So, in contrast with the currently available standard textbooks, the texts to be found on A further discussion of these facts, and of how the texts on attempt to take them into consideration, can be found in Chapter Thirteen.

Two more facts govern the development of the texts on, namely that:

There are of course other possible approaches to mathematical exposition. For instance, Santos' amazing texts follow the Edmund Landau style of presentation.

Another one of the very few authors of texts off the beaten path and to be taken most seriously was Herb Gross but, very unfortunately, his texts and videos seem to have disappeared from the web. I should disclose the fact that Gross' treatment of Arithmetic and mine in Reasonable Decimal Arithmetic are very reminescent of each other and that, upon my discovery of his work, I wrote to him which resulted in a very pleasant exchange.

More generally, there are several sites in which free but fairly standard mathematical texts can be found such as Online Mathematics Textbooks,
