Answer 1

The Babylonian Number System

The Babylonians lived in Mesopotamia, which is between the Tigris and Euphrates rivers. They began a numbering system about 5,000 years ago. It is one of the oldest numbering systems. The first mathematics can be traced to the ancient country of Babylon, during the third millennium B.C. Tables were the Babylonians most outstanding accomplishment which helped them in calculating problems.

One of the Babylonian tablets, Plimpton 322, which is dated from between 1900 and 1600 BC, contains tables of Pythagorean triples for the equation a2 + b2 = c2. It is currently in a British museum.

Nabu - rimanni and Kidinu are two of the only known mathematicians from Babylonia. However, not much is known about them. Historians believe Nabu - rimanni lived around 490 BC and Kidinu lived around 480 BC.

The Babylonian number system began with tally marks just as most of the ancient math systems did. The Babylonians developed a form of writing based on cuneiform. Cuneiform means "wedge shape" in Latin. They wrote these symbols on wet clay tablets which were baked in the hot sun. Many thousands of these tablets are still around today. The Babylonians used a stylist to imprint the symbols on the clay since curved lines could not be drawn.

The Babylonians had a very advanced number system even for today's standards. It was a base 60 system (sexigesimal) rather than a base ten (decimal). Base ten is what we use today.

The Babylonians divided the day into twenty-four hours, each hour into sixty minutes, and each minute to sixty seconds. This form of counting has survived for four thousand years.

Any number less than 10 had a wedge that pointed down.

Example: 4

The number 10 was symbolized by a wedge pointing to the left.

Example: 20

Numbers less than 60 were made by combining the symbols of 1and 10.

Example: 47

As with our numbering system, the Babylonian numbering system utilized units, ie tens, hundreds, thousands.

Example: 64

However, they did not have a symbol for zero, but they did use the idea of zero. When they wanted to express zero, they just left a blank space in the number they were writing.

When they wrote "60", they would put a single wedge mark in the second place of the numeral.


When they wrote "120", they would put two wedge marks in the second place.


Following are some examples of larger numbers.

Example: 79883

(22*6022)+(11*60)+23


Example: 5220062

(24*603) + (10*602) + (1*60) + 2
