The way we now notate Roman numerals today differs in the way that the ancient Romans actually notated them which would have probably been in the following format:-
1 to 9: I II III IIII V VI VII VIII and VIIII
10 to 90: X XX XXX XXXX L LX LXX LXXX LXXXX
400 and 500: CCCC and D
To select a given numeral simply write it down in descending order as for example 435 = CCCCXXXV
It is: 500 = D as a Roman numeral
500 = D
D = 500
DCC = 500+100+100 = 700
500 = D 1,000 = M
It is: 500 = D as a Roman numeral
D is 500 in Roman numerals.
500 = D
D = 500
DCCLXVIII Decoded from classical Roman counting into modern Arabic numeral notation: D = 500 C = 100 L = 50 X = 10 V = 5 I = 1
DCC = 500+100+100 = 700
500 = D 1,000 = M
On converting between Arabic and Roman Numbers ,we get : 500 IN ROMAN NUMERALS is written as : D
D
401
Roman ' D ' = 500.For a number over 500, write ' D ', then follow it with the amount over 500.For example:To write 511, (recalling that ' X ' = 10, and ' I ' = 1),D X I
((D)) = 10,000*500 = 5,000,000
