It was Saturday.
As usual, Gu Bai bought a small yellow car at the school gate and rode it towards Li Sisi's house.
Although Gu Bai had a huge sum of 10,000 yuan on him now, which was enough for his tuition fees for the next semester, and even his living expenses, he still had to save some money.
but... No matter how small a mosquito was, it was still meat.
Lu Yuan didn't give up on his job of tutoring for 200 yuan a week.
These days, Gu Bai did not continue to write theses for others. Instead, he stayed in the library obediently.
She wanted to ask him why he was going to the library.
em.....
Of course, it was to solve the Zhou's conjecture.
Unfortunately, even with the blueprint provided by the system, Gu Bai still felt that something was missing. He could not abandon the blueprint and rely on his own ability to solve it.
As for what went wrong, Gu Bai did not know. Perhaps…The only thing missing was a hint of inspiration, or perhaps an opportunity?
Very quickly.
Gu Bai arrived at the neighborhood where Li Sisi lived.
After parking the shared bicycle, Gu Bai paid two yuan and immediately entered the neighborhood that was not considered luxurious but was still very luxurious.
Knocking on the door of Li Sisi's house, the person who opened the door was still Li Sisi's mother. When she saw Gu Bai, Liu Ping's face revealed a hint of joy."Teacher Xiaobai is here?"
During this period of time, her daughter, Li Sisi, had improved by leaps and bounds. Even Li Sisi's teacher had called her to praise her.
This made Liu Ping very happy. This was also the first time she received a call of praise from her child's teacher.
She knew the reason why her child's grades had improved, so she was much more polite to Gu Bai.
"Yes." Gu Bai nodded with a smile.
"Li Sisi, Teacher Xiaobai is here.”After preparing the slippers for Gu Bai, Liu Pingping shouted towards Li Sisi's bedroom.
"Teacher Xiaobai, you're here." It was obvious that Sinead hadn't just woken up. It could be seen from her carefully tied ponytail.
"Teacher Xiao Bai, do you know how many marks I got on the math test this time?”Li Sisi, who had her hands behind her back, was half a meter away from Gu Bai. She raised her head and looked at Gu Bai, who was changing his shoes, with a mysterious expression.
"How many points? 90？”Gu Bai asked curiously.
Li Sisi's previous math results were not good, but of course, they were not bad either. In their class, she had always had average results. Otherwise, she would not have been trained by Gu Bai.
However, Gu Bai was more concerned about Li Sisi's results since his first trainee had awakened her system here that day.
"100, I got a full score of 100!”
Li Sisi took out the test paper from behind her back and showed it to Gu Bai. She smiled cheekily.
Seeing Gu Bai take the test paper and look at it, she continued to add,"And…I'm the only one in our class who got full marks. I got first place.”
Li Sisi was a little excited. She held Gu Bai's arm and jumped happily.
Gu Bai coughed awkwardly as he thought of words of praise.
Gu Bai really couldn't think of a way to praise her for scoring full marks on her elementary math test.
In his opinion, if it didn't involve college or university exams, or a 'world problem conjecture', it shouldn't be praised.
Wasn't it fine as long as he had hands?
Fortunately, Gu Bai did not need to think of any words of praise. Li Sisi's mother, Liu Ping, was already extremely excited.
"100 points!"
"Sisi, why didn't you tell me?”
"Moreover, you even ranked first in the class!!! Amazing, too amazing."
"That's great, that's great. Sisi, tell me what you want to eat for lunch today.”
Li Sisi did not seem to care much about the food. She said,"Anything is fine." Then, she followed Gu Bai and started the math tutoring session.
It was still the primary school Mathematical Olympiad exam paper.
Li Sisi would do it first, and Gu Bai would explain it to her when he met someone he didn't know.
It had to be said that Li Sisi's mathematics results had improved a lot. At least, it was not as simple as the 100 points in the ordinary primary school test.
There were only two questions that he didn't know how to answer in the elementary school Mathematical Olympiad exam paper.
Glancing at the question, Gu Bai explained without thinking,"This is a common project cooperation problem.”
"As you can see from the question, A's work efficiency is 1/20, B's work efficiency is 1/30, and A and B's cooperation efficiency is 1/20*/5 1/30*9/10=7/100. Also, because it is required that 'A and B cooperate for as few days as possible', we should let..."
"In the end, the cooperation between A and B will take at least 10 days.”
Gu Bai quickly wrote down the answer. Out of habit, he twirled his pen and asked,"Do you understand?"
Gu Bai's current teaching had a 40% comprehension, 30% memory, and 40% inference. He did not have to worry about Li Sisi not understanding him because he spoke too fast.
"Understood." Li Sisi nodded in realization and said,“... Actually, it wasn't just an engineering problem. Some of the solving efficiency was similar to the color sphere.”
"You're worth teaching." Gu Bai replied lightly.
His ability to draw inferences was immediately demonstrated.
"Teacher Xiaobai, you're too amazing!”
After sorting out the knowledge points in her mind, Li Sisi's eyes widened and flashed. She looked at Gu Bai with admiration and said,"Our math teacher has to think for more than ten minutes when he encounters such a problem. You... He actually solved it instantly without thinking."
As if feeling that being praised by a primary school student was not something to be proud of, Gu Bai changed the topic and asked curiously,"Which university did your math teacher graduate from?”
"Nankai."
？？？
Now, even primary school teachers were like this?
"What's wrong? Is there a problem?”
"No, no problem. It's just that I feel that your math teacher's university…It's pretty good."
"Hehe, our language teacher is even better. She's from Yanjing University.”
Gu Bai was speechless.
Curls, crazily curls.
A brilliant student from Yan University actually taught elementary school!
"Alright, let's continue with the questions." Gu Bai didn't talk about these related things anymore. He felt a blow to his heart.
He was just an ordinary university student. Was he unable to survive in society now?
After explaining a few more questions, the phone in Gu Bai's pocket vibrated.
Gu Bai stood up and walked to the balcony that led directly to his bedroom. He looked at it curiously and saw that it was Senior Wu Hai calling.
"Gu Bai is in trouble!"
As soon as the call connected, Senior Wu Hai's panicked and deep voice came through.
Something happened, what happened?
However, before Gu Bai could ask further, Senior Wu Hai hung up the phone and sent a message.
"Come quickly to lecture hall 201.”
Gu Bai's eyebrows twitched as he read the message. He had a bad feeling.
