The homeroom teacher did not believe that a lousy student could solve this question, so he agreed.
"I will help you after you solve this."
Hearing this, Qin Shu looked away and began to work on the question on the blackboard.
Under the podium, the students who had been working on something else stopped. Even the students who had dozed off opened their eyes to watch Qin Shu fail to answer the question and be made to stand outside as punishment.
Qin Shu took out a piece of chalk and used different formulas to solve the problem step by step.
The homeroom teacher lowered her head to look at the book. When she looked up at the blackboard, she was stunned.
How was this possible?
How did Qin Shu know how to solve this problem?
Qin Shu turned to look at the homeroom teacher. "I'm done. "
