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.

This is like asking why it’s wrong to drive on the other side of the road. There’s nothing inherently wrong with it, but everybody already agreed to do it the other way, so you won’t get along well with them doing it your way
