WebDeterminants 4.1 Definition Using Expansion by Minors Every square matrix A has a number associated to it and called its determinant,denotedbydet(A). One of the most important properties of a determinant is that it gives us a criterion to decide whether the matrix is invertible: A matrix A is invertible i↵ det(A) 6=0 .
