Chapter 21: Where's My Breakfast?

Liu Zifei seemed to have suddenly opened her mind, and she actually took the initiative to ask Geng Wan'er about math problems during recess.

"Wan, goddess, I have something to look for you. Liu Zifei didn't have the first panic.

"Liu Zifei, don't call me that. ”

"Wan'er, I have a question for you. ”

"What's the problem?"

"Can you help me with a math problem?" Liu Zifei's eyes were sincere, not like she was talking to her at all.

"Yes. Since it is a topic, Geng Wan'er is naturally generous.

"Wan'er, look. Liu Zifei put the math problem on Geng Wan'er's desk.

"Hmm...... I don't really understand this question. Geng Wan'er replied truthfully. It's not that she doesn't want to answer Liu Zifei's question, but she really won't.

"Wait a minute. ”

Geng Wan'er walked towards Tong Hao with Liu Zifei's book.

Liu Zifei finally mustered up the courage to ask Geng Wan'er the question, and in less than a minute, Geng Wan'er went to find Tong Hao.

Tong Hao looked helpless, you can't blame me, you gave her to me.

Liu Zifei asked Geng Wan'er a statistical problem, although most of it can be solved by using permutations and combinations, but the latter part uses functions, which is why Geng Wan'er can't solve it.

Tong Hao found that the people here have profound insights into a certain type of topic, but they are helpless for comprehensive topics, and most of the topics that Tong Hao does on the earth are topics that integrate many knowledge points, which is why Tong Hao has made such rapid progress, and of course, the help of the system is indispensable.

"Wan'er, this kind of comprehensive topic is indeed difficult to do, but it is not helpless. You see this question is a synthesis of statistics and functions, the first half is relatively simple, everyone can get scores, and the real place to distinguish scores is the function part in the back, which requires a transformation of thinking. In fact, this knowledge is very simple, you only need to think differently and the problem will be solved. ”

"Is it as easy as you say? I really don't see it. ”

"Take your time, there's always an idea. I'll tell you this question first. Look here. The question asks how many pieces of clothing team A needs, first we set an unknown number X, and then ............"

Five minutes later, "This question is really that simple." Why didn't I think of this solution?"

"Wan'er, I believe in you. ”

With Tong Hao's help, Geng Wan'er cleared her mind alone and came back to give Liu Zifei a lecture.

Looking at Geng Wan'er who came back, Liu Zifei's face was full of depression.

"Liu Zifei, I will answer this question. After speaking, Geng Wan'er re-told Liu Zifei according to the method given to her by Tong Hao, and Liu Zifei suddenly realized. The original title can still do this!

Geng Wan'er told Liu Zifei about it again, and found that her thinking was much clearer than just now.

Sometimes lecturing to others is also self-learning!

"Wan'er, thank you. Facing the goddess, Liu Zifei didn't dare to slack off.

"You're welcome, you can ask me any questions you don't know in the future. ”

Liu Zifei found that her talent seemed to be slowly recovering, and the questions that seemed to be astronomical before, now she actually felt a little kind, is this the effect of talent? How many people regard the exam questions as enemies and want to completely conquer them in the examination room, but how many can do this? We might as well change our thinking and regard the exam questions as our own friends, and we may have unexpected results.

In the afternoon, Tong Hao, Geng Wan'er, and Liu Zifei were all studying hard. Tong Hao continued to study the pocket library, Geng Wan'er tackled comprehensive topics, and Liu Zifei continued to review. Everyone is working hard for the college entrance examination!

Thousands of troops, who is the master of ups and downs?

The three-person study group was quickly combined, and during recess, Tong Hao, Liu Zifei, and Geng Wan'er were often seen sitting together discussing various topics.

In a few days, Liu Zifei's mathematical talent has basically recovered, all thanks to Tong Hao's encouragement and Liu Zifei's own efforts!

Death in good times, life in adversity.

Soon it was the appointed weekend, Liu Zifei liked to sleep lazily as usual, and Liu Zifei was woken up by a familiar melody at half past seven in the morning.

"Who?" Liu Zifei asked the person on the other side of the phone dissatisfiedly.

"Zifei, we went to Wan'er's house today, did you forget?"

Hearing the word "Wan'er", Liu Zifei suddenly had a spirit, she was busy studying these days, and Liu Zifei had forgotten her agreement with Tong Hao.

"Brother Hao, you wait for me!"

"We met in the central square, phone. ”

Hanging up the phone, Liu Zifei rushed to the bathroom to wash. Liu Zifei's mother thought she was dazzled, wasn't her son sleeping at this time?

"Zifei, why did you get up so early today?" asked Liu Zifei's mother.

"I made an appointment with my classmates to study together. Liu Zifei said to his mother while brushing his teeth.

"Which classmate?"

"Tong Hao. ”

"Why does this name sound so familiar?Is it the untalented mediocre talent in your class?" Liu Zifei's mother remembered Tong Hao.

"Mom, Brother Hao is not a mediocre talent, he is simply a genius. Liu Zifei retorted.

"Why do you still call him a brother? I tell you, you'd better stay away from him, and review with two people who don't do well in school. "Tong Hao's identity as a scumbag has been ingrained in the minds of every parent.

"Mom, Tong Hao's Zhou Qing results in the first few times have always been the first in our class. Liu Zifei said to his mother.

"I forgot if you didn't mention Zhou Qing, why didn't you bring Zhou Qing's results back to me?"

"Aren't there all of them in the parent group?"

"Shouldn't you tell your mother about this kind of thing as soon as possible?" Every time Zhou Kexin announced the results in the parent group, many parents of students asked some questions about their children in the group. Liu Zifei's mother is busy with work, and every time she opens WeChat, the message is 99+, and she is not in the mood to see what happened on it.

"I see. ”

While speaking, Tong Hao had already finished washing.

"Is breakfast ready?"

"Alright. ”

"Why are there only two?" There were only two breakfasts on the table, one of which Liu Zifei's father had already taken the lead.

"Dad, good morning!" Liu Zifei greeted his father.

"I thought you were going to be in bed today, so I didn't do your part. Liu Zifei's mother's voice came from the kitchen.

"Mom, how can you do this?" The matter has come to this point, and Liu Zifei can only complain.

"It's not a big deal, wait for Mom to make you another one. ”

"It's too late, I've already made an appointment with my classmates. Liu Zifei said.

"Mom didn't say it, let you stay away from Tong Hao. ”

"I know, but this time I have to go. ”
