The Romans used capital letters to write their numbers. Roman numbers are called numerals.
If you put a letter after a larger one it means you add it.
Here is an example:
LII = 52
This means 50 (L) + 2 (II) = 52
50 + 2 = 52
If you put a letter before a larger one it means you take it away.
Here is an example:
XC = 90
This means you take 10 (X) away from 100 (C)
100 - 10 = 90
Now that you have read some examples of Roman numerals, let's start the activities.
