Frequently asked questions
How do you write 970 in Roman numerals?
Write 970 as CMLXX, combining CM + L + X + X. Start from the largest value that fits and work down until nothing is left over.
Why is 970 not written DCCCCLXX?
CMLXX uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. DCCCCLXX breaks that rule, which is why CMLXX is the only correct form.
How is CMLXX broken down?
CMLXX breaks down as CM (900), L (50), X (10), X (10), so CM + L + X + X = 900 + 50 + 10 + 10 = 970.
What number is CMLXX?
CMLXX is 970. Read the symbols left to right, treat any smaller-before-larger pair as a single subtraction, and add the groups together.
