8 ÷ 2(2+2). Simple, right? WRONG.
As someone who hasn't calculated anything more difficult than a restaurant tip in years, may I say that I can't believe we've made math trend on Twitter. You're all really gonna make me pull out my dusty TI-48 graphing calculator, huh. I'm really gonna have to dig through my post-grad brain like SpongeBob's memory files, burnt to a crisp, and calculate this equation.
OK, I guess we're doing this. Pop quiz folks — can you solve this controversial post?
Pencils down. What answer did you get? 1 or 16? The real answer may surprise you: no one can decide conclusively. Pretty anticlimactic, huh? Here I was thinking that some dashing math majors would sweep in and put an end to the madness, but even they can't stop this viral fight now.
Anything other than 1 is absolutely wrong hth

Brackets come first mate
— Toni 🇦🇹 (@GorgeousGio) July 28, 2019
i do parenthesis, multiplication, then division so i believe it’s 1

1. The amount of people saying 16 need to retake math 😭
— JKOurEuphoria (@JungKookQueen97) July 28, 2019
took 3 calc classes, differential equations and linear algebra, it's 16 bro

i have 2 math degrees it’s 1

The answer lies in the way you go about solving it, and that depends on where in the world you learned math. If you use the PEMDAS method, the order of the equation is Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. But if you were raised on the BODMAS method, then the order is Brackets, Orders, Division, Multiplication, Addition, Subtraction.
So technically, both are the right answers! Boo, that's no fun. As a millennial with pre-new math education, my conclusive answer is 1. But who am I to talk, I'm just a writer — let's hear what the experts have to say.
But the distinction between answers lies more in which notation you use to solve the equation, ÷ or /, than the difference between PEMDAS and BODMAS. It's intentionally confusing, and will yield you either 1 or 16 respectively, depending on how you input it and what order you solve the equation.
since part of the world teaches PEMDAS and part teaches BODMAS algebra can be quite confusing at times pic.twitter.com/UaXSPMwvYJ

You need to see the how bracket is created.
There can be two cases:
8 ÷ 2 x (2+2) = 8 ÷ 2 x 4 = 4 x 4 = 16
Case 2 (Given case):
8 ÷ 2(2+2) = 8 ÷ 2(4) = 8 ÷ 8 = 1
RULE is STEP-BY-STEP following of BODMAS (Bracket, Of, Divide, Multiply, Add, Subtract)
Hope it helps !

If you do PEMDAS, the answer is 1. If you do BEDMAS, the answer is 16 https://t.co/RVH4DwiA0i

okay we’re gonna re learn pemdas
m/d= multiplaction/division in order from LEFT to RIGHT
a/s = addition/subtraction in order from LEFT to RIGHT
thank u https://t.co/LO0TPxsL45

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

8÷2(2x2) = 8÷2(4) = 8÷8 = 1
= Answer is 1.
Solved Via "BODMAS" Rule :
O( f )
M x ultiplication

As it turns out, the way the equation is written intentionally confusing. A post meant to intentionally stew chaos on the internet? How groundbreaking.
Both 1 and 16 are correct answers because the notation of the equation is incorrect. Can everyone stfu now? https://t.co/N5SFpSyewH

This is why most teachers tell students to stop using ÷ pretty early on in learning.

There you have it folks! Math. We sure did solve it.
