Hi Bob
I just wanted to thank you for posting the links in this thread. I have downloaded the scanned chapters and will look forward to exploring the videos.
Do you know any archives of elementary math? Apart from standard English texts, I have bought the complete sets of elementary math books from Singapore, China and Japan and would like to contrast these with the precold war US equivalents.
Thanks again!
Jonathan :)
