How to solve the 4 door algebra puzzle on the 4th floor of the Evil Spirit Club in Persona Q

While exploring the 4th floor of the Evil Spirit Club labyrinth in Persona Q, you’re going to encounter a sort of algebra-looking puzzle that you will be required to solve to progress further in the game. This tutorial lets you know how to solve it.

You should find three pieces of a ripped paper with the following :

Top: +a+b-a+c-d-b
Middle: +c-b+a+a+c-a
Bottom: -b-b+b-d+a+c

Place the icons in their respective positions as seen in the highlighted area of the screenshot above. “1” should go to the top-left room, “2” should be placed on the bottom-right room, “3” should be on the top-right room and “4” should go on the bottom-right room.

After placing the symbols on your map, move your character in the following directions below :

1. Starting from room 3, go to room 1.
2. From room 1, go to room 2.
3. From room 2, go to room 4.
4. From room 4, go to room 3.
5. From room 3, go back to room 4.
6. From room 4, go to room 2.
7. From room 2, go back to room 4.
8. From room 4, go to room 3 and a cutscene should be displayed on entering the room.
