    Twenty quizzes on Roman numerals

    Roman Numerals is the collection for testing what you know about I, V, X, L, C, D and M: twenty Roman numerals quizzes that start from the seven symbols and go all the way to years, dates and numbers with a bar over them. After every answer there is an explanation, with the rule you need to stop making the same mistake.

    The classic traps

    These are the questions almost everyone trips on: why 49 is not written IL, why 99 is not IC, why the 4 on clocks is often IIII. There are two quiz types: Classic, with four answers to choose from, and Yes or No.

    A Special collection

    This is one of our Special collections: the first quiz is open to everyone, and the others need a free account. And if you like Roman history, try the Roman Empire collection too.

    Questions about Roman Numerals, with answers

    What are the seven symbols of Roman numerals?

    I is 1, V is 5, X is 10, L is 50, C is 100, D is 500 and M is 1,000. Every other number is made by combining them.

    How do you write 49 in Roman numerals?

    XLIX, which is 40 (XL) plus 9 (IX). IL is wrong: the I goes in front of V and X only.

    Why is the 4 on clocks written IIII?

    It is a clockmaking tradition. The most cited explanation is that IIII visually balances the VIII on the opposite side of the dial. Outside of clocks, 4 is written IV.

    How do you write 1999 in Roman numerals?

    MCMXCIX: M (1,000) plus CM (900) plus XC (90) plus IX (9).

    What is the largest Roman numeral?

    With the seven letters and the modern rules, you can reach 3,999, MMMCMXCIX. With a bar over a letter, which multiplies it by a thousand, you can go much higher.

    Frequently asked questions

    How many quizzes are in Roman Numerals?

    Twenty: thirteen Classic and seven Yes or No, from easiest to hardest.

    Is the collection free?

    It costs nothing, but it is one of our Special collections: the first quiz is open to everyone, and the other nineteen need a free account.

    Is it right for elementary school?

    Yes, the first quizzes suit children from third grade. The last ones, on centuries, dates and the bar over the letters, are meant for people who already know the rules.

    How do I read a Roman numeral?

    Read from left to right and add the values. If a smaller symbol comes right before a bigger one, subtract it instead: IV is 5 − 1 = 4 and XL is 50 − 10 = 40.
