Classroom 7A  is a classroom where Arithmancy classes are taught at Hogwarts School of Witchcraft and Wizardry. It's located on the seventh floor of Hogwarts Castle, near Classroom 7B, Classroom 7C and the entrance to Gryffindor Tower. 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.
