# Can You Solve It? Simple Math Equation Goes Viral Since People Can’t Agree On One Answer

When I graduated from university, I thought that was the last time I’d have to do any serious mathematics. Boy, was I wrong. Not only do I still have to help my sisters out with their elementary school maths homework (trust me, it’s surprisingly difficult), but every time I log into Facebook, there’s always some tantalizing equation thrown at me, asking me to solve it.

“Only 1 in 1,000,000 people can solve this simple equation” — we’ve all seen taunts like these, inviting us to dust off our noggins and get our hands dirty with deceptively basic calculations. Well, here’s the newest ‘simple’ equation to go viral on the internet: 8 ÷ 2(2+2) = ? Have you worked out the answer yet? Are you sure? Have you double-checked everything? Did you show your work? Good!

### This equation looks simple enough, right? Right?

Odds are that you got one of two answers: you either belong to the huge swathe of internet users who got 1 or you’re one of the people whose answer is 16. The internet is raging with amateur and professional mathematicians debating what the real answer is. There may have been some arguments over who’s right. And some shouting. Maybe even some shoving.

Some internet users used calculators to show everyone that the answer was 16. Others referred to their ‘maths degrees’ as an appeal of authority to demonstrate that the answer was 1. Others still took this equation business a bit more seriously than you would expect, and suggested that both answers were correct… depending on what rules you use to figure out the answer.

### People couldn’t agree whether the answer to the equation was 1 or 16

The reason why there’s a lack of consensus regarding this equation is a fairly simple one. Different people are using different rules about what order everything should be calculated in. Whether, after adding 2 and 2 together in the brackets, you should divide 8 by 2 first or multiply what’s in the brackets by 2, instead. This sounds like a basic disagreement, but people got very heated over this.

Robert Glenn Howard, a social psychologist at the University of Wisconsin–Madison, told Slate that such equations are the same as riddles and games, and people get heated over such things because Facebook and other forums are a place for discussion: “People are already primed to engage in pretty intense deliberations, and that can bleed over into the way they play games.”

“Humans have used riddles as a form of play since ancient times,” Howard explained. “And sometimes people can get competitive and wrapped up in it.”

Just in case you were wondering, the answer to the equation is 16. No, wait. Never mind. Yep. Definitely 16. Definitely.

No. Spaceships explode because America hasn't adopted the metric system. That may be a good thing since too many people can't solve a basic math problem.

The problem is that some people are taking BODMAS and PEMDAS etc too literally. Even though Bodmas has Division before Multiplication and PEMDAS does the opposite, multiplication and division are EQUAL and therefore go left to right. Ditto addition and subtraction. Using PEMDAS order of operations, therefore, it is Parentheses, then Exponents, then Multiplication and Division, then Addition and Subtraction. There's no controversy here. There's only right and wrong.

@Teri Donovan thank you for explaining why I was wrong. I understand what you mean and it makes sense. Now I’ve learned something new, and upon further analyzing my post, I see where I went wrong.

Thank you this is how I was taught and I am glad to find someone who knows the same.

Yes! Bingo, that's the answer. If followed pedmas ppl get 1, but that's wrong. The acronym should be read as P/E/DM/AS, which gives the correct answer of 16. Like you said, the D and M are equal, so then all divide and multiply goes in order from left to right and same for A and S. Parentheses come first with the same order of operation followed within the parentheses first and then followed again out of the parentheses. I wonder why the ppl saying both answers are right think that?

I find it odd that people now call it "PEDMAS". I learned it as PEMDAS and either way works since M and D carry equal weight, but you can no longer remember it with the sentence Please Excuse My Dear Aunt Sally if you put the D before the M.

I like how you explain that. P/E/DM/AS is a good visual representation that's easy to understand.

@Alfred: 10000 would not be a correct answer, because '8' and '2' don't mean anything in binary. For the rest you are right. Both answers are correct, because we do not know which convention is used. In this iteration it is most likely asked just because different conventions are possible.

That's your interpretation of PEDMAS/PEMDAS. Any convention is open to interpretation, though some people will attempt to have the hard and fast 'rule'. Regardless, nobody is 'wrong' with 1 or 16, or another answer as long as they did their calculations correctly. If the question said "What is 8 / 2(2+2) using PEMDAS", then they could be considered wrong, but they didn't. 10000 is also a correct answer, even though you're probably thinking it's not because you assumed I was answering in decimal instead of binary... and that's no different from the assumption that we should use a particular order of operations.

