WebIf it’s so, then you can proceed and apply general formula for calculating determinants which goes as follows: \Delta =\sum_ {i,j=1}^ {n} (-1)^ {i+j}a_ {ij}M_ {ij} Δ = i,j=1∑n (−1)i+jaijM ij Here $n$ is the size of your square matrix. Next you pick some row or column and perform expansion, getting thus a bunch of smaller determinants to calculate.
