Well, AJ wasn't so sure about the question. She was thinking of adding and subtracting, but that seemed like a very muggle answer and wasn't sure if she would seem dumb for saying it. Not that she was above giving out answers that may appear dumb. Sometimes those answers were considered out of the box and those got you points.

She heard Ethan giving an explanation and that sounded exactly like where her mind was going. Instead of saying the same exact thing, AJ jotted down notes. Notes that apparently came in handy for this class.
