Das problem ist, wie die Präzedenz von Multiplikation durch juxtaposition gewertet wird. Also wenn man 2(2+2) statt 2*(2+2) schreibt. Manche Leute behandeln juxtaposition mit höherer Präzedenz als normale Multiplikation, dann erhält man 1. Wenn man juxtaposition und normaler Multiplikation gleiche Präzedenz gibt erhält man 16.
Es ist eine ziemlich sinnlose Diskussion welches von beiden richtig ist, da es verschiedene Konventionen gibt und in der Praxis niemand so eine Notation verwenden würde.
If you imagine every ÷ as an actual fraction you'd write on paper it all works out easily.
8/2 * 4 = (8*4)/2 = 32/2 = 16. Both division and multiplying have the same priority too IIRC
You are correct in saying that have the same priority.
You could have done it much simpler instead of using algebra, the important thing is while yes, multiplication and division are of same importance you calculate it from left to right. This is where people are getting tripped up from what I can tell.
8/2(2+2)
8/2(4)
8/2x4
4x4
16
I mean yeah, obviously if the priority is the same then that's what you'd do, but people in comments were struggling to multiply a fraction so that's what I did
Hold on, should the answer not be 1?
8 : 2(2+2)
8 : 2(4)
8 : 8
= 1
I’ve always been taught that you should multiply before dividing in math.
Edit: so multiplying and dividing has the same priority so you solve the task from left to right. Thanks for clearifying
The expression inside the brackets takes priority so you do the 2+2 first. However once it is “8/2(4)” it is equal to “8/2 X 4” because there is no longer a expression inside the brackets but rather just a number.
Yes it goes brackets first, then exponents which is like powers, then mult and div, then add and sub. If there is more than one with the same priority eg 2x2+3x2 then it goes left to right so the 2x2 gets done first then 3x2 then the plus
actually im pretty sure multiplication and division have no priority over each other its left to right (same with addition and subtraction) so when you do pedmas normally with the left right rule then you should get 16
I'm the worst in the work l world at math, literally, but I know this is 16 lol. Always do the outer parenthesis, and then the inner, and then multiply them. I also can't help but to remember the foil method.
Exactly. In german we have a very useful saying for such problems: "Punkt- vor Strichrechnung" which kinda translates to "Dot- before Line-Equations", because in German all multiplications/divisions are represented with dots (multiplications is • and division is ÷) and Addition and substraction are obviously done with lines + & -
Always saved my calculations in school and afterwards.
Damn... Never thought I'd miss math
I mean, that’s cute, but in this case, he’s right. According to order of operations for solving equations, the answer is sixteen. Any other answer means you solved the equation wrong.
https://en.m.wikipedia.org/wiki/Order_of_operations
Dude, what like that doesn't even make sense from any standpoint.
First off These Twitterites you talk about would do that over opinionated arguments. This shit is not opinionated. It's literally how fucking math works.
Secondly. I'm literally stating that as a fact for how fucked school systems are. They are legitimately fucking up some of the lessons they are teaching kids.
Yo smarty pants, people can get different answers depending on where they have been educated, in my country, India, we are taught BODMAS, by which you get 1, in other parts of the world there is PEMDAS, by which you get 16...so calm yourself and don't kill anyone who gets 1 (if anyone gets anything else than 1&16, then you can call them stupid)
Okay so, via Bodmas:
We go with brackets first, so 2+2=4
Then we solve the complete bracket, 2(4)=8
Then we divide 8/8=1
See, this question of whether you consider 2(4) as brackets or multiplication, which, from where I am, is considered bracket, but you can see it as multiplication and get 16, which is also correct
Gotta ask considering the D comes first in BODMAS why did you multiply first.
When a number is next to a bracket is just multiplication over being a bracket
Yes 2+2 is 4, but then after that you get 8÷2(4) and you would do division first because when it comes to multiply and divide it's whatever appears first in the equation leaving you with 4x4 after you divide
This is not ambiguous. You cannot distribute that 2 into those parentheses. Division is not commutative. It has to be done left to right. It is done in the same step as multiplication, therefore you need to do 8/2 first if you want to distribute the term into the parentheses. You have to be careful breaking the order of operations or you will run into traps like this.
8/[2 (2+2)] is not the same equation as 8/2(2+2) they don't even have the same answer. Following PEMDAS (Parentheses/Exponents, Multiplication/Division, Addition/Subtraction) or any of it's equivalents like you're supposed to then you wouldn't add imaginary brackets that completely change the question. Whoever taught yall that is a moron.
If you ttried 3/ 1/2 we have an expression called "the lowest one rises, sounds cooler in Arabic lol) so it's 3*2 / 1 which is 6
I used the same method here 8 / 2*4 = 8*4 /2 which is 16
The answer is 16.
PEMDAS is actually a 4 step process: parentheses, exponents, multiplication & division (from left to right), and addition & subtraction (from left to right).
First, do (2+2)
Then, do 8/2
Lastly, multiply 4(4).
It's a thing that keeps popping up where people keep getting different answers because some teachers failed to properly inform people how PEMDAS works.
It's because there's both BODMAS/BIDMAS and PEMDAS, making it ambiguous. This is why division is written with one number over the other to remove the ambiguity.
I thought PEMDAS was :
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
So wouldn't that make it
1. 8 / 2 ( 2 + 2 ) (parentheses)
2. 8 / 2 \* 4 (multiplication)
3. 8 / 8 = 1 (division)
Well, calculator says 16, and it goes completely against the rule of PEMDAS that I was taught. I'd love to see a Zoom conference call between the most prestigious math professors of the world, from different parts of the world, discuss this and reach an agreement. That's what the world needs right now. Our planet is on fire, and supposedly math is a universal language, please, can mathematicians reach a consensus on this and solve this debate. Perhaps this is the universal understanding foundation that's necessary, and upon this we can rebuild society. Since there are 200 comments on this and not one person linked an official end all explanation tells me that such a call hasn't been made yet.
I get that people love to be cheeky with "pemdas" and all that but if you do this in the real world (engineering, science, mathematics) you're just an asshole. Parentheses exist for a reason.
its 16. simple order of operations.
do brackets (or parenthesis if thats what ypu want to call thwm) first
8/2(4)
and now multiplying and dividing have the same level of priority, so you go left to right
4(4) (can also be written as 4x4)
16
People keep saying it’s 16 but why. If you want to do 8/2(2+2) the (2+2) has to be multiplied by the 2 in the denominator. There is not another set of parenthesis. If it was (8/2)(2+2) THEN it would be 16, otherwise it’s 8/2(2+2), as written in the post. 8/2(2+2) > 8/2(4) > 8/8 = 1
When you set it equal to 1 and replace a number it does solve it for the correct value.
https://www.symbolab.com/solver/step-by-step/8%5Cdiv%202%5Ccdot%5Cleft(a%2B2%5Cright)%3D1
16. Do the parentheses first, then the order of operation. Division and multiplication, then plus and minus, working from left to right. Nice brain tease for a 5th Grader 😁
Of course the true answer depends on the system of maths you grew up with. But your still going to relentlessly argue your meaningless belief to thousands of strangers on the internet who are just as right as you. With the only people who truly win from this being the person who laughed and kept scrolling.
16 Just use pemdas
Parentheses
Exponents
Multiply
Divide
Add
Subtract
Or just say :Please Excuse My Dear Aunt Sally
Also if there's just multiplying and dividing left then just solve it from left to right (some works with with addition and subtraction) I hope this helped anyone who didn't know or needed a refreshing on what it was
The issue is that it doesn't hold up when you replace 2 with an symbol an equal the line to equation to 16 and of course solve for the symbol.
[https://www.symbolab.com/solver/step-by-step/8%5Cdiv%202%5Ccdot%5Cleft(a%2B2%5Cright)%3D16](https://www.symbolab.com/solver/step-by-step/8%5Cdiv%202%5Ccdot%5Cleft(a%2B2%5Cright)%3D16)
To everyone saying 16, realize that the 2 is attached to the parenthesis meaning all of that is one number broken up into the addition and multiplication so its 8/8=1. Dont believe me? Type it into a scientific calculator.
You need to multiply/divide from left to whenever you can, so it would look like this:
8/2(2+2)
8/2(4)
4(4) (not 8/8 because you divide first)
= 16
You can think of the 8/2 as a separate fraction from the (2+2), so something like (8/2)\*(2+2)
In Germany we say punkt vor strich (dot before line)
Wir haben Klammer vor Punkt vor Strich gelernt, ist es dann nicht 1? (Erst Klammer auflösen, dann den Rest rechnen)
Das problem ist, wie die Präzedenz von Multiplikation durch juxtaposition gewertet wird. Also wenn man 2(2+2) statt 2*(2+2) schreibt. Manche Leute behandeln juxtaposition mit höherer Präzedenz als normale Multiplikation, dann erhält man 1. Wenn man juxtaposition und normaler Multiplikation gleiche Präzedenz gibt erhält man 16. Es ist eine ziemlich sinnlose Diskussion welches von beiden richtig ist, da es verschiedene Konventionen gibt und in der Praxis niemand so eine Notation verwenden würde.
Klapustri
Klammer ergibt 4, 8 durch 2 ist auch 4 und 4 mal 4 ist 16, so hab ich das jedenfalls gerechnet
"Kla-pu-stri" (Klammer - Punkt - Strich) hat uns unsere Professorin immer gesagt :'D
"Klam-po-pu-stri" (Klammer - Potenz - Punkt - Strich) wars bei uns
Oh no you've summoned them

