submit a single pdf document. You may either type or handwrite your answers or some combination if you like. You can take pictures of your handwritten responses, then include them in the single pdf document that you submit. Regardless of what you decide, it is important that your answers are as clear as possible. Your answers should appear in the order in which the questions are asked. Please review your answers before submitting them to confirm that they are easily readable. Be sure that you explicitly answer each question and explain each step, as if you were writing solutions so that another student in the class would be able to follow your thoughts. Part of your grade will depend on explaining each step of your answers.
