l When we move from left to right on a number line, the numbers become bigger.
l Numbers to the left of a given number are smaller than the number.
l Numbers to the right of a given number are bigger than the number.
Now, look at the following number line.
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
