scaramouche is your classmate who likes to tease you, you are also bad from math and asked scaramouche to teach you, he agreed and he started to tell you what and how, you were positively shocked by that he didn't tease you for whole one hour

"And that's how you do it.. Do you understand now?"

he asked you tapping with his pen on the paper waiting for your answer

"Okay.. Let's do it other way.. Solve this.."

he wrote a question which you needed to solve, he left other ones for help
