Development and Influence of Babylonian and Egyptian Numerals
The progression from simple tally marks to sophisticated numeral systems marks a significant leap in human intellectual history. Among the earliest and most influential of these systems were those developed by the Babylonians and Egyptians. These civilizations not only advanced the practice of mathematics but also laid the foundations for future scientific and mathematical discoveries.

Babylonian Numerals = A Sexagesimal System
The Babylonians, flourishing in Mesopotamia from around 2000 BC, developed one of the first positional numeral systems, using a base-60 (sexagesimal) system. This system, surprisingly advanced for its time, allowed them to perform complex calculations and astronomical observations with remarkable precision.
- Key Features: The Babylonian numeral system’s base-60 is evident in the modern-day division of hours into 60 minutes and circles into 360 degrees. Their cuneiform script made it possible to represent large numbers and fractions in a compact form, facilitating advancements in trade, astronomy, and architecture.
- Historical Context: Babylonian mathematics was heavily influenced by their practical needs for land measurement, construction, and astrology. Tablets such as the Plimpton 322 demonstrate their sophisticated understanding of Pythagorean triples and trigonometry centuries before Pythagoras (Robson, 2001).
Egyptian Numerals = Hieroglyphs and Hieratic Script
Parallel to the Babylonians, the ancient Egyptians developed their numeral system around 3000 BC, characterized by hieroglyphic symbols representing units, tens, hundreds, and so forth, up to millions. This system enabled them to build the pyramids, manage agricultural resources, and maintain a complex economy.
- Key Features: Egyptian numerals used a decimal base but were non-positional, meaning the same symbol could be repeated up to nine times to represent numbers. They also developed a simplified script, known as hieratic, for everyday calculations and administrative tasks.
- Scientific and Cultural Impact: The practicality of Egyptian numerals in recording vast quantities of goods and organizing labor for monumental projects reveals a society highly skilled in administration, planning, and engineering. The Rhind Mathematical Papyrus, dating back to around 1650 BC, illustrates the use of arithmetic, geometry, and fractions in solving practical problems (Peet, 1923).
Comparative Analysis
While both systems were revolutionary, their differences highlight diverse approaches to numeration and calculation. The Babylonians’ adoption of a positional system laid the groundwork for modern arithmetic and algebra, while the Egyptians’ emphasis on geometry and practical applications influenced Greek and Hellenistic mathematics.
Conclusion
The numeral systems of the Babylonians and Egyptians represent monumental achievements in the history of mathematics. Their development not only facilitated the administration of empires and the construction of architectural wonders but also pushed the boundaries of mathematical knowledge, laying foundational principles that continue to influence us today.
