I'm not sure how to solve these. I opened one by pure luck but I don't understand?

So from left to right. Each of the creatures on the arch around the door represent a number starting from 0 to 9

The big number in the middle of each triangle is the number you need the two smaller numbers and one unknown number to add up to

So for the top triangle, you add tge number that the Tunespoor represents which is 3, to the number 2 to get 5.

Then you need the difference between 5 and 9 which is 4

So you then go to the corresponding wheel (the upright triangle one) and turn the dial to the correct beast that represents 4, which is the Fwooper.

Then use the same method on the inverted triangle using its numbers and turn the corresponding wheel and you’ll unlock the door

Once u got that each figure has a number, starting from 0, then you just have to do the math. So you don't have to keep looking that sheet I mean.
