1991
Under today's modern rules now governing the Roman numerals system MCMXCI represents 1991 but the ancient Romans would have worked it out quite differently.
On converting between Arabic and Roman Numbers ,we get : June 4 1991 IN ROMAN NUMERALS is written as : VI-IV-MCMXC1
M = 1000 C = 100 X = 10 I = 1 In Roman numerals the largest value letter is always to the left, except when a smaller value letter is to left of a larger value letter,; it then becomes subtraction. Hence M - 1000 CM = 1000 - 100 = 900 Hence MCM = 1000 + ( 1000 - 100) = 1900 Similrly XC = 100 - 10 = 90 So MCMXC = 1900 + 90 = 1990 MCMXCI = 1990 + 1 = 1991. NB As given in your question it is NOT MCMXC1 but MCMXCI.. It is a capital letter 'I', NOT a number '1'.
