Problem Description:

The task involves solving subtraction crossword puzzles. Each puzzle consists of a grid where numbers are subtracted step-by-step, and the results must be filled into the grid. The goal is to complete each puzzle by performing the subtraction operations correctly.

Solution Approach:

1. Understand the Structure: Each puzzle has a series of subtraction operations that need to be performed sequentially.
2. Perform Subtraction: Start with the given number at the top and subtract the subsequent numbers in the sequence.
3. Fill in the Grid: Write the intermediate and final results in the corresponding cells of the grid.
4. Check Consistency: Ensure that all rows and columns align correctly with the subtraction operations.

Detailed Solution for Each Puzzle:

#### Puzzle 1:
```
34 - 12 - 9 = ?
```
- Start with 34.
- Subtract 12: \( 34 - 12 = 22 \).
- Subtract 9: \( 22 - 9 = 13 \).

Grid Filling:
```
34 - 12 - 9 = 13
```

#### Puzzle 2:
```
26 - 10 - 9 = ?
10 - 4 - 4 = ?
9 - 2 - 3 = ?
```
- For the first row:
- Start with 26.
- Subtract 10: \( 26 - 10 = 16 \).
- Subtract 9: \( 16 - 9 = 7 \).
- For the second row:
- Start with 10.
- Subtract 4: \( 10 - 4 = 6 \).
- Subtract 4: \( 6 - 4 = 2 \).
- For the third row:
- Start with 9.
- Subtract 2: \( 9 - 2 = 7 \).
- Subtract 3: \( 7 - 3 = 4 \).

Grid Filling:
```
26 - 10 - 9 = 7
10 - 4 - 4 = 2
9 - 2 - 3 = 4
```

#### Puzzle 3:
```
39 - 5 - 16 = ?
15 - 4 - 7 = ?
12 - 3 - 1 = ?
```
- For the first row:
- Start with 39.
- Subtract 5: \( 39 - 5 = 34 \).
- Subtract 16: \( 34 - 16 = 18 \).
- For the second row:
- Start with 15.
- Subtract 4: \( 15 - 4 = 11 \).
- Subtract 7: \( 11 - 7 = 4 \).
- For the third row:
- Start with 12.
- Subtract 3: \( 12 - 3 = 9 \).
- Subtract 1: \( 9 - 1 = 8 \).

Grid Filling:
```
39 - 5 - 16 = 18
15 - 4 - 7 = 4
12 - 3 - 1 = 8
```

#### Puzzle 4:
```
35 - 11 - 13 = ?
8 - 4 - 2 = ?
14 - 5 - 2 = ?
```
- For the first row:
- Start with 35.
- Subtract 11: \( 35 - 11 = 24 \).
- Subtract 13: \( 24 - 13 = 11 \).
- For the second row:
- Start with 8.
- Subtract 4: \( 8 - 4 = 4 \).
- Subtract 2: \( 4 - 2 = 2 \).
- For the third row:
- Start with 14.
- Subtract 5: \( 14 - 5 = 9 \).
- Subtract 2: \( 9 - 2 = 7 \).

Grid Filling:
```
35 - 11 - 13 = 11
8 - 4 - 2 = 2
14 - 5 - 2 = 7
```

Final Answer:

\[
\boxed{
\begin{array}{l}
\text{Puzzle 1: } 34 - 12 - 9 = 13 \\
