The great thing about maths is that, not like different topics like English or historical past, there’s normally just one appropriate reply.
However this query continues to stump individuals on-line because it first went viral two years in the past as there’s not one, however two attainable appropriate solutions – and the way you reply will rely on the way you have been taught maths.
Relying on which technique you used to resolve the query your reply might be both one or 16 – and neither reply is wrong.
American Mathematical Society public consciousness officer Mike Breen stated your reply can be dependant on whether or not you learnt maths utilizing the PEMDAS or BODMAS technique.
He defined why your reply might be totally different when the complicated equation first went viral again in 2019.
“The best way it’s written, it’s ambiguous. In math [sic], a whole lot of occasions there are ambiguities. Mathematicians attempt to make guidelines as exact as attainable,” Dr Breen advised Widespread Mechanics, based on The Sun.
The PEMDAS technique sees equations solved within the order of parentheses, exponents, multiplication, division, addition and subtraction.
PEMDAS would see you’re employed out what was contained in the brackets first after which multiply earlier than dividing final, that means your reply can be one.
However the BODMAS technique means you’ll remedy the query this fashion as a substitute: brackets, orders, division, multiplication, addition, subtraction.
Following the BODMAS technique you’ll nonetheless work out the brackets first however would then divide earlier than multiplying, that means your reply can be 16.
The PEMDAS technique is extra generally used within the US, whereas Britain and Australia have a tendency to show the BODMAS concept.
So, how did you go?
