Basic Rules to Interpret Roman Numerals

1. Addition with Larger Preceding Smaller

• When a larger numeral precedes a smaller one, their values are added.
  • Example: MC = 1000 (M) + 100 (C) = 1100

2. Subtraction with Smaller Preceding Larger

• When a smaller numeral precedes a larger one, the smaller value is subtracted from the larger one.
  • Example: CD = 500 (D) – 100 (C) = 400

3. Repetition for Addition

• Repeating a numeral adds its value each time.
  • Example: II = 1 (I) + 1 (I) = 2

4. Limit on Repetition

• The same numeral cannot be repeated more than three times in a row.
