How this list was compiled: Numerals are facts no one owns; the sets and the line under each answer are our own. Checked on 2026-09-30: every numeral is computed from its number and read back to the same number. The seven symbols and their values (I 1, V 5, X 10, L 50, C 100, D 500, M 1000), the rule that a smaller symbol before a larger one is taken away (IV, IX, XL, XC, CD, CM) and 3,999 as the largest number the standard form can write: https://en.wikipedia.org/wiki/Roman_numerals. The seven symbol values were also compared with the Roman numeral entries of the Unicode character names list, https://www.unicode.org/Public/UCD/latest/ucd/NamesList.txt. Licence: own work

How it works

These Roman numeral flash cards show a numeral such as XIV on the front. The back gives the number and how it is built: X + IV = 10 + 4. Five sets run from I to MMMCMXCIX.

Read the full guide

Five sets, from I to MMMCMXCIX

The page opens on 1 to 10. Under Show only, 11 to 20 adds the teens, Tens runs X, XX, XXX to C, and Hundreds runs C to M, where D is 500 and M is 1000. The Mixed set holds twelve longer numerals, such as XLIX for 49 and MCMXCIX for 1999.

Print 12 cards to a sheet

Pick a set, turn a card and press the print button under the card. Each set fits one sheet of Letter or A4. Print double-sided and flip on the long edge, so 14 lands behind XIV.

  • Seven symbols write every numeral: I is 1, V 5, X 10, L 50, C 100, D 500 and M 1000.
  • A smaller symbol before a larger one is taken away: IV is 4 and IX is 9. After it, it is added: VI is 6.
  • Read a long numeral in chunks from the left. MCMXCIX is M, CM, XC, IX: 1000 + 900 + 90 + 9.

Questions and answers

How do you read Roman numerals?

Add the symbols from left to right, largest first: XVI is 10 + 5 + 1, or 16. When a smaller symbol stands before a larger one, take it away: XIV is 10 + 4, because IV is 5 take away 1.

What is the largest Roman numeral?

In the standard form, 3,999, written MMMCMXCIX. It is the last card in the Mixed set. Larger numbers have been written in other ways over time.

Why is 4 written IV and not IIII?

IV is the usual form: I before V means 5 take away 1. IIII is also seen, and many clock faces with Roman numerals still use IIII for four while keeping IX for nine.

What does quiz mode accept?

The number in digits: 14 for XIV. Words such as fourteen are not marked; the page asks for digits.
