Remember the related subtraction facts for doubles facts.
| 1 + 1 = 2 2 – 1 = 1 |
6 + 6 = 12 12 – 6 = 6 |
| 2 + 2 = 4 4 – 2 = 2 |
7 + 7 = 14 14 – 7 = 7 |
| 3 + 3 = 6 6 – 3 = 3 |
8 + 8 = 16 16 – 8 = 8 |
| 4 + 4 = 8 8 – 4 = 4 |
9 + 9 = 18 18 – 9 = 9 |
| 5 + 5 = 10 10 – 5 = 5 |
10 + 10 = 20 20 – 10 = 10 |
Let's find difference of 18 and 9.
