Summary: The author continues to explain the journey into algebra. It has long been acknowledged that `understanding and using notation' is key to success in learning algebra. The experiences documented here illustrate how this understanding can become a reality for most learners. Not through some particular alchemy that is beyond replication, but simply by using a wellresearched, and crafted software package. This learning media engages, challenges, and provides students with feedback that undoubtedly influences their learning. As you read, remember that the classroom and students described is `typical', exhibiting all the residual features than have the potential to influence the learning, in both a positive or negative sense. So, what makes the difference here? For Part I see [the author, ibid. 232, 2124 (2013; ME 2015f.01036)].
