You know it's a big giảm giá because the equation has its own meme definition on KnowYourMeme.

It says: "8÷2(2+2) = ? sometimes written as 8/2(2+2), is an ambiguous algebraic equation that was widely circulated online in late July 2019.

"On Twitter, the most common answers khổng lồ the problem were one & 16, causing lengthy debates between the users over how to identify the correct order of operations."

But what is the correct answer?

Half think 8 ÷ 2(2 + 2) = 1

A lot of people think the answer to lớn the question is one. Because you bởi the brackets first & get four, multiply that by the two outside the brackets & get eight và then eight divided by eight is one.

According to an anonymous Oxford University professor who spoke khổng lồ The Mirror: "Without better brackets, there can be ambiguity. There are conventions about the order of operations lớn try khổng lồ resolve this, sometimes called BODMAS in UK schools.

"If it still seems unclear, it's best khổng lồ include brackets lớn remove any possible ambiguity. Mathematicians vì not generally have problems communicating with each other about things lượt thích this, but for whatever reason people seem khổng lồ enjoy posing these kinds of problems on social media!"

The answer actually depends on how you learned maths.

If you use the PEMDAS method (a more US method), the order of the equation is Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
