The debate started on Twitter after a science enthusiast KJ Cheetham posted a Maths equation 230-220x0.5 and declared "5" as its answer.
"A Maths meme that is actually funny rather than stupid. Solve carefully! You probably won't believe it but the answer is '5'," Cheetham tweeted.
Netizans were left scratching their heads but do you know the actual answer?
The puzzle is not so difficult to solve and the answer is, indeed, "120" and not "5".
"Even if we solve without using the brackets, from left to right, subtraction is performed last. The explanation is 'DMAS' rule division, multiplication, addition and then subtraction from left to right," Sunita Tulsani, an MSc and B.Ed in Mathematics and a teacher told .
Applying the basics of mathematics, several users took up the challenge and solved the equation using the "BODMAS" method that suggests the sequence of solving as brackets, of, division, multiplication, addition and subtraction and derived "120" as the answer.
On the other hand, some users solved the equation face front subtracted first and multiplied later to derive "5" as the answer.
Some users, however, termed the equation "ambiguous".
"Not at all ambiguous as multiplication always comes before subtraction," tweeted Thony Christie, British-born historian of early modern science and Mathematics.
Even though math experts claim the correct answer is "120", some users said they would not be convinced unless the original poster of the question accepts he was wrong and declares "120" as the answer.
"If the answer is '120', the author of the question must admit it," a user tweeted.
However, Cheetham claimed that he did not invent the question but had merely shared it.
