Roman numbers from 1 to 1000?

Answer 1

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
