Understanding Roman Numerals Basics

Before using the tool, it helps to understand how Roman numerals work.

Roman Numeral Symbols and Their Values

Roman numerals are formed by combining these symbols according to specific rules.

Rules for Converting Roman Numerals to Numbers

1. Addition Rule

When a numeral of equal or smaller value follows another, the values are added.

Example:

• VIII = 5 + 1 + 1 + 1 = 8

• LX = 50 + 10 = 60

2. Subtraction Rule

When a smaller numeral comes before a larger one, it is subtracted.

Example:

• IV = 5 − 1 = 4

• IX = 10 − 1 = 9

3. Repetition Rule

Roman numerals can be repeated up to three times.

Example:

• III = 3

• XXX = 30

4. Invalid Combinations

Some symbols cannot be repeated or subtracted.

• V, L, and D cannot be repeated.

• I can subtract only from V and X

• X can subtract only from L and C

• C can subtract only from D and M

Our tool automatically validates these rules to ensure correct results.
