Grade 4 Maths Resources (1.5.1 Subtraction of 5 Digit Numbers with ... - Free Printable

Let’s solve each subtraction problem step by step. We’ll go one at a time, carefully subtracting the bottom number from the top number.

Problem 1: 55645 - 23526

Start from the rightmost digit:

- 5 - 6 → can’t do, borrow → 15 - 6 = 9
- 3 (after borrowing) - 2 = 1
- 6 - 5 = 1
- 5 - 3 = 2
- 5 - 2 = 3

→ 32119

Check: 23526 + 32119 = 55645 ✔

Problem 2: 74580 - 28757

- 0 - 7 → borrow → 10 - 7 = 3
- 7 (after borrow) - 5 = 2
- 5 - 7 → borrow → 15 - 7 = 8
- 3 (after borrow) - 8 → borrow → 13 - 8 = 5
- 6 (after borrow) - 2 = 4

→ 45823

Check: 28757 + 45823 = 74580 ✔

Problem 3: 68449 - 42087

- 9 - 7 = 2
- 4 - 8 → borrow → 14 - 8 = 6
- 3 (after borrow) - 0 = 3
- 8 - 2 = 6
- 6 - 4 = 2

→ 26362

Check: 42087 + 26362 = 68449 ✔

---

Problem 4: 25671 - 24543

- 1 - 3 → borrow → 11 - 3 = 8
- 6 (after borrow) - 4 = 2
- 6 - 5 = 1
- 5 - 4 = 1
- 2 - 2 = 0

→ 1128

Check: 24543 + 1128 = 25671 ✔

---

Problem 5: 42678 - 30556

- 8 - 6 = 2
- 7 - 5 = 2
- 6 - 5 = 1
- 2 - 0 = 2
- 4 - 3 = 1

→ 12122

Check: 30556 + 12122 = 42678 ✔

---

Problem 6: 63676 - 35422

- 6 - 2 = 4
- 7 - 2 = 5
- 6 - 4 = 2
- 3 - 5 → borrow → 13 - 5 = 8
- 5 (after borrow) - 3 = 2

→ 28254

Check: 35422 + 28254 = 63676 ✔

Problem 7: 50220 - 24159

- 0 - 9 → borrow → 10 - 9 = 1
- 1 (after borrow) - 5 → borrow → 11 - 5 = 6
- 1 (after borrow) - 1 = 0
- 9 (after borrow from 5→4, then 0→9? Wait — let’s redo carefully)

Actually:

Write it out:

```
50220
- 24159
-------
```

Right to left:

- 0 - 9 → borrow from 2 → becomes 10 - 9 = 1; tens place is now 1
- 1 - 5 → borrow from hundreds (which is 2 → becomes 1), so 11 - 5 = 6
- 1 (hundreds) - 1 = 0
- 0 (thousands) - 4 → need to borrow from ten-thousands (5 → 4), so 10 - 4 = 6
- 4 (ten-thousands) - 2 = 2

Wait — that gives 26061? Let me check again.

Better way:

Use column subtraction with borrowing:

```
5 0 2 2 0
- 2 4 1 5 9
------------
```

Step-by-step:

Units: 0 < 9 → borrow from tens. Tens is 2 → becomes 1, units become 10 → 10 - 9 = 1

Tens: 1 (after borrow) < 5 → borrow from hundreds. Hundreds is 2 → becomes 1, tens become 11 → 11 - 5 = 6

Hundreds: 1 (after borrow) - 1 = 0

Thousands: 0 < 4 → borrow from ten-thousands. Ten-thousands is 5 → becomes 4, thousands become 10 → 10 - 4 = 6

Ten-thousands: 4 - 2 = 2

So result: 26061

Check: 24159 + 26061 = 50220 ✔

Problem 8: 36724 - 18360

- 4 - 0 = 4
- 2 - 6 → borrow → 12 - 6 = 6
- 6 (after borrow) - 3 = 3
- 6 - 8 → borrow → 16 - 8 = 8
- 2 (after borrow) - 1 = 1

→ 18364

Check: 18360 + 18364 = 36724 ✔

---

Problem 9: 78648 - 35234

- 8 - 4 = 4
- 4 - 3 = 1
- 6 - 2 = 4
- 8 - 5 = 3
- 7 - 3 = 4

→ 43414

Check: 35234 + 43414 = 78648 ✔

Problem 10: 46537 - 24484

- 7 - 4 = 3
- 3 - 8 → borrow → 13 - 8 = 5
- 4 (after borrow) - 4 = 0
- 6 - 4 = 2
- 4 - 2 = 2

→ 22053

Check: 24484 + 22053 = 46537 ✔

---

Problem 11: 82381 - 75660

- 1 - 0 = 1
- 8 - 6 = 2
- 3 - 6 → borrow → 13 - 6 = 7
- 1 (after borrow) - 5 → borrow → 11 - 5 = 6
- 7 (after borrow) - 7 = 0

→ 6721

Check: 75660 + 6721 = 82381 ✔

Problem 12: 90000 - 23358

This one needs multiple borrows.

```
90000
- 23358
-------
```

Units: 0 - 8 → borrow → but all zeros until 9.

Borrow chain:

Ten-thousands: 9 → becomes 8
Thousands: 0 → becomes 10, but we need to lend to hundreds → becomes 9
Hundreds: 0 → becomes 10, lend to tens → becomes 9
Tens: 0 → becomes 10, lend to units → becomes 9
Units: 10 - 8 = 2

Now:

Tens: 9 - 5 = 4
Hundreds: 9 - 3 = 6
Thousands: 9 - 3 = 6
Ten-thousands: 8 - 2 = 6

→ 66642

Check: 23358 + 66642 = 90000 ✔

Problem 13: 67236 - 20018

- 6 - 8 → borrow → 16 - 8 = 8
- 2 (after borrow) - 1 = 1
- 2 - 0 = 2
- 7 - 0 = 7
- 6 - 2 = 4

→ 47218

Check: 20018 + 47218 = 67236 ✔

Problem 14: 94364 - 34252

- 4 - 2 = 2
- 6 - 5 = 1
- 3 - 2 = 1
- 4 - 4 = 0
- 9 - 3 = 6

→ 60112

Check: 34252 + 60112 = 94364 ✔

---

Problem 15: 53699 - 22879

- 9 - 9 = 0
- 9 - 7 = 2
- 6 - 8 → borrow → 16 - 8 = 8
- 2 (after borrow) - 2 = 0
- 5 - 2 = 3

→ 30820

Check: 22879 + 30820 = 53699 ✔
