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.
