What are the correct notations of one to two thousand in Roman numerals?

Answer 1

The way in which we write out Roman numerals today differs in many respects as to how the Romans actually did themselves inasmuch that todays rules governing the Roman numeral system were intoduced during the Middle Ages.

Yet there is compelling evidence to show that the equivalent of 1 to 2000 when converted into Roman numerals by the ancient Romans were once written out as follows:-

Fractions were used to a limited extent and S meant 1/2 or 0.5

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

Thousands: M and MM

To select any numerals simply write them out in descending order as in the following examples:-

12 = XII as seen on some clocks

29 = XXVIIII as seen on the Coliseum in Rome with other numerals

1776 = MDCCLXXVI as seen on dollar bills

1904 = MDCCCCIIII as seen on Harvard Medical School's Library

1910 = MDCCCCX as seen on Admiralty Arch in London

2000 = MM which is MMXII minus XII

To restrict long drawn out numerals a subtractive element was included within the Roman numeral system so that MDCCCCLXXXXVIIII (1999) can be abridged to IMM (2000-1) in the same way that LXXXVIIIIS (89.5) can be abridged to SXC (100-10.5) which author David Eugene Smith noted in his book 'History of Mathematics' volume 2 first published in 1925 and ISBN 0486 204 308
