Construct a `2xx3` matrix `A=[a_(i j)]` whose elements `a_(i j)` are given by: (i) `a_(i j)=ixxj` (ii) `a_(i j)=2i-j`

Explanation

To construct the `2x3` matrix `A=[a_(i j)]` with the given definitions of its elements, we will follow these steps:

### Step 1: Define the Matrix Dimensions
We need to construct a matrix `A` with 2 rows and 3 columns. Therefore, the dimensions of the matrix will be `2x3`.

### Step 2: Case 1 - Define Elements as `a_(i j) = i * j`
For the first case, we will use the formula `a_(i j) = i * j`. Here, `i` represents the row number and `j` represents the column number.
