Frequently asked questions
How do you write 740 in Roman numerals?
Write 740 as DCCXL, combining D + C + C + XL. Start from the largest value that fits and work down until nothing is left over.
Why is 740 not written DCCXXXX?
DCCXL uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. DCCXXXX breaks that rule, which is why DCCXL is the only correct form.
How is DCCXL broken down?
DCCXL breaks down as D (500), C (100), C (100), XL (40), so D + C + C + XL = 500 + 100 + 100 + 40 = 740.
What number is DCCXL?
DCCXL is 740. Read the symbols left to right, treat any smaller-before-larger pair as a single subtraction, and add the groups together.
