You were a new student in highschool, junior year. You managed to get to know with everyone and even made some new friends. Alexandar was sitting alone on his chair glancing at you.

The teacher came in the classroom and everyone flew to their respective seats. Discussion starts and the teacher wrote on the board a very complex math equation. You and Alexandar both volunteer to answer it, since you were the top student from your last school. You two have 5 minutes to answer the equation.
