Not an equation, mathlet.

It evaluates to 16 though.

>>11211754
wrong

>>11211724
16 but ÷ is cancer so don't use it

Parentheses go first so we take them away, leaving us with 8 / 2 * 2 + 2
Next we start with multiplication (M before D, as always) which gets us 8 / 4 + 2
Which can be rewritten as 8 / 6
Plug that into any basic calculator you have on hand and the answer starts with 1.3333... but keeps going forever because it is irrational

>>11211757
Yeah. forgot that multiplication and division operations have the same precedence and I did not evaluate from left to right.

Division and multiplication are the same thing. The answer is 8/2(4) or 4(4). This is how most computer applications would answer it. I have also not seen that division sign since 4th grade with the exception of poorly constructed statements like this. And I’ve taken 300 level math.

That isn't the issue. The issue is that people are assuming the implied multiplication between 2(2+2) drags the entire thing under the division. There is no rule that says this is the case.

Answer is 4(4). No indication of multiplication. Must be a stupid Amerimutt format.

PLEASE EXCUSE MY DEAR AUNT SALLY XD

I wish we'd just stop teaching kids to use ÷ and recognize that multiplication doesn't really have precedence over division. That rule is only necessary because of an ambiguous operator.

>>11212018
>not 8 / [2(2+2)]
I thought if it was right next to the bracket you did it first.

>>11211724
The error is obvious that some people want to change the order of operations because one part appears to be in the denominator but is not.

I blame mathfags for requiring every piece of a denominator to be within the same parenthesis.

>>11211762
underrated

>>11211724

>>11211724
Americans please learn about operator precedence.

>>11212139
I make this mistake all the time though. I swear we were taught an incorrect method in school.
A number next to a parenthesis should just be treated as a multiplication of the values preceding the parenthesis and shouldn't have a higher hierarchy than preceding divisions and multiplication.
I constantly make the mistake of assuming that the number next to the parenthesis is just treated as a bracket in BIMDAS, etc. The only time I don't do this is when the brackets have an indice.
I think it's the confusion created by things such as irrational numbers which for some reason wires my brain incorrectly.

Assuming that once we get to only pure multiplaction and division (everything the parenthesis being solved) it'd simply be a manner of going left to right
so it should boil down to 8/2 = 4 then multiplied 4 = 16

we are taught in school the convention to perform operations left to right. we very rarely learn its name "left associativity", and it only applies after [PB][EIO]DMAS rules are completed.
consider the simpler question 10-8-2
Left Associativity (LA) gives (10-8)-2 = 2-2 =0
Right Associativity (RA) gives 10-(8-2) = 10-6 = 4
There is a third option
Null Associativity wont make assumptions about which equi-precident operator goes first and results in SYNTAX ERROR.
Null associativity requires the person writing the equation to be explicit in which operations go first. Null associativity is present by default in 'word problem' mathematics or where actual real life systems are being modeled. Null associativity is also referred to as Chad Associativity as it wastes little time in dismissing shitty facebook memes. Petition your lawmakers to have Chad Associativity taught in schools so our grandkids wont have to suffer these threads

Yet another order of operations thread! Holy fuck, why haven't we banned these already?

Sigh. Let's establish our order of operations.
Parentheses first. Followed by Exponents, followed by Multiplication and Division, followed by Addition and Subtraction. When two steps are simultaneous, i.e. Multiplication and Division, we go left to right. This is well established universal rules for order of operations.

>>11211912
Is correct. However, if your country uses a different order of operations in your education please explain how it's different. This is why

1. When a question is not clear because of differences international rules regarding education in order of operations, the use of parentheses is necessary to avoid confusion.
2. Order of operations should be universally agreed upon and taught.
3. All order of operations questions should be banned on /sci/ for being stupid. A thread died for this.

Thank you, anon, I've been doing math wrong my entire life, on my way to CoolMathGames HQ to save our youth from further miseducation

>>11220853
That's not how the original problem was written, is it?

why do people need weird acronyms to remember the order of operations? it's not like the periodic table where there are over a hundred elements, it's literally just 4 things: parenthesis, exponents, multiplication, and addition. parenthesis isn't even an operation, it's just a grouping method to supersede the standard ordering, and the actual operations are just decreasing in order of powers. (exponent is multiplication of multiplications, multiplication is addition of additions, addition is value of values)

This question has been up for awhile and the answer is 16. I am a mathematician and I asked my colleagues, who answered 1, 16, 16, 1. I was one of the colleagues who said it was 1 but I was wrong. The answer is as follows:

(8/2)*(2+2) = 4*4=16. This is the consensus an entire math department came to about this silly ass question.

We noted that this is why the traditional division symbol is no longer used. It is ambiguous.

