapped her right hand fingers in the pockets regularly, and then at almost the same moment, the two straightened up and made gestures towards each other. Go to the student archives.

Su Mengyu looked at him with raised eyebrows, Qin Zhenlu smiled and shook his head: "The password is 8712."

"Coincidentally, that's what I calculated." Su Mengyu smiled at Qin Zhenlu, her beautiful eyes curled up, and then reached out and pressed a few numbers on the combination lock.

The blue screen flickered a few times, and a green prompt appeared in the next second.

[Verification succeeded]

"OK, the door is open." Su Mengyu lightly held the doorknob, turned her head to signal to everyone to enter the door.

【That's it?That's it?Can it be faster? ? ? 】

[Reading questions is equal to solving questions 666]

[This speed is outrageous]

[Even though it’s the Nth time, I still can’t adapt to this speed, it’s really fast and powerful~]

[You can drive on this broken road, awesome]

[Waiting quietly for brother Zi'an's question, please come to a cram school for elementary school students, crab]

Seeing that Waizai and You Changyi also reacted one after another, the scumbag Xuan Zian was crying, so he had no choice but to follow the barrage wish and raise doubts.

"Let's go into the room first, go in and sit down." Su Mengyu pushed open the door and turned on the light. This is a relatively narrow room. In the center of the room are three tall bookcases, similar to those in a library, neatly arranged inside. File information of previous students.

Su Mengyu was not in a hurry to find clues, but walked to the desk, pulled a chair and sat down, stretched out a hand to Xuan Zi'an, Xuan Zi'an immediately took out the phone book he was carrying with him, and tore off a piece of paper. paper, took out a pen from his pocket, and handed it over together.

The poor phone book has been torn countless times since it left the sporting goods room, and now only a thin cover remains.

Xuan Zian also found out about this, he decisively tore off the sides with the phone number on it, folded it and stuffed it into his pocket, and then threw away the remaining empty shell.

It doesn't matter, the phone book has been torn out, so there is still an accounting book.

Bookkeeping: shivering.gif

"A four-digit number multiplied by 9 is still a four-digit number, so its first digit must be 1, so A is equal to 1."

Su Mengyu wrote the formula in vertical form, turned the paper to Xuan Zi'an's direction, and at the same time moved his wrist slightly, marking a "1" next to "A", so the vertical form became " 1BCD×9=DCB1”.

"Look at the known formula first." Su Mengyu tapped the position of "D" with the tip of his pen, "The ones digit obtained by multiplying D by 9 is 1, and ninety-nine is 81, so D is equal to 9, and then we determine the hundreds digit, because The hundreds place does not carry to the thousands place when multiplying by 9, so the hundreds place must be 0."

After all, "9" and "0" have been marked next to "D" and "B", and the three letters have been calculated in the blink of an eye.

Xuan Zi'an stared at the three numbers that suddenly appeared, and scratched his head in pain: "But, how do you know that the digits of hundreds have not been rounded up to thousands?

"Because it has been determined that D is equal to 9, the thousands digit of DCBA is 9. If the hundreds digit is entered into the thousands digit, the final result will be five digits instead of four digits, so the hundreds digit of ABCD can only be 1 or 0, A is already equal to 1, so 1 is excluded, and B can only be 0, so now the three letters A, B, and D represent the numbers 1, 0, and 9 respectively, and the last number is left to you."

Su Mengyu stood up and stuffed the pen and paper into Xuan Zian's hands, then pressed his shoulders and let him sit on the chair.

Xuan Zi'an, who was suddenly surrounded by a group of academic masters doing the questions: "..."

Wai Zai pinched his shoulders and cheered up: "Come on, An'an, you can do it!"

Xuan Zi'an: "..."

The hand holding the pen trembled slightly.

[Hahahahaha, brother Zi'an is so cute, he is really a scumbag]

【Anyway, he's an idol, can he be promising? Isn't it just a math problem?Neither will I (funny)]

【Ahhh, I figured it out!I am faster than brother Zi'an! (pride)】

[I wanted to get rid of the idiot characters in the last show, but who knows that they are gone forever on the road of idiots (dog head)]

[Question: The agent's psychological shadow area]

[Sister Chen: Forget it, as long as you are happy, I wish you a long smile and a long life (smile)]

[Hahahahaha typo xswl in front of it]

Xuan Zi'an's eyes trembled, he clenched the pen in his hand, and then began to... exhaustively with shaking hands.

"If C is 0... oh no, B is already 0, A is 1, then 0 and 1 will not work, if C is 2, two 98, 8 plus 8 is equal to 6, but B is 0 and not 6, So C is not 2, if C is 3, three nines 27, 7 plus 8 equals 15, B is not 5, so 3 is not, if C is 4..."

Everyone: "..."

[Hahahahaha why the hell am I reading this while doing my homework, my mind is full of ninety-nine multiplication tables, I feel like I'm back in elementary school]

[My IQ was not very high before, but now my IQ is getting lower and lower (funny)]

[Weakly ask, isn't it the way to ask for it in the end? 】

[I was doing the same thing as Xuan Zi'an and silently put down the pen in my hand]

[Students: I thought the result was already obvious, but I didn't expect...]

[Hurry up and stop him personally!This TM has to be raised to 8 to end! 】
