AB - <p>This paper presents the numerical analysis by evaluating an nxn matrix of Chio’s<br>condensation method in comparison to Dodgson’s condensation method. The computation for<br>both methods applies the reduction of (n-1)x(n-1) matrix and finds the determinant of 2x2<br>matrix. These techniques are different from the commonly practice - reducing an nxn matrix and<br>spreading cofactors of matrix - using Sarrus’s rule to compute the determinant of 3x3 matrix.<br>Different methods provide the same result, but each technique is more appropriate to specific<br>value of elements in varied matrices than any others. This paper will, therefore, demonstrate the<br>analysis for two means of calculations.</p>
