Understanding Roman Numerals
Roman numerals are based on a combination of letters from the Latin alphabet. Each letter holds a specific value:
– I = 1
– V = 5
– X = 10
– L = 50
– C = 100
– D = 500
– M = 1000
Basic Principles of Roman Numerals
- Addition: When smaller numbers precede larger numbers, they are added. For instance, VI = 5 + 1 = 6.
- Subtraction: When a smaller number precedes a larger number, it is subtracted. For example, IV = 5 – 1 = 4.
Examples of Common Roman Numerals
