every calculator ever solves it the same way and so should you because there's only one answer.
so yes
go take a make-up exam
every calculator solve it the same way because it assumes the person wanted it solved the way it is written.
but maybe the person did not and that's why it's ambiguous.
I'm not saying your answer is wrong, I'm saying it's one of the multiple ways of solving it, doesn't mean the answer is right.
The way many people, including you it seems, were taught order of operations, is wrong.
You don't do multiplication before division and you don't do addition before subtraction.
For every equation with no variables in it (unless you're doing some freaky stuff with negative square roots) there is only 1 correct answer. It only has one answer because the correct way of evaluating it avoids ambiguity by specifying that you do things left to right, and that certain operators have equal precedence.
Yes I know all of this, I'm simply saying the equation is ambigious and PEDMAS gives you a way to solve it without bothering yourself of the ambiguity.
And for my statement that there is multiple ways to solve this I never said they where right I was just saying that because it's ambiguous.
Sorry for causing confusion
