My Sister is a Bit Ruthless

  Chapter 51 Punching the Sky into a Hole

   "I'm curious, how did you learn math in junior high school? Why do you owe so much?" Xia Pengfei asked, staring sideways into Si Yu's big eyes.

   "Well, the main energy of junior high school is used to practice sandbags and clean up the gangsters on Wolong Road; I am also obsessed with writing novels, and most of the time I write novels in math class."

  Siyu's pure and beautiful face showed three points of playfulness, and the sudden welfare made Xia Pengfei's thinking and language rhythm slow.

  He was stunned for half a minute before asking: "...novel? What title? When should I go to read it?"

  Siyu honestly said: “It’s a terrible rush, and the data is not good. You don’t want to open the pot and lift the pot.”

  Xia Pengfei went back to the topic, "Do you know why I don’t just fill up high school math for you?"

Si Yu said without hesitation: "You want to solve the problem fundamentally. Mathematics is a subject with strong logic. Junior high school mathematics and high school mathematics are interlinked. Which chain is broken must be repaired first. Proceed to the next link of learning."

  "Clever! Let me talk about my counseling plan first. The explanation of knowledge generally uses a combination of point, line and surface.

The   face is the teaching of all knowledge without any omission, so as not to miss the net, in order to maximize the information; the line is to grasp the main framework, and strive to highlight the backbone of the knowledge; the point is to grasp the key points of the test;

  Any simple knowledge that you understand will be taken at a high speed, and those that are not understood or lacking will be explained in detail; the form of tutoring is a combination of knowledge explanation, practical exercises and commentary. "

  Xia Pengfei explained in an orderly manner, his face was peaceful, and his dark eyes were filled with incomprehensible wisdom and profoundness.

  Serious study and work status will magnify a person’s charm to the extreme.

  Siyu adjusted her eyes and went to see the math textbook that hadn't been opened yet.

  Behind Xia Pengfei and Leng Siyu, Chongchong and Yuanyuan secretly checked their learning status and made sure that the alarm was lifted before returning to the living room to play with the electric toy car that Chongchong brought down.

  Yuanyuan said to Chongchong: "My sister likes to drink tea when she is studying. Go and help my sister make a cup of jasmine tea."

  Chongchong frowned and said, "Yuanyuan, I am a guest, did you forget? Besides, I have never made tea at home."

  Yuanyuan raised her eyebrows and said, "I let you make tea, which is important to you. This shows that you are your own. Do you want me to treat you as your own or an outsider?"

While pressing the remote control and driving the car, the insect smiled and said, "You are a pit, so I won't jump in. Once I say that I want you to treat me as your own person, you won't treat me as a guest. In the end, I was asked to pour tea."

   Yuanyuan grabbed the remote control from the bug's hand, and tried to adjust the direction and speed of the car, but the car was spinning on the ground.

  Chongchong joked: "Yuanyuan, you are not driving a car, you are a spinning top."

  Chongchong expressed dissatisfaction, "Cut, I am new to the road, your old driver is embarrassed to laugh at me."

   "Stupid, let me teach you." The bug stepped forward and taught Yuanyuan hand in hand...

"I'm not very good at collecting and organizing data. For example, for this question, you need to make fan-shaped and bar-shaped charts for several modes of transportation, and compare them. What should I do?" Yu is still learning mathematics.

"Let me tell you the general idea first. The steps of drawing a fan chart; the first step: first calculate the percentage of each mode of transportation in the total number of people, multiply the percentage by 360°, find the central angle of each part, and then Draw a fan shape at the center corner.

  Step 2: Mark the data. The third step: draw a bar graph. It should be noted that the width and narrowness of the straight bars must be the same for the numbers indicated by the horizontal axis and the vertical axis. Here you follow the train of thought I gave. "

Siyu held the pen with thin white fingers that could easily kill people, and calculated the center angle on the workbook according to the ideas suggested by Xia Pengfei; then used the drawing tool to skillfully draw the fan diagram on the workbook, and mark it on the fan diagram. Text and data; later, I used tools to draw the bar graphs and marked them with text data, and wrote a comparison of the two graphs on the workbook.

