I’m stuck on a Mathematics question and need an explanation.

Download the midterm document and type in your answers.
Write your answers out and upload your submission; you do not have to include the questions.
Type your answers directly into the submission box.
Save your exam as a Word (.doc) document, PDF, or JPEG image and submit as an attachment below when you are ready to submit the exam to be graded.

It is very important that you show your work for this exam. You will only receive partial credit if your work is not shown.
