This research aims to determine the influence of concept understanding ability (X1), communication ability (X2) and mathematical connection ability (X3) on problems solving ability (Y); the influence of concept understanding ability (X1) on communication ability (X2); the influence of concept understanding ability (X1) on mathematical connection ability (X3) and communication ability (X2) on connection ability (X3). This research is a survey research with quantitative approach. Population of the research is the second grade students of Public Junior High School 1 of Padang Jaya. The taking of samples use non-probability sampling method. Type of sampling is saturated samples. The taking of data uses Likert Scale and description as the test instruments. Method of data analysis uses Path Analysis with significance level 5%. Results of the research shows that (1) concept understanding ability (ρyx1X1 = 0,374), communication ability (ρyx2X2 = 0,181 and connection ability (ρyx3X3 = 0,201) influence on problems solving ability; (2) the influence of concept understanding ability (ρx2x1X1= 0,323) on communication ability; (3) concept understanding ability (ρx3x1X3 = 0,442) influences on connection ability and (4) communication ability (ρx3x2X3 = 0,470) influences connection ability.
