### 6.3 How to read and write Roman numerals?

Roman numerals are written by iterating the symbols.

I = 1

II = 2

III = 3

IV = 4

V = 5

VI = 6

VII = 7

VIII = 8

IX = 9

X = 10

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

### 6.3 How to write Large numbers?

Let's try to create a large number in Roman numerals. Let's write 1947 in roman.

Start from the left:

1000 = M

900 = CM

40 = XL

7 = VII

Now put them together MCMXLVII

### 6.4 Subtracting rules:

IV means 1 from 5, while VI means 5+1. Therefore a digit could be both positive and negative depending on whether it is to the right or left of the higher digit.

4 = IV (5 - 1)

9 = IX (10-1)

19 = XIX (10+10-1)

40 = XL (50-10)

90 = XC (100-10)

Various rules can be used for subtraction with Roman Numerals.

(a) Only subtract powers of ten (I, X, or C, but not V or L).

(b) Only subtract one numeral from another.

(c) Do not subtract a numeral from another that is more than 10 times greater.
