How to use the Numerals
There are 4 basic rules for reading and writing Roman Numerals.
1. A Roman Numeral can only be repeated 3 times in a number.
For example: XXX = 30 or CC = 200
2. If one or more letters are placed after another letter of greater value then you add that amount.
For example: VI = 6 (5+1=6)
3. If one letter is placed before a letter with greater value, subtract that amount.
For example: IV = 4 (5-1=4)
4. If there is a line above a letter it increases the number by 1,000
For example: XV = 15

The Roman Empire
In Rome, houses had water suppled with lead pipes. The pipes were taxed depending on size so people could not take baths in their homes. People went to local baths and they were very useful. People could relax there and be clean. They also socialized to keep up with the recent news. Taking a bath was not a simple chore. They had to take a cold, warm, and hot bath. They was also an exercise area which included a swimming pool and gym. Building a bath required engineering skills as in heating up the water. The engineers used a furnace and the hypocaust system carried the heat. The water was constantly supplied. 640 kilometers of aqueducts were used. The complex bath was built by the emperor Diocletian. The baths sometimes contained mosaics and massive marble columns to have a purpose. The larger baths contained statues of gods and professionals. The staff massaged visitors and rubbed scented olive oil into their skin. The Roman baths were cheap. The saunas used to get rid of dirt. Some people enjoyed others were annoyed because of the noise. Today we have clean hot and cold running water to drink, brush teeth, wash hands and to bathe in.
These are roman numerals in script form.
One of the buildings in the Roman Empire is the Colosseum.
