Matrices

Step 1: Understanding column matrix

A column matrix is a matrix where the number of rows is greater than the number of columns, and it consists of a single column. The general form is:

Step 2: Conclusion.

Thus, a column matrix is a matrix that has only one column, with multiple rows.

Step 1: Matrix addition.

To find , we add the corresponding elements of matrices and :

Step 2: Conclusion.

Thus, the sum is:

Step 1: Matrix multiplication.

To find , we multiply the two matrices and . Matrix multiplication is done by taking the dot product of rows of with the columns of . The element in the first row and first column of is: The element in the first row and second column of is: The element in the second row and first column of is: The element in the second row and second column of is:

Step 2: Conclusion.

Thus, the product is:
