Mathematical Treasure: Fifteenth Century Division Practice

Author(s): 
Frank J. Swetz (The Pennsylvania State University)

“Dura cosa e la partita, or “Division is a difficult thing,” was a common sentiment among mathematical practitioners of the Middle Ages, particularly if they were computing on an abacus. Even when Hindu-Arabic (Indo-Arabic) numerals and their computing algorithms were introduced, the operation was considered difficult. Here, a fifteenth century Italian student practices his division techniques. A modern viewer should carefully examine and try to understand the processes being demonstrated.
