If you don't accept adding and subtracting numbers as allowed mathematical transactions, multiplication doesn't make sense at all. It isn't arbitrary. It's fundamental basic accounting.

Pemdas is mostly just factoring, kinda. That's how you should think of it.
2x4 is really 2+2+2+2.
That first 2+(anything else) can't be acted/operated upon until you've resolved more nested operations down to a comparable level.
That's it. It's not arbitrary. It's not magic. It's just doing similar actions at the same time in a meaningful way. It's just factoring the activities.
Compost them first then you can eat the rich while also being vegan = Billions and billions of carbons.
