Determinant is a number associated with a type of matrix known as square, where
the number of rows and columns is equal.

A matrix is an ordered set of elements arranged in rows and columns, where "m" and "n" represent respectively rows and
columns.

The matrices and determinants are found not only in mathematics, but also practical applications in engineering,
computer science, finance etc .
