Show that the elimination method of computing the value of the determinant of an n × n matrix involves [n(n − 1)(2n − 1)]/6 additions and [(n − 1)(n2 + n + 3)]/3 multiplications and divisions. Hint: At the ith step of the reduction process, it takes n − i divisions to calculate the multiples of the ith row that are to be subtracted from the remaining rows below the pivot. We must then calculate new values for the (n − i)2 entries in rows i + 1 through n and columns i + 1 through n.
