Math question divides Internet because no one can agree on the correct answer | United Kingdom | New UK News

The tweet racked up nearly 20,000 retweets – and thousands of likes, too.

Another said: “You don’t need acronyms to evaluate 8 2 (2 + 2), the result is the same whether you do the + first or the ÷ first.

“Just follow these conventions: 1. Make the parenthesis, 2. Go left to right. The correct result is then 4 X 4 = 16. No memorization of acronyms.”

And another wrote: “The correct answer is 16. When the problem is at 8/2 (4), you have to calculate from left to right because multiplication and division have the same priority. So 8/2 first then 4 (4) = 16. Just remember the left-to-right rule, which is a rule that many people forget. “

Feeling confused? We asked the senior education consultant of the virtual tutoring company Maths-Whizz why this seemingly simple sum divides social media.

Turns out it’s a question of where you came from rather than whether or not you can get there or not, says Fiona Goddard.

While the BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) method is commonly taught here in UK, America, many use the PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) method.

She said: “It is up to all of us to agree to play by the same rules governing” the order of operations, because in this calculation we are faced with several mathematical operations to perform – evaluate expressions in parentheses, perform multiplying or dividing, or doing additions or subtractions – the order in which we do them can make a huge difference.
