Chapter 5 Math is Fun

"Qianqian, looking at your grades in other subjects, it shows that you have a strong learning ability. As long as you use this energy in mathematics, you will definitely get ideal results if you persevere."

Tong Fei also talked about a few examples of the students he had supervised, whose grades improved by leaps and bounds, which was naturally somewhat exaggerated.After listening to it, Yao Qianqian's confidence increased a bit.

"Okay, teacher, let's start class then."

Seeing that Yao Qianqian's condition had adjusted, Tong Fei started his lecture.

"Let's talk about the wrong questions on your paper first. Like question 6 of the multiple-choice questions on this paper, you can use the special value method to do it. You can choose the correct answer by substituting a few values ​​of x."

"Well, let me try it."

One minute later, Yao Qianqian said excitedly, "Wow, really, I didn't expect it to be so simple."

"Well, mathematics is actually not that difficult. Most of the time, the correct method is not found. Then question 9, according to the nature of the arithmetic sequence, all the items are represented by a7, and it comes out all at once."

"There is still this nature, let me write it down." Yao Qianqian carefully wrote down the formula Tong Fei said with a red pen.

"The first question of the big question, the question of the sequence, when calculating the sum of the first n terms of the geometric sequence, did not consider the case where q is equal to 1. Three points were deducted. It's a pity."

"Yeah, I forgot this." Yao Qianqian smiled embarrassedly.

"Second question, the typical difference is the sum of the first n terms of the sequence, and the dislocation subtraction method will be subtracted."

"Mismatched subtraction method? I seem to have heard of it. Teacher, please tell me, what exactly is it?"

"Well, let me draw it for you."

On the straw paper, Tong Fei listed the practice of dislocation subtraction.

Seeing Tong Fei's way of solving problems, Yao Qianqian felt for the first time that mathematics had become interesting.

Tong Fei's side profile is very eye-catching, coupled with his serious look when solving the problem, Yao Qianqian couldn't help staring at Tong Fei.

"Okay, I'm done writing, let me tell you something."

Yao Qianqian looked at Tong Fei's problem-solving process.Although Tong Fei's handwriting is not very beautiful, the whole process is simple and clear, with clear thinking, and it looks pleasing to the eye.

For the first time, Yao Qianqian felt that mathematics had an artistic beauty.

"The most important thing about the misplaced subtraction method is that you need to write out the sum of the two series with the wrong digit after expansion, and then subtract them up and down." Tong Fei explained carefully, pointing at his problem-solving process.

Tong Fei's explanation seemed unremarkable, but it seemed to have a kind of magical power. After listening to it, Yao Qianqian completely understood it.

"As long as you have mastered several common methods in the sequence part, you can easily get 12 points for the first big question."

"Well, teacher, it's the first time I feel that the big math problem is so simple. Let's continue."

Before you know it, an hour and a half is coming.

Ren Dan waited restlessly in the living room, and from time to time put his ears to the door, wanting to hear something.

When he first met Tong Fei, Ren Dan didn't have much hope in his heart.She didn't dare to tell Tong Fei that none of the teachers who taught Yao Qianqian lasted more than an hour, and Yao Qianqian asked them to leave get out of class early.There was even one time when Yao Qianqian saw the teacher for the first time and felt that it was not pleasing to the eye, so she just gave him money and sent him away.

This time, it has been an hour and a half, and there is still no movement. Could it be done?Ren Dan was a little dubious.

"Qianqian, it's almost time, let's stop today." Tong Fei looked at the time and said to Yao Qianqian.

"Well, good teacher, I learned a lot today, and I enjoyed your class." Yao Qianqian replied with satisfaction.

Seeing Yao Qianqian's expression when he came out, Ren Dan finally had a bottom line in his heart.

"Teacher, see you next week!" Yao Qianqian waved at Tong Fei and sent him out.

"See you next week!" Tong Fei said goodbye to Ren Dan and Yao Qianqian with a smile.

Hearing her daughter's words, Yao Dan was both happy and puzzled, how did Tong Fei make Qianqian make such a big change.

"It looks like it shouldn't be a big problem." After going downstairs, Tong Fei finally breathed a sigh of relief.

When he got home, he turned on his phone, and Tong Fei saw the message from Ren Dan.

"Teacher Tong, thank you. Qianqian is very satisfied with you. From now on, I will have class at this time every week (smiley face)."

"Okay, sister, I hope that with our efforts, Qianqian can skyrocket in math."

Ren Dan transferred 500 yuan directly, and Tong Fei clicked to receive it.

Tong Fei doesn't have much feeling for money, but Tong Fei cares more about being able to satisfy the child and improve the child's grades through his own efforts.

At this moment, Tong Fei felt a sense of accomplishment and a sense of mission in his heart.In Yao Qianqian's senior year of high school, her grades must be improved.

At this time, Tong Fei heard the voice of the system. "The task has been completed, please receive the reward."

Tong Fei opened the system interface, received the system reward, and directly added attribute points to vitality.

Since his vitality value increased, Tong Fei felt that he was more motivated to do anything than before, and his life suddenly became more fulfilling.

What to do this weekend?

Thinking about this, the sound of the system appeared again.

"System tasks have been updated."

"Exactly, let's see what tasks the system has released."

[Task 2: Get rid of system dependence.Increase a little attribute value through your own efforts.Mission reward: 5 attribute points, [-] skill points, a random skill pack]

[Task 2: Say goodbye to boring parties.Express yourself in the company team building and get applause from the audience.Mission reward: 4 attribute points, [-] skill points]

Looking at the tasks issued by the system, Tong Fei thought about it.

The first task is to improve one's own attributes without relying on the system.Tong Fei looked at the 4 attributes in the system, thinking which attribute was easier to improve.

First of all, the attribute of wisdom. If you want to improve your wisdom, you need to read more good books and deal with smart people.Obviously, it is not easy to improve in a short period of time.

Secondly, the attribute of vitality, how to improve vitality?It seems that there is no good way.

As for appearance, you can't go for plastic surgery.

Thinking about it this way, it is still easier to increase strength.

The system released this task probably because it doesn't want to make itself too dependent on the system, Tong Fei thought.

The second task is to express yourself in the company team building.Thinking of the team building before, most of the people, including Tong Fei, ate something casually, played with their mobile phones, and waited for the leaders to play enough before going home.

Not only is it boring, but it doesn't allow you to ask for leave.

There are also performances in the middle, but Tong Fei usually hides in a corner, waiting for the end of the party.

"It's time to make some changes. But how to express it? You can't perform a math problem, right?"

Tong Fei was thinking while walking in the room, and saw the dusty guitar beside the bed.After wiping it with a rag, he took out the tuner to adjust the pitch, and Tong Fei played and sang by himself.

Since he hasn't touched the guitar for a long time, Tong Fei's performance is a bit rusty, and his singing is not as steady as when he was in college.

"This level is still not enough." Tong Fei opened the skill interface in the system.

After adding all the remaining skill points to music, Tong Fei's music skills became 9/100 (beginner).

Although I haven't reached proficiency yet, the change is very obvious when I play and sing again.Whether it is playing or voice, there has been a qualitative leap from before.

Thinking of the team building next weekend, Tong Fei thought about completing the first task as soon as possible to get more skill points.
