2. 1. existence of non-zero matrices whose
product is the zero matrix.
2. Concept of elementary row and column
operations.
3. Proof of the uniqueness of inverse, if it
exists.

4.
5. A matrix having m rows and n columns is called a
matrix of order m × n or simply m × n
matrix (read as an m by n matrix).
26. The product of two matrices A and B is defined if the
number of columns of A is equal to the number of
rows of B. Let A = [aij] be an m × n matrix and B = [bjk]
be an n × p matrix. Then the product of the matrices A
and B is the matrix C of order m × p.
