Edit: Confused on how Roman numerals work? Don't worry! @MailicedeNamedy has you covered. Here's an explanation from a post she made later on in this thread.

1,2,3
5= V
10 = X
50 = L
100 = C
500 = D
1000 = M
The numbers are counted.
We are now at CXLVII
which is C+(X-L)+V+I+I
If the letter is smaller than the next one, you subtract it. Especially in large numbers, it can be hard.
MCMXCIV stands for 1994
Remember the numbers from above:
1000 (M)-----------------1000
C-M (100-1000)---------+900
X-C (10-100)-------------+90
I-V (1-5)------------------+4
=1994
