Frequently asked questions
How do you write 964 in Roman numerals?
Write 964 as CMLXIV, combining CM + L + X + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 964 not written CMLXIIII?
CMLXIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CMLXIIII breaks that rule, which is why CMLXIV is the only correct form.
What are 963 and 965 in Roman numerals?
963 is CMLXIII and 965 is CMLXV. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is CMLXIV broken down?
CMLXIV breaks down as CM (900), L (50), X (10), IV (4), so CM + L + X + IV = 900 + 50 + 10 + 4 = 964.
