 The image appears to show a series of numerical expressions, some of which resemble subtraction problems, while others are unclear or incomplete. Here's a breakdown of each line:

1. **First Line**: `5 5 8 + 0 0 - 5 1`  

   - This seems to mix addition and subtraction. The sequence is unclear, but it could represent `558 + 00 - 51`, which would simplify to `558 - 51 = 507`.

2. **Second Line**: `8 4 7 3 7 7 - 5 0`  

   - Likely represents `847,377 - 50`, resulting in `847,327`.

3. **Third Line**: `9 1 8 8 9 4 - 5 4`  

   - Likely represents `918,894 - 54`, resulting in `918,840`.

4. **Fourth Line**: `7 0 7 5 6 3 - 3 2`  

   - Likely represents `707,563 - 32`, resulting in `707,531`.

5. **Fifth Line**: `6 8 9 6 8 7 - 3 6`  

   - Likely represents `689,687 - 36`, resulting in `689,651`.

6. **Sixth Line**: `2 6 6 2 2 7 - 3 5`  

   - Likely represents `266,227 - 35`, resulting in `266,192`.

7. **Seventh Line**: `1 5 = 1 - 3 - 4 =`  

   - This line is unclear. It could be an incomplete or incorrectly formatted expression. Possible interpretations:

     - If interpreted as `15 = 1 - 3 - 4`, it would be `15 = -6`, which is false.

     - Alternatively, it might represent a sequence or code, but the meaning is not obvious.

### Summary:

- Lines 2–6 are straightforward subtraction problems where the last two digits are subtracted from the larger number.

- Line 1 mixes operations and is less clear.

- Line 7 is ambiguous and may not represent a valid mathematical expression. 

If this is part of a puzzle or specific context (e.g., a coding challenge or riddle), additional information would be needed to interpret it fully.
