There is however a third possible answer. If we are to distribute the parenthetical and not solve, since doing so would be addition, which comes later in the order of operations, we would get the following.
48/2(9+3)=
Everything is the same as the previous example in this step, however, once distribution occurs we are left with two monomials that are not joined by a parenthesis
48/18+6=
Now, if we are to follow the order of operations, we divide first and then add.
2.6666+6=
8.6666
In theory, none of these answers are wrong, but it's a sure shot that someone who is just learning PEMDAS, will get 288, assuming they know nothing about distribution. Someone else who has already been exposed to the other method of distribution, will get 2. And those others who were taught that once unlike terms are distributed, the parenthesis is dissolved, will arrive at 8.6666

what's the issue, divide first or multiply first?
multiply first: 48 / (2*(9+3)) = 2
divide first: (48/2) * (9+3) = 288
the way the problem is written it's ambiguous. whatever operation you do first determines what answer you get

Good thing I only tried it on 1 calculatorOriginally Posted by Russ tha G
^ First post shows four calculators of different types with both answers though.
