Will H 46 Posted April 16, 2011 I see now how the question is somewhat ambiguous, and it's open to interpretation. Saying that, it is kind of impossible to answer seeing as they don't specify whether they want you to do 48/(2(9+3)) or (48/2)(9+3)... I'd still go with 288 though, seems more logical with BIDMAS.How can math be ambiguous? Its one answer, no matter what. Or else it wouldn't be math. Questions can be ambiguous. Answers and the maths within can't be ambiguous and still be correct, even if the answer is that the question is ambiguous. The mistake here is with the syntax, not the maths itself. We're not destroying the fabric of causality here, we're just saying that the asker should have typed in a goddamn bracket.I still don't see how this question is even remotely ambiguous. There's a reason why PEMDAS/BIDMAS/whatever exists. I don't know how your experience with math went, but I've always been given expressions with the least possible amount of brackets possible. There is a confusion about whether just the 2 is multiplied by the (9+3), or if the whole 48/2 fraction is multiplied by the (9+3). Division and Multiplication occupy the same 'priority', so it's ambiguous even if BIDMAS gets involved. You wouldn't get this problem if it was fully displayed. The best approach with text equations is 'When in doubt, put brackets in to clarify'. You're not going to get any prizes for efficient text equation writing when it causes this amount of confusion. ~ W ~ Share this post Link to post Share on other sites

Will H 46 Posted April 16, 2011 Actually, yeah, you're right about the left-to-right thing, I partially retract that statement. You will get a consistent answer (which is of course 288) if you throw it into a good calculator like Wolfram Alpha, but many humans don't approach questions the same way. A question of BIDMAS only seems to pop up when the whoever's asking the question is being intentionally sloppy and a little big annoying. Blah, I should stop caring about these kinds of things. ~ W ~ Share this post Link to post Share on other sites
