你那本《History of Mathematics》很棒，但我更喜欢 D.E. Smith 的两卷本。第一卷在这：http://www.amazon.com/History-Mathematics-Vol-Dover-Books/dp...
Your History of Mathematics is great, but I prefer the two volume work by D.E. Smith. Here's volume 1: http://www.amazon.com/History-Mathematics-Vol-Dover-Books/dp...
……从左到右。David Eugene Smith 在其《History of Mathematics》第一卷第 6 章和第 8 章中，详细记述了 1200 至 1600 年间十进制记数和算术随后传播到欧洲各地的过程。
…from left to right. A detailed account of the subsequent propagation of decimal numeration and arithmetic into all parts of Europe during the period 1200-1600 has been given by David Eugene Smith in his History of Mathematics I, chapters 6 and 8."
这种猜测至少可以追溯到 David Eugene Smith（1925）的《History of Mathematics》第二卷第 59 页：“有一种可能是，罗马人避免使用 IV，即 IVPITER 的首字母，就像希伯来人在写 15 时避免写 יה，巴比伦人避免用他们表示 19 的自然形式，……
This bit of speculation goes back at least to David Eugene Smith (1925), "History of Mathematics", volume II, page 59: "There is a possibility that the Romans avoided IV, the initials of IVPITER, just as the Hebrews avoided יה in writing 15, as the Babylonians avoided their natural form for 19,…
