How to read this

Add from the left, but subtract when a smaller letter comes before a larger one.
There are only seven letters: M=1000, D=500, C=100, L=50, X=10, V=5, I=1.
The same letter repeats at most three times — the fourth becomes a subtractive pair.
There is no zero, and the largest place value is always written first.
