Just as we can add, subtract and multiply numbers, so can we do the same with Roman numerals. Let’s look at the following example:
III - II = ?
III is the same as 1 + 1 + 1 = 3
II is the same as 1 + 1 = 2
III - II then is the same as 3 - 2 = 1
“1” in Roman numerals is “I” so the complete answer is: III - II = I
Now let’s look at another example:
IX x IV = ?
IX is the same as 10 - 1 = 9
IV is the same as 5 - 1 = 4
IX x IV then is the same as 9 x 4 = 36
“36” in Roman numerals is XXXVI so the complete answer is: IX x IV = XXXVI
Some helpful hints to remember are:
5 = V
10 = X
50 = L
100 = C
500 = D
1000 = M
