How to write 104 in Roman numerals
Build 104 from these Roman groups, read from left to right: C, IV. Each row below gives the value contributed by one group. Join the groups to obtain CIV.
| Roman group | Calculation | Value |
|---|---|---|
| C | 100 | 100 |
| IV | (5 − 1) | 4 |
100 + 4 = 104.
About the number 104
104 is an even positive integer. Its decimal representation has 3 digits, and their sum is 5. These properties describe the numerical value, which stays the same when it is written in Roman notation.
Decimal place values
104 = 100 + 4. These are the nonzero place-value terms. Decimal positions and Roman groups work differently: Roman letters carry fixed base values, with subtraction pairs and overlines modifying how the groups are evaluated.
Reading CIV correctly
This numeral contains IV. IV represents 4 before any overline multiplier. Keep each pair together when reading the value; reversing its letters changes the calculation.
An overline is not needed for this number. Adding one would multiply the marked value by 1000. For the general notation rules, see the Roman numerals guide or MathWorld’s Roman numeral reference (opens in a new tab).
Practice Roman numerals
Choose a range and practise new numbers. Each question counts once. Changing the range or direction starts a new session.
Use modern Roman notation. For thousands, type (IV) for 4000 or paste I̅V̅. Lowercase letters are accepted. When reading a Roman numeral, answer with a whole number. These are personal practice results.
