## Roman Numerals
|
|
|
|
I = 1 <br>
|
|
V = 5 <br>
|
|
X = 10 <br>
|
|
L = 50 <br>
|
|
C = 100 <br>
|
|
D = 500 <br>
|
|
M = 1000 <br>
|
|
|
|
How to Remember:<br>
|
|
"M e D i C a L X a V I e r".<br>
|
|
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:
|
|
<pre>
|
|
<b>Example:</b>
|
|
II = 2, (1 + 1 = 2)
|
|
VI = 6, (5 + 1 = 6)
|
|
XI = 11, (10 + 1 = 11)
|
|
</pre>
|
|
|
|
But if a symbol appears before a larger symbol, it is subtracted:
|
|
<pre>
|
|
<b>Example:</b>
|
|
IV = 4, (5 - 1 = 4)
|
|
IX = 9, (10 - 1 = 9)
|
|
</pre>
|
|
|
|
Don't use the same symbol more than three times in a row:
|
|
<pre>
|
|
<b>Example:</b>
|
|
III = 3
|
|
VIII = 8
|
|
XXX = 30
|
|
LXXX = 80
|
|
CCC = 300
|
|
DCCC = 800
|
|
MMM = 3000
|
|
</pre>
