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?

    When you get to doing division and multiplication, it can make sense to look at what is being done to what and see if operations cancel out or simplify. E.g. if you are multiplying by 6 and dividing by 2 and bother operations are going to affect the same number/group/etc. there is no need to do both operations, you just multiply by 3 since that’s ultimately what you are doing. Really, any place you can simplify operations, do that. Same goes for addition/subtraction. The Commutative Property is really handy for making hard math easier.
