Fun with Roman Numerals

With many illustrations and examples, this book clearly explains how to use Roman numerals. It teaches readers when to add numerals together, as in the number VII, and when to subtract one from another, as in IX. This is contrasted with the way Arabic numerals work. The design helps reinforce the lessons; for example, each Roman numeral consistently appears in its own color. Fun with Roman Numerals also depicts many instances-from watch faces to the Super Bowl-where Roman numerals are used in everyday life. Conversion chart of Arabic and Roman numbers.
