Roman Numerals

In Roman numerals, 609 is written as DCIX. D represents 500, C represents 100, and IX represents 9.

The Roman numerals for the date 06-03-2006 are VI.III.MCMVI

The above numbers converted into Roman numerals are M, CM, XC, XII and IX respectively whereas notwithstanding today's enumeration of Roman numerals the Romans themselves would have probably calculated them in the following manner:-

M+CM = CMM (1000+900 = 1900)

CMM+XC = XMM (1900+90 = 1990)

XMM+XII = MMII (1990+12 = 2002)

MII+IX = MMXI (2002+9 = 2011)

Alternatively the Romans could have calculated these numerals on an abacus counting device giving the same result as follows:-

M+DCCCC = MDCCCC (1000+900 = 1900)

MDCCCC+LXXXX = MDCCCCLXXXX (1900+90 = 1990)

MDCCCCLXXXX+XII = MMII (1990+12 = 2002)

MMII+VIIII = MMXI (2002+9 = 2011)

CDLV represents the Roman numeral for the number 455.

In the same order as asked, "MCMLXXVII/I/I" The "/" is just to separate, and is not to deal with the roman numerals in any way.

CCVI is the Roman Numeral for 206.

C = 100

C = 100

V = 5

I = 1

Half of that would be 103, written in Roman Numeral form as CIII.

2112 in Roman numerals is written as MMCXII.

In today's modern notation it is LXXIX but there is evidence to suggest that the Romans themselves would have wrote out 79 as LXXVIIII.

The value of the Roman numeral XIV is 14.

It is: XII-V-XCIII

ii plus xii equals xiv in Roman numerals.

Yes, the way that the Romans have created their number system means that all they have to do is add an extra I on to any number and it will be larger therefore creating every number.

The Roman numeral for 10 is X, for 26 is XXVI, and for 2012 is MMXII.

The Roman numeral that comes after MXCIV is MXCV (1095).

IX represents the number 9 in Roman numerals. Roman numerals are derived from the ancient Roman numbering system and are still used today in various contexts, such as on clocks, book chapters, and movie production dates.

XXI is the Roman Numeral for 21 and would be used on a clock using the 24 hour, or military, time system where 000 (or zero hundred) hours is midnight, 1200 (twelve hundred) hours is 12:00 noon, and 2400 (twenty four hundred) hours is midnight again. This system avoids confusion as to which time of day is being referred to...which could be catastrophic in a military situation.

21 or XXI on the clock would refer to 2100 hours which is 9:00PM by conventional time.

The date 22 03 2012 in Roman numerals is XXII III MMXII.

In todays usage of Roman numerals: IV-VII-MCMXCIII

dcccxviii (in capital letters) 500+100+100+100+10+5+1+1+1

In today's terms of notating Roman numerals: XVI-VI-MCMXCVI

None. Roman numerals use the letters I, V, X, L, C, D and M (upper or lower case), not numeric digits (there is no 1 symbol in Roman numerals).

However, there are a total of 168 occurrences of the letter I in the numbers 1-120.

1-10: i, ii, iii, iv, v, vi, vii, viii, ix, x

11-20: xi, xii, xiii, xiv, xv, xvi, xvii, xviii, xix, xx

21-30: xxi, xxii, xxiii, xxiv, xxv, xxvi, xxvii, xxviii, xxix, xxx

31-40: xxxi, xxxii, xxxiii, xxxiv, xxxv, xxxvi, xxxvii, xxxviii, xxxix, xl

41-50: xli, xlii, xliii, xliv, xlv, xlvi, xlvii, xlviii, xlix, l

51-60: li, lii, liii, liv, lv, lvi, lvii, lviii, lix, lx

61-70: lxi, lxii, lxiii, lxiv, lxv, lxvi, lxvii, lxviii, lxix, lxx

71-80: lxxi, lxxii, lxxiii, lxxiv, lxxv, lxxvi, lxxvii, lxxviii, lxxix, lxxx

81-90: lxxxi, lxxxii, lxxxiii, lxxxiv, lxxxv, lxxxvi, lxxxvii, lxxxviii, lxxxix, xc

91-100: xci, xcii, xciii, xciv, xcv, xcvi, xcvii, xcviii, xcix, c

101-110: ci, cii, ciii, civ, cv, cvi, cvii, cviii, cix, cx

111-120: cxi, cxii, cxiii, cxiv, cxv, cxvi, cxvii, cxviii, cxix, cxx

M=1000 X=10 V=5 I=1

Therefore: 1-19-2005 = I-XIX-MMV

An X with a line over the top of it represents 10,000.

V = 5000

X = 10000

L = 50000

Note that all three numerals above should be represented with lines above them to denote their difference from 5, 10, and 50 respectively.

However, Nowadays the use of the Horizontal Line running parallel verticlated of the symbol has been slowly phased out so 10000 would literally be MMMMMMMMMM and yes... 100000 would mean a lot of M's!! 9000 would not apply to any rule and would be MMMMMMMMM but as you can use the line if you still want to then 9000 would obviously be CMX with a line verticlated with the X

The number 7.
