MDCCCXCI is in roman numerals. In normal numbers, it is:M = 1000, D = 500, C = 100, X = 10 and I = 1 so MDCCCXCI = 1000 + 500 + 100 + 100 + 100 + (100 - 10) + 1 = 1891.

The numbers are written like this: 1=I, 10=X 100=C 1000=M.
MDCCCXCI is in roman numerals. In normal numbers, it is:M = 1000, D = 500, C = 100, X = 10 and I = 1 so MDCCCXCI = 1000 + 500 + 100 + 100 + 100 + (100 - 10) + 1 = 1891.

If you mean: 15 10 100 and 1000 then they are XV X C and M respectively
It is: 1000+1000+100+100+10+10+1 = 2221
