Enumeration systems

The current number system that is common throughout the world is called Hindu-Arabic. This system was developed in Indian and introduced to the Arabic world in the 10th century. It is a decimal (base 10) with place value and a zero.

Each row is the same number written in different systems. See if you can identify the missing numbers in the chart below. A few hints are located on the next page.
