6/2(1+2)

[Makο]

I've been seeing a lot of these threads on the Flood.


Through PEMDAS, it's obviously 9. And yet, some people continue to argue that the answer it different, like 1 or something.


Is there some meme or thing that I am missing involving this?

[.Nu-13]

People who argue that the result is different than 9 are stupid :/ It's elementary knowledge

[Βyakuya]

6/2(1+2)? In my opinion, you do whatevers in the parentheses, and then multiply it by the number next to it.

So First: 6/2(3)

And then: 6/6

And you get 1. Jeez this is basic math . Multiplication comes before Division according to PEMDAS. And that's that.


...So what else to talk about?

lol@above post

Yes, up to the 6/2(3) is right. So it's technically 6/2*3. Dividign and multiplying are on the same prority level, so you do them in order they are. So it's

6/2=3
3*3=9

simpler math

It all depends if you mean the (1+2) is multiplied by the WHOLE thing or if its in the denominator.

(6/2) x (1+2) = 9

OR

6/(2x(1+2)) = 1


^Pick which one you mean.


This thread is full of idiots.

6/2(1+2).


On the second one, where does the extra parenthesis come from? Division and Multiplication are on the same level, therefore there is no reason to add those parenthesis.

Equations only have 1 answer. Anything that doesn't simply isn't an equation.

The way you have it written could be interpreted [b]2[/b] different ways.

1. (6/2) x (1+2) = 9

The (1+2) is not in the denominator, and therefore you will multiply by 3.

6/2(1+2)

3 x (1+2)

3 x 3 = 9



2. 6/(2x(1+2)) = 1

The (1+2) IS in the denominator, thus you will multiply by 1/3.

6/2(1+2)

6/(2x3)

6/6 = 1



@underlined: Quadratic Formula sometimes gives multiple solutions to one equation. =/

[Cloister]

Parenthesis > multiplication/division.

9.

[Yasu]

6/2(1+2) = 6/2(3) = 3(3) = 9

Don't take it too seriously.
Knowing where it comes from...

[~The Dark one~]

it is 1 because

Parenthesis (1+2)=3
exponents
multiplication 2(3)= 6
Division 6/6=1
Addition
Subtraction

Go back to primary school

For f***'s sake, multiplication/division are on the same f***ing level, so you do them in order they're in equation

[Tourmaline]

We use BEDMAS, here. Brackets, Exponents, Division, Multiplication, Addition and Subtraction, but it is the same thing, either way.

6/2(1+2)
6/2(3)
3^3
9

It would be nine no matter what. Especially how you wrote the question out, TC. Was the first 2 in a closing bracket as well, then the answer could be 1, but it isn't, so saying the answer could be 1 is absolutely wrong.

Legend Zero simply miswrote in example two, assuming it was to answer this question, but it wasn't. Since when do we get to change how a question is worded? His second example could not apply to this question, but I understood he showed it as an explanation for the people that don't know mathematics.

[Tentacruel]

It's both 1 and 9 because the dumbass who thought of it in the first place didn't clarify the order of operations.

[.Starrk]

Simple. People think the answer is 1 because they didn't listen in class.

We can assume it's the ladder since they'd probably of put "6/(2(1+2))" if the former was intended.

[BehindTheMask]

Its 7.

6/2(1+2)
6/2+4

You don't assume in math....you want the [i]right[/i] answer. How come nobody else can see that the problem can be worked 2 ways?

Opinion is worthless when it comes to math. What you are doing is incorrect.

I honestly think you are overcomplicating this for no reason.

If the question was posed as [i]6/(2(1+2))[/i], the answer would be 1, because you would first add the one and the two, multiply by the two, and divide six by your result of the previous two steps.

However, because there were no brackets around the "denominator", the questioned is [b]assumed[/b] to mean (6/2)(1+2), because by order of operations, you must add the one and the two first (which does nothing), and then immediately divide the six by the two. However, the reason this is ambigious online is because of the slash. In normal mathematics, one shows division by placing a bar between the numerator and the denominator. Depending on whether the bar encompasses the (1+2) in the denominator affects the final outcome.

Regardless, the way the question was posed is retarded anyways. If one wanted to make sure the answer is one, you would write it (as said before) as [i]6/(2(1+2))[/i], and if one wanted to make sure the answer is nine, you would write it as [i](6/2)(2+1)[/i]. The culprit of this retardism is the "slash" which we falsely define to be division, as it creates a degree of ambiguity which we cannot determine.

Either way, if you are following normal PEMDAS or BEMDAS, the answer [b]is[/b] nine. If you are looking at it differently, you are assuming the question is written differently than stated.

[Şäŗôķů]

According to BehindTheMask 1 + 2 = 4. But anyways it's 9.

Parenthesis
Exponents
Divsion/Multiplcations (whichever comes first from left to right)
Addition/Subtraction(whichever comes first from left to right)

[Static]

You're all right, except BTH, who is very wrong. Only in variable equations can we multiply in the 2.

It totally depends though.

6 / 2(1+2) = 1

6/2 * (1+2) = 9

There is no clear way to tell what the implication is though, you can't just presume that it is 9 because the 6/2 comes before the 2(1+2).

I agree with you up to this point. You would be left with

6/2*3


Now, as stated, this is the problem spot. You say that you automatically divide the 6 and 2, but order of operations lets you multiply or divide in any order. So one doesn't assume the question is written differently, instead that they prefer to multiply before dividing.

tl;dr: We both agree that TC is an idiot.

To be fair, it was stated that mathematics is read from left to right, so when you see something such as 6/2(3), the default is to say that the 6/2 must be the first operation done. Again, because we are not sure what the slash encompasses and what it doesn't, we are required to assume that it is read standard left-to-right, and all "MD" in "PEMDAS" is done first [i]from left to right[/i], even if the answer of nine was against the author's intentions.

[i]Now, as stated, this is the problem spot.[/i]

No, it really isn't. I hate using this terrible analogy, but punch in [i]6 / 2 * 3[/i] on your calculator, and you will get nine. Just because the three is in brackets doesn't give it any special superpowers. The question was phrased terribly, yes, but the answer is still nine. The ambiguity doesn't change the answer or make two answers, it just makes the correct answer harder to locate.

By saying the answer is one, you are [b]assuming[/b] that the two and the three are both part of the denominator, and that may not be the case. You should be reading it, like PEMDAS states, from left to right, and doing whatever MD comes first, from left to right. The 6/2 comes first, which is three, and then 3*3 comes next, which is 9.
