I just want to make sure that we are all being kind to one another, as unkindness is unnecessary. With that said, please make sure that you are not giving our direct answers, as such is against OpenStudy's Code of Conduct. On OpenStudy, we want to make sure that we are helping others to learn, by teaching them step by step, rather than cutting their opportunity to learn short. Please try to guide the asker so that they get the answer themself. It not only benefits them, but it also benefits you, because you got the opportunity to help them learn! Thanks for everything you do for OpenStudy!
