What makes non-PEMDAS answers invalid?
It seems to me that even the non-PEMDAS answer to an equation is logical since it fits together either way. If someone could show a non-PEMDAS answer being mathematically invalid then I’d appreciate it.
My teachers never really explained why, they just told us “This is how you do it” and never elaborated.

Also something a lot of people forget/dont know, multiplication and division have the same priority so they could be swapped, same with addition and subtraction.
Edit: since there apparently is some confusion, by swapped I mean PEMDAS and PEDMSA are equivalent.
