context_page_description: Plimpton 322 is a Babylonian clay tablet, notable as containing an example of Babylonian mathematics. It has number 322 in the G.A. Plimpton Collection at Columbia University. This tablet, believed to have been written about 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 a² + b² = c². From a modern perspective, a method for constructing such triples is a significant early achievement, known long before the Greek and Indian mathematicians discovered solutions to this problem. At the same time, one should recall the tablet's author was a scribe, rather than a professional mathematician; it has been suggested that one of his goals may have been to produce examples for school problems.
  There has been significant scholarly debate on the nature and purpose of the tablet. Robson is a more detailed and technical discussion of the interpretation of the tablet's numbers, with an extensive bibliography.
