Add to ORKGAbstract. Taking the 'operational/structural' perspective, as introduced by Sfard, this paper analyses the passage from computing with numbers and computing with letters. The discussion is based on a case study, taken from long term research project, still in progress. A key aspect, characterizing the transition from the two types of computation, will be highlighted: the change of role of operation properties
