What are Arithmancy Doors in Hogwarts Legacy
Arithmancy Doors can be seen with a blackboard-like surface that is initially blank until you interact with it the first time. Once you interact with it, it won't open and 2 triangle equations will appear for you to solve. Around the door is decorated with a large wooden archway with several discs with figures on them. These doors are quite hard to miss and they are large in size and can be found all over Hogwarts in the different classrooms and halls and such.
How to Find the Arithmancy Number Door Cipher in Hogwarts Legacy
There is a piece of document you can find to help you solve these Arithmancy Door puzzles. Arithmancy Doors can be solved regardless if you are able to find the cipher or not, but it certainly makes solving the Arithmancy Doors easier and quicker.
First off, head to the Divination Classroom Floo Flame located in The Lobrary Annex of Hogwarts. From the Foo Flame, go through the entrance on the right and follow the path of the wooden walkway to reach an intersection with a path to the right. Go right and continue along the path toward the end. There you will find an Arithmancy Door, and across it is a blackboard with illustrations based on the puzzle and a blue box next to it on a bench. Open the box and then you will be able to obtain the Arthmancy Number Door Cipher needed to help solve the equations on the doors.
How to Solve Arithmancy Door Puzzles in Hogwarts Legacy
To solve the mathematical puzzle, we first need to find the solution to a simple mathematical equation that we can observe in each of the pyramids in the center of the puzzle. Each of the vertices of the pyramid represents a number, and the sum of each must result in the number of the center.

How to place the missing figures for the Arithmancy Doors
To place the correct figure we must use your magic wand to activate and move the two mechanisms that are on each of the sides of the great puzzle until you find the correct figure.
Each of these mechanisms corresponds to each equation. The pyramid on the left acts on the first equation, while the mechanism on the right acts on the second of the equations.

These types of puzzles are a unique and exciting feature, that will test your math skills
Mathematic Puzzle
First equation:
The upper pyramid contains the first of the equations. It is the simplest, since we only need to solve what value represents the sign 
3 + 0 + = 5
This means: 3 + 0 + 2 = 5 = 2
The missing figure that represents the number 2 is 
In this case, the missing number is 2, represented by The Graphorn figure.
Second Equation:
The inverted pyramid contains the second of the equations and is somewhat more complex, since in addition to the numbers in the vertices, we also observe a figure of a unicorn. Each figure carved in the frame that surrounds the entire wooden door is equivalent to a number.
4 +

= 12 = 
1 = 7