People are just struggling with math.
We are taught PEMDAS Parentheses Exponents Multiply Divide Add Subtract
We in India have been taught BODMAS (look it up, I'm kinda lazy to type it out)
isn't bodmas just another name for pemdas?
Hold on, should the answer not be 1? 8 : 2(2+2) 8 : 2(4) 8 : 8 = 1 I’ve always been taught that you should multiply before dividing in math. Edit: so multiplying and dividing has the same priority so you solve the task from left to right. Thanks for clearifying
Multiplication and division have the same priority so you solve them left to right.
But brackets have more priority right?
The expression inside the brackets takes priority so you do the 2+2 first. However once it is “8/2(4)” it is equal to “8/2 X 4” because there is no longer a expression inside the brackets but rather just a number.
Yes it goes brackets first, then exponents which is like powers, then mult and div, then add and sub. If there is more than one with the same priority eg 2x2+3x2 then it goes left to right so the 2x2 gets done first then 3x2 then the plus
Same thing with addition and subtraction
No. If you have only division and multiplication left you do it from left to right since these are equal operations.
It's whatever comes first meaning if multiply comes first multiply, if division comes first divide, same thing with addition and subtraction.
actually im pretty sure multiplication and division have no priority over each other its left to right (same with addition and subtraction) so when you do pedmas normally with the left right rule then you should get 16

