This study aims to determine the impact of using Microsoft Mathematics application on students' concept understanding ability in multiplying two matrices and determining matrix determinant. This type of research is qualitative research with a case study approach. This research was conducted in one of the state high schools in Kolaka in class XI IPA. The number of subjects in this study were 3 students. Data collection techniques in this study were using tests and interviews to determine students' understanding of the concept of multiplication of two matrices and the concept of determinant. The results of this study are students who previously did not understand well related to the concept of multiplying two matrices, but after using the microsof mathematics application understand well related to the concept of multiplying two matrices and when the two matrices can be multiplied. In addition, students also understand well the procedures and concepts in determining the determinant of the matrix. Therefore, Microsoft Mathematics application is highly recommended to be used by teachers in introducing the concept of multiplication of two matrices and the concept in determining the determinant of the matrix.
