They're called brackets, American dog

That would be 8/8 you dumb twat

Parentheses first is the "(2+2) = 4" step. "4(4)" is a product.

Paratheses, multiplication, and then division.

2(2+2)

8÷8 = 1

The thing tripping you up is that the multiplication of the outside term with the parenthesis is just regular multiplication outside of parenthesis, and thus has no increased priority over the division before it.

>Parentheses first is the "(2+2) = 4" step. "4(4)" is a product.
Parenthesis first means that you first solve 2(2+2) which equals 8.

>and thus has no increased priority over the division before it.
It does, because it has no multiplication marker. Just the bracket. That means that it comes first.

You can rewrite 2(2+2) as 2 * (2+2)
They are 100% identical. It's not part of the parenthetical expression. You'll understand the order better when you do.

Its 1.

Please pass High School first before commenting, 16fags

>Multiplying a denominator

Usually in stuff I've done having multiple terms that involve multiplying something by stuff in parentheses they're separated by plus or minus and not division. Doing 2(4) first is second nature to me because of that but you do have to do the division first I'm pretty sure. It basically boils down to 8 / 2 * 4 = 4 * 4 = 16.

welcome to real maths

Did you not learn this in like 4th grade

if it's just multiplication and division you go left to right after brackets, so 8/2 is done first.

That's wrong. It's like stating that you can drop commas into sentences randomly.

No, it means you solve the (2 + 2). The outside 2 is just multiplication on equal priority with the 8.

HMMMMM

Because that's literally how you solve it, retard. You go from left to right after doing the parenthesis, fucking mong.

Division and multiplication are done left to right in that order. The division comes first and so is done first. (4) is identical to just 4. 2(4) is identical to 2 * 4.

The way the problem is written, 2(2+2) is not the denominator. 2 is the denominator and 8/2 is multiplied by (2+2).

Those are people that didn't pay attention. Multiplication and division are done left to right in whatever order they appear. One is not higher priority than the other.

The way to interpret it how YOU want would be to say 8 / (2(2 + 2)
The fact that the equation is NOT this should tell you something, but you're avoiding having to think about it.

the parenthesis go away if there's only one operation in it you idiot.

Which is why it would be written as 8/(2(2+2)) on the fucking chalkboard if you wanted it to go that way.

Assuming everything on the right side of a division symbol is apart of the denominator is going to get you fucked in math.

>Same volume
So it would stay the same.
Ping pong ball won't pull the scale up, and the weight of the steel ball doesn't matter as it's attached to a point outside the scale

The ping pong will float the scales up

Displacement is the same, but the left side also carries the weight of the string and ping pong ball, however little it is. Buoyancy does not come into play as long as the ball is not allowed to rise.
As such the left side is more heavy.

Here we go, this is the made-up rule that has tricked half the thread. This is not a rule. It's just regular multiplication, as if you had put a sign in.

The times 2 is not inside parentheses.

Solving (2+2) doesnt magically make the brackets vanish, you need to resolve 2 times (4)

The answer is 1

Well that computer's retarded.

I was always taught:
>x(y) = x*(y) = xy

So if you put in 8÷2*(2+2) you'd get the right answer.

IN PEMDAS, THE MULTIPLICATION AND DIVISION ARE DONE IN THE ORDER THEY APPEAR IN THE EQUATION FROM LEFT TO RIGHT

IF DIVISION APPEARS FIRST IN THE EQUATION, YOU DO IT BEFORE MULTIPLICATION

>Dumb fucks forget that multiplication and division are associative. It LITERALLY DOES NOT MATTER which order the operations are carried out in, so long as they all have the same priority.
Each individually is like this but if you're mixing them then doing one before the other will result in a different answer. (4*2)*2 is the same as 4*(2*2) but (4/2)*2 is not the same as 4/(2*2). For a math minor you can barely do middle school math.

it's also why no one writes divisions in a line anymore, even on modern calculators.

Because people doing serious math would never use 4/2*2 in the first place. It would be written as 4/2 * 2 or 4 / 2*2 or similar to avoid the sperging you retards are doing.

PEDMAS

>position A!
>position B!
>lol retards
>lol no u
The actual problem is nobody being capable of bridging the communication gap, which none of you can solve.

>It would be written as 4/2 * 2 or 4 / 2*2
You've got to be fucking kidding me

I have the degree to back it up. You got a gold star from your fourth grade teacher.

