For a "show-work" question you will be asked to type your answer and supporting work in a math editor window. These questions will be manually graded. When you submit them, the score will register as a zero until I review them and assign a grade. Below are three samples of answers I have received in the past for a typical show-work question. Only one of them is acceptable; the other two received zero scores. Which one is the acceptable answer?

(A)
