What to Focus On

  • |A| is read as determinant of A, not modulus of A.
  • Only square matrices have determinants.
  • A determinant of order 1 is the single element itself.

  • Order 1 determinant equals the single element.
  • Order 2 determinant uses the diagonal-product difference.
  • Order 3 determinant can be expanded along any row or column.

  • Scalar multiplication changes the determinant by the n-th power of the scalar.
  • Determinant of a product equals product of determinants.
  • Invertibility and non-singularity are equivalent.

Common Mistakes to Avoid

A determinant can be found for any matrix, including rectangular matrices.

|A| means the modulus of A.

For a 2x2 determinant, the answer is a11a22 + a12a21.

Memory Tips
