• You are new here. Things will get better over time. People downvote for many reasons, not always predictable, and not always mathematical, not always fair. – Will Jagy Apr 23 '16 at 17:45
• Given the fact that your answer is completely wrong from a technical point of view (and I don't think that this is in dispute), I would say yes, delete it. If it was just a minor technical error but the rest of the answer is salvageable, then edit; in this case, I don't feel that applies. – user296602 Apr 23 '16 at 17:52
