BODMAS as taught in Europe is the same but just clearer. Brackets first, Orders, Division, Multiplication, Addition and Subtraction. All in that order.

So

Brackets (2+1), and inside there’s just Addition, so now (3)

Division 6/2 =3

multiplication 3*3

= 9

If you were to apply PEMDAS in the same way, you’d end up with Multiplication before Division, and result of 1, but that’s not how PEMDAS works, as I understand it (not being American). Thus the confusion. BODMAS is just clearer.

The above arguments on maths texts are fine, but don’t correlate to basic BODMAS teachings in primary schools. Ask any kid who knows BODMAS and they’ll give you 9. They are unlikely to know a fractional calculus approach. Many computers and calculators follow the same convention, hence 9. Here’s one based on teaching BODMAS to kids, result… 9 http://www.mathsisfun.com/algebra/operations-order-calculator.html?i=6%2F2(2%2B1)

And there’s the word, convention. 9 or 1, the answers are both right or wrong depending on convention.
