Want to play a game?

I found this on facebook

Lots of people have differing opinions.

There are a LOT of deceptive people out there who like to play that game. It's just a riddle to trick those who are not certain of what they already know. In other words: They're lying to you.

This is not the first time this exact question (although with different examples) has come up on this site. Pay no attention to the gameplayers who like to sow confusion and frustration; you'll only make things more difficult for yourself. You know the answer--do not let them take your certainty away. Deny ignorance....

I understand how it works but it just doesn't look right to me to divide then multiply because it goes against PEMDAS.

You can do multiplication and division the same time, just like you can do adding and subtracting the same time. But go left to right.

The parenthesis are done first (1+2) which equals 3.
Then, since there are no exponents you would move on to 6/2. Though in the acronym PEMDAS multiplication comes first, in the equation division comes first, and in any form of math when dealing only with division and multiplication you do the problem from left to right. Thus you are left with 6/2 (which is 3) times 3, which gives you an answer of 9.

Ah. Thanks, Bigfoot. That's what I should have said...

Anytime my friend. People need to stop looking so hard at the equation and just do it.

multiplication and division have the same priority, so when all that is left is * and /, you go left to right. 9 is the correct answer.

Yes. Another correct way of expressing the rule. This is the part that's ignored by the gameplayers in order to fool the unwary....

I've heard of the dumbing-down of American education, but dear God, what are they teaching in schools these days? Order of operations should be the first thing on the plate. There is no answer but 9. Now, understanding that 9 is the answer, figure out how that comes about and reject any other logic. And never use that logic again--for this problem or any other....

Right. Forget about the numbers. It's always about the order of operations.

Guys, I got the answer lol

The problem is poorly written! It's the main reason why there's so much ambiguity present and different interpretations have arisen.

Even when you type this into a calculator you'll get a different answer, depending on the model.

Replace the word written with the word understood.

I will go with 1, and you can blame the Canadian public education system on this one! They taught us BEDMAS , or Brackets Exponents Division Multiplication and Subtraction. So, I don't know, maybe I should have gone to private schools?

That is all anyone had to say...

Here is one for you: What size diameter circle (Regardless of increment of measure) has the same numerical linear circumfrence as it does area? (Excluding the square aspect, the number(s) are the same). It's simplier than it seems.

It's 9, and I can't believe people don't understand order of operation. How do you debate it? It's a right and wrong question.

You also go left to right, if that helps.

Oh, and when there is no operation to sort out in between the parenthesis, you can treat is as multiplication.

edit on 12-6-2012 by satron because: (no reason given)

Order of operation is simple sir.

Do what's inside the parenthesis first ALWAYS.

Easy equation and most are taught this freshman year of HS.


Th answer is 9.

I'm kinda surprised anyone struggled with this. I've lost a lot of my advanced math skills, granted, but this is basic stuff, your grade 3 student should be able to do this.

"brackets" first.

1+2 = 3

which changes the equation to:

6/2 [x] (3)

now this is where I guess I break the rule, cause I change it to:

3 (3)

meaning I do the division of the number outside the brackets before multiplying it against the sum inside the brackets, which technically breaks the rule.

But not really, because 6/2 and 3 are the same thing, and it's far easier to multiple 3 x 3 than 6/2 x 3, because in reality, however you do it, the sum is 3, so use 3. It's not really breaking the rules honest

Shoot, thought we were talking about War Games.

*walks out of the thread*

Is anyone disturbed by the fact members are passing this EXTREMELY simple math problem off with the answer of

"Eh maths not my strong suit."

Seriously... basic... simple... math...

Or worse yet people are actually coming up with the wrong answer for this?!

Lol don't blame BEDMAS! If you follow BEDMAS, it will take you to 9. Remember... when there are no brackets or exponents, division/multiplication go first (in order of appearance from left to right), followed by addition/subtraction (in order of appearance from left to right).

No private schools needed. We kept it real in public school... but not always classy

i'm old school so i kinda needed the problem to look like this:
6/2 'X'(1=2= 9 !!!
didn't realize without the 'X' there,you treat it like its there any way!

I'm shocked this is a debate. Some replies feel like the work of trolls. BEDMAS got me to the answer in seconds and I almost failed grade 11 math. Anyone who did not get the answer 9 needs to go back to school, or get ther 13 yr old to explain it to them.

A sign of grouping can be omitted when it contains only a single number.

Unless it's otherwise stated, consider it multiplication.

3(3) = 3 x 3

*6/2(3) is the same as 6/2 x 3*
