The determinant is calculated as 1*(1*1 - 0*3) - 2*(0*1 - 0*2) + 1*(0*3 - 1*2) = 1 - 0 - 2 = -1.

The determinant is (2*3) - (1*1) = 6 - 1 = 5.

The determinant is (4*1) - (2*3) = 4 - 6 = -2.

The determinant is 1 because it is an upper triangular matrix.

The determinant is 0 because the rows are linearly dependent.

The determinant is calculated using the rule of Sarrus or cofactor expansion, which results in 0.

The determinant is calculated as 0*(0*0 - 3*3) - 1*(1*0 - 3*2) + 2*(1*3 - 0*2) = 0 + 6 + 6 = 12.

The determinant is calculated as (1*4) - (2*3) = 4 - 6 = -2.

The determinant is (2*7) - (3*5) = 14 - 15 = -1.

The determinant is (3*4) - (2*1) = 12 - 2 = 10.