You have to convert to multiplication by the reciprocal for the associative property to hold true.

So 4/2/2 has to be written as 4 * 1/2 * 1/2 to be associative. And in actual use, such fraction strings are quite common.

PEMDAS is an incorrect algorithm, and if you were taught it, your instructors and/or insitution were wrong to do so.

If you do PEMDAS, the answer is 1. If you do BEDMAS, the answer is 16

lol go back to your remedial eighth grade math. Learn adult math.

Why you should ALWAYS write divisions as fractions: the thread

Hahahhahaha!!! American education... they only learn how to kill their fellows XD

how do you niggers get 16 or 1? I get 7

It's not completely incorrect, it's just simplified and incomplete. That's what happens when you dumb things down to teach to children rather than working at an adult level. For most people it will suffice, so long as the adults setting up their equations don't introduce things the children aren't equipped to handle.

it's funny because you missed the whole point of this and it's pathetic, i'm sure you were proud of yourself too.
since I coulds say:
(8/ (2(2+2))) /2= c/2
8/(2*2(2+2))=c/2
8/(4*4)=c/2
Dividing by 2 doesn't change shit to the equation

It's beacuse you are american... you guys have serious logical problems

See

They're identical and the only reason you would think they aren't is if you were taught wrong. In both cases multiplication and division should be done in whichever order they appear in the problem left to right. In this problem division is first and so division is done before multiplication.

-1

this

It's 1.

Why? Because in this equation, there are two terms. 8 and 2(2+2).

Why are there two terms? Because the (2+2) next to a number is not the same as a multiplication sign. It is the same operation, but a significantly different result, because before you can execute PEMDAS, you first have to simplify each term in the equation. You can simplify (2+2) into 4, and then you can simplify 2(4) into 8. then the equation reads 8/8 which equals 1.

Another way to think about it: in traditional algebra, the division sign is represented as a fraction with a top and bottom term. In this instance, the fraction would read

8
------
2(2+2)

in which case you'd simplify the top and bottom before simplifying the fraction itself, also giving you 1.

The only way you can reach the conclusion of 16 is if you treat the (2+2) as its own separate term, which would be incorrect.

Wait... so is Google wrong?

Such a long post for saying something so incorrect.

Any online tool (or calculator) you use is going to give you 16 because people in here are making up shit like "implied multiplication" to justify their ignorance.

8

>4/2/2 has to be written as 4 * 1/2 * 1/2
Congratulations, what you did here is prove that division is left-associative, and not actually associative as in the Associative Property

Frequently.

all throughout school, once you did what was in the parenthesis the parenthesis went away, so when its
8 / 2(2+2) it would then be 8/ 2*4 . then 8/8=1 . isnt the whole point to follow the order of what the words mean, so multiply is 1 step before dividing?? PEMDAS

that's pretty scary since many of these newly educated people will go into workforce where numbers are used. I'd be pissed if my accountant came up with 1 instead of 16

>Calculators are wrong, but I'm correct

So every calculator I own is also wrong???

His point is that 16 is the correct answer, and calculators are right and everybody here saying it's 1 is full of shit

>isnt the whole point to follow the order of what the words mean, so multiply is 1 step before dividing?? PEMDAS
No. Multiplication and division are on the same "level" just like addition and subtraction are. The order doesn't make any difference with addition and subtraction though so it doesn't matter with them, but the order of multiplication and division does matter and results in different answers. PEMDAS doesn't tell you to always do multiplication before division. You do whichever is first in left to right when reading the problem. In this case 8/2 is before 2*4 so you do division first. It's the same with BEDMAS. In the word it's DM but you do whichever is first left to right. There really needs to be another mnemonic that uses a word that encompasses both multiplication and division.

You're not going to find a single calculator or online tool that gives you 1 as an answer because they're programmed with the above in mind and don't mindlessly follow a mnemonic that they learned wrong.

Intentionally misguiding question because OP's equation isn't how it is to be written properly. Now solve it.

yo fuck common core why they teach us this bullshit in america i swear half the things kids know in school is wrong

Yeah, I'm just pointing out the stupidity of people claiming they're correct because of some stupid rule they made up

The way the problem is written it would actually be 8 over 2, all of that times (2+2). (2+2) isn't in the denominator. It would need to be written 8/(2(2+2)) to be interpreted like your image.

