还有英文字母计数:
ABCDEFG。。。
天干地支:
甲乙丙丁。。。
子丑寅卯。。。
很多
罗马人发明的罗马数字数字:
I II III IV V VI Ⅶ ⅧⅨ Ⅹ Ⅺ Ⅻ
七个基本符号:
I--1, V--5, X--10, L--50, C--100, D--500, M--1000
相同的数字并列,表示相加,如:III--3, CC--200
左边数字大于右边数字,也表示相加,如:VI--6, XII--12, CLX--160
右边数字大于左边数字,表示相减,如:IV--4, CM--900
这几个方法结合起来,就能表示所有的数,如:
MCMXLV--1945, MCDXXXVIII--1488
注意相减时只能“减一个”,如9是IX, 但8不能表示成IIX, 而只能是VIII。30是XXX, 不是XXL。同样1800只能是MDCCC, 不能是MCCM
