Babylonian Number System

The Babylonian Number System has been around for over 4000 years.

This system was base 60 and used only two symbols: vertical wedge to represent one and a corner wedge to represent ten.

Cuneiform numbers were written using a combination of the two wedges.

There was no symbol for zero, but they did use the concept of zero by leaving a blank space.

Egyptian Number System

The Egyptian Number System was a decimal base system.

The Egyptians used a written numeration that was later changed into hieroglyphic symbols.

There was a special symbol for each power of ten.

The Egyptians did not have an understanding of zero.

Greek Number System

The Greek Number System is all based upon their alphabet.

The Greek alphabet contained 27 different symbols and is a combination of created symbols and borrow symbols.

The 27 symbols were combined together to represent any number up to 1000 and they used a comma after the first row of symbols to create numbers up to 10,000.

The Greek's did not have a concept of zero.

Mayan Number System

The Mayans use a vigesimal system that had a base of 20.

A dot was the symbol that represented numbers one through four and a dash represented five.

Their numbers were written vertically instead of horizontally.

The first five five place values were based on multiples of 20.

The Mayans did have a concept of zero and even created a symbol.

Combination of the vertical and corner wedges

The Babylonian Number System was founded on the clay mathematical tablet called Plimpton 322

Egyptian Hieroglyphic Symbols

The Egyptian Number System has been discovered on this piece of math history called the Rhind papyrus

This is a tablet of the 27 Greek alphabet symbols. They combined these symbols to create numbers up to 10,000.

A Mayan long count calender that provides evidence of the Mayan Number System.

Tablet of the different combinations of the two symbols that the Mayans used and their symbol for zero.

Hindu-Arabic Number System

The Hindu-Arabic Number System is the number system that we use and is widely used across the world.

This system uses ten different digits that can be combined together to represent all numbers.

This system is a base ten decimal system.
