Due to Li Guoxiang’s insistence, the director had no choice but to ask Li Guoxiang to call Professor Xu over.
Professor Xu had done a lot of research in the academic field of mathematics. Although he was already over 70 years old, he was definitely a leading figure in the field of mathematics.
Although Li Guoxiang’s personality was not very good, he still made a lot of contributions to the school. The class he led each year had the highest graduation rate in the entire province.
However, he did not want to offend Jiang Li.
Therefore, Li Guoxiang could only look for professor Xu. If Jiang Li really lied, he could still have an explanation in front of the principal.
As for how to deal with Jiang Li in the end, Li Guoxiang would have to wait for the principal to come back.
In less than ten minutes, Professor Xu arrived.
It was an old man with half-white hair who was full of energy. He wore a pair of glasses and looked very knowledgeable.
Jiang Li took a look at him. This kind of old professor gave off a very comfortable aura. It seemed that he was easy to talk to and not some weirdo.
Professor Xu did not want to come at first. Why did he have to deal with this student’s mistake? If he had not heard that it was the student who solved the problem yesterday, he would not even want to leave his laboratory.
“Professor Xu, sorry to disturb you.”
The director lowered his posture and bowed to Professor Xu to apologize. He knew Professor Xu’s position here.
“Professor Xu, it’s her, she…”
Li Guoxiang was about to blame Jiang Li to professor Xu, but was interrupted by Professor Xu with a wave of his hand. He did not even look at Li Guoxiang.
Instead, Professor Xu looked at Jiang Li.
“Are you the student who solved the problem?”
“Yes.”
Seeing that Jiang Li did not have stage fright at all and that her aura was not lower than the surrounding teachers, this student was amazing!
“Well, she’s not bad-looking, has a good temperament, and a good personality.” Professor Xu raised his glasses and added, “She’s also smart.”
“Huh?”
Everyone was a little confused, and Jiang Li had a rare look of puzzlement on her face. How could this old professor see so many things at one glance?
‘However, he indeed had good taste,’ Jiang Li thought in her heart. Professor Xu had much better taste than these old foxes in the office.
Jiang Li could not help but have a good impression of this old professor.
“Are you the one who solved this question?”
Professor Xu picked up the A4 paper on the table. The handwriting was neat and delicate, like Jiang Li herself.
“The handwriting is also good.”
The other teachers in the office, “…”
If they remembered correctly, Professor Xu rarely praised people like that.
“Tell me, what is your idea of solving this problem?”
Professor Xu handed the question to Jiang Li, and the others pricked up their ears to listen. When Professor Xu was talking here, the others did not dare to interrupt him. Even Li Guoxiang had become much more obedient.
Jiang Li pointed at one of the steps with her slender and fair fingers.
“When I first got this question, I discovered that there were two conditions wrong with this question, as well as one unit of quantity.
“I’ve seen this question on Country Q’s academic website before, and the research on this question was only introduced two years ago in our country. The mathematics community in Country Q only solved one-third of the first step, but the subsequent steps have never been solved.”
Professor Xu nodded in recognition of Jiang Li’s words.
Many people knew about this academic problem, but few people knew that it originated from Country Q.
“So, I remember the original form of this problem, and many scholars focus their research on solving the problem according to the method given by Country Q, but they never thought there was a simpler calculation method.”
“You mean to use the element exchange method?”
“Yes.”
Jiang Li unhurriedly explained her solution to the problem.
When Professor Xu saw the solution to the problem today, he still did not quite understand. The element exchange method was a simple high school mathematics solution, how could it be used for such a complex and difficult academic problem?
However, after a day of research in the laboratory, he finally understood one thing.
It had to be said that many people were misled by this complex problem, thinking that the more complex the problem, the more steps and techniques needed to solve it.
However, it was often easy to take a wrong path.
How many people would have the courage and boldness to use the simplest method to calculate this academic problem like Jiang Li?
Perhaps even the most experienced and authoritative scientists might not be able to do it. On the contrary, they would always be bound by the habitual thinking of the past.
Without a doubt, Jiang Li had opened up a new way of thinking.
In order to make her thinking easier to understand, Jiang Li directly sat at a desk at the side, took a pen and began to explain while writing down the steps to solve the problem
The further she went, the more shocked professor Xu became. The problem that he was still pondering in the afternoon seemed to have started to have a direction.
As Professor Xu continued listening to Jiang Li’s explanation, he also asked questions from time to time, and Jiang Li quickly and accurately gave an answer.
Such a scene was like a dream in everyone’s eyes, and it was a terrible nightmare.
