What is ccxc in Roman Numerals?

Answer 1

CCXC in Roman numerals represents the number 290 Add together the individual numerals (M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, I = 1) unless a smaller numeral precedes a larger one in which case subtract it from the larger one.

→ CCXC = 100 + 100 + (-10 + 100) = 290.

Answer 2

C represents 100 and X is 10. Because the X comes before the C you subtract it and this would be shown as 290.
