Shi Ning's eyes fell on the book, and then his body slowly leaned away. He then landed on Lu Shian's hand and looked at the math problems in the book very seriously.

Since I learned last night that Lu Shian, Xi Qinghuan and Qi Bo have started to learn advanced mathematics by themselves. Now, when I see the advanced mathematics question bank he holds in my hand, Shi Ning is already very calm.

What Director Xu and Yang Qiwei said was no longer within the scope of their attention. Shi Ning even took out a draft and a pen from his schoolbag, and wrote it while writing: "The limited coverage theorem requires two points. One is that the coverage must be a closed range, and the other is that the closed range must be an open range. The closed range or a half-open and half-closed range is not true. Generally, when there is a wrong thinking, it is not differentiated. Let me take a look..."

While speaking, he started writing on the draft book, and he didn't listen to what Director Xu and Yang Qiwei were saying.

Yang Qiwei had been chatting with Director Xu for a while, but he didn't pay attention to what the two were doing. Until Yang Qiwei glanced at them, he stopped talking and smiled at Director Xu with a serious expression: "Director Xu, the questions you are worried about are now given you the best answer."

Director Xu looked at him and saw that the two students they had been discussing were doing the questions very seriously... He almost started arguing with his parents, and they still had the heart to do the questions?

After listening carefully, Director Xu was so shocked that his fingers trembled.

"According to Dedekin's theorem, there is a unique real number η, so that η is the dividing point of a and b, then..." Shi Ning said softly while writing, focusing on what happened around him, blocking it all, "...Suppose the set composed of this limited open range is h1..."

"I'm here to solve the error..." Lu Shian, who was holding the pen in his hand, tapped lightly on the draft paper with the tip of the pen, leaving a few extremely small black dots. "The minimum value is solved, and there is no way to calculate it later."

"Qinghuan is the answer here..." So, both of them were wrong, and they insisted on themselves, but there was no result.

Shi Ning nodded and carefully analyzed, "It's very correct. The easier the finite coverage theorem is, the more likely it is to make mistakes. Your mistakes and Xi Qinghuan are the most common mistakes."

The pen in his hand kept stroking on the draft paper, and finally turned the page and continued to write down. The moment the paper was turned over, the light shone through the paper, and Director Xu saw that the side of the paper was full.

The finite coverage theorem, Dai Jin's theorem... are all high-level mathematics in college. Shi Ning and Lu Shi'an have already started discussing high-level mathematics!

"Director Xu, we have been staring at them for three minutes. The two of them have no influence and have not noticed us at all. You said, is it a bad thing for them to fall in love with them early?"

"No, for them, early love is just a adjustment, and they will even encourage the two to study together and compete together. I know the two children very well. They will strictly restrain themselves, help each other, solve the problems in learning together, and supervise each other."

Yang Qiwei was defeated by the two of them. He racked his brains to convince the director who existed like the "Queen Mother". He never thought that the two of them still had the intention to do the questions together.

It was also considered a mistake and became the most evidence to convince Director Xu.

What else can Director Xu say? A high school god and a junior high school god. When they have an early love relationship, they can discuss advanced mathematics. What else can he say?
