Key Principles for Writing Roman Numerals
To write and understand Roman numerals, it is important to keep in mind the key principles:
- A larger letter preceding a smaller letter means their values are added together. For example, VIII (8) is written as V + I + I + I = 5 + 1 + 1 + 1.
- A smaller letter preceding a larger letter indicates that the smaller value is subtracted from the larger value. For example, IX (9) is written as X - I = 10 - 1.
- Letters can be repeated up to three times to represent the sum of their values. For example, III (3) represents 1 + 1 + 1.
- A letter should not be repeated more than three times in succession. Instead, subtractive notation is used for numbers such as 4 (IV) and 9 (IX).

Example 1: Convert XLVIII to an Arabic decimal number. To solve this problem, we need to break down the Roman numeral into its individual symbols and calculate their values. XLVIII can be broken down into: X = 10 L = 50 V = 5 III = 3 Adding up the values of each symbol, we get: 10 + 50 + 5 + 3 = 68. Therefore, XLVIII in Roman numerals is equivalent to 68 in Arabic decimal numbers.
Example 2: Convert LXXXIII to an Arabic decimal number. To convert this Roman numeral, we follow the same process as before. LXXXIII can be broken down into: L = 50 XXX = 30 III = 3 Adding up the values, we get: 50 + 30 + 3 = 83. Therefore, LXXXIII in Roman numerals is equivalent to 83 in Arabic decimal numbers.
Example 3: Convert XCI to an Arabic decimal number. To convert this Roman numeral, we follow the same process as before. XCI can be broken down into: X = 10 CI = 101 (Since CI represents 100 and I represents 1) Adding up the values, we get: 10 + 101 = 111. Therefore, XCI in Roman numerals is equivalent to 111 in Arabic decimal numbers.
