| M | 1000 |
| MM | 2000 |

Roman Numeral Basics (Quick Refresher)

| Roman Numeral | Value |

How M Is Used in Roman Numerals
1. As a Standalone Number
- M = 1,000
Simple, clear, and powerful.
2. Repeated to Show Larger Numbers
Roman numerals rely on repetition:
- MM = 2,000
- MMM = 3,000
Traditionally, Roman numerals don’t repeat a symbol more than three times, which limits how large numbers are written.
3. Combined with Other Numerals
Examples:
- MC = 1,100
- MD = 1,500
- MCM = 1,900
- MMXXIV = 2024
Example Table: Numbers Using M
| Roman Numeral | Arabic Number | Explanation |
| M | 1,000 | Base value |
| MI | 1,001 | M + I |
| MC | 1,100 | M + C |
| MD | 1,500 | M + D |
| MCM | 1,900 | 1,000 + (1,000 − 100) |
| MM | 2,000 | M repeated |
| MMXXIV | 2024 | Modern year example |
How Subtraction Works with M
Roman numerals sometimes use subtractive notation to avoid repetition.
Key Rule
A smaller numeral placed before a larger one is subtracted.
Examples:
- CM = 900 (1,000 − 100)
- MCM = 1,900
- CMXC = 990
This system makes Roman numerals more compact and elegant.

2. Clock Faces
