Change the signs of the 2 and the 3 to get negative 2 and negative 3. Finally, you divide every element in this new matrix by the determinant calculated in the previous step.
Swap the 1 and the 4 to get 4 and 1. Assume you have a matrix labeled A, composed of four elements arranged in two rows and two columns.

For a 2x2 matrix, this process is streamlined into a specific formula that relies on the determinant, a single number calculated from the matrix elements. First, calculate the determinant: (1 times 4) minus (2 times 3), which equals negative 2.
