Q1 - Seems okay.  Starting with a negative coefficient will hurt someone's feelings.
Q2 - Yup.
Q3 - Yes, again.
Q4 - Well, okay, but I would have preferred Addition or Subtraction.  This refers to what is actually going on rather than how it is written.

Okay, you did so well on that one you should have more confidence and go boldly through your next assignment.  It is time for you to verify your won answers!