Looking at the beautiful and neat text, data, graphics and comparative conclusions that Siyu left on the homework, Xia Pengfei found that Siyu’s problem-solving ideas were very clear, and the speed of problem-solving was comparable to the speed of Siyu's long-legged running. The drawing and conclusion are quite accurate.

  Xia Pengfei exclaimed: "It seems that your mathematical talents have delayed sandbags and various fancy activities!"

   Just when the two people's learning progress bar pulled very fast, and the atmosphere of communication was very harmonious, only a loud bang was heard behind them. Siyu and Pengfei quickly turned around, seeing the insects in a daze in panic. On the ground is a broken teacup and a piece of tea.

  Siyu and Pengfei rushed up to check the bugs' hands.

   "Does it hurt?" "Is it hot?" Peng Fei and Si Yu asked.

   Xiao Yuanyuan ran in when she heard the noise, saw the fragments of the teacup on the ground, and went to look at the bug's hand, "Does it hurt the bug?"

  The worm cried and said, "It doesn’t hurt at all, but I was shocked. The tea I helped Sister Yu make was unsteady and fell out."

  Siyu quickly comforted: "It's fine if you are alright, you don't need to pour tea for me in the future, I will do it myself."

  Siyu finished speaking, and rushed out of the room to deal with the endgame left by the bugs. The quickness and high efficiency of his movements made Peng Fei who was on the lookout speechless.

   "How did you develop this speed?"

   "A mile forced out of life."

   "Slow down the rhythm moderately, and life can still continue."

"Someone washes and cooks for you, someone earns money for you, you can naturally go to karaoke, drink coffee, watch movies and play games, of course you can enjoy a slow-paced life; ordinary people's life, you don't understand." Cleaned up the ground and robbed Pengfei for a while.

  Xia Pengfei fell silent when she saw Siyu's emotions.

   "I have learned here today, I will go to work for a while." Leng Siyu started to pack the books and put them in the bookshelf.

  Xia Pengfei was annoyed when he heard that Siyu had to go to work, "Still going to work! Leng Siyu, cohesive, what I said just now was for nothing?"

  Leng Siyu walked up to Pengfei, stared at Pengfei’s charming face, and said genially: “Is the economy with one hand and the culture with the other. What’s not good about balancing it?”

  "You can't go!" Xia Pengfei, who had always been peaceful with Siyu, actually showed the momentum of the boss.

"what?"

   "I said you can't go!" Xia Pengfei emphasized verbatim, with a very strong tone!

"Hey you Xia Pengfei, do you think you can arrange my life if you teach me a little bit? I'll go to make a decision today!" Leng Siyu's eyes widened, and she turned around and led Xiao Yuanyuan to the door. Go, "Bring me the door when you go!"

  Xia Pengfei caught up with Siyu in a few steps, and stood in front of Siyu sisters, and said calmly: "Listen well, I know Aunt Lin's phone number, do you need me to recite it to you?"

   "Do you want to betray me?"

  "Do you dare to step out of this door and try today!"

"Well, you Xia Pengfei dare to threaten me! I hate someone threatening me! Today is the day when the bed is down to block the door of my house, and I will poke a hole in the sky and get out!" Leng Siyu hugged Yuanyuan angrily. , Pushed Xia Pengfei aside, opened the door and went out.

  Boom!

  The security door made a loud noise.

   "Have there been an earthquake?" someone shouted upstairs.

  　Thank you night sky horse, book friend 20191014220023004, new leaf 0000, four sentences a day and other friends for their rewards! mwah!

  　　 Thank you very much for your recommendation votes, comments and support! The queen loves you guys, yeah!
