Yesterday, on the post Sharps vs Flats - Formula to determine correct sharp and flat notes in a scale, there was a weird answer. It had some kind of algorithm; to be honest, I didn't fully understand what it was saying, but it seemed an answer nonetheless.
But later, it was deleted (not by the owner). Why was it deleted?
A wrong answer is still an answer. We have votes to determine which answers are good and which are not.
I have had flags declined with that very same reason:
declined - "Wrong" answers are still answers. Vote, don't flag, if you disagree with a post.
So, I cannot see why the post was deleted.
