Babylonian cuneiform numerals, also used in Assyria and Chaldea, were written in cuneiform, using a wedge-tipped reed stylus to print a mark on a soft clay tablet which would be exposed in the sun to harden to create a permanent record. The Babylonians, who were famous for their astronomical observations, as well as their calculations (aided by ...
Pictographs then began to appear on clay tablets around 4000 BCE, and after the later development of Sumerian cuneiform writing, a more sophisticated partial syllabic script evolved that by around 2500 BCE was capable of recording the vernacular, the everyday speech of the common people. [7] Sumerians used what is known as pictograms. [5]
