Roman Numerals

I=1

V=5

X=10

L=50

C=100

D=500

M=1000

RULES

1.When a symbol appears after a larger (or equal) symbol it is added Example: VI = V + I = 5 + 1 = 6 Example: LXX = L + X + X = 50 + 10 + 10 = 70

2.But if the symbol appears before a larger symbol it is subtracted Example: IV = V − I = 5 − 1 = 4 Example: IX = X − I = 10 − 1 = 9

3. Don't use the same symbol more than three times in a row (but IIII is sometimes used for 4, particularly on clocks) but it is wrong and you are meant to right it like this IV
