It might help if you break the numbers down into thousands, hundreds, tens and units.

Here are some examples to help you follow the rules:

What number is "XII"?

Using rule number one, and breaking the number down into tens and units:

X= ten

II= two

The two comes after the ten, and so we add two to ten, and get the number 12.

What about "IX"?

This time, we use rule number two:

X=ten

I= one.

The one comes before the ten, and so we subtract one from ten, and get the number 9.
