Chapter 394 (1/2)

But there are also people who take an unusual path.

Several students encountered problems they couldn't do. When they remembered Xing Jiu'An's education, they wanted to ask her.

Xing Jiu'An looked at the topic briefly.

It's simple.

But it's a little difficult.

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

She didn't spend much time in school at that time in middle school, and she often went to the exam, and sometimes even took classes online.

And she didn't study such a course.

Because I don't know how the current progress is, Xing Jiu'An simply wrote two solutions.

”Can you understand?”

“……”

Several students looked at each other.

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

They looked confused.

Other people here also leaned over and looked. Two of them could barely understand.

”Mr. Xing, is this missing steps?” a student who could understand it asked in a low voice.

Xing Jiu'An looked.

She is sometimes very capricious in doing questions. If it weren't for the strict requirements of the teacher, she wanted to write only one answer in the exam.

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

Xing Jiu'An briefly read the other questions in this book.

When she was studying in the original Mongolian school, she carefully studied all kinds of textbooks in China, and she had a good memory. After reading them for a few minutes, she knew when the problem was and how to solve it.
