Roman Numerals

TermDefinition
I 1 - One
V 5 - Five
X 10 - Ten
L 50 - Fifty
C 100 - One Hundred
D 500 - Five Hundred
M 1,000 - One Thousand
SS 1/2 – Half
If one or more letters are placed after another letter of greater value, add that amount. Example: X V I = (10 +5 +1)
If a letter of lower value is placed before another letter of greater value, the lower value is subtracted from the higher value. Example: I X = (10 - 1)
First look for and do the subtractions, then add together the remaining values. Example: C L X I V Subtractions first = C L X + (I V) Add remaining values = C L X + (4) Translated = 100+50+10+(4) Answer = 164
A letter can only repeat three times. For example the number 8 is VIII, and the number 9 is IX. (Not VIIII) Another example: the number 30 is XXX, and 40 is XL. (Not XXXX)
V, L and D are never subtracted or repeated.
