I thought I knew what an answer was but it turned out I'm mistaken.
1) Q: What is 2+2: A: 5 - that is an answer
2) Q: What is 2+2: A: I'd like to know what 3+3 is - that is not an answer
3) Q: What is 2+2: A: enter 2+2 into your calculator - that is an answer
4) Q: What is 2+2: A: The way to find that out is to ask someone who knows how to add up - that is an answer
Am I mistaken? For a notorious non-answerer I thought not-an-answer was correct for 4, but after receiving a rejection, it seems I'm wrong, and see that other people are doing this too.
What is the correct response for 4)? A downvote only?
