    trying to take determinant of matrix using Maple

    In Maple I'm trying to take the determinant of a matrix and nothing happens
    Code:
    > A := matrix([[lambda+1, -2, -3], [-2, lambda+1, -2], [-2, -2, lambda+1]]);
    
    > detA := det(A);
                                 det(A)
    
    > B := matrix([[2, 1], [-4, 10]]);
    print(`output redirected...`); # input placeholder
    
    > det(B);
                                 det(B)
    
    > ans := det(B);
                                 det(B)

                                 det(B)
    First you need to load the linear algebra package

    with(LinearAlgebra):

    The Function Is Determinant(A) not det(A).

    Your matrix setup is correct.
