The oldest known multiplication tables were used by the Babylonians about 4000 years ago. [2] However, they used a base of 60. [2] The oldest known tables using a base of 10 are the Chinese decimal multiplication table on bamboo strips dating to about 305 BC, during China's Warring States period. [2] "Table of Pythagoras" on Napier's bones [3]
This tablet, believed to have been written around 1800 BC, has a table of four columns and 15 rows of numbers in the cuneiform script of the period. This table lists two of the three numbers in what are now called Pythagorean triples , i.e., integers a , b , and c satisfying a 2 + b 2 = c 2 .

Numbers were in the Greek world of Pythagoras' days natural numbers – that is positive integers (there was no zero). But unlike their Greek contemporaries, the ...
It is now widely accepted as a result of Jens Høyrup's extensive analysis of the vocabulary of Old Babylonian mathematics, that underlying the procedures in texts such as IM 67118 was a set of standard cut-and-paste geometric operations, not a symbolic algebra. [8] [9] Possible geometric basis for a solution of IM 67118.
