This guide will walk you through solving the Arithmancy’s Classroom Puzzle Doors — this set of three puzzle doors is just over the wooden-boarded walkway from the Divination Classroom’s Floo Flame. In order to open each door, players will need to put the correct symbols on each of the two question mark panels in the area. The player can cast 
Revelio to make the panels glow blue.

Solutions for All Puzzle Doors
First Door
The symbol panels to open the first puzzle door are very close to the door itself. If you search on the desk in front of the door, you will find the reference sheet outlining which symbols are which numbers. The double question mark panel is to the right of the first door, and the single question mark panel is to the left of the door. The correct symbol for the double question mark panel is the Three-headed Snake, and the correct symbol for the single question mark panel is the Owl.
For the first puzzle door, shown below, we can see that the top triangle for the single question mark panel was 2 + 3 (Three-headed Snake) + ? Owl (4) = 9. Additionally, the bottom triangle was 0 + 1 + ?? Three-headed Snake (3) = 4.
Second Door
Once you walk past the entrance and into the classroom, the second door is on your left. The symbol panels to open the second puzzle door are very close to the door itself. The double question mark panel is to the right of the door, and the single question mark panel is to the left of the door. The correct symbol for the double question mark panel is the Crab, and the correct symbol for the single question mark panel is the Owl.
For the second puzzle door, shown below, we can see that the top triangle for the single question mark panel was 5 (Crab) + 6 (Lizard) + ? Owl (4) = 15. Additionally, the bottom triangle was 13 + 0 (Otter) + ?? Carb (5) = 4.
Third Door
The third door is in the same room, but straight across from where you entered. The symbol panels to open the third puzzle door are very close to the door itself. The double question mark panel is to the right of the door, and the single question mark panel is to the left of the door. The correct symbol for the double question mark panel is the Unicorn, and the correct symbol for the single question mark panel is the Lizard.
For the third puzzle door, shown below, we can see that the top triangle for the single question mark panel was 5 (Crab) + 6 + ? Lizard (6) = 17. Additionally, the bottom triangle was 7 (Squid) + 0 + ?? 1 (Unicorn) = 8.
How the Number Puzzle Works
If you’re curious why those panels were correct, they each represented a number that solved the number puzzle on the door. Each of the symbols has a number, and when those numbers at the corner of each triangle add up to the number in the middle, the door will open.
