Explicație pas cu pas:
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000
MDCCXXXVIII = M + D + C + C + X + X + X + V + I + I + I =
1000 + 500 + 100 + 100 + 10 + 10 + 10 + 5 + 1 + 1 + 1 =
1500 + 200 + 30 + 8 =
1738
XIV = X + IV =
10 + 4 =
14
CCCXXVIII = C + C + C + X + X + V + I + I + I =
100 + 100 + 100 + 10 + 10 + 5 + 1 + 1 + 1 =
300 + 20 + 8 =
328
MDXLII = M + D + XL + I + I =
1000 + 500 + 40 + 1 + 1 =
1500 + 40 + 2 =
1542
MCCCXCIX = M + C + C + C + XC + IX =
1000 + 100 + 100 + 100 + 90 + 9 =
1000 + 300 + 99 =
1399
CXXVII = C + X + X + V + I + I =
100 + 10 + 10 + 5 + 1 + 1 =
100 + 20 + 7 =
127
MCLVI = M + C + L + V + I =
1000 + 100 + 50 + 5 + 1 =
1000 + 100 + 56 =
