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.

In essence, it’s done for simplicity sake. It’s just something everyone can agree on, it could have easily been DEPSAM or some other abbreviation. However, think about it like this, exponentiation is repeated multiplication, multiplication is repeated addition, and addition is just counting up. It’s placed in the order of highest influence, but is still just done to create uniformity.