This has nothing to do with doing division or multiplication first, it's about interpretation of the brackets & juxtaposition, as explained by the wikipedia article in one of the last posts. Apparently mathematicians disagree on whether 1 / 2x = (1 / 2)x

Dude I learned this on fifth grade and I'm in sixth grade right now this is easy crap

Thank you! have been trying to explain that too lots of people but they take it literally.

I thought the difference was what you consider “solve brackets first” to mean. I was taught “stop as soon as the brackets are no longer needed” while others learned “stop when you’ve gone through everything directly related to the brackets.” That means you either go 8/2(2+2)=8/2*(4)=8/2*4=4*4=16 or 8/2(2+2)=8/2*(4)=8/8=1. I’m not sure if one is definitively wrong or right; it’s a linguistic problem over a mathematical one (what the world “solve” means).

I learned PEMDAS differently...

I learned that in pemdas if you have the multiplication and division whichever comes first in the equation is the one you do first

The problem is what you do with (2+2) after you get "(4)". Do you then drop the parans and make it "4" or is it still "(4)". Depending on which you do, you will get 16 or 1. If you leave the parans, then it takes precedence to do first. If you drop them, then it's left to right. A computer will drop the paran and treat it as multiplication, with an integer. At least in python, that equation isn't even valid as written. It would be 8/2*(2+2) = 16.

4 with or without the parens doesn't matter. Because there is nothing to be solved if all you have is (4). 4 and (4) and the exact same, just 4

@Demonic cow- my phone does that a lot too! Why does it happen?

Honest question: if it were written 8/x(2+2), what would your answer be?

@ The Cappy I’m so glad people are starting to understand

That's really not the problem. [8÷2(4)] is [8÷2*4]. That's just a matter of notation. What's happening is that the (÷) and (*) operators have the same precedence, so it's performed left to right (just like (+) and (-) have the same precedence). Parentheses force things to happen first inside. But what happens to the product afterward wasn't affected by the parenthesis. The parentheses had shot their wad once they obtained (4). Really, the only controversy here has been that some people believe (*) should have had a higher precedence than (÷). Frankly, my own number theory comes from my 2 degrees in computer science. Since that's how we codified math in computers, I figured everybody had agreed on the order of operations. Apparently not though. Note, though, that everyone agrees (+) and (-) have the same precedence, and that you perform left to right. I suspect that (÷) and (*) should too, and that people are simply getting upset because they got the problem wrong.

You are wrong John. Listen to Cappy. Just calculate like you read, from left to right as long as it is the same prority of operation.

This comment has been deleted.

Ever hear the term "Occam's razor." Simplest answer is the correct one. I can solve the equation in 3 simple steps. 1) always do the operation within brackets FIRST. So: 2+2=4. 2) 2x4=8 3) 8/8=1 Or, as we say in medicine...when you hear the galloping of hooves think "horses" not "zebras."

Sorry, my comments have double post syndrome, please don’t downvote.🙂

16

Yeah

i love lamps.

I got the answer as 1. My life remains unchanged, lol.

Me too. And proud of myself I am. Because, math. I remember whining, in my years of school-aged misery, "Why do I need this? I'll never use any of this math in real life!" I stand corrected.

16!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The equation is written incorrectly. Parenthesis are missing. According to the place where you put the missing parenthesis the result is different. (8/2)(2+2) = 16 8/(2[2+2]) = 1

No. You don't need a parenthesis for it to be written correctly. Actually (8/2)(2+2) gets the same result as 8/2(2+2), also the same as simply 8*2*4

I would say the expression is incomplete rather than incorrect. If you programmed the expression as is into a computer language you would get an error. But I would not say that you had a lack of logic.

The equation is written the way it is written. its not incorrect. Why are you adding parenthesis for no reason? You wrote two equations that don't even match the original one. i don't understand you r lack of logic or why people up-voted this

correct answer...8/ 4(2x2)=8/4x4=8/8=1

Er no. 8/2x4 is 16.

Actually the problem is 8/2(2x2)

You wrote the equation wrong. 4x4 equals 16.

