Step 1: Matrix
Then we need evaluate a matrix, it must be a square matrix of order n×n. it can be 2×2,3×3,4×4
For eg:
abcd2×2 is a square matrix of order 2×2
abcdefghi3×3is a square matrix of order 3×3
Step 2: Evaluating a matrix
A=abcd2×2we can evaluate the 2×2 matrix by multiplying the and then subtracting it
A=ad-bc
For 3×3matrix

Hide row and column along which we evaluating the matrix
Then the remaining element is efhithenA=ei-fhin this we evaluate the matrix along element a.
Similarly, if we evaluate the matrix along element b then A=dfgithenA=di-gf
Hence, in this way we can evaluate a square matrix .
