So the answer is nine. I need to make sure so when I help my kids with their homework I dont contribute to them getting D's n F's...lol

I don't care who you are, that's funny!

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.

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 '

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

Simple math...

Because of the parentheses, 6

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.

The answer is 9.
 
I think we will get the next Android OS (Ice Cream Sandwich) before this math issue is settled... :)
 
Not mathematically.
Noone's showing any math working out that

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

2(1+2)

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.

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
 
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 :)

Can't believe there is SO MUCH about this on the net!

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.