It's a very simple equation. 2+2 =4. 2x4=8; 8/8=1

8/2=4, 2+2=4, 4(4)=16

This comment is hidden. Click here to view.

And you got it wrong. Why don't you calculate from left to right at equal operations?

Yew: Cuz that's not how you calculate?

I get 57.

If anything, this is an argument for the fraction bar. The division sign means there's ambiguity in whether multiplication or division comes first, so people give answers dependng on which convention they use (I learned "dot before line")... And people can't agree because there's no meaning to the equation. In "real" maths, equations are tied to concepts, even if that fact is generally lost in the school setting. There's an underlying logic and the equation merely serves to tie down the specifics. This is the equivalent of a grammar war for, e.g., the sentence "We invited two strippers, Hitler and Stalin." - except with nonsensical words ("Do duggided two libabas, Niriri sen Dalili")- you don't know what it's about, so there's no way to deduce the underlying, "true" meaning and thus the "correct" convention.

Here are the two options 1) 8 / 2 (2+2) ---- 8 / 2 (4) ---- 8/2 * 4 -------- 4 * 4 = 16 2) 8/ 2(2+2) ----- 8 / 2(4) 8 / 8 = 1. I was taught to do it the first way. Who or what knows the order of operations so well that they can resolve this issue?

Sorry my post was wrong, I tried to help. I guess I overestimated my math skill and told you something wrong. Take pizza as an apology? 🍕🍕🍕

You do brackets first which is 4 so 8/2=4 and 4x4= 16. The other one is wrong.

there can only be 1

The equation is written wrong that is why it is vague to some. It should be 8/(2(2+2)) With the correct parentheses you do the inner to outer and you are good with 1 If you want a different answer then put different order of calculation

The order is left to right at equal operations. Why you change it with additional brackets?

Additional bracket is unnecessary here- it's like making it a different mathematical problem... This one is written right.

The problem is improperly presented. Whether you use BODMAS or PEMDAS. multiplication and division are equal priority, so parentheses must be used to clarify the statement, either 8/(2(2+2)) or (8/2)(2+2).

The answer is one. 8/2(2+2): according to BODMAS (brackets, orders, division & multiplication, addition & subtraction) you would do (2+2) first which comes out to be 4 therefore 8/2(4). Since the 4 is still in brackets, the operation done to it must come first, so 2x4=8 which leaves us with 8/8, which, of course, is 1.

How you use brackets is just stupid.

your continued ad hom surrender is accepted................again

When a single number is in a bracket that just means to multiply it. so you would divide the 8 and 2 before multiplying by the 4

It's 1

Yes, it's 1

It’s 16, now go back to school.

awwwww.......the irony is lost on you

It’s 1.

All of you are wrong. It's equation equals A Purple Penguin. You're welcome.

8 divided by 2 ok 4-- 4 . the bracet 2plus 2-- ok . 4 so meaning 4 times 4- ok 16 . ore specifc . or . divded 4 dived 4 - equals 1

It does not matter if you use BODMAS or PEMDAS the multiplication has parenthesis which comes before both division and multiplication. Answer is definitely 1

This comment is hidden. Click here to view.

It’s 16 if you use order of operations right. 8/2(2+2) = 8/2 (4) = 4 (4) = 16. And if you read the equation out loud you’ll say: eight divided by two times two plus two.

42...

The answer is 1. There's no debating the fucking answer. This is basic math. The only people who don't think it's 1 are idiots.

This comment is hidden. Click here to view.

If you get the answer of one, you would need an extra set of parentheses. 8/(2(2+2)) If you get the answer of 16, the equation would stay the same. 8/2(2+2)

And the answer is: Who the Hell cares? No matter what the answer is (one), writing an equation on the internet randomly is quite boring. Also, you could plug in any random string so long as the result is whole.

Honestly, this whole thing could be resolved if it was either written as (8/2)(2+2), which would = 16, or 8/[2(2+2)], which would =1.

The answer is 1

How about putting it in terms that little kids could understand. You have 8 cookies and you have to give it to 2 groups of 4 kids (i.e. each group with 2 boys and 2 girls). i.e. 8 cookies 2 x (2 boys + 2 girls) = 8 kids each gets 1 cookie! 😁

Just no. you have 2+2 cookies, then you have 8 divided by 2 cookies, then you have 4 cookies Times 4 Cookies and that equals you are just dumb for talking about cookies and getting it wrong. Im not much better because im talking about cookies too.

