Classroom 7A is a classroom where Arithmancy classes are taught at Hogwarts School of Witchcraft and Wizardry. It is located off of the Serpentine Corridor on the third-floor of Hogwarts Castle, next-door to Classroom 3C and around the corner from a corridor where the staffroom sometimes exists. It includes number charts, a blackboard and rows of tables for students to sit in.
Behind the scenes
- In the Game Boy Color version of the video game adaptation of Harry Potter and the Philosopher's Stone, two equations are seen written on the blackboard: 2 ⋅ xy = 16 and xy = 14. Assuming that these two equations are meant to represent a system of linear equations, the values of x and y are unsolvable.
