#### Worksheet Overview

The Romans used the following symbols to represent their counting numbers:

 I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1000

Certain rules apply.

A letter placed after another letter means that you add the second letter to the first letter. Examples include:

 VI = 5 + 1 = 6 VII = 5 + 1 + 1 = 7 VIII = 5 + 1 + 1 + 1 = 8 XI = 10 + 1 = 11 LX = 50 + 10 = 60 MC = 1000 + 100 = 1100

A letter placed before another letter means that you subtract the first letter from the second. Examples include:

 IV = 5 - 1 = 4 IX = 10 - 1 = 9 XL = 50 - 10 = 40 CM = 1000 - 100 = 900

Example

For what number does this Roman numeral stand?

MMCMXLIX

MM = 2000

CM = 1000 - 100 = 900

XL = 50 - 10 = 40

IX = 10 - 1 = 9

So MMCMXLIX = 2949

It may look complicated, but just take it one step at a time and you'll soon get the hang of it.