As a devoted BODMAS user, I'm team Equation = 1.

Even with BODMAS it should be 16. Or you never understood it.

HINT: BODMAS or BOMDSA makes no difference.

Both can be right depending on the rules you use for solving this. It's not the notation that makes math fun it's what the scribbles represent. Hence, everyone claiming to be certain of the answer and have a math degree is per my definition a liar or spend a lot of time on studying a subject without my passion for it ;)

That's not how this works. That's not how any of this works.

Yep that’s what I was trying to say. Part of the reason math can be so complicated is because it’s just a concept or idea, there are no biological or strict rules. Math is fluid and I have a headache now.

This comment is hidden. Click here to view.

You never understood math.

If you make it a word problem it makes more sense. You have eight apples that you divide among two groups, each group being made up of two boys and two girls. How many apples does each person get? One. Not sixteen.

It's because the 'divided by' symbol isn't a real mathematical operant. It's what we use for kids so they don't have to write on multiple lines. It's not a real operant because it forces you to assume bracketing - that's why all these questions depend on its use.

This "puzzle" is ambiguous on purpose, it's a clickbait "puzzle", why publicize it?

They shoulda added at least a million more parentheses if they wanted the answer to be clear.

BEDMAS...but I was always told D & M doesn't matter...so that's where you end up with either 1 or 16....I can't math

This comment is hidden. Click here to view.

If the priority is the same, do it from left to right. 16.

Done people failed math...the answer is always gonna be 16..

8/2(2+2) =1 (8/2)(2+2) = 16

It's obviously 1.

Microsoft Excel: We found a typo in your formula and tried to correct it

It's 1

Addition/subtraction

16....that's because I was told to do the brackets first, then the other equation and then you multiply them because that's what you do when there's no...you know...equation icon thing. Sorry guys. It's early and quite frankly this is the dummy version.

Okay...BEDMAS...that's what I was taught.

Its 1. The rule of parenthesis applies to what is inside plyus next to it. If you want the answer to be 16 you need to add a 1. Iow it would be 8 ÷ 2 × 1 (2+2). The parenthesis is a suggestive multiplication. Not a divisional multiplication. If you replace the conventional divisional sign with /, the 2 doesnt get separated from the parenthesis. In other words it does a multiplication function but is not a multiplication symbol function. In other words, you multiply the 2 with everything that is in the parenthesis. So 8 ÷ ((2 ×2) +(2×2) = 8 ÷ ((4)+(4)) = 8 ÷ 8 = 1. Or 8/ 2 (2+2).

Based on what my math teacher taught me, you always start with (), so, 4. Then, whether multiplication or division, you do whatever is first. So, 4 again. Multiply both since there is no symbol between the number and the (. So my answer is 16.

All these constant 'trick' math questions just go to show that BODMAS/PEMDAS are sh*tty conventions. The whole point of having a convention is to get everyone on the same page, so that they understand the same thing. But a huge portion of the population either don't know the conventions, don't get them right, or as in this case... using different (but similar) conventions. Math is great because the calculations themselves are either right or wrong. But reading and interpreting the equation is completely different, and is often ambiguous.

So only 1 in a million can do basic 5th grade Order of Operations? It's 16. Simple as that. Further evidence that 80% of the World's population are idiots. And most of that 80% live in the U.S.

This is stupid. There is literally 2 answers. No one is correct or incorrect since this equation doesn't have hard rules the way it is written. That's exactly why people are up in arms about it. I love all the maths wizards out there, stating they have degrees and such, and still claiming their 1 answer is the correct one. Insanity. This is what the internet is for, these days. Beefs where beefs shouldn't be, everyone so set on being correct

There are conventions in Maths, the answer here is definitely 1, by the conventions of Maths. The only way to not get 1 is to be unaware of mathematical conventions.

Or if you understand them

The answer is 1. Anything depends on assuming brackets based on the inclusion of the 'division' symbol - which is not a true mathematical operant

If there can be made mistake during calculating so easily the answer is that there should be more parathenses in the equation.

