WebSo , here is a trick -. Simply, rewrite the first two columns alongside the first three columns and then for going diagonally down, add and for climbing up , subtract. So,The determinant of the three columns on the left is the sum of the products along the down-right diagonals minus the sum of the products along the up-right diagonals. 2. WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A).
