When I posted an answer from my another profile, it reached, in the first two seconds after posting, very bad score. Of course, it is always possible that someone simply dislike the answer, or the poster, or nickname, or anything. However, reaching score of -3 in the first few seconds after posting is something very concerning me.
This is the answer I'm talking about. I'm trying to see what is wrong in the answer, but I still have no idea. If there is some typo, someone usually leaves a comment without voting. However, very negative score may be reached only if the poster of the answer shows completely misunderstanding of the problem or provides completely useless information.
I would like to improve the answer, but without comment I really have no idea what people see so horrible in the answer. I tried to check if I maybe hhave made some miscalculations, but I think it is correct. Therefore, I'm not sure what to improve.
Why I've asking this here: simply because I don't see what is wrong with the answer and I would really like to improve it. If it turns out that nothing is wrong, but people just simply dislike that answer, I would leave it there, no matter how bad score is. But, I think it would be better to improve if something can be improved.
I would ask you to take a look at the answer and tell me what is wrong with it. Does it provide useless information or does it contain wrong math formula or wrong calculations?
Thank you in advance.