Clearly, there is another method of teaching than what is described. In both, the P and B have to be COMPLETELY solved first. The number next to the bracket is a part of the bracket equation, that you have to solve first in both methods. Now, perhaps in some parts of the world, or in modern teaching, it isnt done this way. But if you were in my Engineering classes 25 years ago in Australia, and answered other than '1', then you would have been wrong. Are they now teaching 16? Probably not there, because some of those students went on to be professors. But clearly somewhere in the world 16 is being taught.

BODMAS? PEDMAS? I learned BEDMAS so now I'm all kinds of confused. I got 1. Even still, if you hitchhike you know the universal answer is 42.

Oh for shit's sake the answer is 16. The equation is not written wrong dumbasses because you didn't write the damn thing. Never heard of BODMAS until I read the comments. You are all making too much out of this, give up already.

The only way to get 16 is to be mathematically illiterate.

The answer is in your heart.

and you only have 1 heart

42 :D (it's actually 1)

it is 16 because the problem is 8/2 (2+2)=? and 8/2=4, 2+2=4 and 4(4) or 4x4= 16

Its 16 because the problem is 8/2 (2+2)= ? and 8/2=4, 2+2=4 and 4(4) or 4x4= 16, therefore it is 16

The author of the P. E. M/D. A/S. mnemonic device made an effort to remind you that what is MINE is DEAR -- not two different things... and your Aunt Sally is both i.e., your AUNT is SALLY.

It's 16. We learned this at the start of sixth grade. The order of operations is Parentheses, Exponents, Division and Multiplication(or vice versa), Addition and Subtraction(or vice versa). Have fun learning!

It depends on what you use ex: Bemdas: 1 Pemdas:2

don't mind me, I'm only here for Iruka-Sensei.

same

(8/2)(2+2) = 16 8/2(2+2) =1

If you too dumb enough not to know the answer is 1 then you need to go back to where you got your degree(s) and get your money back. 🤦🏽♂️

It’s 2!!!

The correct answer is 6. 8÷2(2+2) 8÷4+4 2+4 =6

The point to the whole brouhaha is that unless you define your meanings and conditions before you start, you're replicating the Tower of Babel. Math is not an objective science - it doesn't exist outside the human mind. It's a tool to provide invaluable assistance in handling the many physical problems which would otherwise be done by repeated cut and tries. I think it is truly the closest thing to a miracle that mankind ever conceived as possibly the ultimate abstraction.

All I'm sure of is the dress is blue and black. Except when it's not.

PEMDAS (parentheses, exponents, multiplacation/division, subtraction, left to right is what i was taught, so it would be 16.

I'm an engineer and I got 1, but excel got 16. I trust excel... :)

Wait... I got eight.😂

Just obvious 1

Well it's obviously 16 duh

It's simple. Parenthesis first. Inside and out! There's no multiplication dividing the 2 from the parenthesis. Its a suggestive multiplication. The answer is therefore 1.

It's 1. It shall be and can only be 1. For the simple reason of both how it's written and the basic rules. Notice its 8*space*/*space* [secondary equation = 2(2+2)] as its written. The 2(2+2) has to be done first its a separate equation and joined together, so it must equal 8. When you plug that in it now goes 8 / 8 which must equal 1. Bracketed equations must come first regardless, how any mathematician does it. There are three other ways the answer can only be one. And one is mentioned above where you place substitute for x and y. If you got 16 and you worked say, nasa or a nuclear plant. You would probably be fired immediately as a hazard.

Well I got 1. But Ican see why it can be 16, but from my perspective (bodmas method) its 1. Since people are confusing multiplication and brackets in this equation to be the same thing is entirely incorrect. You use brackets when for things to take priority in the equation, hence 2(2+2). That is a bracketed equation so that must be 8. Since the 8/ part is not apart of the equation (notice the spaces between for the original image on this posr, it has spaces) it should count separately to the brackets. Like in language you count the spaces as part of the equation. This makes substitutions much easier and cancellation more accurate. There is a good example up above.

Pretty sure it’s sixteen. Am I doing something wrong? I learned this stuff two years ago but I suck at math. 8 divided by 2 is 4, 2 plus 2 is four, and in school I was taught to always multiply the stuff in parenthesis by what wasn’t. How do you get one?

Yeah that’s my question too

I suck at maths, but you always multiply before you divide. The answer is definitely (probably) 1. 😉

is this again one of the examples when someone is bullying poor uneducated Americans?

What? no one mentioned Americans

I did.

