Roman numerals are from the systematic mathematics of the Roman Empire. The Roman Empire had inspirational, industrious and intellectual beginnings. Emperors Aristotle, Euclid, Archimedes and more philosophers helped to build Rome into an ancient power, developing sophisticated intellectual and mathematical skills to build the coliseum, pantheon and more important buildings
They have also developed their own mathematics, called Roman Numerals. However, their number system was flawed, it had no zero (0), and no single method for counting above several thousand units. The fall of the Roman Empire by 300 A.D. saw the introduction and adoption of Arabic Numerals. This system consistently worked because of the invention of zero (nothing)
Roman numerals are used today most frequently as list numbers and art and antiques in museums and shops. Roman numerals are even accessible on nearly all computer word processing packages (word, PDF) and allows upper and lowercase Roman Numerals to use as item indicators. Roman Numerals have been around and are still around to assist with our every day lives.
