Math...


So I saw this picture on 9 gag today and the comments that follow it go on forever...

https://9gag.com/gag/4840184


The math problem is 48/2*(9+3)=  which can equal either 2 or 288 depending on how you solve it.


48/2*(9+3)
48/2*(12)
48/24
2


or


48/2*(9+3)
48/2*(12)
24*12
288

However the problem with this question in my opinion is the lack of sufficient parenthesis.

No good programmer, engineer, or math teacher would give or write a problem like that...

It should have been written;

48/(2*(9+3))

or

(48/2)*(9+3)

which would have solved any questions... then the order of operations isnt even a difficult question.   these questions are designed to get people riled up over a poorley written math problem.
