the answer is 1

us the PEMDAS system
parenthesis, exponents, multiplication, division, addition, and subtraction.

If we go in that order, we get 1=2, which equals 3. We then multiply 2 and 3 to get 6, which divided by 6 gives us 1.

So lets go over why this is wrong and why this clickbait meme shit is so successful at garnering replies/social media hype.

The answer is indeed 9,
why? Isn't there the PEMDAS system as a basis?

Yes, but MD and AS are of equal weight, so in mathematics we say that whichever comes first from left to right, then gets precedence over the other.
so
6 / 2(1+2) $ we do parenthesis first
6 / 2(3) $ Now starting from left to right
6/2 => 3
3(3) => 9

Because the problem is so simple, most people will rush and forget the little left to right rule, and then we see a ton of people screaming 1 and another group screaming 9, thus creating stupid little fucking arguments. Stop contributing to clickbait bullshit

Both Bednar and pemdas apply in every equation.
PEMDAS = parentheses, exponents, multiplication and division, finally addition and subtraction. Notice how I wrote it out and note the word "and" vs "then". So the problem would be done as

6÷2(2+1)= ?
6÷2 (3) =?
3 (3) =9
The answer is 9.

>>
>>700612929

Holy shit this place is retarded if you are actually saying 1. You all are massively confused by the division sign and/or spacing.

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

You start with parenthesis and then go from left to right once the parenthesis is executed. You all could try learning infix, prefix, and postfix and maybe order of operations will be less challenging.

Pathetic

My biggest issue with this point, is that in this situation 6 is equivalent to 2(3). So 6/6 should be equivalent to 6/2(3). But one of these if obviously 1, and according to you, the other is 9.

Ok, but once the parenthesis is executed, it's not like they disappear. It wouldn't make sense for the number to just be floating there with no course of action enacted. The parenthesis still surround the 3, which turns it into 2 x 3, which equals 6. You then do the division, which equals 1.

Mathematics is the full word. Math is correct since it is a shorthanded version of the word mathematics.

MATHematics makes sense since it is a reduction down to the first four letters of the word.

MATH(s)ematics makes none since there is an additional or repartitioned "s" being spliced onto the shorthand of "mathematics".

>>700616220
Though, even then the times operator should he given... 6/(2*(1+2))
>>
>>700615970

They don't disapeer. They surround the 3, and after executing the division, the 3 is multiplied by the 3 in the brackets.
>>
>>700615823
2(3) is equivalent to 6
but the operation that is done is 2 * 3
therefore the problem becomes
6 / 2 * 3
then again, left to right
6/2 => 3
and you're left with 3 * 3.

Just because something is next to parenthesis does not mean that you do what is outside them first, only the inside.
>>
>>700616293
>Trusting a calculator
smh
>>
>>700615970

What the hell is the logic here?...

Yes, once the operations within the parenthesis are executed, it simply becomes a number. Then you follow order of operations from left to right because division and multiplication have the same precedence.

You can explore this by using a stack method to execute reverse polish notation expressions, postfix, if you don't believe me.

Show your order with symbols because your explanation makes no sense

Anything with a variable introduced is algebra. He just got rid of the x for two steps and then threw it back in at the end.

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

Yeah give him a gold star for making up a method with no logic progression

f(x) = 6 / 2 ( 1 + 2) = g'(x)

f(g'(x))= 9

oh wait that method actually still made more sense ill try again

6 / 2 ( 1 + 2) = x
40 = 40
40 = 40
40 = 40
40 = 40
40 = 40

At least when I was taught PEMDAS I was told to do them in pairs left to right.
(pe)(md)(as)
Parentheses, Exponents from left to right.
Multiplication, Division from left to right.
Addition, Subtraction from left to right.

Boys boys boys... Listen ya fuckin tards yes BRACKETS/PARENTHESIS are the first letter of PEDMAS or BEDMAS. But here's the thing! That means you do the stuff IN the brackets first!!! :O imagine that. So what we end up with is 6/2(3) . Now, is 3 a part of the bracket with 2? Of course not! So what do we get??? 3(3) and you all know what that gives us! That's right, fucking 9.

