Numerical mathematics often brings together expertise in numerical analysis and information technology. As computational scientists, we are adept at computing, or at data processing and management. Because we constantly go back and forth between discrete and continuous theories, because we develop and analyse algorithms used by other disciplines, we are often at the interface between theory and applications. Our mathematics is carried out in co-construction (see what is co-construction?).
Furthermore, we cannot simply define ourselves as computational scientists since we can also be analysts, information technologists, or even physicists, biologists or economists; we are often interdisciplinary. Indeed, we are like a bridge between the abstract and the concrete.
