Exploring Roman Numerals

Introduction to Roman Numerals

• Roman numerals are a numeral system that originated in ancient Rome.

• They are based on a combination of letters from the Latin alphabet.

• Each letter represents a specific value, and when combined, they create different numbers.

• Some common Roman numerals include I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

• Understanding Roman numerals is important for historical and cultural references, as well as for solving puzzles and deciphering ancient inscriptions.

Subtractive Notation

Trivia: Roman numerals use subtractive notation for years. This means that a smaller numeral placed before a larger one is subtracted from the larger one. For example, IV represents 4 (5-1) and CM represents 900 (1000-100). This system was used to avoid repeating the same numeral more than three times in a row, which was considered bad luck.

To Write Time in Roman Numerals follow these steps:

2. Separate the hour and minute with a Colon.
So, it looks like V:

3. Write the Minutes in Roman numerals.
If its 25 minutes past the hour, write it as XXV (25 in Roman numerals).

4. Put them Together!
For 5:25, write V:XXV.

For example the commonly used system in the Philippines is Month-Date-Year Format which will change the answer in the example to
X-VII-MMXXIII.
