The Attic-Greek Number System

Last week in class, we learned about 4 different number systems. The one that I personally found the easiest one to understand was the Attic-Greek Number System(Also known as the Roman System).

Here is a picture of the Attic-Greek System to help visualize what it looks like:

The Attic-Greek system is Non-Postional and does not have a zero involved in it. Non-positional means that no matter how you arrange the symbols when you write them down, the position of the numbers does not matter. Zeroes are not involved because that is just the way the Greek People decided to make it. This system is also a base ten system which means that the grouping of the numbers is done by 10's.

This site helps to show how each number is represented, how to find out what different numbers are, and it shows good graphics in how to write the symbols down.
