Sigh.

You do not multiply with Roze - you add with Usta, then I multiply the outcome, all to be divided by Roze.

Uh oh. Roze is being divisive!

I was wondering if this problem was designed to isolate left-brainers from right-brainers, but the roughly 50/50 split seems to indicate otherwise. But for sure, our viewpoint (whether correct or not) says something about our personalities and how we see the world.

WTH! lol when you start using people in the equation...that means we're moving on from the question at hand.

but hmm....
so if EM and Roze are equal (both being mods), we are basically negated in the equation so...

If we are following PEDMAS, that means dan + usta = novox

I kept thinking of dan's assertions - and it hit me what you were saying:

Quote:
 EarlyMon/Rose(dan330+usta)=nova777 (imo)
So - that's the same as:

EarlyMon*dan330 + EarlyMon*Usta = novox77 * Roze (imo)

So, if novox77 and Roze multiplied (imo), the result might be confused - very confused.

Schizophrenic even.

And what about that (imo)? Is that putting on the dog? Or just its house?

I'm just glad it wasn't a cat - we'd never know where he was.

Jeez - calling dan one usta shy of a novox was pretty personal there!

You left out the (imo) -

dan330 + Usta = novox77 (imo)

And that's only presuming we're equal (both being mods).

I think the real reason you factored us out with that sleight of hand was because you didn't want people to see you under me. *cough*

Only when it's sunny or dark, Roze, only when it's sunny or dark.

Kinda makes the solution obvious.

(Copied from Yahoo questions) Just felt like adding fuel to the fire.

I am your college professor that you requested, with a doctorate in Mathematics. I will break this down as simply as possible and end this debate as approx. 10 students have already asked me this today.
The problem as it is written is 6÷2(1+2) , the ÷ cannot be substituted with a fraction bar because they have different ranks on the order of operations. It is an illegal math move to do this. The bar ranks with parentheses, ÷ is interchangeable with *. therefore the problem must be solved as 6÷2(1+2) NOT 6 (over) 2(1+2) we do the parentheses first, so 6÷2(3), the parentheses are now no longer relevant, because the number inside is in it's simplest form. Every single number has implied parentheses around it.
6÷2(3)
(6) ÷(2)(3)
6÷2*3,
or even converting the division to multiplication by a reciprocal (a legal math move)
(6)(1 (over) 2)(3)
are all correct ways to write this problem and mean exactly the same thing. Using pemdas, where md and as are interchangeable, we work from left to right, so (3)(3) or
3*3= 9

Just because something is implied rather than written does not give it any special rank in the order of operations.

The problem in it's simplest form, with nothing implied would look like this:
(1+1+1+1+1+1 (over) 1) ÷ (1+1 (over) 1) * ((1(over) 1) + (1+1 (over) 1))
From here, nothing is implied, This again, works out to 9.

If the symbol '/' was used this whole debate would be ambiguous since that symbol can mean "to divide by" or it could mean a fraction bar.

HOWEVER, because the ÷ symbol is used, it can not be changed to mean a fraction bar because that would change the order of operations and thus the whole problem, you can't change a symbol to mean something because you want to, in doing so you are changing the problem.

Once and for all, the answer is 9.

Hopefully some of my students see this so I can stop answering this question.

End of debate... hopefully.

Welcome windowshade! I've seen several emails from math professors that solved the problem and they all say 9 (if none of them are photoshopped... but that would be a bit extreme). I'll see if I can try to dig them up because I saw them in the many posts on Facebook.

I do agree with the poster that it would be different if the symbol was '/' instead of '÷', which I believe is the source of the confusion. I've come across so many people who believe that it simply means "over"... but that would be puzzling because if you say it's "over" in this case, what would stop it from meaning over in this case:

9÷3+6*3 meaning 9/3+6*3

In what cases would it mean to "divide" and in what cases would it mean "over" if we treat the ÷ symbol as just "over" in 6÷2(1+3)? The D in PEDMAS would be meaningless. hehe

I just cast my vote and wow it is closer than I thought on this forum site. lol How amusing this simple problem can cause such a ruckus.

My calc teacher back in high school did calc for fun... We teased him about it and he didn't care. lol He also did a lot of stats for some website to make extra money. I forgot what he was doing exactly but I know he made a good amount of money.

My high school calc teacher was the same way. He's famous for having started the Math Club at our highschool when he was a student.

Must be something inherent to highschool calc teachers, eh?

Gee.. why do you think they became math teachers? To pass on their love of math to the students. I find the teachers I had that were passionate about what they were teaching were the best teachers.

Thank you all for this wonderful math discussion. I thought I understood math before this thread. Anyway, it seems to me that the answer has to be 9.

Givens:
1. PEDMAS is correct
2. PEDMAS = PEMDSA (as a Randian Objctivist I assert that division and multiplication have equal standings in the order of operations and cannot at the same time be unequal due to someone creating a mnemonic.)
3. The person who posed this question knew enough about math to understand the logic problems this would cause mathletes.
4. With point 3 stipulated, the original author could have written this problem as 6/2(1+2), but didn't for a reason. (for some reason I can't stop thinking of Vizzini arguing with himself over which goblet of iocane laced wine he should drink for the Dread Pirate Roberts)

Therefore, we have :
6 divided by 2(3) (I just spent 3 minutes looking for the divided by symbol on my keyboard without success)

3(3)

9

BTW, after being out of high school for over 20 years I am taking my math placement tests for college on Tuesday. I do not have the math background that some on this board have, but hopefully I'll be computer engineer in a few years. This tread is certainly thought provoking.

I agree... but sometimes... they can be a bit too passionate. lol One of my linguistics professors would often go on big tangents if he was on a "roll". lol It usually ended up with him trying to explain things with terms that we haven't even heard of before. He definitely knows his stuff though!

