324 in Roman Numerals

Frequently asked questions
How do you write 324 in Roman numerals?
Write 324 as CCCXXIV, combining C + C + C + X + X + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 324 not written CCCXXIIII?
CCCXXIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CCCXXIIII breaks that rule, which is why CCCXXIV is the only correct form.
What are 323 and 325 in Roman numerals?
323 is CCCXXIII and 325 is CCCXXV. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is CCCXXIV broken down?
CCCXXIV breaks down as C (100), C (100), C (100), X (10), X (10), IV (4), so C + C + C + X + X + IV = 100 + 100 + 100 + 10 + 10 + 4 = 324.
