666 in Roman numerals is DCLXVI. To convert 666 in Roman Numerals, we will write 666 in the expanded form, i.e. 666 = 500 + 100 + 50 + 10 + 5 + 1 thereafter replacing the transformed numbers with their respective roman numerals, we get 666 = D + C + L + X + V + I = DCLXVI.

The transformed roman numerals, MMXIII = MM + X + III = 2000 + 10 + 3 = 2013, can be expressed as numbers by combining the transformed roman numerals. The translation of MMXIII Roman Numerals is correct since the higher roman numbers come before the lower numerals.

Numbers in the teens, twenties and thirties follow the same form as the first set, only with X's indicating the number of tens. So XXXI is 31, and XXIV is 24. L. L means 50. Based on what you've learned, I bet you can figure out what 40 is.

Roman number system does not contain the number zero. The roman number system was basically designed to estimate the prices of goods and trading business. So the roman system did not need any value to represent zero. But instead of zero, the word nulla was used by the Romans to specify zero.
