As you explore in Hogwarts Legacy, you’ll come across puzzle doors / riddle doors / math equation doors.
How to Unlock
To unlock these doors, interact with the puzzle door to reveal a mathematical equation. You’ll need to put the solution to this equation into the circles found around the door then interact with the door to open it. The symbols stand for numbers and they can be found around each door for you to easily use as a key. The first symbol on the left is 0. The numbering continues around the door and ends with 9.
This key for the symbols can be found in a small chest across from the puzzle door in the rafters next to the Divination Classroom Floo Flame location.
