At the end of this lesson, students should be able to subtract by borrowing or trading.

From this example what we do is called borrowing. We cannot subtract or take away **8** from **3** **=> 3 – 8**, so we borrow a 10 from the tens column. We then add this ten to the **3** units giving us **13**.

We then go ahead and subtract **8** from **13 => 13 – 8 = 5**