I was taught that a number next to parenthesis means nothing more than a multiplication sign. Therefore, 6 / 2(3) reads 6 / 2 * 3 = 9.

Anyone who says do order of operations and gets the answer 1 is simply mistaken for what the P in PEMDAS means. It means do what is INSIDE the parenthesis, not multiply what is on the outside by what is on the inside.

I do agree with the poster that it would be different if the symbol was '/' instead of '÷', which I believe is the source of the confusion. I've come across so many people who believe that it simply means "over"... but that would be puzzling because if you say it's "over" in this case, what would stop it from meaning over in this case: 9÷3+6*3 meaning 9/3+6*3 In what cases would it mean to "divide" and in what cases would it mean "over" if we treat the ÷ symbol as just "over" in 6÷2(1+3)? The D in PEDMAS would be meaningless. hehe I just cast my vote and wow it is closer than I thought on this forum site. lol How amusing this simple problem can cause such a ruckus.
There isnt any difference between ÷ and /. They both simply create a fraction. if there is no parenthesis in the denominator, then it is only that single number in the denominator. 6÷2(1+2) = 6/2 * (1+2)

I can't believe this is still floating around...it's 1.

Simple math...

Because of the parentheses, 6÷2(1+2) is:

This is starting to look like one of those 0.99... = 1 threads. Also, my stellar (I can't believe I just said that) intelligence says the answer is 9.

So...mathematically.... How'd you separate the '2' from the '(1+2)'
As in the attachment, if you separate the '2' from the '(1+2)', I don't think 9 is your answer.
.
I dunno... even kAlgebra under Linux gives answer as 1.

Good problem, though!

My earlier posts covered how this is was a compiler and tool issue.

SO, mathematically, how'd ya separate the 2 from (1+2) ?

Following others logic...

6÷2(1+2)

6÷2(3)

Then some want to jump out and make it
3(3)

But why is the parentheses being ignored?

It should be

6÷2(1+2)
6÷2(3)
6÷6
=
1

I'd like to know why everyone is just ignoring the parentheses.

If you said
6÷2x(1+2)

That goes to 6÷2x(3)
which gives 3x(3)
which gives 9.

People are IGNORING the parentheses, which takes precedence, PEMDAS.

That means do what's inside the parens, that is all. That the 2 touches it only means *.

I have.

And while I see 6÷2x(1+2)= 9

I don't see 6÷2(1+2) = 9.

6÷2(1+2)

is

6
--------
2(1+2)

So how does that solve to 9?

6
------
2(3)

6
----- = 1
6

Now, as I've said, if you said 6÷2x(1+2)

that would be

6
---- (1+2)
2

which works out to

6
---- (3)
2

which works out to

3(3) = 9

I think we will get the next Android OS (Ice Cream Sandwich) before this math issue is settled...

It was settled long ago.

Wanting a thing does not make it so.

Not mathematically.
Noone's showing any math working out that

6
-----
2(1+2)

equals 9

Who knows - maybe it's NewMath

BUT!

I guarantee we'll settle this before Moto unlocks the Atrix bootloader

UPDATE: All I want to see is the math worked out.

I just want someone, ANYONE, to show me how

6
----
2(1+2)

is equal to 9

look at it this way. Car inventory.

ya got 6 cars on an available-for-sale list.
your total available cars divided my inventories cars SHOULD = 1, or you got math issues.

so using that, I have a list saying I have a total of 6 cars available available for sale.
I have 2 lots, each with 1 new car, and 2 used cars.

6÷2(1+2) = 1

?

Maybe as a word problem it's seen better.

Anything other than 1, and either my list is off, or my lot inventories are off.

You'll settle it when you read the thread, not skim it, and stop repeating yourself.

Because that's an incorrect representation of the original problem. You cant just move the 2+1 to the denomainator just because a 2 is multiplied to it.

That would be like saying:

1
___ = 2+1
2+1

Which is clearly wrong.

Everyone who comes up with 1 for the answer has to multiply the two next even though that isn't correct in the order of operations, because they "see" the problem in their minds as 6÷(2(1+2)) which puts in new parenthesis and changes the problem. Adding an x just further changes the problem by introducing a new variable heh.

I think it just come down to the fact that there were two incorrect assumtions people were making:

1) "Being next to a parenthisis has special meaning" in math.

2) or "division automatically implies everything that comes after it ends up in the denominator."

Neither of which are true.

I dont know if reading it that way helps people make any more sense of it ...but it's fun to try!

I have read the thread, even followed the links, even to the one where someone links to google, and the formula gets obfuscated to (6/2)*(1+2) which is NOT the original expression...

Then there was the detour about functions...

Oh - and I STILL say this will be settled before the Atrix bootloader issue is

googling " 6÷2(1+2)" brings up some funny stuff - and some answers wackier than 1 or 9!!!

The expression 2(1+2) has not the special property you ascribe. The P in PEDMAS stops at the parens insides.

You got a Ph.D. in math saying it, in physics, a doctoral candidate saying it, and finally Wikipedia.

Your opinion of the evaluation is incorrect.

Wait, so did we settle that it was 1 or 9? My brain imploded at 6÷2(1+2) = ?

I dunno - seems people are trying to imply that 2(x+y) is no longer the same as 2x+2y.

when you type that formula into google, it automagically ADDS parentheses, and THEN declares it's 9!
They translate it to
(6 ÷ 2) * (1 + 2) = 9

NewMath, I tell ya.
NewMath.

PLEASE stop trolling. Sarcasm is pointless, this has been covered.

 Android Forums 6÷2(1+2) = ?
