👉 In mathematics, a determinant is a square matrix that contains all the entries of a given square matrix. It is an important tool in linear algebra and geometry, used to solve systems of linear equations and calculate determinants. A determinant can be thought of as a number that represents how many times a certain row or column appears in the product of two matrices. For example, if A is a 2x3 matrix and B is a 3x4 matrix, then det(A) = (ad
