1. 856 − 669

#### Step-by-Step Solution:
```
856
- 669
------
```
- Units place: 6 − 9 is not possible, so we borrow 1 from the tens place.
- After borrowing, 6 becomes 16, and 5 in the tens place becomes 4.
- Now, 16 − 9 = 7.
- Tens place: 4 − 6 is not possible, so we borrow 1 from the hundreds place.
- After borrowing, 4 becomes 14, and 8 in the hundreds place becomes 7.
- Now, 14 − 6 = 8.
- Hundreds place: 7 − 6 = 1.

Final result: 187

2. 287 − 188

#### Step-by-Step Solution:
```
287
- 188
------
```
- Units place: 7 − 8 is not possible, so we borrow 1 from the tens place.
- After borrowing, 7 becomes 17, and 8 in the tens place becomes 7.
- Now, 17 − 8 = 9.
- Tens place: 7 − 8 is not possible, so we borrow 1 from the hundreds place.
- After borrowing, 7 becomes 17, and 2 in the hundreds place becomes 1.
- Now, 17 − 8 = 9.
- Hundreds place: 1 − 1 = 0.

Final result: 99

3. 336 − 119

#### Step-by-Step Solution:
```
336
- 119
------
```
- Units place: 6 − 9 is not possible, so we borrow 1 from the tens place.
- After borrowing, 6 becomes 16, and 3 in the tens place becomes 2.
- Now, 16 − 9 = 7.
- Tens place: 2 − 1 = 1.
- Hundreds place: 3 − 1 = 2.

Final result: 217

4. 443 − 295

#### Step-by-Step Solution:
```
443
- 295
------
```
- Units place: 3 − 5 is not possible, so we borrow 1 from the tens place.
- After borrowing, 3 becomes 13, and 4 in the tens place becomes 3.
- Now, 13 − 5 = 8.
- Tens place: 3 − 9 is not possible, so we borrow 1 from the hundreds place.
- After borrowing, 3 becomes 13, and 4 in the hundreds place becomes 3.
- Now, 13 − 9 = 4.
- Hundreds place: 3 − 2 = 1.

Final result: 148

5. 525 − 336

#### Step-by-Step Solution:
```
525
- 336
------
```
- Units place: 5 − 6 is not possible, so we borrow 1 from the tens place.
- After borrowing, 5 becomes 15, and 2 in the tens place becomes 1.
- Now, 15 − 6 = 9.
- Tens place: 1 − 3 is not possible, so we borrow 1 from the hundreds place.
- After borrowing, 1 becomes 11, and 5 in the hundreds place becomes 4.
- Now, 11 − 3 = 8.
- Hundreds place: 4 − 3 = 1.

Final result: 189

6. 977 − 679

#### Step-by-Step Solution:
```
977
- 679
------
```
- Units place: 7 − 9 is not possible, so we borrow 1 from the tens place.
- After borrowing, 7 becomes 17, and 7 in the tens place becomes 6.
- Now, 17 − 9 = 8.
- Tens place: 6 − 7 is not possible, so we borrow 1 from the hundreds place.
