Important Terms About Matrices:

  • All main diagonal elements of a skew-symmetric matrix are zero.
  • Every square matrix can be uniquely expressed as the sum of a symmetric and a skew symmetric matrix.
  • All positive integral power of a symmetric are symmetric.
  • All odd positive integral power of a skew symmetric matrix are skew symmetric.



Properties of Matrix addition:
  • Commutativity: If A and B are two matrices of same order, then A + B = B + A.
  • Associativity: If A, B, C are three matrices of same order, then (A + B) + C = A + (B + C).
  • Existence of Identity: The null matrix is the identity element for matrix addition. A + O = O + A = A.
  • Existence of inverse: For every matrix A = [aij, there exists a matrix – A= [-aij] such that A + (-A) = O = (-A) + A.
  • Cancellation laws: If A, B, C are three matrices of the same order, then A + B = A + C implies that B = C and B + A = C + A implies that B = C.
