By 130 AD, Ptolemy, influenced by Hipparchus and the Babylonians, was using a symbol for zero (a small circle with a long overbar) in his work on mathematical astronomy called the Syntaxis Mathematica, also known as the Almagest.

Slang words for zero include zip, zilch, nada, and scratch. By 1770 BC, the Egyptians had a symbol for zero in accounting texts.

The symbol nfr, meaning beautiful, was also used to indicate the base level in drawings of tombs and pyramids and distances were measured relative to the base line as being above or below this line.

By the middle of the 2nd millennium BC, the Babylonian mathematics had a sophisticated sexagesimal positional numeral system.

The lack of a positional value (or zero) was indicated by a space between sexagesimal numerals.
