Both 1 and 9 would make sense to me. I don't know which order to do this shit in. Aren't there different schools of thought?

Well, I would have went:

6/2=3
2+1=3
Answer must be 33.

math is exact, there's no room for error on the math's part, only the mathtards.

I swear my brother always tells me that 0.999' = 1.

Then he shows me some clever way of doing it that I never remember until I come to the conclusion that maths is broken.

Spurtung may be a childish dick, but he's correct in the regards of math being exact. There's NO room for 2 answers making sense. There is only 1 correct answer and any other answer is incorrect and irrelevant

en.wikipedia.org/wiki/Order_of_operations

There are alternatives to the standard.

mathdude.quickanddirtytips.com/can-math-problem-have-more-than-one-right-answer.aspx This guy calls himself "the math dude", he says sometimes maths is ambiguous.

Also, I'm fairly sure that the answer to some equations can be 2 answers, (a negative and a positive number) I don't know why I'm fairly sure of this but I seem to be, so I'm going with it.

I don't think many things are as straight forward as "this is always correct, full stop".

The answer is 9. If you look at your wikipedia article, there is a section called Exceptions to the standard.

These exceptions, as wiki has stated, only occur on certain calculators and programs. That does not mean that the actual result changes.


Honestly though, why did you make a thread about math? Every time I've seen one, on any forum, it's lead to massive arguments. No good can come of this thread. I suggest you kill it at once.

that?

you realize it's about finding the two different values of a variable and therefore has nothing to do with this, right?



actually, taking that as example and applying to the OP:
6/2(2+1)
A/B(B+C)

what makes more sense?
A/B*(B+C) or A/(B*(B+C))

It was a response to this. I realise that it is not exactly the same, but it has something to do with 2 answers making sense.

I am no good at maths, this isn't a woe. I can pretty much do addition and subtraction and know my times tables up to twelve, more or less- this seems to serve me adequately enough.

Moral of the story is, if you dont specify whether you mean (6/2)*(2+1) or 6/(2*(2+1)) different calculators will guess what you mean and sometimes give you different answers.

So if you type it in like it is in the OP, you deserve to get it wrong and should learn to use a calculator and mathematical notation correctly. And if a teacher were to put that on a test like that, it is either a trick question or the teacher shouldnt be teaching math.

It's an example of bad mathematical notation; the equivalent of a dangling participle in grammar.

More accurately, it's an ambiguous misuse of notation used to start troll threads every couple of months.

I'm guessing ED is currently on a forum ban, yes?

The right answer is: the question is incomplete.

True math equation will have parentheses on all mathematical problem in order to derive a function in between input and and a set of permissible output.

That, and the word "surd" is all i remember from doing maths at school. If it's a silly word, you can bet i'll remember it.
