But there are also people who don't take the usual path.

Several students encountered problems that they couldn't do. Thinking of Xing Jiu'an's academic qualifications, they wanted to ask her.

Xing Jiuan glanced at the subject briefly.

It's pretty simple.

But it is also a bit difficult.

The point is that she doesn't know which solution to use.

She didn't have many days in school during the middle school period, and she often took exams, and sometimes even took classes online.

And she didn't study such a course at the beginning.

Because he doesn't know the current progress, Xing Jiu'an simply wrote two solutions.

"Can you understand?"

"..."

Several students looked at each other.

What formula is this? What solution? Why did that step jump to this step?

They looked dumbfounded.

The other people here also leaned over to take a look, and there were two who could barely understand some.

"Ms. Xing, is this missing steps?" a student who could understand a little asked in a low voice.

Xing Jiuan looked at it.

Sometimes she is self-willed to do questions. If it were not strictly required by the teacher, she wanted to write only an answer in the first exam.

She also wrote a few more steps to guide the students this time.

Xing Jiuan glanced briefly at the other questions in the book.

When she was studying in Yuanmeng School, she had studied all kinds of textbooks in China carefully, and she had a good memory. After reading it for a few minutes, she knew when the topic was and what method should be used. To solve the problem.

She took a pen and wrote briefly, and wrote as many steps as possible to make them look more convenient.

Xing Jiuan's lecture is similar to what she taught the trainees in the training ground.

The topic is: first this and that, then bring in the formula, and then this, this and that to get the answer!

In the training ground, do it by yourself first, let them watch and let them understand by themselves.

The students listened to it again, looked at the formula, and then looked at Xing Jiu'an's particularly beautiful characters, becoming more and more confused!

"Understood?" After Xing Jiu'an finished speaking, he didn't hear a response, and asked with some doubts.

Then, she saw that most of the people who were listening to the lecture were blank.

Xing Jiu'an was also at a loss.

As soon as she wanted to speak, Su Yize said in surprise, "I understand, I understand, sister, I understand."

He knew this question originally, but Xing Jiuan said it rough, and he could accept it.

Xing Jiu'an was not surprised that he suddenly turned the little elder sister into a sister.

Just listen to Su Yize and then immediately said, "Sister, according to your way of lecturing, I think you can only lecturing to Super Xueba."

Xing Jiuan looked at him suspiciously.

She also feels that she has spoken well.

Not many steps are omitted.

"why?"

"I don't understand." Su Yize seemed to be worried too. He looked at Xing Jiu'an's draft paper that gave the answer in just a few lines. "If it wasn't for me, looking at these lines of answers, I might want to Think about it for a while."

Thinking of how full the teacher wrote on the blackboard every time he talked about math problems, Su Yize sighed. Fortunately, his little sister did not go to class, otherwise, it would be very boring.

If you can get the answer by simply looking at it, you still have to listen to the teacher for a few minutes or even ten minutes. It may be too noisy to sleep!

This is a super outline question. There are too many super outlines. The students who came to the question thought that they were doing well in their studies, and they were the kind that could be called a master in the class. As a result, after listening to Xing Jiu'an, they were shocked.