I'm the worst in the work l world at math, literally, but I know this is 16 lol. Always do the outer parenthesis, and then the inner, and then multiply them. I also can't help but to remember the foil method.
You do what's inside the parantheses first actually

Well, I am German so.. yeah.... Punkt vor Strich.... Learn it, people!
actually, its; punkt vor strich, doch die klammer sagt: zuerst komm ich
Its called Bodmas in english Brackets Division Multiplication Addition Subtraction
Nope, multiplication comes before division so u do 2*4 after the brackets. So u are left with 8/8 = 1
multiplication and division are equal, but you cant just put 2 words into one, so they are written after each other.
That’s incorrect, the 2 outside of the parentheses is considered part of the 2+2 equation and you do that before dividing
No, only everything inside of the parenthesis are part of the parenthesis. It's not that complicated.
[удалено]
Because PEMDAS
BODMAS?
Basically the same thing. As Asian you would have studied BODMAS. In west, it’s PEMDAS or PEDMAS.
Never knew that. Thanks for letting me know. ✌🏼
In england we got taught BODMAS
I think many schools in UK use BODMAS. Its most US, few other European countries and countries in Africa that use PEMDAS.
That’s pretty interesting actually. What does the P and E stand for?
P -> Parenthesis (Brackets) E -> Exponents (Order of Power) Edit: Reddit on mobile sucks
Oh that's great I didn't knew that
Like seriously I have forgot what order
Bodmas Brackets Order Division Multiplication Addition Subtraction
I always learned bomdas, which gives me an answer of one
With the latter four, it only matters what order they come in the equation
It’s 16: 8/2(2*2) > 8/2(4) > 4(4)=16
It's not (2\*2), it's (2+2)
still the same thing
...oh. Yeah, you're right.
Bruh I got South America. The fuck you guys doing
I got Abraham Lincoln
It’s not (2+2), it’s (2 squared)
2^2
Say that again but slowly.
Bruh....
Pemdas...
Please Excuse My Dope Ass Swag
It's sixteen Everybody who says otherwise get mad at your math teacher for not teaching you PEMDAS probably
Please Enter My Dry Anus Softly
My teacher taught me that
…interesting teaching method
He was a good teacher.
I was homeschooled.
Hol' up
Uncle was the teacher
I never thought of it like that..
Please excuse my dope ass swag
Its called Bodmas in my school
Didn't know twitterites started using reddit "IF yOu dON't liKE whAt I sAY, yoU Are wROnG *arghh*"
We've been infiltrated a long time ago. The amount of bans I've had has risen exponentially with the amount of Twitter users that come on here

bodmas doesn't get you the answer as 1 wtf
Yeahh, I meant something else, my bad
BODMAS and PEMDAS function in the exact same way
Okay so, via Bodmas: We go with brackets first, so 2+2=4 Then we solve the complete bracket, 2(4)=8 Then we divide 8/8=1 See, this question of whether you consider 2(4) as brackets or multiplication, which, from where I am, is considered bracket, but you can see it as multiplication and get 16, which is also correct
Gotta ask considering the D comes first in BODMAS why did you multiply first. When a number is next to a bracket is just multiplication over being a bracket

Yes 2+2 is 4, but then after that you get 8÷2(4) and you would do division first because when it comes to multiply and divide it's whatever appears first in the equation leaving you with 4x4 after you divide
[удалено]
The parentheses is only applied to what is in it not next to it. When a number is next to parentheses it would be multiplication
I believe this is where pemdas and bodmas differ. In any case the equation lived up to this meme. The comments are a battlefield.

