Frequently asked questions
How do you write 470 in Roman numerals?
Write 470 as CDLXX, combining CD + L + X + X. Start from the largest value that fits and work down until nothing is left over.
Why is 470 not written CCCCLXX?
CDLXX uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CCCCLXX breaks that rule, which is why CDLXX is the only correct form.
How is CDLXX broken down?
CDLXX breaks down as CD (400), L (50), X (10), X (10), so CD + L + X + X = 400 + 50 + 10 + 10 = 470.
What number is CDLXX?
CDLXX is 470. Read the symbols left to right, treat any smaller-before-larger pair as a single subtraction, and add the groups together.
