Question

Create a matrix with 3 rows and 4 columns. Every element in the first row should be 0, every element in the second row should be 1, and every element in the third row should be 2.

Answer 1

`\left[\begin{array}{cccc}0&0&0&0\\1&1&1&1\\2&2&2&2\end{array}\right]`

Explanation:

The matrix should have

- A row with four horizontal zeros

- A row with 4 horizontal ones

- A row with 4 horizontal twos

Thus, it should have the following form

`\left[\begin{array}{cccc}0&0&0&0\\1&1&1&1\\2&2&2&2\end{array}\right]`

Always remember that the columns are vertical (just think about normal columns) and the rown are horizontal.

I hope that works for you!
