The instrument consisted of four questions designed and interview guidelines. Data were analyzed descriptively based on written test results and interviews to confirm students’ work. The results of this study showed that 65.3 percent of students made mistakes in solving mathematical literacy level 3 and 73.68 percent of students made mistakes in solving mathematical literacy level 4. Students error that arise in solving these mathematical literacy problems are understanding the problem and choosing the information to get a solution. Based on the results, researcher suggest that the preparation of sentences in the mathematical literacy problem, it should be emphasized with the precise sentences, so that the purpose of the problem is well understood by students.
