In the last post, I discussed about calculating determinants of 1 x 1 and 2 x 2 matrices. This post will teach you to calculate determinants of 3 x 3 matrices. The procedure is to choose any row or column from the matrix. It is better to choose a row or column which is having
maximum number of zeros if there are any. The rest of the procedure is present in the file present below. Go through it for better clarity and detailed explanation.
