Cracking the Code of Roman Numerals: History, Meaning, and Modern Relevance
Have you ever looked at a clock face or a book chapter and wondered, ‘What’s with all those letters?’ Welcome to the world of Roman numerals, a number system that’s thousands of years old and still shows up in our everyday lives!
From ancient Roman stone carvings to modern wristwatches and Titles of Historical figures, Roman numerals have managed to stay timeless. At Universal Wisdom School, we love exploring the fascinating journey of such systems that connect history, mathematics, and logic in one go.
🏛️ What Are Roman Numerals?
Roman numerals are a numerical system used by ancient Romans that employ combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M, to represent numbers.
This system was used across the Roman Empire for dates, numbering, trading, and architecture, and remarkably, it’s still found in clocks, books, movie credits, and even tattoos today.
Here’s a quick overview:
| Symbol | Value |
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1000 |
These symbols form the foundation of all Roman numerals 1-100 and beyond.
A Little History Behind It (That’s Surprisingly Fun!)
Roman numerals originated around 500 B.C. and were influenced by the Etruscan numbering system. Unlike today’s base-10 (Arabic) numbers, Romans used letters and simple addition/subtraction rules.
Fun fact: Did you know the Colosseum in Rome still has numbers marked in Roman numerals above its arches? These were once used to identify seating sections, ancient ‘row numbers’ if you will! (Colosseum Rome Tickets, 2018)
Even today, Roman numerals continue to be taught in classrooms worldwide, not just for tradition, but for developing pattern recognition and historical literacy.
How to Read Roman Numerals
Here’s the golden rule:
Roman numerals are formed by combining letters and adding or subtracting their values.
| Rule | Example | Explanation |
| Add when a smaller numeral follows a larger one | VI = 6 | 5 + 1 = 6 |
| Subtract when a smaller numeral precedes a larger one | IV = 4 | 5 – 1 = 4 |
| Never repeat a numeral more than three times | III = 3, but 4 is IV | Keeps the system clean |
| Place larger numerals before smaller ones | LX = 60 | 50 + 10 |
To make it simple, just remember: ‘Add when it comes after, subtract when it comes before.’
Roman Numeral Chart (1-100)
Here’s how to write years in Roman numerals. Refer to this quick Roman numeral chart that students often find handy:
| Number | Roman Numeral | Number | Roman Numeral |
| 1 | I | 50 | L |
| 5 | V | 60 | LX |
| 10 | X | 70 | LXX |
| 20 | XX | 80 | LXXX |
| 30 | XXX | 90 | XC |
| 40 | XL | 100 | C |
💡 Try this as a classroom challenge: Write your birth year in Roman numerals, for instance, 2025 = MMXXV.
Rules to Remember (The Roman Numeral Grammar!)
Here’s a quick summary of Roman numeral rules for beginners:
| Rule | Example | |
| 1. | I, X, C, and M can be repeated up to 3 times | XXX = 30 |
| 2. | V, L, and D are never repeated | ❌ VV |
| 3. | Smaller numerals before larger ones mean subtraction | IX = 9 |
| 4. | Smaller numerals after larger ones mean addition | XI = 11 |
| 5. | Don’t subtract more than one numeral | 8 = VIII, not IIX |
These make excellent practice problems for grade 4 students, helping them build number sense through structure and reasoning.
Roman Numerals vs. Arabic Numbers
Let’s compare them side by side for clarity:
| Feature | Roman Numerals | Arabic Numbers (0-9) |
| Origin | Ancient Rome | India, popularized by Arabs |
| Base system | Non-positional | Base 10 positional |
| Zero | Does not exist | Exists |
| Example | IX = 9 | 9 |
| Ease of calculation | Harder | Easier |
| Usage today | Clocks, monuments, titles of generational historical figures | All mathematical operations |
Roman numerals may seem old-fashioned, but they beautifully represent how civilizations thought about numbers before zero even existed!

Why Do We Still Learn Roman Numerals?
Here’s a fun fact:
According to the National Curriculum Framework (NCERT, 2023), most schools in India introduce Roman numerals in Grades 3-5, not just for tradition, but because they help children:
- Understand numerical patterns
- Develop historical awareness
- Improve symbol recognition and sequencing
Roman numerals may no longer be used for everyday math, but they’re a valuable bridge between language and logic, and that’s what makes them fascinating!
Common Mistakes to Avoid
| ❌ Mistake | ✅ Correction |
| Writing IIII for 4 | Use IV |
| Using VV for 10 | Use X |
| Writing IC for 99 | Use XCIX |
| Forgetting order of subtraction | Always smaller before larger for subtraction |
Students must be encouraged to double-check their patterns, it’s the best way to master the rules of Roman numerals for kids.
Roman Numerals in Everyday Life
- Clock faces (Roman numerals clock designs)
- Monuments (cornerstones dated with Roman numerals)
- Books and movies (e.g., Rocky IV, Mission: Impossible VII)
- Royal names (Queen Elizabeth II, Pope John Paul II)
- Event names (Olympics XXIV, Super Bowl LVIII)
Each one reminds us that Roman numerals are history’s way of counting forward.
