Please clarify what can be done by people with low reputation points? I'm questioning about answers which don't answer the question, not questioning if the math is correct in these posts. Some of these posts are upvoted https://math.stackexchange.com/a/679047/85079.
I was apprised "declined - flags should not be used to indicate technical inaccuracies, or an altogether wrong answer."
I read http://meta.math.stackexchange.com/questions/4731/dont-flag-wrong-answers and http://meta.math.stackexchange.com/questions/4731/dont-flag-wrong-answers. The answer is to downvote? I'm loath to downvote because it can be loathsome to people.
The math is right, but because the two sentences comment on another way and not my questions 1-3, ergo it should be a comment.
