Roman Numerals
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000
How to Remember:
"M e D i C a L X a V I e r".
It has the roman numerals in descending order from 1000 to 1.
When a symbol appears after a larger (or equal) symbol, it is added:
Example: II = 2, (1 + 1 = 2) VI = 6, (5 + 1 = 6) XI = 11, (10 + 1 = 11)
But if a symbol appears before a larger symbol, it is subtracted:
Example: IV = 4, (5 - 1 = 4) IX = 9, (10 - 1 = 9)
Don't use the same symbol more than three times in a row:
Example: III = 3 VIII = 8 XXX = 30 LXXX = 80 CCC = 300 DCCC = 800 MMM = 3000