Yeah but I also built a pyramid as one of my projects back in high school.
It was in year 7.
Seven has 5 letters in it.
7 x 5 = 35
35 divided by the number of corners on a pyramid = 35/4
During that time my father was 55 years old.
55 divided by the number of brothers I have is 55/2
55/2 divided by 35/4 = 3.14
The answer is pi

You are mostly correct, but this equation is ambiguous. It is written poorly.

The division sign used in this equation is not used in higher maths because of the ambiguity.

We don't know if the 6 is being divided by the 2, or if the 2(3) is meant to be the denominator.

Both 1 and 9 are correct in this situation because of the ambiguity of the symbol used here to represent division.
>>
>>700623656
>changing the order like a nigger.
9 is correct
>>
>>700624048
Almost forgot another explanation.

The 2(1+2) can be simplified using the distribution rule as: (2*1 + 2*2)

In this case you get 6/ (2+4)

This would yield 1.
>>
>>700624378
Where the fuck did you learn math? Order of operations. Grouping symbols first, so it's always 1+2 first.
Exponentials next, None. Multiplication and division side by side in whatever order comes first in the equation written. 6/2 is next. That leaves three times three, which then results in the answer of 9. 9 is the only answer.
>>
>>700624378
Wrong.
>>
>>700625003
3 + 8[3 + 2^3 - (5 + 3)]
Now, adding on to teach /b/ mathematics, Here is another example. Start with brackets first, inside the brackets, there are parenthesis, inside the parenthesis there is addition. 5+3 is 8. carrying on, inside the brackets, we have 2^3, which is an exponent. 2x2x2 is 8. Now we see we have the problem 3+8-8 is inside our brackets. The 8s cancel each other out, one acting positive and one acting negative, so we are left with 3. Now our equation is 3+8[3] 8x3 is 24. 24+3 is 27. Simple.
>>
>>700625003
College. You cannot do higher math if you don't know what the distributive property is.

Look it up.

If you see 2(1+2) it is the exact same as (2*1 + 2*2).

It is a standard rule in math.

>>
>>700625737
The distributive property does not apply in this case. I guarantee if this was on a math test, the way that gets 9 would be marked correct. Distributive only works if the number outside is not being affected, however for it to do Like that in this equation, it would have to start out the equation. If the equation did not have the six there, starting with distributing the two would work.
>>
>>700626373
It does apply because the division symbol like that is ambiguous and we do not know what the full denominator is.
>>
>>700612929
6/2 = 3
3×(2+1)
3×3=9

It's not ambiguous. Even if you saw this wrote as a fraction, you would do what is inside the parenthesis first. You've overcomplicating a first grade level problem

6/2(1+2)
=6/2*(1+2)
=6*(1/2)*(1+2)
=6*(0.5)*(3)

For it to be 1, it would have to have been written as:
6/(2(1+2))=?
In which case:
6/(2(1+2))
=6/(2*(1+2))
=6/(2*3)
=6/6
=1
>>
>>700628020
No not always. One could say the opposite about having a space between the 2 and the (1+2).

The reason why this problem and problems like it cause so much controversy and are posted is because they are ambiguous and can be interpreted different ways.
>>
>>700612929

Some uneducated retards on here will come up with 9, but the answer is actually 1

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

I think the problem is that you're looking at this as a "mathematician" and I'm looking at it as a "programmer". In my defense, / = ÷, which in your case, isn't.

Unfortunatly this is what the obama administration wants to create. Bush made it where you couldn't fail a grade (no child left behind) so instead of trying to make sure children are learning the materials, they advance them so they will never get it.

Obama and Common Core now made it so not only can they not fail but they will never get right answer. But instead of calling them a dumbass we allow them to become engineers because as long as they have a good reason for how they got to their solution it ok. Like dumping coal ash into the water supply. It ok folks they had a good reason!

/6

was that so hard? I understand the confusion as multiplication and division are technically does at the same time, but one function carries the parenthesis and thus is done first... lending priority

you complete all math functions of a parenthesis first..

the answer is 1.... or 9 if you are an unwashed heathen who goes left to right with no regard for parenthesis.
