I have a test on this tomorrow and I didn't get this lesson at all... After watching your video and writing down each step, it all clicked and made sense. Thank you very much~! :D If I may request, could you do two example problems at the end of each lesson and go through the steps? I think it would be helpful to some viewers. Thank you for taking the time to record and upload this video. :3

@Belldandy722 Good luck in your test. Point noted.
