  1. Interchange any row (or column) of Tand show that the sign of the determinant changes but not the numeric value.

  1. Multiply any row (or column) of T, with 3 and investigate whether the value of the determinant changes 3 – fold.

  1. Investigate: If each element of a row (or column) is added to (or subtracted from) the corresponding element of another row (or column), the value of the determinant remains the same.

  1. Investigate: If one row (or column) is a multiple of another row (or column) then the determinant is zero.