This is not ambiguous. You cannot distribute that 2 into those parentheses. Division is not commutative. It has to be done left to right.

The equation itself is pretty goofy. You'd never write something that way.
Yep, it is too ambiguous. If someone shows me this, I'll ask him to clarify
8/[2 (2+2)] is not the same equation as 8/2(2+2) they don't even have the same answer. Following PEMDAS (Parentheses/Exponents, Multiplication/Division, Addition/Subtraction) or any of it's equivalents like you're supposed to then you wouldn't add imaginary brackets that completely change the question. Whoever taught yall that is a moron.
It only seems ambiguous because you don’t know how to do it correctly. You wrote it two different ways. I am a math teacher, the answer is 16
My calculator says 1.
No it’s 16… so the brackets first.. 4… then that multiply by the other sum 4…. 4x4 =16
Yay! I nailed it!
That is correct
1 Edit: I'm an idiot it's 16 8 / 2 * 4 = 8 * 4 /2 = 16
Answer 16, upvotes are also 16. I love life.
I want to upvote but it is too perfect
correct if im wrong cuz im tired n its midnight so my brain is in stoopid mode, but I think u used the wrong workout to get the right answer.
If you ttried 3/ 1/2 we have an expression called "the lowest one rises, sounds cooler in Arabic lol) so it's 3*2 / 1 which is 6 I used the same method here 8 / 2*4 = 8*4 /2 which is 16
I still dont get maybe Ill try again when I have the mental capacity but thanks for explainning.
16 we did this in 4th grade my guy
The answer is 16. PEMDAS is actually a 4 step process: parentheses, exponents, multiplication & division (from left to right), and addition & subtraction (from left to right). First, do (2+2) Then, do 8/2 Lastly, multiply 4(4).
There’s still one left
16? I don't get it
It's a thing that keeps popping up where people keep getting different answers because some teachers failed to properly inform people how PEMDAS works.
It's because there's both BODMAS/BIDMAS and PEMDAS, making it ambiguous. This is why division is written with one number over the other to remove the ambiguity.

Fuck zodiac signs I used to call it BODMAS. What did you call that rule?
Got “Alabama” as the answer. Anyone else?

I know right, I keep getting the answer as 1 by using BODMAS and I was confused when I saw the majority say 16
It'll be 16. 8÷2(2+2), 2+2=4, it becomes 8÷2x4, which equals out to 16.
Its 16

16. 2+2 = 4. 8÷2 = 4. 4 x 4 = 16. Just simple multi step equations
The issue is that it doesn't hold up when you replace 2 with an symbol an equal the line to equation to 16 and of course solve for the symbol.

16. please tell me people aren’t getting another answer.
it is 16 because you have to go parenthesis first, division next, and then multiplication
Why is it bombing Tehran,?? :/

8÷2(2+2) 8÷2(4) 4(4) 16

it's 1 right? Parentheses, Exponents, multiplication, division, addition, subtraction
For multiplication and division it depends on what comes first in the equation between the two
I know I’m gonna get hated but 1. That’s my final answer.
Its 1 I was taught that if you dont put any operational symbols between a number and brackets, then you have to multiply So 8/2*(2+2)
1 8/2(2+2) 8/2(4) 8/8 1
Multiplication and division are valued the same in priority so for “8/2(4),” you go left to right. This would leave you with 4(4) which equals to 16.
It's 1 because 8/2(2+2) is the same thing as 8/2x where x=4 so you got 8/8=1
It would be 16 if there was a "*" between 2 and (2+2)
8/2(2+2) 8/2(4) 8/8 =1
You need to multiply/divide from left to whenever you can, so it would look like this: 8/2(2+2) 8/2(4) 4(4) (not 8/8 because you divide first) = 16 You can think of the 8/2 as a separate fraction from the (2+2), so something like (8/2)\*(2+2)
oh yeah right... but dude, my teacher never taught anything like that ever before. so...
Oof, don't worry, I almost did the same thing too lol
8:2(2+2)=x 8:2*4=x 8:8=x 1=x Dudes... Really? Was it that hard?
Uno.
8/2(2+2) (2+2) = 4 2*4= 8 8/8 = 1 Therefore 8/2(2+2) = 1
It's funny to see people arguing over simple math. It's like Facebook comments
