Go Up and Do the Questions

"Fu Meng, Guo Miao, Su Su, come up and answer the questions. This is a small punishment for skipping class this morning," Su Dong said.

Su Su looked at the old professor on the stage and frowned.

The three of them walked up to the podium, and a question appeared on the blackboard as flashed out by the projector.

Guo Miao looked at the question for a while, then reached out and started to do it on the blackboard. It was a simple trigonometric question, which was not difficult for her.

However, this kind of question was difficult for Su Su and Fu Meng. The two stood in front of the blackboard, at their wits' end.

Su Su even looked at Su Dong for help.

Su Dong was her uncle and also a math professor at Huaqing University. Su Dong looked at Su Su sternly, signaling her to answer the questions properly. Then, Su Dong looked at Guo Miao.
