Frequently asked questions
How do you write 480 in Roman numerals?
Write 480 as CDLXXX, combining CD + L + X + X + X. Start from the largest value that fits and work down until nothing is left over.
Why is 480 not written CCCCLXXX?
CDLXXX uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CCCCLXXX breaks that rule, which is why CDLXXX is the only correct form.
How is CDLXXX broken down?
CDLXXX breaks down as CD (400), L (50), X (10), X (10), X (10), so CD + L + X + X + X = 400 + 50 + 10 + 10 + 10 = 480.
What number is CDLXXX?
CDLXXX is 480. Read the symbols left to right, treat any smaller-before-larger pair as a single subtraction, and add the groups together.
