The way we enumerate Roman numerals today is probably different in the way that the Romans actually did themselves so it's quite possible that they would have calculated their numerals on an abacus counting board in the following manner:-
Units from 1 to 9: I, II, III, IIII, V, VI, VII, VIII, VIIII
Tens from 10 to 90: X, XX, XXX, XXXX, L, LX, LXX, LXXX, LXXXX
Hundreds from 100 to 900: C, CC, CCC, CCCC, D, DC, DCC, DCCC, DCCCC
Thousand: M
To select a number simply write out the thousand followed by the hundreds followed by the tens and finally followed by the units:-
1999 = MDCCCCLXXXXVIIII which can be simplified to IMM
99 = LXXXXVIIII which can be simplified to IC
49 = XXXXVIIII which can be simplified to IL
9 = VIIII which can be simplified to IX
4 = IIII which can be simplified to IV
Evidence can be found today that the Romans probably formated their numerals in the above manner and sometimes simplified them as shown. For instance in the ruins of the Coliseum in Rome XXXX is simplified to XL
This question was asked and answered yesterday under: "1-1000 in roman numerals?"
It is: (M) which means 1000*1000 = 1,000,000
1 = i 10 = x 100 = c 1,000 = m
I 1 V 5 X 10 L 50 C 100 D 500 M 1000
1000
This question was asked and answered yesterday under: "1-1000 in roman numerals?"
It is: (M) which means 1000*1000 = 1,000,000
The numbers are written like this: 1=I, 10=X 100=C 1000=M.
1 = i 10 = x 100 = c 1,000 = m
I 1 V 5 X 10 L 50 C 100 D 500 M 1000
1000
On Converting between Arabic and Roman Numbers we get: M in roman numerals is written as 1000.
The Roman numeral is 'M'
M-MM
It is: (M)M which means 1000*1000*1000 = 1,000,000,000 In all reality the ancient Romans had little need for such large numbers
On Converting between Arabic and Roman Numbers we get: 1000 in roman numerals is written as : M
MDCCCXCI is in roman numerals. In normal numbers, it is:M = 1000, D = 500, C = 100, X = 10 and I = 1 so MDCCCXCI = 1000 + 500 + 100 + 100 + 100 + (100 - 10) + 1 = 1891.
