    Determinant Evaluation

    I have the following determinant.

    Code:
    |1 2 3 4|
    |5 6 7 8|
    |2 6 7 8|
    |3 1 1 2|

    So is my evaluation correct?

    Code:
    1 x  |6 7 8| - 2 x |5 7 8| + 3 x |5 6 8| - 4 x |5 6 7|
         |6 7 8|       |2 7 8|       |2 6 8|       |2 6 7|
         |1 1 2|       |3 1 2|       |3 1 2|       |3 1 1|
