Contents of "Reasonable Linear Algebra"

For various reasons, the steam got out of my working on RDA. On the other hand, a lot of what is done in Arithmetic can easily be done with more than one kind of items. This is the so-called "fruit salad arithmetic" and, now that with the web, "baskets" have come of age and can be seen for what they are, namely vectors, I thought I would develop a bit what I once wrote in my Notes From the Mathematical Underground.
At this point, I will just upload what I am writing to Downloads rather than talk about it here.
