8 ÷ 2 (2 + 2) – the example looks like this, and it is composed incorrectly.
On Twitter, a popular mathematical example was gained that frustrated social network users who received different answers. However, it turned out that the first and second are right, and the problem is the incorrect notation of the example.
In the subscriptions, subscribers were divided into two camps – some got 16, and the others – 1. The first immediately began to mock the second and advised them to improve their mathematics, while others answered the same. Even calculators showed different answers.
Anything other than 1 is absolutely wrong hth— Alex⚓ (@ClassyXhakalaca) 28 July 2019
Everything except 1 is absolutely wrong.

I’M FED UP WITH YOU
i do parenthesis, multiplication, then division so i believe it’s 1— em ♥︎ (@pjmdolI) 28 July 2019
First, I calculated in parentheses, then multiplied, then divided, so I got 1
it’s 16 omg the replies embarrassing…— mark day ✰ (@gcfssea) 28 July 2019
It turns out 16, oh, replai just ashamed to read …
1. The amount of people saying 16 need to retake math 😭— JKOurEuphoria (@JungKookQueen97) 28 July 2019
The answer is 1. Everyone who speaks 16 must retake math
It’s clearly 1— Pornhub ARIA (@Pornhub) 31 July 2019
Obviously, the answer is 1
it’s 16 and if you say otherwise start packing your clown shoes 🤡— karla (@svhobi) 29 July 2019
It turns out 16, if you say something else, then start unpacking your clown shoes
The answer is 100— mark (@emocowboy410) 30 July 2019
8/2 = 60
2+2 = 5
60 x 5 = 100
The answer is 100
some of y’all failed math and it shows— yeeteth (@jedetestelait) 30 July 2019
Some of you have failed math
ive never seen someone this confident over a wrong answer 😭— 🙂 (@thatsatanickid) 30 July 2019
I have never seen anyone as confident in the wrong answer.
I’ve never seen someone so confident in calling a right answer wrong.— Rishi Padhy (@RishiPadhy) 30 July 2019
Never seen anyone so sure that he calls the right answer wrong
Some even began to quote their academic degrees and the number of courses studied as evidence that their answer was the only correct one.
i have 2 math degrees it’s 1— laur♏️ (@lauram_williams) 30 July 2019
I have two degrees in mathematics, the answer is 1
took 3 calc classes, differential equations and linear algebra, it's 16 bro— jake chyllenhaal (@corynhendrix) 30 July 2019
I took 3 courses on computation, differential equations and linear algebra, it turns out 16, bro
The discrepancy in the answers was due to the fact that some users multiplied at first, while others, on the contrary, shared.
2(2+2) = 2*4 = 8— Laurel M. Davila (@laureldavilacpa) 31 July 2019
8/8 = 1
(2+2) = 4— em! (@jimnlvr) 28 July 2019
8/2 = 4
4(4) = 16
As a result, Twitter users decided that everyone got different answers depending on what order of calculations they learned in school. Those who first multiplied used the PEMDAS method with the following calculation order: first open the parentheses, and then multiply, divide, add, and subtract. Those who first divided and then multiplied, used BODMAS – in it multiplication and division have the same priority, and the calculations are performed from left to right.
If you do PEMDAS, the answer is 1. If you do BEDMAS, the answer is 16 https://t.co/RVH4DwiA0i— Waell (@waellomo) 30 July 2019
If you count by PEMDAS, then the answer is 1. If by BODMAS, then – 16
In PEMDAS multiplication and division take equal priority so you do whichever is first from left to right. Same for addition and subtraction. pic.twitter.com/1617gChUms— George W. Kush (@supermaddd) 29 July 2019
With PEMDAS, multiplication and division have the same priority, you need to calculate what comes first from left to right. The same goes for addition and subtraction.
since part of the world teaches PEMDAS and part teaches BODMAS algebra can be quite confusing at times pic.twitter.com/UaXSPMwvYJ— Mark Bott (@questionablmark) 30 July 2019
Since one part of the world uses PEMDAS and the other BODMAS, algebra can sometimes become confusing.
However, in fact, the problem lies in the notation – the authors of the example forgot to put brackets, so there were two correct answers.
Both 1 and 16 are correct answers because the notation of the equation is incorrect. Can everyone stfu now? https://t.co/N5SFpSyewH— ᴋᴏᴏᴋᴀᴅᴏᴏᴋs (@bstpeach) 30 July 2019
Both 1 and 16 are correct answers, because the equation notation is incorrect. Can you finally shut up now?
Вот именно, что это не вопрос приоритетов. Это вопрос нотации. Типа я пишу a/b(x + y) – это дробь a/b умножается на (x + y). Если я хочу всю правую часть в знаменатель, то a/(b(x + y)— Андрей Коняев (@a_konyaev) 1 August 2019
