## 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 to represent numbers such as 4 (IV) and 9 (IX).

## Problem Examples for I Roman Numerals

Here are a few examples of Roman numeral conversion problems involving I:

Example 1: Convert IX to an Arabic decimal number. To solve this problem, we break down the Roman numeral into its individual symbols and calculate their values. IX can be broken down into: I = 1 X = 10 Adding up the values of each symbol, we get: 1 + 10 = 11. Therefore, IX in Roman numerals is equivalent to 11 in Arabic decimal numbers.

Example 2: Convert XIV to an Arabic decimal number. To convert this Roman numeral, we follow the same process as before. XIV can be broken down into: X = 10 IV = 4 Adding up the values, we get: 10 + 4 = 14. Therefore, XIV in Roman numerals is equivalent to 14 in Arabic decimal numbers.

Example 3: Convert XXI to an Arabic decimal number. To convert this Roman numeral, we follow the same process as before. XXI can be broken down into: X = 10 I = 1 Adding up the values, we get: 10 + 1 = 11. Therefore, XXI in Roman numerals is equivalent to 11 in Arabic decimal numbers.

Example 1: Convert IX to an Arabic decimal number. To solve this problem, we break down the Roman numeral into its individual symbols and calculate their values. IX can be broken down into: I = 1 X = 10 Adding up the values of each symbol, we get: 1 + 10 = 11. Therefore, IX in Roman numerals is equivalent to 11 in Arabic decimal numbers.

Example 2: Convert XIV to an Arabic decimal number. To convert this Roman numeral, we follow the same process as before. XIV can be broken down into: X = 10 IV = 4 Adding up the values, we get: 10 + 4 = 14. Therefore, XIV in Roman numerals is equivalent to 14 in Arabic decimal numbers.

Example 3: Convert XXI to an Arabic decimal number. To convert this Roman numeral, we follow the same process as before. XXI can be broken down into: X = 10 I = 1 Adding up the values, we get: 10 + 1 = 11. Therefore, XXI in Roman numerals is equivalent to 11 in Arabic decimal numbers.
