A 30-Times Table

Below is an example of an Old Babylonian cuneiform tablet showing a standard multiplication table with principal number 30. The tablet is UM 29-15-503, from the University of Pennsylvania. The tablet is an example of a type that is common for compound tables, but less common for single multiplication tables.  It begins with the line '1 30'  and then continues ' 2  1', '3  1,30' and so on through the table.  The multiplication table takes up both sides of the tablet, and ends with '50  25'.  See the page on  Old Babylonian multiplication tables for more details.

This tablet was originally published by Neugebauer and Sachs in Mathematical Cuneiform Texts.

I thank Professor E. Leichty for permission to use the images of the tablets.
