I think of adding and subtracting as a rotation in a sense. I've placed the rules of group theory beside. Copied from

Love it! I don’t miss cleaning the erasers though (Catholic school) I have a virtual chalkboard app, ChalkDraw, on my iPad. Whenever I open the app I can see my kids want to choke me. They know some sort of math is coming
