Order of operations: A case of mathematical knowledge-in-use
Page: 1035
I describe reactions of secondary school mathematics teachers to the following assertion: “According to the established order of operations, division should be performed before multiplication”. I use the notions of local and nonlocal mathematical landscape (Wasserman, 2016) to analyze teachers’ responses to the convention of order of operations in general and the presented assertion in particular.
