Someone made a working calculator in Super Mario Maker

A numbers game.

An ingenious Super Mario Maker fan has constructed a working calculator from Nintendo's level-building creation kit.

Dubbed The Cluttered Chaos-Calculator (ID: 705C-0000-01B3-FE78), the complex stage allows you to add two numbers between zero and seven.

I can't even begin to describe how the stage's Rube Goldberg-esque contraption calculates this numerical wizardry, but the level's creator Helgefan offered a complex explanation as to its inner working on Reddit.

All you need to know is that you ascend one of eight columns, each labelled with a number constructed out of clouds. Then, you ascend a second column based on which number you choose to add. After a brief intermission offering the instruction "don't move", you head down a warp pipe and stand still as the confounding concoction of shells, switches, traps, and conveyer belts work in harmony to tackle your simple arithmetical query. Finally, at the end, a sum is presented.

Check out YouTuber Robin T's video above to watch The Cluttered Chaos-Calculator add six and six together.
