Would somebody please tell me what's wrong with that answer? Why would anybody give it a negative heart, or whatever you call them here? It's easy to tell that the majority of questions here are posted by children, but math kids are nice, and that any of them would be mean comes as a surprise. I started volunteering here because I have a passion to help people. I don't get paid for doing this, and I don't even expect gratitude, but is it too much to expect civility?
