Let’s solve each subtraction problem step by step. We’ll go from right to left (ones place to hundred thousands), borrowing when needed.

Problem 1:
```
L TTh Th H T O
8 2 1 0 2 5
- 4 2 5 0 1 3
----------------
```
Start from the ones place:
- Ones: 5 - 3 =
2
- Tens: 2 - 1 =
1
- Hundreds: 0 - 0 =
0
- Thousands: 1 - 5 → can’t do, borrow from ten thousands.
- Ten thousands is 2 → becomes 1, thousands become 11.
- 11 - 5 =
6
- Ten thousands: now 1 (after borrowing) - 2 → can’t do, borrow from lakhs.
- Lakhs is 8 → becomes 7, ten thousands become 11.
- 11 - 2 =
9
- Lakhs: 7 - 4 =
3

Problem 2:
```
L TTh Th H T O
5 0 0 0 0 0
- 2 0 0 0 0 0
----------------
```
This is straightforward — no borrowing needed.
- All digits subtract directly:
- 5 - 2 = 3 in lakhs place
- Rest are 0 - 0 = 0

Problem 3:
```
L TTh Th H T O
7 4 5 0 3 0
- 5 9 6 2 0 1
----------------
```
Ones: 0 - 1 → borrow from tens. But tens is 3 → becomes 2, ones become 10.
→ 10 - 1 =
9
Tens: now 2 - 0 =
2
Hundreds: 0 - 2 → borrow from thousands. Thousands is 5 → becomes 4, hundreds become 10.
→ 10 - 2 =
8
Thousands: now 4 - 6 → borrow from ten thousands. Ten thousands is 4 → becomes 3, thousands become 14.
→ 14 - 6 =
8
Ten thousands: now 3 - 9 → borrow from lakhs. Lakhs is 7 → becomes 6, ten thousands become 13.
→ 13 - 9 =
4
Lakhs: 6 - 5 =
1

Problem 4:
```
L TTh Th H T O
3 9 8 7 2 2
- 1 0 0 8 1 1
----------------
```
Ones: 2 - 1 =
1
Tens: 2 - 1 =
1
Hundreds: 7 - 8 → borrow from thousands. Thousands is 8 → becomes 7, hundreds become 17.
→ 17 - 8 =
9
Thousands: now 7 - 0 =
7
Ten thousands: 9 - 0 =
9
Lakhs: 3 - 1 =
2

Problem 5:
```
L TTh Th H T O
4 8 8 5 9 1
- 2 5 7 0 3 2
----------------
```
Ones: 1 - 2 → borrow from tens. Tens is 9 → becomes 8, ones become 11.
→ 11 - 2 =
9
Tens: now 8 - 3 =
5
Hundreds: 5 - 0 =
5
Thousands: 8 - 7 =
1
Ten thousands: 8 - 5 =
3
Lakhs: 4 - 2 =
2

Problem 6:
```
L TTh Th H T O
6 0 3 4 2 0
- 4 7 2 6 3 0
----------------
```
Ones: 0 - 0 =
0
Tens: 2 - 3 → borrow from hundreds. Hundreds is 4 → becomes 3, tens become 12.
→ 12 - 3 =
9
Hundreds: now 3 - 6 → borrow from thousands. Thousands is 3 → becomes 2, hundreds become 13.
→ 13 - 6 =
7
Thousands: now 2 - 2 =
0
Ten thousands: 0 - 7 → borrow from lakhs. Lakhs is 6 → becomes 5, ten thousands become 10.
→ 10 - 7 =
3
Lakhs: 5 - 4 =
1
