Everyone I have asked has gotten it wrong. Will you get it right, xkcd forums?

## Simple math problem

### Re: Simple math problem

Since you've posted an elementary problem and asked if we could "get it right" after incorrect answers from everyone else, I'm going to have to ask you to define all the symbols you've used.

What they (mathematicians) define as interesting depends on their particular field of study; mathematical anaylsts find pain and extreme confusion interesting, whereas geometers are interested in beauty.

Time to get a better calculator or learn how to use the one you have.

This is the latest "order of operations" thing that I've seen on facebook, following the a / b * c one. This isn't mathematics, it's troll maths - seeing people either get it wrong and be lambasted by the people who remember 2nd grade arithmetic, or get it right but then turn holier-than-thou in lambasting the people who don't. And this one isn't even slightly ambiguous, like the other one - unless you just plug it into an old calculator that can't handle proper order of operations, like letterX jokingly referred to, it's pretty easy to see that the x0 only applies to the last 1.

Could you rewrite the expression in postfix notation? I think that would help to clear any ambiguities in the problem.
