A special value that is calculated by the elements of a square matrix is called as the determinant. It is calculated to find the number of solutions of a system. (i.e.,) If the determinant is equal to 0, system has one solution. If it is greater than 0, two solutions and if smaller than 0, it has no solutions. Find the determinant of the matrix by entering the elements separated by space.

4 5

Determinant = (1*5) - (2*4)

= 5 - 8

= -3
