Riese was one of the most influential German arithmeticians, widely credited with promoting the move from the table abacus to the pen. “The name Riese soon became so closely associated with arithmetic that until recently the German phrase nach Adam Riese would imply that a person had considerable ability in this area” (Tomash & Williams).
