…俄罗斯算盘 Tchoty [3] 并不划分算盘盘面，而是用两种颜色的珠子。如果你对“算盘/算筹板”的历史和种类这类大体全面的探讨感兴趣，K·梅宁格（K. Menninger）的《数词与数字符号》（Number Words and Number Symbols）[4]（我就是在里面读到了松崎清——人称“神之手”——击败托马斯·伊恩·伍德二等兵及其电子计算器的故事）是个不错的参考资源。五进制和十进制的变体讲得相当详细。那个…

If you are interested in the general topic of number systems let me recommend Menninger’s classic book Number Words and Number Symbols. Or you could try Chrisomalis’s other book Numerical Notation. Or Ifrah, The Universal History of Numbers. If you want to know about medieval European counting boards, look up Barnard (1916) The Casting-Counter…
