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

i do parenthesis, multiplication, then division so i believe it’s 1

1. The amount of people saying 16 need to retake math 😭

took 3 calc classes, differential equations and linear algebra, it’s 16 bro

i have 2 math degrees it’s 1

The answer actually 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 BOMDAS method, then the order is Brackets, Order, Multiplication, Division, 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.
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 !

As it turns out, the way the equation is written intentionally confusing. A post meant to intentionally stew chaos on the internet? How groundbreaking.
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.