It’s just written poorly. 8 ÷ 2(2+2) is purposefully fucked up. Ask 8/2(2+2) and only retards get it wrong

>>11211762
Was cracking up even before I got to "irrational"... Made my evening, anon. :)

I guess I forgot order of ops because I thought it was 1 at first. However, nobody writes fractions this way outside of elementary school and the businessfag containment zone. I'd do fine explaining why conformal mappings are useful or deriving Fokker-Planck, but I guess arithmetic is beyond me.

>t 164 IQlet

>>11222032
it is 1 with order of ops you multiply through the brackets first. only brainlets (americans) would do otherwise.

>>11211724
it’s 4, of course. the constant function 2 is applied to 2+2= 4, returning 2, and then 8 is divided by 2.
also, you always use explicit multiplication signs when only numbers figure in the expression.
also, the precedences and associativities of division and multiplication signs were never standardized. we were forbidden to use this division sign except for elementary number against number divisions. you draw a fraction line, exactly because the precedence and associativity is not defined in this case.
also, whoever thinks posting this shit is cool should kill himself with great cruelty.

alright you homos it is 1 stop trolling, computers autocorrect these parenthesis to (8/2)*(2+2) when that doesnt make sense for any real mathematician. You neets read all like a computer so try to remember some basic algebra from high school and answer:
>8/2x, of which x=2
/sci/ is full of retards now.

it's 16

>>11211762
>Parentheses go first so we take them away, leaving us with 8 / 2 * 2 + 2

>>11211904
Humanitiesfag here too. PEMDAS words kind of like case declensions in languages like Classical Latin, which there's no a priori reason for in either case, and is followed strictly due to convention.

fucking cunts should began to write down shit correctly, if a person show me a problem writen like that, the first thing i would do is puching him/her in the fucking face, math problems have a nomenclature, its like fucking orthography rules. fuck off.

>>11211762
>plug that into any basic calculator you have on hand
This is the funniest part for some reason

>>11211724
the answer could be both 1 or 16.... because the problem is written in an ambiguous fashion.

>>11228538
>>11229950
this...
the problem is ambiguous because you could do either multiplication first or division depending on the method you use: >>11228177

>>11212885
it is indeed irrational

>>11211724
The correct answer is to mark it wrong and tell your student to be less ambiguous.

Also, is there anyone who thinks 1/2π = π/2?

Based but incorrect. I've sen a similar thread like this on /b/ and the answer is yellow.

>>11211724
It's 1.333...

Left to right, brackets first so
2(2 is 4
4+2) is 6
8/6 simplifies to 4/3 which is 1+1/3

The answer is 16. There are no "buts" here.

Mathematics are ruled by standard conventions world-wide. You always solve your expressions from left to right.

>this thread
Jesus christ are americans really this fucking retarded?

>>11211724
it's not a maths problem, it's a notation problem.

8 / 2 (2 + 2) = x
8 = 2x (2 + 2)
8 = 4x + 4x
8 = 8x
x = 1

If I see another nigger post a fucking PEMDAS question with this faggy symbol...

>>11211754
Correct. Sucks People don't know what parentheses means. It's basically 8÷2x where x=4

>>11211792
You should treat parentheses as if it's a variable. 8 divided by 2x with x=4. Gives you 1.

unironically my math teacher in high school told the class that if everything has same precedence then it can be done in any order

division symbol doesn't exist in higher maths, it's for teaching brainlet kids fractions without actually teaching them fractions

>>11213996
I would argue you can skip the summation by saying 8 x 8^-1 is 1 because any element of a set combined with its inverse in a binary operation results in the identity of that operation. so here 1 is the identity for real number multiplication.
or just say 8/8=1

>>11211762
surely if you take away the parentheses you mean 8 / 2 - 2 + 2 = 8 / 2 = 4 Quod Erat Demonsinmyassdum [blacksquare]

I got held back for two years when I was a kid because because of this stupid shit. And people wonder why geniuses like Einstein drop out of elementary school.

just do away with the obelus and X for multiplication

complete the following

÷ is to / as - is to ______

x is to · as + is to ______

If the answer was 16 it would be written as (8÷2)(2+2)
The answers is 1

>>11237335
Multiplication and division arent higher priority so it goes left to right retard

>>11211724
ITT retards who don't know that multiplication and division are the same thing and this is why they're grouped in PEMDAS and BODMAS.

Thanks asshole, my side already hurt as it is.

Google says it's 16

PEMDAS. the real answer is this 8/2*4
doing it like this 8/(2*2+2*2) is only for variables because they are not real and that's the only way to go forward in algebra

Daily reminder there is no such thing as "standard math".
The math people refer to is in fact a de-facto standard. It has never been codified in ANY proper standards body. Period.

Maths - the not even remotely universal language.

Easy.
