One of the factors that influence the weakness of problem solving skills is the learning style. The purpose of this study was to analyze students' mathematical problem solving abilities based on learning styles. The type of this research is descriptive quantitative, with the research subject being students of class VIII MTsN totaling 38 students.

Questionnaires are used to classify student learning styles, while problem solving ability tests are used to analyze students' problem solving abilities. The results of the study concluded that mathematical problem solving abilities of students who had a visual learning style were higher than the mathematical problem solving abilities of students who had audiotorial and kinesthetic learning styles.
