Abstract

- Mathematically speaking, a difference is the result of a subtraction. However, when the number domain is extended from natural numbers to integers, the separation of the magnitude of a number from its value creates “different differ-ences,” where the connection to subtraction is no longer straightforward. Based on video-recorded lessons and individual student interviews with 21 students in a Swedish year 8 class, a conceptual metaphor analysis of the discourse shows how ambiguous the term difference can be and how an implicit use of metaphors can create confusion in relation to addition and subtraction with integers.
