CCVIII = 100 + 100 + 5 + 1 + 1 + 1 = 208

General Roman numerals.

If a lower number precedes a higher number then subtract the lower number from the higher number.
Example XC = 90 (100 - 10), IX = 9 (10 - 1)

1. 100 + 50 + 10 + 5 = 165
2. 100 + 50 + 4(5 - 1) = 154
3. 100 + 100 + 5 + 3 = 208

1. CLXV = 165
2. CLIV - 144
3. CCVIII = 208

C=100
L=50
X=10
V=5

CLXV=165
CLIV=154
CCVIII=208
