At the very beginning, you are asked to choose two numbers from 0 to 9, and then decide whether to add them or subtract the second from the first. At this point, the game really feels like a regular platform game.
The most interesting thing begins after that - after hitting the pipe, the player needs to stand still and not press anything for several minutes. Moving blocks move Mario to the final point, and along the way he passes a bunch of dangers, mushrooms, blocks and all sorts of traps - all this looks like the mechanism of an intricate calculating machine. And at the end, the bombs explode in such a way that only a number remains - the same one that should have been obtained in the process of addition or subtraction.
You can find the level by the code C81-8H4-RGG. Helgefan also created the calculator in the first Super Mario Maker, but then there were fewer numbers, and the level design was not so pretentious.
