When I was five years old, I helped my mother do test papers live, and I became popular

"Am I transmigrating?"

Standing in front of a mirror, Ye Xiaotian stared dumbfounded at the people inside.

Inside the mirror, there is a little boy carved in jade.

About 5 years old, very cute, and a little handsome.

Just when Ye Xiaotian was stunned, a young lady came over, picked him up, walked into the room, and put him on the bed.

The young lady stuffed Ye Xiaotian with a lollipop, touched his head, and said softly: "Xiaotian, play here well, don't demolish the house, mom, I'll broadcast live to earn tuition for you."

"Mun!"

After kissing Ye Xiaotian on the cheek, the young lady came to the computer in a lot of steps, turned on the live broadcast device, and took out a set of test papers.

Start reviewing.

Do test papers live.

Ye Xiaotian looked at the mother of this body, and now she is also his mother.

My mother was very young, she wore a light blue dress, she didn't put any makeup on her face, her skin was snowy, her facial features were exquisite and delicate, giving people a feeling of first love.

Lin Shiqing is 24 years old. She has just graduated from a bachelor's degree and is preparing for a postgraduate exam. By the way, she broadcasts live to earn a little money to pay Ye Xiaotian's tuition.

[Gouqing, the live broadcast is finally live]
[Student, please start your performance]
[A good day begins with watching Gouqing being tortured by a high number]
[Seeing Gou Qing, a scumbag, I feel like I can do it again]
When the live broadcast just started, there were more than a dozen people, all of whom were old fans of Lin Shiqing. They were so idle that they often watched her live broadcast to do quizzes.

"Hello everyone."

Lin Shiqing said hello, then buried her head down and started to do the questions.

1. Let A be an n-order non-zero matrix, E be an n-order unit matrix, if A3 =0, then

(A) E -A is irreversible, E + A is irreversible

(B) E- A is irreversible, E+A is reversible

(C)EA is reversible, E+A is reversible

(D) EA is reversible, E + A is irreversible

[Is the first question so exciting]
[Based on my nursery school diploma, what the hell are these things? ]
[I think this question should choose B]
[why? ]
[Because I am familiar with B, I often pretend]
[logic genius]
Seeing the first multiple-choice question, Lin Shiqing had one head and two big ones. She didn't expect it to be so difficult at the beginning.

"Everyone wait."

Lin Shiqing rubbed her head, stood up and said, "I'll eat a popsicle first to calm my shock."

After returning with a popsicle, Lin Shiqing began to write vigorously on the paper, and finally concluded that it was D.

"This question should be D."

After filling out a D on the test paper, Lin Shiqing said something to the screen, and then continued to the next question.

……

7. Among the following functions, the non-differentiable at x=0 is ( )
A .f(x)=｜x｜sin(｜x｜)
Bf(x)= ｜x｜sin(√｜x｜)
C. f(x)= cos(｜x｜)
D .f(x)= cos(√｜x｜)
"For question 7, you should choose B."

After doing this, Lin Shiqing collapsed a bit.

What a difficult question!
I feel that after finishing this test paper, I may become bald.

"Gollum!"

There was a slight rumbling sound in his stomach.

Lin Shiqing's face was serious, and she said awkwardly to the screen: "Everyone, wait, I'll go to the bathroom, and I'll be back later."

Before she finished speaking, Lin Shiqing ran away.

[Do fairies have to shit too]
[Haha, fairies can not only shit, but also fart and pick their noses]
[Don't pass on Yao, don't believe in Yao, fairies can't shit, sister Qing was scared away by the question]
[Hey, there is a little Zhengtai over there]
[he is walking towards us]
[What is he coming for? ]
[It must be to show cuteness]
Ye Xiaotian came to the computer, climbed onto the chair, sat down, and glanced at the live broadcast room.

Good guy, it's deserted enough.

Only 11 people were watching, and the reward was only 5.2 yuan, all of which were given by a net name "Sister Qing's Wife".

[little brother, give auntie a smile]
[Upstairs note, starting from three years, the maximum death penalty.Please let me come, little brother, give Aunt Meng a]
[Ni Zukai, you are all bad guys, Xiao Zhengtai is mine, come quickly to my sister's arms]
Looking at the live broadcast room, a group of people were molesting him, Ye Xiaotian was speechless, looked down at the test paper, and ignored the group of female hooligans.

Nowhere to put the handsome ah!

[What is little brother doing? ]
[Is he going to do a test paper? ]
[Haha, ignorant 13, so cute]
[Little brother: What are these? It’s so scary! ]
In the live broadcast room, a female netizen was teasing Ye Xiaotian, but he didn't know it, he was in a daze.

He was stunned not because he was frightened by the question, but because he was frightened by a voice.

[Scholar system is being bound]

In Ye Xiaotian's mind, the above voice sounded.

【School Master System Binding Successfully】

Soon, in Ye Xiaotian's mind, the following page appeared.

【Host: Ye Xiaotian】

【Scholar value: 0】

[language: lv0 (0/100)]

[Mathematics: lv0 (0/100)]

[English: lv0 (0/100)]

[Physics: lv0 (0/100)]

[Biochemistry: lv0 (0/100)]

【Information: lv0 (0/100)】

【Material: lv0 (0/100)】

system coming?

Of course Ye Xiaotian knows that the system is a must-have artifact for traversers.

Help the traveler reach the pinnacle of life and marry two Bai Fumei, one for day and one for night.

[Gift novice gift package x1]

"Open the novice gift bag."

[Congratulations to the host for obtaining the Xueba Experience Card x1, valid for 3 hours]

After regaining his senses, Ye Xiaotian started to read his mother's test paper, picked up a pen, and calculated the first choice on the paper.

In his previous life, Ye Xiaotian was a college student.

It is not easy to do high math problems, and there is no need to use the Xueba experience card.

Because (EA)(E+A+A)=EA=E(E+A)(E-A+A)=E+A=E.

So it can be seen that EA is reversible and E+A is reversible.

Based on the above, the correct answer to this question is C.

The first question should not be D, but C.

Mom made a mistake, confirmed, mom is a scumbag.

What Ye Xiaotian didn't know was that when he was doing the questions, the live broadcast room was stunned.

[little brother is doing advanced math]
[Look, he really can do it]
[I confess, there is still a process]
[If you really choose C, I knew that Gou Qing’s answer would not be correct]
["Qingqing's Wife" sends a rocket x1]
["Riding a donkey to seduce a boy" gives out shark fin x20]
["Exercising your right hand often" gives out shark fin x15]
……

The gift "嗖嗖嗖" rose, and the live broadcast room gained a certain popularity, and got a small recommendation from the Douhu platform, and more and more people entered the live broadcast room.

Those who have just entered are a little confused.

What is this little lady doing?
There is also a test paper next to it. Is it a primary school test paper being broadcast live?
