Let’s solve each subtraction problem one by one. We’re subtracting a 3-digit number from a 4-digit number. We’ll do this column by column, starting from the right (ones place), and borrow if needed.

Row 1:
1. 1847 – 661
- Ones: 7 – 1 = 6
- Tens: 4 – 6 → can’t do, borrow from hundreds → 14 – 6 = 8 (hundreds becomes 7)
- Hundreds: 7 – 6 = 1
- Thousands: 1 – 0 = 1
→ 1186
2. 4370 – 301
- Ones: 0 – 1 → borrow → 10 – 1 = 9 (tens becomes 6)
- Tens: 6 – 0 = 6
- Hundreds: 3 – 3 = 0
- Thousands: 4 – 0 = 4
→ 4069
3. 3221 – 110

- Hundreds: 6 – 7 → borrow → 16 – 7 = 9 (thousands becomes 0)
- Thousands: 0 – 0 = 0 → so it’s 989
→ 989
5. 1332 – 589
- Ones: 2 – 9 → borrow → 12 – 9 = 3 (tens becomes 2)
- Tens: 2 – 8 → borrow → 12 – 8 = 4 (hundreds becomes 2)
- Hundreds: 2 – 5 → borrow → 12 – 5 = 7 (thousands becomes 0)

- Hundreds: 9 – 9 = 0
- Thousands: 4 – 0 = 4 → but wait, we borrowed from thousands? Let’s recheck:
Actually:
4014 – 953
Ones: 4 – 3 = 1
Tens: 1 – 5 → borrow from hundreds → but hundreds is 0 → borrow from thousands
So:
Thousands: 4 → 3
Hundreds: 0 → 10 → then lend to tens → becomes 9
Tens: 1 → 11 → 11 – 5 = 6
Hundreds: 9 – 9 = 0
Thousands: 3 – 0 = 3
→ 3061
Wait — let me recalculate carefully:
4014
– 953
------
Start from right:
Ones: 4 – 3 = 1
Tens: 1 – 5 → can’t → borrow from hundreds → but hundreds is 0 → so borrow from thousands
Thousands: 4 → 3
Hundreds: 0 → 10 → now lend to tens → hundreds becomes 9, tens becomes 11
Tens: 11 – 5 = 6
Hundreds: 9 – 9 = 0
Thousands: 3 – 0 = 3
→ 3061
Yes.

- Ones: 4 – 3 = 1
- Tens: 1 – 5 → borrow → 11 – 5 = 6 (hundreds becomes 9)
- Hundreds: 9 – 9 = 0
- Thousands: 4 – 0 = 4 → but wait, we borrowed from thousands? Let’s recheck:
Actually:
4014 – 953
Ones: 4 – 3 = 1
Tens: 1 – 5 → borrow from hundreds → but hundreds is 0 → borrow from thousands
So:
Thousands: 4 → 3
Hundreds: 0 → 10 → then lend to tens → becomes 9
Tens: 1 → 11 → 11 – 5 = 6
Hundreds: 9 – 9 = 0
Thousands: 3 – 0 = 3
→ 3061
Wait — let me recalculate carefully:
4014
– 953
------
Start from right:
Ones: 4 – 3 = 1
Tens: 1 – 5 → can’t → borrow from hundreds → but hundreds is 0 → so borrow from thousands
Thousands: 4 → 3
Hundreds: 0 → 10 → now lend to tens → hundreds becomes 9, tens becomes 11
Tens: 11 – 5 = 6
Hundreds: 9 – 9 = 0
Thousands: 3 – 0 = 3
→ 3061
Yes.
