The Number Which Is Always Positive, Even if It's Negative

This study examines how students solve problems that involve the concept of absolute value. One hundred seventeen students participated in the first (written) part of the study, 24 students participated in the second part (interview). Particular attention was paid to the actual process of problem solving and to the students' ability to establish connections between different mathematical techniques and representations. The analysis presented here facilitates the theoretical description of the way in which new concepts are learned, and makes it possible to recognize important problems that working teachers face.
