# How to Convert Roman Numerals to Arabic Numbers

Different from Arabic numbers , there are 7 Roman numerals: I, V, X, L, C, D and M, where V is equal to 5 and M is equal to 1000.

The basic rule is when the larger number is in front, then add, when the smaller number is in front, then minus. For example:

• VI: where V is 5 and I is 1, V is larger and in front, so add the 2 numbers together 5+1 = 6
• IL: where L is 50 and I is 1, I is smaller and in front, so minus the 2 numbers together 50-1 = 49
• where the letters are the same, add together: III = 1 + 1 + 1 = 3
