100 Doors Classic Escape Level 63 Walkthrough

100 Doors Classic Escape Level 63 Guide:
Count the X's and Y's by the door: three X, five Y.
This means X = 3 and Y = 5.

Plug in the numbers and find the difference between the answer shown above the door, and the actual answer:
2(3)+5(5) = 6+25 = 31, difference of 4.
5(3)+2(5) = 15+10 = 25, difference of 9.
2(3)^2-3(5) = 18-15 = 3, difference of 12.

The differences give you the code: 4912.
