Calculating the determinant of a 3x3 matrix involves a method termed "expansion by minors". This process includes removing a row and column, determining the determinant of the 2x2 sub-matrices, multiplying these by the appropriate matrix elements while switching signs alternately, and ultimately, adding the outcomes.