We use BIDMAS so for me it's 16

The answer is = Purple because aliens don't wear hats. Whew! Now that it's all over ,we can all go back to our actual life problems....

naruto <3

Lol...Riddles. my earlier comment suggest the answer is 1. You had taken your mind aback to 0.

I think clearly that the Answer is 0. Otherwise I had go with 16. As explained, depending on the mathematical rule the examiner is adopting he won't let in these two answers same time in a question with objective answers. We open the bracket first since 8 stands alone. That leaves us with 8/4+4= 0

PEMDAS. Any other method is wrong. That is all. No controversy, nothing to see here. Move along. Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. In that order. Always.

The answer is 16 and the rule is very simple. If there are parenthesis, you do that first no matter what. If you are only left with multiplication and division, you always do left to right. Same goes for addition and subtraction - always left to right. If there is a mix of division, subtraction, multiplication or addition and no parenthesis, you follow PEMDAS.

IT is 16: 2(4) is not one term, think of it as 2 • 4. Now its (8/2) • 4.....

The same equation is used in both calc and algebra but solved in a different ways. So the answer you get in calc is wrong in algabra and, the answer you get in algabra is Wrong in calc. So both 1 and 16 are right. At least that's what I think.

And by the way, when did this start?

That equation is written correctly and the answer is 16 , all of you trying to justify 1 as the answer should take several seats and ponder how you have those "degrees"

8/2(2+2) First do the brackets. 2+2=4. Then do 8/2=4. Then multiply. It equals sixteen.

2xBracket=Bracket+Bracket. The 2 that is multiplied with the bracket is PART of the bracket. So you have 8/[(2+2)+(2+2)]=1

Why are you adding brackets? there is no need to. Just do the equation as is

This comment section is disastrous. Everyone is downvoting who they disagree with and upvoting who they agree with. Can we all agree that math sucks and this doesn't matter/ affect anyone?

I thought you were supposed to DIVIDE the numbers inside the brackets by the number outside of brackets beside it. I'e been doing it all my life and I'll be sixty-six in three weeks. Now I see why I constantly failed math. Because my eyes freeze simply staring at numbers. Unless I'm weighing my dope.

Just took maths for dummies, but i think it’s 1

Srsly, guys, a first-year algebra student could see there is an operator missing!

i need to go to math another 45 whole minutes again for a whole year

THIS IS WHY I HATE MATHS 😝

16...unless our math teacher taught us B.S. 8÷2=4(4)=16

Math ... Aside, Comments ... Hilarious!

If you want the answer to be 1, you need another set of parens. 8 / (2(2+2))

It's Berenstain Bears!

The limit does not exist!

pemdas

parentheses still have priority... so, if we have 4 in parentheses, and we have a number before it, we must add up that parenthesis and get rid of them, after that we can use the first number in that example... so the answer is 1

Here's the thing. If math is to be considered a "universal language", then rules have to be hard and fast... no ambiguity. No "interpretational" situations like this. No assumptions. Otherwise, everything based on mathematics is based on a house of cards. No wonder they haven't been able to develop a grand unified field theory.

This isn't something that is ambiguous in the field of mathematics. First, no one would write an equation that way, they'd use a line so there'd be no ambiguity as to what the denominator is. Second, if you group it like 2(2+2) it's taken to mean that the whole thing is the denominator while if you were to write it as 2*(2+2) then it'd be understood as only 2 being the denominator. The only people who are confused by this are those that never went beyond high school maths.

The equation is written in an ambiguous way. The missing multiplication sign before the bracket makes it look like a multiplication denoted by juxtaposition, but this way of multiplication should be used only where symbols (letters) are involved like "2a". Whoever wrote this equation should have used a multiplication sign to make the left-to-right rule obvious, leading to the result 16.

Idiots... the correct answer is 1 you have to solve the parentheses and then multiply 2 by 2 plus 2

At equal operations like multiply/divide you do it from left to right.

If you don’t know how BODMAS or PEMDAS works, I’ll show you. (B) Brackets (O) Or (DM) Division/Multiplication; they are equal, therefore go from LEFT to RIGHT in the equation. (AS) Addition/Subtraction; they are equal, therefore go from LEFT to RIGHT in the equation. Same with PEMDAS. (P) Parentheses (E) Exponents (MD) Multiplication/Division; they are equal, therefore go from LEFT to RIGHT in the equation. (AS) Addition/Subtraction; they are equal, therefore go from LEFT to RIGHT in the equation. Maybe you should go back to school and learn this, so you don’t have to be taught be a fifth grader.

noted the author did not give what is the correct answer in the story.

