0ROMAN NUMERALS
The Roman numeral system uses seven symbols:
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000
Roman numerals are read from left to right, starting with the symbol representing the largest value.
Rules:
- The same symbol cannot occur continuously more than three times.
- The value of the numeral is the sum of the values of the symbols.
For example LX VII = 50 + 10 + 5 + 1 + 1 = 67.
An exception to the left to the right reading occurs when a
symbol of smaller value is followed immediately by a symbol of
greater value, then the smaller value is subtracted from the
larger. For example.
CDXL VIII = (500 – 100) + (50 – 10) + 5 + 1 + 1 + 1 = 448.
