Plimpton 322 is a Babylonian clay tablet believed to have been created around 1,800 BCE. Approximately 5 inches (13 cm) wide and 3.5 inches (9 cm) tall, the tablet’s surface is marked by four columns of cuneiform numbers. Many mathematicians believe that the ancient spreadsheet—possibly used by a teacher to assign math problems to a student—demonstrates an understanding of Pythagorean mathematics that predates Pythagoras by more than 1,200 years. What do the numbers in each column represent? Discuss
