Mathematical literacy and mathematical numeracy are basic skills that are crucial for educational progress and individual development. However, students' mathematical literacy and numeracy skills in Indonesia must still meet the expected standards. Therefore, this research aims to analyze students' errors in solving mathematical literacy and mathematical numeracy questions. This research uses qualitative research with a descriptive approach. In this study, six subjects were selected using a purposive sampling technique, with two subjects representing high, medium, and low ability categories. Subject selection criteria are based on the results of essay tests in the algebra domain. Mathematical literacy and mathematical numeracy abilities were analyzed through student error analysis using the Newman error indicator, which includes five procedures: (1) reading, (2) comprehension, (3) transformation, (4) process skills, and (5) encoding. The results showed that students' error rates varied depending on the level of mathematical literacy and numeracy skills. Subjects in the high ability category generally need to improve comprehension, processing skills, and answer writing stages. Subjects in the medium ability category typically make mistakes in the reading, comprehension, processing skills, and answer writing stages. Then, subjects in the low category tend to make mistakes at all stages of analysis. The recommendations from this study are expected to provide valuable insights for educators in designing more effective learning strategies to overcome these errors.

Problem-solving abilities are essential for students to face developments in the 21st century. This research examines students' problem-solving abilities in solving ethnomathematics-based problems in terms of Keirsey's personality type. This research uses a qualitative approach with a case study method. The research instrument is a questionnaire to measure Keirsey's personality type (artisan, guardian, idealist, and rational), an ethnomathematics-based problem-solving test instrument with the Polya problem-solving stages. Research subjects were chosen based on specific considerations: students with artisan, guardian, idealist, and rational personality types. Data collection was carried out using questionnaires, tests, and interviews. Based on the results of the analysis, it was found that each student with a different personality type had different problem-solving abilities. Students with a rational personality type can fulfill all stages of Polya problem-solving in each problem. Students with the guardian personality type skip checking back on a problem. Students with an artisan personality type lack planning. Meanwhile, students with an idealistic personality type cannot fulfill the problem-solving stages in all problems. These findings emphasize differences in problem-solving abilities for each personality type, so they can be used as a reference for designing learning based on personality type.
