Abstract
Mathematics, as a subject that is well known and studied by elementary school to middle school students, aims to ensure that students can understand and master it well to experience its benefits in everyday life. One of the mathematical skills that students must have is literacy and numeracy skills. Students' mathematical literacy and numeracy abilities are important components of measuring students' cognitive abilities. However, based on the results of initial observations at SMA Negeri 3 Kuningan, in reality, students' mathematical literacy and numeracy skills are still low, as can be seen from their difficulties in understanding, using, and communicating mathematical numbers and symbols, including analyzing data from graphs, tables, and diagrams for retrieval. This research investigates how the method is implemented: problem-based learning (PBL), integrated with differentiated learning, can influence students' mathematical literacy, numeracy skills, and ability to solve mathematical problems. The research method uses an experimental approach. The research results were obtained from test results N-Gain, with scores of 0.56 (medium category) and an increase percentage of 56.05%. This increase can be seen significantly in students' mathematical literacy and numeracy indicators. Students show better abilities in understanding, interpreting, and analyzing problem-based questions related to mathematical concepts. Overall, there is an increase in students' mathematical literacy and numeracy skills
