This article reports the macro-organizational structure of research articles in mathematics, based on an analysis of 30 published pure and applied mathematics articles. Math RAs eschew the Introduction-Methods-Results-Discussion structure for an Introduction-Results model that enables researchers to present new knowledge as clearly and succinctly as possible. Notable omissions from the mathematics RA structure are Method and Discussion sections, which mathematicians do not need because of the well-established methodology used in the field and the relative absence of extended discussion required to (...) interpret research findings. We contextualize the macrostructure of RAs in mathematics within the discourse conventions and disciplinary assumptions about knowledge in the field to suggest the value of such a strategy to teachers and students of academic writing.
