Let's say there is a question I asked to find out the error I made in my solution of a problem. Someone then answers, pointing out a "silly error" I made (like simple calculation error, or switching +,- signs).
So after finding out it was a "silly error", should the question be deleted?
The question will serve no purpose as a "useful reference" as it has no learning values, and will be a useless collection of data for the website. It will serve no use to the website or its users other than a "downvote target practice".
What should be the ethical or proper response?
