Arithmancy doors are like algebra equations, with animal symbols and question marks in place of x and y variables. All three numbers outside a triangle should add up to the large number in the center. At times you'll see an animal symbol outside of a triangle. These symbols all represent a number from zero to nine. They are helpfully shown in order around each door from left to right. You can also refer to the image above as a guide.

For example, let's say you came across a door with this Triangle puzzle: the outside corners show a 2, a spider, and a ? symbol. The number in the center is fourteen. A spider symbol represents the number eight, and eight plus two is ten. To add up to fourteen, the ? would need to be four. You would then find the ? tile nearby the door, and rotate it to the corresponding animal symbol. In this imaginary case, four is represented by the Bird Symbol.
