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.
