However, there were also those who didn't take the ordinary path.
A few students encountered questions that they didn't know how to do. They thought of Xing Jiu 'an's educational background and wanted to ask her.
Xing Jiu 'an simply looked at the question.
It was quite simple.
But it was also a little difficult.
The key was that she didn't know which solution she should use.
She didn't spend much time in school during her middle school days. Most of the time, she went to take exams and even had online classes.
Besides, she didn't take such a course back then.
Since he didn't know the current progress, Xing Jiu 'an simply wrote down two solutions.
"Can you understand it?"
"..."
The students looked at each other.
What kind of formula was this? What was the solution? How did that step end up like this?
They were all dumbfounded.
