There's a 960 on screen. It's angry, it's TANKY and your minus does 1 damage. You could be here all day. Or you could fire one %80 and watch it solve all your problems.
Modulo replaces a number with the remainder after division. 960 divided by 80 is exactly 12, remainder zero. The bigger numbers in the game are just one good Mod Blast away from nothing, if you can do the math in your head.
Modulo is one of the strongest operators in the game and that's fine, because its power lives in your head.
