If you have no clue how roman numerals work, here is a quick overview. Let’s start with some basic numbers:

i = 1

ii = 2

iii = 3

v = 5

x = 10

l = 50

c = 100

d = 500

m = 1000

You’ll see these in uppercase or lowercase form.

By combining the numbers you can make other numbers. One way to do so is by placing a smaller number in front of a larger number. The effect is similar to subtraction:

iv = 4 (think 5-1)

xl = 40 (think 50-10)

On the other hand, if you place the smaller number after the larger number then you’re adding the two:

vii = 7 (think 5+2)

lxxxii = 82 (think 50+30+2)

You can also combine these two methods:

xcii = 92 (100-10+2)

There are a few more rules for adding and subtracting, but hopefully this clarifies the basic principles.
