This project is devoted to fundamental concepts of scientific computing at the crossover from school to university. The goal of this project is to develop a book titled 'Introduction to computer-oriented mathematics' together with an associated web version. The main issues concern - striking examples bridging the gap between accessibility for first semester students of and the flavour of real-world applications - web-based, illustrative material, some of these interactive. A companion project not funded by Matheon will provide a corresponding e-learning unit.
