Of course I don't think the user would word the question that way. More like (A+B) to the second power. Perhaps the user did not know how to show exponents as ^2.

The conflict of interest comment is offensive to me though. I didn't decide on anything, I did not flag you and if I am wrong I always take a flag; in fact, I flag myself when I am wrong. I merely weighed in on why I chose the answer I did. You getting a flag does not benefit me in any way.

Debnjerry, I believe what you said is true but only if the question is stated correctly .

Hi deb, I apologize if you were offended. I used the word "might" on my previous comment as I am not sure if you were the first expert who answered that question (as I do not see the expert name in the answer but on the succeeding ones, your name reflected as the expert who answered them). This is also where the conflict of interest might come in because if you were the first person who answered the question and mine was accepted as correct, then the first answer will be deemed incorrect. But again, I didn't mean to offend you but I now know that you were offended. I also would like to agree that YES, moderators flag themeselves. I've seen a lot of you doing that in the archive.

@yeswey, I do not think you flagged me because of that clear typo error on my solution (2&3 are next to each other in the keyboard).

@Andrew, I am not sure if there were answers/questions of mine that were deleted if they did not add value or the conversations were incomplete but I'm certain that when this flag came in, 0.50 was deducted. I also noticed that even when flags were lifted, whatever were deducted are not credited back but I just do not mind it but just want to reduce unnecessary flags.

All, I will hands off on this issue and will let admin decide whether my answer has to be deleted for the typo error as what Andrew confirmed on his comment or the flag is valid.

jtj_hello, based on my experience here. Whenever my answer was flagged and then unflagged, the earnings were credited back to my account. This was also clarified by Weegy Admin on the blogs.

It just happens that most of the time the updates are delayed, so it's difficult to determine how much you earned or lost for that answer.

It could also be possible that some of your answers were deleted because they don't have value and that they added up to the flagged answer you received.
