If you were to enumerate Roman numerals in the same format that most people wrongly use today then during the Roman era you'd probably have been thrown to the lions for misguiding the public. Today's rules governing the Roman numeral system were introduced during the Middle Ages and that was centuries after the Romans had retreated from England.
The ingenious Romans would have probably calculated 999,999 in the following logical and methodical manner:-
(CM)+(XC) = (XM)
(XM)+(IX) = (IM)
(IM)+CM = C(M)
C(M)+XC = X(M)
X(M)+IX = I(M) => -1+1,000,000 = 999,999
Hindu-Arabic conversion:-
900,000+90,000 = 990,000
990,000+9,000 = 999,000
999,000+900 = 999,900
999,900+90 = 999,990
999,990+9 = 999,999
For more complicated calculations the Romans would have used an abacus calculating device.

The way we write out Roman numerals today differs in the way that the ancient Romans actually did themselves and they would have probably wrote out the equivalent of 999,999 simply as I(M) which means 1,000,000-1
74 in Roman numerals is LXXIV 74 in Roman numerals would be LXXIV
In roman numerals 1,143 would be MCXLIII
999,999 would be written as (CMXCIX)CMXCIX.Improved Answer:The above answer is correct in terms of today's method of writing out Roman numerals but the Romans themselves in the past would have probably wrote out this number as I(C) meaning -1+100,000 = 999,999
No, MMMM does not equal 2020 in Roman numerals. In Roman numerals, M represents 1000, and repeating it four times would result in 4000. To represent 2020 in Roman numerals, it would be written as MMXX.
