Order of Matrices Worksheets
We can identify the order of a matrix by the number of rows and columns. If there are m rows and n columns in a matrix, then the order is m x n. Matrices called by special names based on its order. If m = n, then the matrix called as square matrix. If m = 1, then it is row matrix, if n = 1, then it is column matrix.

A matrix is given. Identify the element of a matrix from the position of row and column. If the entry is a_{12}, identify the element from row 1 and column 2
Watch out the number of rows and columns.
Find the order of the resultant matrices after addition or subtraction. (No calculation; Just order)
Check the possibility for multiplication, then find the order of a resultant matrix.
Represent the equations in augmented matrix form. Coefficients of variables go left and the constant will go right.
Order of a Null or Unit Matrix
No matter what the entries are.
If the order of A is m x n, order of B is n x p, then the order of AB is m x p.
