What Are Roman Numerals?
Roman numerals are a number system used in ancient Rome. Instead of the digits we use today (0–9), Roman numerals use combinations of letters to represent numbers.
There are seven basic Roman numeral symbols:
| Roman Numeral | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1,000 |
Once you know these seven symbols and a few simple rules, you can read and write many different numbers using Roman numerals.
For example, the number 12 is written as XII. X represents 10, and each I represents 1.
10 + 1 + 1 = 12.
But Roman numerals aren’t always as simple as adding numbers together. Sometimes you have to subtract!
How to Read Roman Numerals
There are two important rules to understand when reading Roman numerals.
Rule 1: Add When a Smaller Numeral Comes After a Larger One
When a symbol of equal or smaller value comes after another symbol, you add its value.
For example:
- VI = 5 + 1 = 6
- VIII = 5 + 1 + 1 + 1 = 8
- XV = 10 + 5 = 15
- XXIII = 10 + 10 + 1 + 1 + 1 = 23
- LX = 50 + 10 = 60
Rule 2: Subtract When Certain Smaller Numerals Come Before Larger Ones
Sometimes a smaller numeral comes before a larger one. This tells you to subtract.
For example:
- IV = 5 − 1 = 4
- IX = 10 − 1 = 9
- XL = 50 − 10 = 40
- XC = 100 − 10 = 90
- CD = 500 − 100 = 400
- CM = 1,000 − 100 = 900
There are specific rules about which numerals can be subtracted:
- I can come before V or X.
- X can come before L or C.
- C can come before D or M.
For example, 49 is written as XLIX, not IL.
XL = 40 and IX = 9.
40 + 9 = 49.
Rule 3: Don’t Repeat a Symbol More Than Three Times in a Row
In the standard Roman numeral system taught today, I, X, C, and M can be repeated up to three times in a row.
For example:
- II = 2
- III = 3
- XX = 20
- XXX = 30
- CCC = 300
But 4 is written as IV, not IIII, and 40 is XL, not XXXX.
The symbols V, L, and D are not repeated in standard notation.
Fun fact: Some traditional clocks use IIII instead of IV for the number 4! Historical Roman numeral usage wasn’t always as standardized as the rules we teach today.
Roman Numerals 1–20
Here’s a handy reference for the first 20 Roman numerals.
| Number | Roman Numeral | Number | Roman Numeral |
|---|---|---|---|
| 1 | I | 11 | XI |
| 2 | II | 12 | XII |
| 3 | III | 13 | XIII |
| 4 | IV | 14 | XIV |
| 5 | V | 15 | XV |
| 6 | VI | 16 | XVI |
| 7 | VII | 17 | XVII |
| 8 | VIII | 18 | XVIII |
| 9 | IX | 19 | XIX |
| 10 | X | 20 | XX |
Once children understand the pattern, they can continue counting beyond 20.
Roman Numerals 1–100 and Beyond
You don’t have to memorize every Roman numeral up to 100 or 1,000. You can build larger numbers using the same seven symbols and the addition and subtraction rules.
Here are some helpful examples:
| Number | Roman Numeral |
|---|---|
| 25 | XXV |
| 30 | XXX |
| 40 | XL |
| 49 | XLIX |
| 50 | L |
| 75 | LXXV |
| 90 | XC |
| 99 | XCIX |
| 100 | C |
| 250 | CCL |
| 500 | D |
| 900 | CM |
| 1,000 | M |
| 1,500 | MD |
| 2,000 | MM |
| 2,026 | MMXXVI |
Let’s try a larger number.
How do you write 1984 in Roman numerals?
Break it into place values:
- 1,000 = M
- 900 = CM
- 80 = LXXX
- 4 = IV
Put them together:
1984 = MCMLXXXIV
This is a great way to practice place value while learning a completely different number system!
History of Roman Numerals
Roman numerals developed in ancient Italy and became widely used by the Romans. Their origins are connected to earlier counting and numeral traditions, including those of the Etruscans.
The system was in use centuries before the height of the Roman Empire and continued to be used throughout Europe long after the Western Roman Empire fell.
Roman numerals were useful for recording quantities, marking dates, numbering events, and keeping records.
You can still find Roman numerals carved into ancient monuments and buildings.
Why Did People Stop Using Roman Numerals?
Roman numerals were widely used for centuries, but they have some limitations. For one thing, the standard Roman numeral system doesn’t have a symbol for zero. And while you can add, subtract, multiply, and divide quantities represented by Roman numerals, performing written calculations with the notation is much less convenient than using our modern place-value system.
The Romans did have ways to represent fractions, including a system based on twelfths. However, these were different from the familiar fraction notation we use today.
The Hindu-Arabic numeral system, which developed in India and spread through the Islamic world, gradually became more common in Europe during the Middle Ages and afterward. Its use of place value and zero made written arithmetic much easier.
Today, we use Hindu-Arabic numerals for most everyday calculations, but Roman numerals haven’t disappeared!
Where Do We Still Use Roman Numerals Today?
Challenge your kids to look for Roman numerals in everyday life. You might be surprised how many places you find them!
- Clocks and Watches- Some clocks use Roman numerals instead of regular numbers. Look for I through XII around the clock face.
- Buildings and Monuments- Roman numerals are sometimes carved into buildings to show the year they were constructed.
- Books and Chapters- You may see Roman numerals used for chapter numbers, introductory pages, or book volumes.
- The Super Bowl- The Super Bowl is numbered using Roman numerals. For example, Super Bowl LX represents the 60th Super Bowl.
- Kings, Queens, and Popes- Roman numerals distinguish rulers and religious leaders who share the same name, such as Elizabeth II or Louis XIV.
- Movie Titles and Sequels- Some movie titles use Roman numerals to indicate sequels or installments in a series.
- The Olympic Games- Roman numerals have also been used in the official numbering of the modern Olympic Games.
Fun Ways to Practice Roman Numerals
Once children understand the basic rules, try some hands-on activities to help them practice.
1. Roman Numeral Scavenger Hunt
Challenge children to find Roman numerals around their home, school, or community. Look at clocks, book pages, building dates, movie titles, and historical photographs. Have them record each Roman numeral they discover and translate it into a regular number.
2. Roman Numeral Clock Challenge
Draw a large clock face with 12 empty spaces. Challenge children to fill in the correct Roman numerals from I to XII. For an extra challenge, have them create their own Roman numeral clock using a paper plate.
You could also compare the IV and IIII versions of the number 4 and discuss why different clocks might use different forms.
3. Roman Numeral Number Hunt
Give children a number, such as 49, 76, or 125. Have them use their Roman numeral chart to figure out how to write it. Then reverse the activity! Write a Roman numeral on the board and challenge children to decode it.
Try these:
- XXIV
- XLVIII
- LXXIX
- CXL
- MMXXVI
Answers: 24, 48, 79, 140, and 2026.
4. Build Roman Numerals With Craft Sticks
Use craft sticks or strips of paper to create the letters I, V, X, L, C, D, and M. Challenge children to build different numbers and explain how they know their answers are correct.
You can also make a matching game by pairing Roman numerals with their regular number equivalents.
5. Roman Numeral Secret Codes
Write a secret message using Roman numerals to represent letters of the alphabet. For example, use I for A, II for B, III for C, and so on through XXVI for Z. Children can use their Roman numeral charts to decode the message.
This is a fun way to combine number recognition with problem-solving!
Note: This is a modern code activity using Roman numerals, not a historical Roman writing system.
