Sometimes 1+1 is 2, like when you’re counting stuff.
Sometimes 1+1 is 1, like when you just need a Boolean indicator of whether something is true. Pressing the elevator button multiple times should behave the same way as pressing the elevator button once. Planning out a delivery route requires a stop at every place with at least one item to be delivered, but the route itself doesn’t change when a second or third item is added to that stop.
Sometimes 1+1 is 0, like when dealing with certain types of rotations, toggle switches, etc. Doing a 180° rotation twice is the same as doing it zero times. Same with doing a reflection transformation twice.

Tell that to Factorio, Satisfactory, and Dyson Sphere Program players.

Hey, we still follow this principle. It’s just that the scope is “an entire planet” and the only limiter is my prescription of Ritalin.
