The boy in yellow stood up with a dumbfounded look on his face.
"Professor, that... I'm not a student of this class..."
Professor Fang chuckled.
"I know. You're not a student of this class, yet you still came here to listen to the lecture. It can be seen that your enthusiasm for learning is high! Come, come up here and write the solution down!"
The boy in yellow blushed in embarrassment.
"... Professor, I'm from the Faculty of Arts..."
They didn't study Advanced Mathematics either!
Professor Fang's face was filled with regret.
"Ah, is that so..."
That meant that he really would not be able to do it.
After all, when it came to Advanced Mathematics, he would only be able to do it if he was familiar with it. If he did not know it, then he would not be able to do it.
He put his hand down.
"Alright, then sit down."
The male student in yellow immediately heaved a sigh of relief.
