Here's a step-by-step guide on how to write MCMXCI in numbers:
MCMXCI = M + (M – C) + (C – X) + I
MCMXCI = 1000 + (1000 – 100) + (100 – 10) + 1
MCMXCI = 1991
Why should 1991 be written as MCMXCI?
In Roman numerals, 1000 is written as M, 900 is written as CM, 90 is written as XC and 1 is written as I. Hence, 1991 = M + CM + XC + I = MCMXCI.
Find 2000 – 9.
2000 – 9 = 1991. Hence, 2000 – 9 is 1991 which is written as MCMXCI in Roman numerals.
Find the remainder we get when MCMXCI is divided by X.
MCMXCI = 1991 and X = 10 in Roman numerals. So the remainder we get when MCMXCI is divided by X is I.
