What is six divided by two plus one times two?

1?

4?

5?

5?

Something else completely?

Well, whatever your answer is, you're completely correct (as long as you did the arithmetic correctly).

The problem with the phrase

What is six divided by two plus one times two?

is that it can be read in many different ways. For example, it could mean

6/2+1x2=5

or

(6/(2+1))x2=4

or

6/((2+1)x2)=1

or

6/(2+1x2)=3/2

or

6/(2+1x2)=3/2

The original statement is ambiguous and so providing a specific answer is difficult.

This sort of problem makes the rounds on the internet a lot, below is a Japanese version,

which shows that it is not just simply a problem with language. Mathematical operators can be written ambiguously as well.

Thus, if you arrive at such a question, the answer is not to angry, but try and understand how other people read the question.
