Question
draw an array to show 4x11=44

Answer
Hi Eva,

For 4 x 11, we let:

4 -> number of rows
11 -> number of '*' in each row

Here's how you draw the array step-by-step:

Since there are 11 '*' in each row, the row will looks like this:

* * * * * * * * * * *

Now, since there are 4 rows, just draw the row 4 times. This is how it looks like:

* * * * * * * * * * *
* * * * * * * * * * *
* * * * * * * * * * *
* * * * * * * * * * *

From the array above, the total number of '*' is 44.

That's all..

Best Regards,
