According to Algebra, a determinant basically is a task depending on n that associates a scalar, det(A), to every n×n square matrix A. The basic geometric meaning of a determinant is as the scale factor for volume when A is thought of as a linear transformation.
Determinants are generally essential in both calculi, where they enter the substitution rule for many variables and also in multi linear algebra. For a set positive integer n, there is an exclusive determinant meaning for the n×n matrix over any commutative ring R.
Predominantly this meaning is there when R is the field of real or compound numbers. A determinant of A is even at times indicated by |A|, but this notion is ambiguous. It is even applied for particular matrix norms and even for absolute value.
