First there are 7 distinct numerals from which to create all the other Roman numerals:

I =1

V =5

X =10

L =50

C =100

D =500

M =1000

To create other numerals you will need to combine two or more of the seven. So, for example, number 2 is II, 3 is III, but 4 is IV. Why? because IIII (four of the same number together) becomes unmanageable. Four then is created by placing I in front of V and subtracting 1 from 5 which equals 4.

So far then we have numerals for our Arabic numbers 1-5. We continue simply adding I to V: VI = 6, VII = 7, VIII=8, but 9 is IX. For the same reason we didn’t use IIII for 4, nine is created by placing I in front of X and subtracting 1 from 10 to get 9 (IX).

Are we beginning to see a pattern here?

Numerals above X (10) are XI, XII, XIII, XIV, XV, XVI, XVII, XVIII, XIX and XX is 20.

Then XXX = 30, XXXI = 31 and so on.

XL = 40, XLI = 41 etc.

LX = 60, LXX = 70, LXXX = 80, XC = 90

Let’s try to create a number in Roman numerals. How about 1944. Let’s start from the left:

1000 = M

900 = CM

40 = XL

4 = IV

Put together the numeral is MCMXLIV.

Most of the time Roman numerals are used to express year dates, especially the date for the making of a movie or a television program. Roman numerals are also used on formal documents and papers, analog clocks, and on building cornerstones.
