I voted 16 so it's definitely not that.

Following normal order of operations, it is clearly 1. I'm not completely sure how people get 16 unless they are reading the divide sign as a + sign.

1 is my answer as well. The article gets at how one might make a case for 16. Apparently, Google and WolframAlpha calculators will give you 16.

Seems to come down to how you handle "implicit multiplication."

OK, I see how they are getting there now. I had always been taught to act on implied multiplication first.

And now I get how you get 1. Interesting.

Whether implicit or explicit, it's still multiplication, so shouldn't it always come before division?
