Attachment 99785
I just saw the above on FaceBook.. Using the order of operations, the answer I came to was 1. However, a number of commenters insist passionately that the answer is 9. Some of them offer some semblance of an explanation why but I must admit, I was lost. Some people said they used something called PEDMAS which I honestly never heard of before (I know it as BOMDAS) and some people talked about some distribution principle behind their conclusions.
I'd be the first to admit that math really isn't my strong suit. I know that sounds strange coming from a programmer.
My question is, who is right ?
