In this section, we will learn about what an invertible matrix is. An invertible matrix is a square matrix that has an inverse. We say that a square matrix is invertible <a href='[[glossary.html|{"keyword":"if and only if"}]]'>if and only if</a> the determinant is not equal to zero. In other words, a 2 x 2 matrix is only invertible if the determinant of the matrix is not 0. If the determinant is 0, then the matrix is not invertible and has no inverse.
