This strategy is very similar to 'subtract tens then ones'. This time, take away the **ones** first. Then, take away the **tens**.

For example, let's look at 48 minus 28. First, take away 8 (the **ones**) from 48 to leave 40. Then, take away the 20 (the **tens**) from 40 to leave 20.

Let's find the answer to 57 minus 33 using this strategy. First, take away the **ones** from 57. Then, take away the **tens** from that.

Did you get 24 for your answer?
