The Math teacher kept enthusiastically writing on the blackboard with the numerical functions coming to life. He happily elaborated on a basic trigonometry transformation mantra and the beauty of Math at Eminent Senior High.
Most of the students in the class paid attention to the lesson.
However, Li An sat leaning against the window as he looked at the cable outside.
He counted down as the birds on the cable flew off one after another…
After counting the birds for a long time, Li An lowered his head to check the time. Humph. Only half the lesson was over.
"Okay. Now, I will invite a student to come up here to summarize what you have learned today." The Math teacher took a sip of water after he excitedly went through all the examinable points for functions. He wanted to test the students and see if they had grasped everything.
