This one has been beat to death.
I'm sticking with 9
brackets first
then both M and D, LEFT TO RIGHT
That said, the presentation is the problem. Not the answer.
So, do I mean the answer is not the problem or the presentation is not the answer?
The PEMDAS system has been mis-taught in some schools for a couple decades now. Even math teachers will argue of order of operations because the centuries long held, scientific method, which is what I described, involves eliminating the paraphrases first, which is what is used in the sciences. Reason being is 2(2+1) stays 2(3) until you do so. 2(3) is equal to 2x3. This is the same as if you were solving for x, and 2x, where the number in front is multiplying what is in the phases. The scientific method states that you solve inside the Paraphases, then any Paraphases Exponents and then any Multiplication/Division of the Paraphases then moving on to Multiplication, Division,Addition,Subtraction. Which is why "Scientific" calculators will give you a different answer than a Algebraic/Graphing calculator.
So the problem is that there's two sides arguing over the "correct" order of operation, thus the teaching of two different methods.
