罗马数字Luómǎ shùzì古代罗马人记数用的符号。数字有I,V,X,L,C,D,M七个,依次表示下列数值:
1, 5, 10, 50, 100, 500, 1000。记数的方法如下{Roman numerals, including I, V, X, L, C, D, M, respectively meaning 1, 5, 10, 50, 100, 500, 1000. The counting rules are as follows}:
a)相同的数字并列,表示相加,如III=3, XX=20。{same numerals juxtaposed meaning addition, e.g. III=3, XX=20}b)不同的数字并列,右边的小于左边的,表示相加,如VIII是5＋3=8。{different numerals juxtaposed, with the right one smaller than the left one, meaning addition, e.g. VIII means 5＋3=8}c)不同的数字并列,左边的小于右边的,表示右边的减去左边的, 如IX是10-1=9。{different numerals juxtaposed, with the left one smaller than the right one, meaning subtraction, e.g. IX means 10-1=9}d)数字上加一条横线,表示一千倍,如是10×1,000=10,000。{adding a line above a numeral to express 1,000 times that number, e.g. is 10×1,000=10,000;}这几个方法结合起来,就可以表示所有的数,如XIV是10＋(5-1)=14。{The above methods combined can express all numbers, e.g. XIV means 10＋(5-1)=14.} |
