In this paper we experience Foucaultian theorizations to analyze empirical material from a research about configurations of gender relations in mathematical practices of male and female collectors of recyclable materials, aged between 18 and 76, participants in an Association of Collectors, attendants of an Adult and Young Education Project (Educação de Pessoas Jovens e Adultas - EJA). By operating with a notion of discourse, we interpellate the Cartesian reason and the subject of reason, in order to show how relations of gender and mathematics are produced, entangled in discursive tensions, and are implicated in the constitution of subjectivities of those men and those women, male collectors and female collectors, male adult students and female adult students, and how they are also implicated in the naturalization of gender inequalities.
