## How to write the Roman numerals/ Rules to write Roman numerals

There are some rules that we should follow to write numbers in Roman numerals. Some of the rules are given below-

- We can repeat any symbol maximum up to three times in a number. For example: We can use I for the number 1, and we can use it write the number 3 as III.
- The repetition of a symbols in a number gives the added value of its times of repetition. For example: to write the number 30, we can write XXX.
- We cannot repeat some symbols in Roman numerals. Those symbols are D, L, and V.
- We can subtract the symbol I from only V and X, and X from only L, M, and C.
- We can never repeat the numbers D, L, and V in Roman numerals.

To form a number 9, we write IX. In this number, X has a greater value, and I has a lesser value. It is subtracted when we put the symbol of a lesser value before the greater value symbol. IX = X – I = 9

To form a number 11, we write XI. It is added when we put the symbol of lesser value after the greater value symbol. XI = X + I = 11

### Conversion of Roman numerals to numbers

**Rule 1:** If a lesser value symbol is before the greater value symbol, subtract the value.

Here are some examples-

- IV = V (5) – I (1) = 4
- IX = X (10) – I (1) = 9
- XL = X (10) – L (50) = 40
- XC = X (10) – C (100) = 90

**Rule 2:** If a lesser value symbol is after the greater value symbol, add the value.

Here are some examples-

- VI = V (5) + I (1) = 6
- VII = V (5) + I (1) + I (1) = 7
- XI = X (10) + I (1) = 11
- XIII = X (10) + I (1) + I (1) + I (1) = 13
- LX = L (50) + X (10) = 60
- LXV = L (50) + X (10) + V (5) = 65
- CX = C (100) + X (10) = 110
