originally written in Feather (found here: https://codeberg.org/MineTurte/Feather/) I decided it was super simple and could easily be remade in scratch, so I did just that. Takes an operation and evaluates it. Like 5+5*2. Except this evaluator is stupid and doesn't know what the order of operations is. So while traditionally 5+5*2 would equal 15, here it equals 20. Set speed to 0 for instant. Only supports + - * / not parenthesis
