1 = I, 5 = V, 10 = X, 50 = L, 100 = C and 500 = D. Any number from 1 to 500 can be written using a combination of these numbers, for example, 374 would be CCCLXXIV.
499 in Roman numerals: CDICToday it is written out as: CDXCIXBut during the Roman era it was most probably wrote as: ID (-1+500 = 499)
The number 1 is written as I (capital i) in Roman numerals. Other Roman numerals you may be inyerested in: V = 5; X = 10; L = 50; C = 100; D = 500; M = 1000.
Here is the table of Roman Numerals. M = 1000 D = 500 C = 100 L = 50 X = 10 V = 5 ( THe answer to your question). I = 1
514 written as a Roman Numeral is DXIV which is 500+10+(5-1)=514
A Roman Numeral can be written by using capital letters. The basic Roman Numerals are: I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000).
1006 in Roman numerals is MVIDDVI (500+500+5+1 = 1006) but 1006 in Roman numerals is normally MVI (1000+5+1 = 1006)
D in Roman numerals is equal to 500 at one time 500 was expressed as I) meaning 1*500 over time they were merged to today's D.
M=1000, D=500, I=1. So, 1501 is equal to MDI in Roman numerals.
1000 = m 500 = d 1500 = md
(v)i = 1000*5+1 = 5001
dcccxviii (in capital letters) 500+100+100+100+10+5+1+1+1
500 is D, 100 is C, 10 is X, 5 is V and 1 is I. This would be written as DCCCXXVIII.
