🔹 Problem 1: Already Solved (for reference)

```
Th H T O
9 7 9 9
- 5 2 6 8
_________
4 5 3 1
```
✔ This is correct:
- 9 - 8 = 1 (Ones)
- 9 - 6 = 3 (Tens)
- 7 - 2 = 5 (Hundreds)
- 9 - 5 = 4 (Thousands)

Now, let’s solve the rest:

🔹 Problem 2:

```
Th H T O
7 7 9 3
- 7 7 6 0
_________
```

Subtract column by column from right to left:

- Ones: 3 - 0 = 3
- Tens: 9 - 6 = 3
- Hundreds: 7 - 7 = 0
- Thousands: 7 - 7 = 0

✔ Answer: 0 0 3 3 → 33

> But since it's a 4-digit number, write it as 0033, but usually we just write 33.

But in context, keep it aligned as:
```
0 0 3 3
```

So, Answer: 0033 → 33

🔹 Problem 3:

```
Th H T O
4 5 6 4

So:
```
4 5 6 4
- 0 5 0 4
_________
```

- Ones: 4 - 4 = 0
- Tens: 6 - 0 = 6
- Hundreds: 5 - 5 = 0
