This free app is a math calculator, which is able to calculate the determinant of a matrix. The determinants of following matrices are available: - 2x2 matrices - 3x3 matrices - 4x4 matrices - 5x5 matrices - nxn matrices (with more than 5 rows and columns) Best math tool for school and college! If you are a student, it will helps you to learn! Note: In linear algebra, the determinant is a value associated with a square matrix. The determinant provides important information when the matrix is that of the coefficients of a system of linear equations, or when it corresponds to a linear transformation of a vector space.
