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.
The number 555 in Roman Numerals is DLV. D=500 L=50 V=5
DLV = 555
The number 555 in Roman Numerals is DLV. D=500 L=50 V=5
It is: (DLV)DLV meaning 1,000*555+555 = 555,555
I don't think it's acceptable to precede a D with an L or to have more that one D in a number. However, putting that aside and following the basic addition and subtraction rules for Roman numerals, I would say it is a sloppy way of expressing 1055. D = 500 "LD = 500 - 50 = 450" C = 100 V = 5 500 + 450 + 100 + 5 = 1055 The proper way to express 1055 in Roman numerals is MLV.

The Babylons made great advancements in mathematics for example the numerals 5,55 ,and 555 have different values.:)
In today's modern notation: DLIV = 554 and DLV = 555
In 555 the emperor Justinian conquered many former territories of the Western Roman Empire. Pope Vigilius died on the way back to his home in Syracuse.
That is entirely dependant on the speed you are driving at. At one mile per hour it would take 555 hours to drive 555 miles, while at 555 miles per hour it would only take one hour.
555 + 555 = 1110
