Downloads of "Reasonable Decimal Arithmetic"


By the end of January 2012 I came to accept that the way I had been going was not going to work the way I want RDA to work and I completely redid the first four chapters---which took quite a bit of painful "reassessing". The results are available immediately below the following Notes.

June 25, 2012:
June 29, 2012:
The latest version is immediately below this line.
Here is the current state of RDAv3.0 (It is fully linked and clicking on any line in any table of content will get you there.):

And, for those who prefer one thing at a time, here are the individual chapters in their current state:

PART ONE: THE LANGUAGE OF ARITHMETIC

Chapter 1 - Symbolic Systems This has in fact been stable since late 2011 and this 2013-09-23 edition is only the result of the nitpicking I have being doing each time I had been warming up for something else.
Chapter 1 - Symbolic Systems This 2014-07-22 edition is the result of the nitpicking I just did as I tried to read it as a beginner---with good will---would.

Chapter 2 - The Basic Ideas Stable as of June 25, 2012.
Chapter 2 - The Basic Ideas This 2014-07-27 edition is just the result of some nitpicking with the intent of makeing the text a bit smoother to read.
Chapter 2 - The Basic Ideas This 2014-07-28 edition corrects what I consider to be a serious structural mistake as well as some bad terminology. Compare 2.3 Lists, 2.4 Representing Large Collections in the 2014-07-27 edition with 2.3 Bunch Lists, 2.4 Splitting Large Collections, 2.5 Representing Large Collections in this edition.
Chapter 2 - The Core Ideas This 2014-07-31 edition corrects a few more structural defects.
Chapter 2 - Symbolic Systems This 2014-08-15 edition corrects a few more structural defects.
Chapter 2 - Symbolic Systems This 2014-08-22 edition introduces zero, restructures list-phrases and edits "Amounts of Stuff". Hopefully it's done.

Chapter 3 - The Decimal System Stable as of June 25, 2012.
Chapter 3 - Decimal System 1-Representing Numbers This 2014-08-15 edition tries to regroup things in a "more logical way".

Chapter 4 - The International System Of Units Stable as of June 25, 2012.
Chapter 4 - Decimal System 2-Representing Amounts This 2014-08-15 edition is to bring things in line with the "more logical way".