He does not have too. It's maths, there is only one correct answer.

I think that was the point- so people are supposed to do it themselves?

Math is not a language?

May I can't do it in english, but in my native language I can say it in ways to support both results. By translating you start making things even harder. Just stay with maths. That's my point.

It is math, don't involve languages.

It's math! Not magic.

Wait... (I had some troubles with the battery). Try this way: "Eight divided by two and multiplied by the result of 2 plus 2". I think it goes like that...

Both the answers are correct.

It's 16 cuz 2+2 is 4. 8÷2 is 4. 4x4 is 16 that's ur answer and I'm only in the sixth grade

i did it and its 16

Lets make it simple. Add variables. 8 ÷ 2 (a + b) = 8 ÷ (2a + 2b) The 2 belongs to the parenthesis and the rule is parentheses first. Or rewrite the equation as 8 over 2 (2+2) = 1. Ill go further. 8 ÷ 2 ×(2+2) is wrong because you cannot put two symbols next to each other. That changes the equation. If you want the answer to be 16, the equation must be 8 ÷ 2 × 1 (2+2). The invisible one appears. And thats not the equation given. Thats the equation you altered. The answer is 1. Sorry.

You rare are all inventing whatever convenient system seems right to you, So I say, 8 divided by 2 =4. No argument there. And then 2 + 2 is clearly another 4 giving the unarguably answer is 44. End of conversation.

8/2(2+2)= 8/2(4)= 4(4)= 16

(2+2)=4 8/2=4 4x4=16 The answer is 16 if you follow PEDMAS

Please Excuse My Dear Aunt Susie. That rule has been around since forever. The answer is 1.

I hate mathematics with all my heart. But the answer is 8! Means long life and prosperity

It's 44.... problem solved and broke the tie.

We used BEDMAS Brackets,Exponents, Division,Multiplication, Adding and Subtracting. Everyone was taught differently and learn this in Jr high 32 years ago.

I wish i have a pink calculator.

Answer is 1

I don't know how the internet completely blows up when they see something so simple like math equations like these.

Four?

The correct answer is actually yellow

It just proves mathematics is hard. And you MUST define your methods first if you want to have a conversation using maths as the language.

These things are already defined, it's just that most people aren't aware of the definitions.

And yes another day I am glad I never need to use math formulas.

In the way that the equation was originally written, there are two separate equations that need to be reconciled amongst themselves. Do the separate equations and then reconcile them together. PEMDAS is real and the answer is 16. The answer where you get 1 is if you change how the equation is written. Jesus people...

This is why I could never help any of my five kids (over 17 years of changing methodologies). I'd go with one, based on my '60-'70s education.

It's 4. And I didn't even get GCSE maths.

It's 1. Funny thing is that considering that multiplication is associative and you switch 2x(2+2) to (2+2)x2...indeed, even Windows calculator gives you 4. But it's 1 in the end, because 2(2+2) is like (2x2+2x2).

If you do 2x(2+2) or (2+2)2x it leads to the same thing. (2+2) = 4 x 2x = 8x, and (2+2) = 4 x 2x = 8x. Maybe you should go back to 5th Grade. I’m a fifth grader.

Maybe you should cos it def isn't 4 ;)

How did you get 4? I understand how you can get to 1 by making a mistake, but 4 is new to me.

Its 16

how is no one getting 8? are people retarded? 8÷2 is 4. 2+2 is 4. together that makes 8. it's not hard.

Parentheses first, then multiplication and division at the same time, left to right: 8÷2(2+2)=8÷2x4=4x4=16 The only way to get the answer 1 is if all the 2s are bracketed in the denominator. 8÷[2(2+2)]=8÷[2x4]=8÷8=1

No, i saw blue!

2x(2+2) = (2+2)+(2+2). Here are your brackets. Answer is 1 in both BODMAS, PEMDAS and DUMBAS.

Balderdash Its all about a typo If you read the first sign as an add sign its 16. If you read it as a division sign its 1This i s about poor messaging not math.
