Roman Numeral math
Lesser
value follows greater value:
LX =
50
+ 10 = 60
MDC =
1000
+ 500 + 100 = 1600
Greater

XL =
50
- 10 = 40
XLV=
(50
– 10) + 5 = 45
Lesser
value between two greater value:
XVL =
10
+ (50 – 5) = 55
MLC =
1000
+ (100 – 50) = 1050
Letters
arranged in decreasing order except for letters
having values to be subtracted from next letter:
MCMXLIV=
1000+(1000–100)+(50-10)+4
