3. A bar on a Roman Numeral means multiplying that Number by 1000.4. If large numbers come before the smaller ones , they are added.
2. "M" (Mille) ---> Thousand
3. A bar on a Roman Numeral means multiplying that Number by 1000.4. If large numbers come before the smaller ones , they are added.
E.g. VI = 5 + 1 = 6 (bcuz V = 5 ; I =1)
LX = 50 + 10 = 60
5. If smaller numbers come before the larger ones, they are subtracted.
E.g. IV = V - I = 5 - 1 = 4
XL = L - X = 50 - 10 = 40
6. No digit is repeated more than thrice.
E.g. CXXXX =140 (x) ; CXL =140 (✓)
7. "V " , "L" and "D" (all these Numerals are starting will 5) are never subtracted.
8. "I" can be subtracted from "V" and "X" , once only .
9. "X" can be subtracted from "L" and "C" , once only.
10. "C" can be subtracted from "D" and "M", once only.
