What are the ancient and modern notation of Roman numerals from 1 to 2000?

Answer 1

Ancient:-

Units: I, II, III, IIII, V, VI, VII, VIII and VIIII

Tens: X, XX, XXX, XXXX, L, LX, LXX, LXXX and LXXXX

Hundreds: C, CC, CCC, CCCC, D, DC, DCC, DCCC and DCCCC

1000 and 2000: M and MM

To choose any numerals simply write them out in descending as for example 1999 = MDCCCCLXXXXVIIII and by placing I to both sides of them they become IMM (2000-1) in the same way that VIIII changes to IX

Modern:-

Units: I, II, III, IV, V, VI, VII, VIII and IX

Tens: X, XX, XXX, XL, L, LX, LXX, LXXX and XC

Hundreds: C, CC, CCC, CD, D, DC, DCC, DCCC and CM

1000 and 2000: M and MM

To select any numerals simply write them out in descending order as for example 1999 = MCMXCIX which when added together properly as M+CM+XC+IX they too total IMM in the same way that V+IV = IX or VIIII

Todays version of Roman numerals were introduced during the Middle Ages presumably to make them more compatible with with Hindu-Arabic numerals that were fast becoming the dominant numeracy system in Western Europe at the time.

Remember: 5*I=V, 2*V=X, 5*X=L, 2*L=C, 5*C=D and 2*D=M
