What math operation order do you use? (lemmy.world)

I have seen several people saying the order operation is

Brackets/Parenthesis
Orders (roots and powers)
Divisions
Multiplications
Subtractions
Additions

But I was taught it as

Brackets/Parenthesis
Roots and powers, left to right (independently of the exact operation)
Divisions and multiplications, left to right (independently of the exact operation)
Subtractions and additions, left to right (independently of the exact operation)

So, what order were you taught and/or use today?

I've seen this topic come up for the second time this week. i'm an engineer, so I've been trained to use maths as a tool extensively. But to be honest, I couldn't even tell you. I don't remember specific rules for it, I just do it without even thinking about it anymore.

Its only ever a problem when people post up ambiguous equations and use sock-puppet accounts to call every answer stupid and wrong until a huge fight erupts.
