This question already has an answer here:
I saw this photo on my social network.
The ambiguous expression $6\div2\times3$ yielded 2 different answers.
The difference is the order of operations. If the division's done first then the answer is 9. If the multiplication was first then the answer would be 1.
What is correct?
There are rules for the order of operations like "BODMAS" for example (I use it) but it doesn't say what is correct in such situation.
Is it possible that both answers are correct unless "brackets" are specified? Or is there one correct answer? Is there a rule for the "direction" in which those must be done? "left to right" for example?
edit: It looks like it's known that it should be done from left to right but the question now is whether:
It's just a convention.
It's a definite rule that makes us say that one of the answers is wrong.
tag should be "operator-precedence" for example. Help me with the tag please :)
