"Okay." Zhang Rui was very serious about the topic.

An Ning devotes herself to various inferences, one problem after another.

Zhang Rui sat aside and watched An Ning write, and sighed. "An Ning, you are really smart. This question is so difficult, you have done it step by step!"

"The final conclusion has not been reached yet, so it is not clear whether my solution to the problem is correct." An Ning said seriously.

"I think it's about the same."

Soon, An Ning deduced the last question, and listed various inference proofs on a blank paper.

Zhang Rui said very enviously. "You see, I know that your problem-solving direction is right. I just couldn't think of it, but as soon as you write these, I thought of it."

"Yeah." An Ning nodded.

Zhang Rui took it over and thought about it, and ticked it on the question paper. "An Ning, you said I would first prove these two problems, and then the same can be proved, and then prove the fourth step of the problem. Is this OK?"

An Ning thought about it. "It should be right, and your thinking is also very clear."

Zhang Rui said modestly. "This is the answer I only thought of under your prompt, and I can't say how smart I am."

"It's much simplified than mine." An Ning smiled.

Zhang Rui has always been like this in her studies. She likes to ask her if she doesn't know how to ask her, but then she has to come up with another solution to the problem, which seems to prove that she is also very smart and not stupider than her at all.

An Ning had already seen through her this point and didn't think it was anything. Anyway, one person had his own personality.

Zhang Rui humbled herself again. "But my idea may not be correct. By the way, An Ning, did you get a software on your phone and just type a question into it and the results will appear?"

"Yes, do you want to do it too? I can tell you which one to do it." An Ning said.

Zhang Rui wrinkled her nose. "I want to do it too, but my phone space is not enough and I can't do any software. An Ning, please answer me on your phone. I want to see what other ideas to solve this problem."

An Ning smiled. "I think it's just a question. We have mastered a method, right? Why do we have to dig into this question?"

Zhang Rui was frowning and said with no choice. "Aren't I tutoring for other students now? If I don't master more, how can I let my children and parents trust me? I have no choice!"

People just borrowed their phones, and An Ning was embarrassed to refuse. She opened the phone and entered the question into the software. Soon many ideas for solving the problem appeared.

Zhang Rui showed a particularly surprised expression. "This software is really amazing. It has so many ideas. An Ning. No wonder you don't have the hard work of studying, but your grades are never worse than mine."

An Ning almost came up in one breath. She seemed to rely entirely on mobile phone software, so she could learn well.

You should know that she rarely uses these things, and she just downloaded them.

"An Ning, you can ask me to study it myself? If it is very useful, I decided to change the phone number and have larger memory, so it will be much more convenient for me to make up for my children, and I don't have to study it for so long."

"Yes, take a look. Anyway, use this software and you can read the difficult-to-solve ideas of the problem, and you will know it."
