In a paper in this week's Science, Maria del Carmen Jorge y Jorge and Barbara Williams analyzed the records of the Aztecs to try to understand how they might have calculated areas of quadrilaterals without knowing the angles. They show that the recorded areas were produced by an indigenous calculation system that relied on a basic unit of distance measurements. I spoke with del Carmen Jorge y Jorge from Mexico City and began by asking her to describe the five algorithms the Aztecs used
