Final Answer:
Here are the completed subtraction problems:
| 10 - 6 = 4 | 12 - 4 = 8 |
| 14 - 4 = 10 | 14 - 6 = 8 |
| 17 - 3 = 14 | 17 - 2 = 15 |
| 18 - 1 = 17 | 16 - 7 = 9 |
| 19 - 4 = 15 | 15 - 3 = 12 |
| 12 - 2 = 10 | 13 - 2 = 11 |
| 11 - 5 = 6 | 16 - 12 = 4 |

Boxed Final Answer:
\[
\boxed{
\begin{array}{cc}
10 - 6 = 4 & 12 - 4 = 8 \\
14 - 4 = 10 & 14 - 6 = 8 \\
17 - 3 = 14 & 17 - 2 = 15 \\
18 - 1 = 17 & 16 - 7 = 9 \\
19 - 4 = 15 & 15 - 3 = 12 \\
12 - 2 = 10 & 13 - 2 = 11 \\
11 - 5 = 6 & 16 - 12 = 4 \\
19 - 9 = 10 & 14 - 11 = 3 \\
\end{array}
}
