Arranging the given numbers in ascending order using a number line:
First, we look for the smallest number, which is -13. We place it on the leftmost side of the number line.
Next, we place -3 to the right of -13.
Then, we place 23 to the right of -3.
After that, we place 30 to the right of 23.
Finally, we place 230 to the right of 30.
So, the numbers arranged in ascending order are:
-13, -3, 23, 30, 230
