I would convert them back into Hindu-Arabic numerals, do the addition and then convert the answer to Roman numerals.
MD in Roman numerals adds up to 1500. M represents 1000 and D represents 500, so when combined, they equal 1500.
They could be Roman numerals that add up to 1000: DD = M
If you mean CD plus DC then in Roman numerals they add up to M meaning 400 plus 600 = 1000
Roman numerals can only go up to 4,999.
They could be 6 Roman numerals that add up to DC = 600

None because Big Ben is the name of a bell surrounded by 4 clocks.

roman numerals only go up to 1000, which is M
Cmxcix + dclxvi = mdclxvImproved answer in detail:-999 in Roman numerals: CM+XC+IX = IM666 in Roman numerals: DC+LX+VI = DCLXVI999+666 = IM+DCLXVI = MDCLXVNote that the Romans would have probably total up CM+XC+IX in the following manner:-CM+XC = XMXM+IX = IMMAnd that they would have probably total up DC+LX+VI in the following manner:-DC+LX = DCLXDCLX+VI = DCLXVITherefore it follows that:- IM+DCLXVI = MDCLXV (1665)Roman numerals:- M+1000, D=500, C=100, L=50, X=10, V=5 and I=1
With great difficulty because 1444 in Roman numerals in today's terms are MCDXLIV and to add them to DLV (555) is an almost impossible task. But the Romans probably calculated the above numbers on a abacus calculating board as:- MCCCCXXXXIIII + DLV = MDCCCCLXXXXVIIII = IMM (-1+2000=1999) when simplified. The rules governing today's Roman numeral system were not the same rules in which the Romans themselves actually used because they were changed in the Middle Ages presumably to make it easier to convert Roman numerals into Hindu-Arabic numerals that were gradually being introduced into Western Europe.
on converting the Arabic number into roman numerals we get that 300 in roman numerals is written as : CCC as C=100.
Roman numerals really only go up to a million.
