Xueba: The Knowledge I Teach, The Crit Is Returned

Parallel worlds, Blue Star.

=========

topic:

[A and B are climbing the mountain. A reaches the top of the mountain and B is still 400 meters away from the top of the mountain.

【How high is the mountain? 】

In a small but warm bedroom in the 'Princess Room', the young man frowned and stared at the questions on the exercise book.

He....is trying to solve this problem.

The young man is Gu Bai, a freshman at Linhai University.

Gu Bai, who came from a mediocre family, chose to work part-time in his freshman year.

Not serving dishes, not handing out flyers, but tutoring.

Or 1vs1 kind.

Because he had no previous teaching experience, Gu Bai did not choose to teach middle and high schools, but a simple elementary school.

Elementary school tutoring?

Simple, easy, easy, just have a hand....

As a contemporary college student, Gu Bai teaches elementary school students to be confident and take a proper dimensionality reduction attack.

However.

The fact was beyond Gu Bai's expectations.

The dimensionality reduction attack did not happen, it was simple and easy, and the feeling that you could do it with your hands did not happen.

On the contrary... Gu Bai felt a little tired.

Of course, if using the equation method, Gu Bai can solve it.

But...it's an elementary school subject, and 6th graders don't learn multivariate equations at all.

He Tan's equation solves this problem.

Faced with this question, Gu Bai had to get serious again and changed his mind.

The brain is running at a high speed, thinking of various ways to solve the problem in front of me.

However.

Gu Bai was still helpless.

"I'm a college student anyway. Although I'm not a famous brand, is it so difficult to deal with elementary school problems?"

"Don't you go to a fake university?"

"Or....now the primary school topics have begun to be inscribed?"

Gu Bai sighed, doubting life.

"Teacher, I have another question that I don't know."

At this moment, Li Sisi handed over the test paper in his hand and pointed to another question on the test paper.

Gu Bai smiled and looked at the question, wrote it down silently, and then got up and said, "Sisi, you should continue with the question below. Teacher has drank too much water and needs to go to the toilet."

After that, Gu Bai calmly got up and walked towards the bathroom, ready to ask Qiandu for help.

......

Close the door.

Gu Bai washed his face with water and let himself relax.

Good guy, it was really embarrassing just now.

The dimensionality reduction attack was not achieved, but it was not done by primary school questions.

You guessed it right, the second question asked by Li Sisi, Gu Bai may still not do it....

woohoo~~

Taking a deep breath, Gu Bai cleared his mind.

Volume, now the primary school topics are really too volume.

Drying his hands with a paper towel, Gu Bai immediately took out his phone and turned it on, and searched: [A and B climb the mountain, A reaches the top of the mountain and B is 400 meters away from the top of the mountain...]

In an instant, many web pages pop up....

Just when Gu Bai was about to click a ready to view.

The voice of the mechanical version came from my mind.

"Ding, ding, ding."

"Super teaching system binding..."

"The super teaching system will be successful."

Hearing the mechanical sound in his head, Gu Bai was stunned for a moment, and then a look of joy appeared on his face.

He has read novels, and he has to read novels for several hours every night before falling asleep.

So he is not unfamiliar with the system at all.

After understanding the function of the system, Gu Bai's eyes lit up.

The super teaching system, as the name suggests, is for teaching.

However, according to Gu Bai's simple understanding of the system just now, he found that the system is not as simple as teaching.

The system not only has the ability to teach buuf, but also has the function of 100 times the return of teaching.

Return what? There is no description on the system.

A panacea? Genetic medicine?

Shouldn't currently.

The high probability is related to the topic and knowledge.

After Gu Bai thought about it, he was overjoyed.

He is not greedy, although the system is not directly invincible, but...with this teaching system, it is only a matter of time to become a super scholar with this teaching system.

Gu Bai did not continue to study the system in depth. After reading the answers to the questions given by netizens on Qiandu, he straightened his hairstyle in front of the mirror and smiled lightly: "Xueba's sea of ​​stars starts from teaching elementary school students math problems... .."

......................

"Teacher, why do you take so long to go to the toilet?"

As soon as I entered the door, I heard Li Sisi's voice.

At this moment, she raised her head and widened her big eyes. She said suspiciously, "Teacher, are you going to Qiandu?"

"how is this possible."

Gu Bai, who was told, didn't panic at all. He smiled calmly and said, "I still use thousands of degrees for a mere elementary school question. You underestimate college students."

He walked to Li Sisi's desk, pulled the stool and sat down, habitually turned the signature pen, copied the draft and said:

"Come on, look at the question."

After that, Gu Bai quickly wrote and drew on the scratch paper.

"The quantity given in the question includes distance, speed, and time. From the question, it is not difficult for us to conclude that the time used by them is the same.

Therefore, when the two people walk for the same time, the distance between the two people satisfies the relationship of "speed difference × time = distance difference".

When going up the mountain, A leads B by 400 meters. When going down the mountain, if A and B start from the top of the mountain at the same time, since the speed of the two people doubles at the same time, the time for A to go down the mountain becomes half of the time for going up the mountain, "the speed difference doubles and the time becomes 1/2", so when A reaches the foot of the mountain A is still 400 meters ahead of B..."

"...So, in the end, it can be concluded that the distance up the mountain is 2,400 meters, that is, the height of the mountain is 2,400 meters."

In any case, Gu Bai is also a contemporary college student.

After seeing the answers given on Qiandu and understanding the logic of the question, Gu Bai quickly straightened out the key points of the question.

The key point of this mountain climbing problem is that the time is the same, and the distance ratio is obtained by using the speed ratio, and then the mountain height is obtained.

Soon, Gu Bai asked for the final answer. He smiled and looked at Li Sisi and said, "The final result is 2400m. Is it easy?

Primary school topics just want to get involved with me, but there is no door.

No, the door is welded for you.

After solving this problem, Gu Bai finally vented the unhappiness in his heart just now.

Can I, a college student, be stumped by elementary school topics?

"This..." Li Sisi sitting on the seat was a little bit incredulous, her small mouth opened slightly and her eyes widened.

Of course...not because Gu Bai solved the problem, but because she...

understood.
