You don't have to give a thorough explanation. But something simple accompanied with the answer works fine. The assignment is due tonight I'd just like simple clarification. Most likely my teacher will go over the answers so you don't have to give a long explanation but I would like to know what I'm doing as I complete the assignment. Thank you!
