How to Write Roman Numerals from 1 to 100?
There are two methods to write Roman numerals:
Method 1: Breaking Down the Number:
Break the number into parts, write their Roman numeral equivalents, and add them.
Example: 65 = 50 + 10 + 5 = L + X + V = LXV
Method 2: Grouping Numbers:
Group the numbers and then add the Roman numerals.
Example: 65 = 60 + 5 = LX + V = LXV
Rules for Writing Roman Numerals
- Addition Rule: When a larger letter precedes a smaller letter, add them.
Example: CX = 100 + 10 = 110 - Subtraction Rule: When a smaller letter precedes a larger letter, subtract the smaller from the larger.
Example: IV = 5 – 1 = 4 - Repetition Rule: Letters can be repeated up to three times to add their values.
Example: XXX = 10 + 10 + 10 = 30
- Non-Repetition Rule: Letters V, L, and D cannot be repeated.
Examples of Roman Numerals Calculations
- Example 1: Find the product of XVIII and LXX
- XVIII = 18, LXX = 70
- 18 × 70 = 1260
- 1260 = MCCLX
- Example 2: Find the value of LXXVII – XIII
- LXXVII = 77, XIII = 13
- 77 – 13 = 64
- 64 = LXIV
- Example 3: What is the value of LXVI?
- LXVI = 66
Learning Roman numerals from 1 to 100 is straightforward with these methods and rules, making it easy to understand and convert numbers.
