Subtraction by Counting Backward

We can also subtract the numbers on the number strip.

First, mark the larger number on the strip, then move

backward as many steps as the smaller number (the number

is to be subtracted) on the strip to reach at the answer.

Look at the following.

8 – 4 = 4 1 2 3 4 5 6 7 8 9 10
