Message from User:Punkymonkeypun
Concering the omission of the first bead, i.e. chanege from the configuration from 2+5 to 1+5, i will tell you the source when I found the material again, it is in the in the book list I quoted, just you deleted all the list.

concerning they use pi = 3, it is in the other book, i will also tell you again once i find the isbn of that book.

also, the denotation of the number in romam abacus, they are deleted even i quote the isbn - but if you look at the photo (uploaded before, but not by me, the 'i' column is on the third column, start from right), so i suspect if any of you did read the passage. — The preceding unsigned comment was added by Punkymonkeypun (talk • contribs) 16:35, April 11, 2007 (UTC)


 * I can assure you that 400 years of Japanese abacus culture and learning was not the result of a misprint as you state in your revision, dated 15:08, 29 March 2007.

... once this convenient instrument of calculation became widely known in Japan, it [the abacus] was studied extensively and intensively by many mathematicians including Seki Kowa (1640-1708)... As a result of all this study the form and operational methods of the abacus have undergone one improvement after another. Like the present-day Chinese suan-pan, the soroban long had two beads above the beam and five below. But toward the close of the nineteenth century it was simplified by reducing the two beads above the beam to one and finally around 1920 if acquired its present shape by omitting yet another bead, reducing those below the beam from five to four. (Page 25)


 * Please don't miss the point. Wikipedia is not a place for you to air your perceived shortcomings of the Japanese school system. (Please refer back to my comments to you on the subject.)

 * As to your references on the Roman abacus? I'm sorry. I have no idea what you're getting at here. In any case, with the exception of a very minor edit this morning, I've never worked on the Roman abacus section.

A Question
How do I include an internal link in an "Edit Summary"?
 * Use square brackets, the same way as you would when editing a page (see Help:Link for more information). A simple link would just be written as Help:Link (for instance); if you want it to display text other than the target of the link, write it as help page about linking . (By the way, external links can't be included in edit summaries.) Hope that helps! --ais523 15:45, 16 April 2007 (UTC)
