I=1
V=5
X=10
L=50
C=100
D=500
M=1000

Add each number if their value decrease from left to right. Eg: MCXVI=1000+100+10+5+1=1116
Subtract their value if their value increase. Eg: CIX= 100+10-1=109

I (http://en.wikipedia.org/wiki/I) or i 1 or one (http://en.wikipedia.org/wiki/1_%28number%29) (unus)
V (http://en.wikipedia.org/wiki/V) or v 5 or five (http://en.wikipedia.org/wiki/5_%28number%29) (quinque)
X (http://en.wikipedia.org/wiki/X) or x is10 or ten (http://en.wikipedia.org/wiki/10_%28number%29) (decem)
L (http://en.wikipedia.org/wiki/L) or l is 50 or fifty (http://en.wikipedia.org/wiki/50_%28number%29)
C (http://en.wikipedia.org/wiki/C) or c is 100 or one hundred (http://en.wikipedia.org/wiki/100_%28number%29) (centum)
D (http://en.wikipedia.org/wiki/D) or d is 500 or five hundred (http://en.wikipedia.org/wiki/500_%28number%29)
M (http://en.wikipedia.org/wiki/M) or m is 1000 or one thousand (http://en.wikipedia.org/wiki/1000_%28number%29) (mille)

For large numbers (five thousand (http://en.wikipedia.org/wiki/5000_%28number%29) and above), a bar is placed above a base numeral to indicate multiplication (http://en.wikipedia.org/wiki/Multiplication) by 1000:

an underline X (X) is ten million

Rules regarding Roman numerals often state that a symbol representing 10 to the power x may not precede any symbol larger than 10to the power x+1. For example, C cannot be preceded by I or V, only by X (or, of course, by a symbol representing a value equal to or larger than C). Thus, one should represent the number "ninety-nine" as XCIX, not as the "shortcut" IC. However, these rules are not universally followed.

lemme try
1000+CD=500-100+XC=100-10 +1+1=1492
1000+ CM= 1000-100+XC=100-10+5=1995
CM=1000-100 + XC 100-10+ IX 10-1 =999
