The skill that students are expected to develop is mathematical literacy. But in reality, Indonesia still has a low level of mathematical literacy. One of the causes is learning obstacles. Therefore, this study aims to analyze learning obstacles in terms of mathematical literacy skills of quantity content. This research is qualitative research using didactic situation analysis. The subjects of this study were 28 students of class VII of SMPN 3 Sungguminasa. Data collection used mathematical literacy tests on quantity content, interview, observation, and documentation. The results showed that 1) Students experience ontogeny obstacles, where students do not have confidence in answering questions; 2) Students experience epistemological obstacles, namely students hesitate to answer story questions, students have difficulty in determining the right calculation operation, and students who know the calculation operation used in solving problems have difficulty regarding calculation operations; 3) Students experience didactic obstacles, where learning is only one-way and lack of reinforcement regarding prerequisite material.
