The data obtained from the written test about the problem solving ability of mathematics as much as 5 questions. Based on the results of research conducted from the test 5 problem solving mathematical problems only 29% of students who master the problem of solving mathematical problems, means 71% of students do not master the problem of problem solving mathematics. The average value of students is 5.68 with highs of 13 and lows one of the maximum value of 20.
