This gives us [[6, -7], [-2, 4]]. The defining property of an inverse matrix A⁻¹ is that when it multiplies the original matrix A , the result is the identity matrix.

Next, swap the elements in the top-left and bottom-right corners. Given a matrix A = [[a, b], [c, d]] , the inverse A⁻¹ is calculated as (1 / (ad - bc)) * [[d, -b], [-c, a]].
The inverse of a matrix essentially acts like the reciprocal of a number; just as dividing by a number is the same as multiplying by its reciprocal, multiplying a matrix by its inverse yields the identity matrix. For our example B × B⁻¹ , the multiplication yields [[(2.

Since the determinant is 10, the inverse exists. The term (ad - bc) is the determinant of the matrix.