True

Europeans were getting it wrong above too and blaming it on Americans. It isn't strictly an American issue. I'm American, though I was probably taught before common core became a thing.

Kek

It's 1.

PEMDAS, the answer is 1 and everything else is wrong

Of you knew what pemdas was, you would know the answer isn’t 16

THIS

It's hard to tell if this is the teacher's fault or if you guys were just not paying attention in math class.

This is the hardest I've laughed in this board for a long fucking time.

I could direct the same question at you

For the record, answer is 16.

>GG Yea Forums
The sad state lf Yea Forums when the best thread you have came from Yea Forums, which is itself in a pretty sad state already

ITS FUCKING NOT

No man, PEMDAS is not a strict order. Multiplication and division are the same level of operation and are done from left to right. Had to learn that the embarrassing way during junior year of my Math degree. The way this is currently written you would have to do the 8/2 then * 4. You can google to verify. They are working to change it to a more comprehensive PE(MD)(AS) kind of system

>The mnemonic says to do multiplication before division so you have to do it!
t. Cletus repeating fifth grade for the 10th time

they taught us that it was a very strict order, so i would now blame the teachers.

>They are working to change it to a more comprehensive PE(MD)(AS) kind of system
This is how I was taught and it was drilled into my head. No idea what kinds of schools you guys are going to where they don't tell you that it isn't in the exact order of the mnemonic. How the hell do you make it 2 years into a math degree though without knowing the order of operations? Like I said above, are there words that encompass both multiplication and division? And also both addition and subtraction? If not there should be and it should be a 4 letter mnemonic.

You're the reason why implied multiplication was a fucking stupid concept that only serves to trip people up. Always write in your multiplication signs guys, it'll save you from trying to make dumb assumptions.

What nomenclature system are we using/what was the author's intent or the fundamental principles we're modeling?
>The only correct answer when doing math that actually means anything. Y'all can argue over which way it *should* be until kingdom come. I just need to know what they meant and I'm off to building shit.

Yes it is, thats why its called the order of operations

left to right comes after the order of operations

P stands of parantheses, as i get rid of those mofuggas first

Probably factors and terms maybe

parentheses and brackets are the same. PEMDAS and BEDMAS are the same

Well what you say is interesting because division and subtraction are just concepts we use to make it easier to grasp. Subtraction is just adding a negative and division is just multiplication of a fraction. We give them separate names in order to learn them, but in terms of pure mathematics they are the same thing. To be more concise, the model should just be PEMA

This is where you're wrong though. 2(2+2), whenever you see this in a math problem, you should always distribute the 2:

2(4) or 4 + 4 = 8

Then you can apply the regular MDAS from the left to right.

en.wikipedia.org/wiki/Order_of_operations#Mnemonics

khanacademy.org/math/pre-algebra/pre-algebra-arith-prop/pre-algebra-order-of-operations/v/introduction-to-order-of-operations
I'm gonna be honest, if you're getting 1 and you're not trolling, you need to restart from here.

That would work too but I think that would also be confusing to the same people that are confused here. Though so would making up new words or using uncommon terms I guess. PEMA sounds like a good idea.

In this case the distribution is multiplication, which is done after the division because it's after the division in the problem.

Multiplication is left-associative, which means if there were another multiplication at the start you would solve that first before distributing (or otherwise multiplicating the parenthesis)

No, “distributing” the 2 is called multiplication. Which must be done from left to right alongside division. Since the division comes first, and there are no parenthesis to indicate order of operation beyond algebraic logic then the 2 stays in place. I hope that helps

No. Multiplication and division are the same thing and you would do them at the same time, as pictured. The rules for parentheses only apply to the INNER part, not to factors outside of them.

/Thread

If any of you got their math in polish schools i the 80's you"ll know the correct answer without thinking about it. We've been beaten with rulers, notebooks (hard cover) laught at and beaten up some more. We know math. Its 1

>8*(1/2) / (1/(2+2))

If you really want to drive the point home. Multiplying by a whole number is the same as dividing by its reciprocal although no one ever goes in that direction...

ITT: brainlets who rely on PEDMAS and can’t comprehend that 2x4 and 2(4) are not the same thing. Plus a few smart Yea Forumsros who answered 1.

I am so glad that everything I had to deal with involving fractions always was in "underscore" format, so easy mistakes like this never happen.
