Step-by-step solution for: Grade 3 Subtraction Worksheets | Free Worksheets | Printables
Let’s solve each subtraction problem step by step.
We’ll go one by one, subtracting the bottom number from the top number in each column.
---
1. 25 - 16
Start with ones: 5 - 6 → can’t do, so borrow from tens.
2 becomes 1, 5 becomes 15.
15 - 6 = 9
Tens: 1 - 1 = 0
→ 9
---
2. 38 - 15
Ones: 8 - 5 = 3
Tens: 3 - 1 = 2
→ 23
---
3. 69 - 28
Ones: 9 - 8 = 1
Tens: 6 - 2 = 4
→ 41
---
4. 60 - 14
Ones: 0 - 4 → can’t do, borrow from tens.
6 becomes 5, 0 becomes 10.
10 - 4 = 6
Tens: 5 - 1 = 4
→ 46
---
5. 87 - 19
Ones: 7 - 9 → can’t do, borrow.
8 becomes 7, 7 becomes 17.
17 - 9 = 8
Tens: 7 - 1 = 6
→ 68
---
6. 49 - 18
Ones: 9 - 8 = 1
Tens: 4 - 1 = 3
→ 31
---
7. 82 - 43
Ones: 2 - 3 → can’t do, borrow.
8 becomes 7, 2 becomes 12.
12 - 3 = 9
Tens: 7 - 4 = 3
→ 39
---
8. 91 - 55
Ones: 1 - 5 → can’t do, borrow.
9 becomes 8, 1 becomes 11.
11 - 5 = 6
Tens: 8 - 5 = 3
→ 36
---
9. 62 - 34
Ones: 2 - 4 → can’t do, borrow.
6 becomes 5, 2 becomes 12.
12 - 4 = 8
Tens: 5 - 3 = 2
→ 28
---
10. 213 - 22
Ones: 3 - 2 = 1
Tens: 1 - 2 → can’t do, borrow from hundreds.
2 becomes 1, 1 becomes 11.
11 - 2 = 9
Hundreds: 1 - 0 = 1
→ 191
---
11. 147 - 93
Ones: 7 - 3 = 4
Tens: 4 - 9 → can’t do, borrow from hundreds.
1 becomes 0, 4 becomes 14.
14 - 9 = 5
Hundreds: 0 - 0 = 0
→ 54
---
12. 274 - 61
Ones: 4 - 1 = 3
Tens: 7 - 6 = 1
Hundreds: 2 - 0 = 2
→ 213
---
13. 332 - 27
Ones: 2 - 7 → can’t do, borrow.
3 becomes 2, 2 becomes 12.
12 - 7 = 5
Tens: 2 - 2 = 0
Hundreds: 3 - 0 = 3
→ 305
---
14. 207 - 29
Ones: 7 - 9 → can’t do, borrow.
0 becomes 9 (after borrowing from hundreds), 7 becomes 17.
Wait — better:
Hundreds: 2 → 1
Tens: 0 → 10, then borrow for ones → tens become 9, ones become 17.
17 - 9 = 8
Tens: 9 - 2 = 7
Hundreds: 1 - 0 = 1
→ 178
---
15. 295 - 83
Ones: 5 - 3 = 2
Tens: 9 - 8 = 1
Hundreds: 2 - 0 = 2
→ 212
---
16. 82 - 46
Ones: 2 - 6 → can’t do, borrow.
8 becomes 7, 2 becomes 12.
12 - 6 = 6
Tens: 7 - 4 = 3
→ 36
---
17. 238 - 96
Ones: 8 - 6 = 2
Tens: 3 - 9 → can’t do, borrow.
2 becomes 1, 3 becomes 13.
13 - 9 = 4
Hundreds: 1 - 0 = 1
→ 142
---
18. 305 - 18
Ones: 5 - 8 → can’t do, borrow.
0 becomes 9 (from hundreds), 5 becomes 15.
15 - 8 = 7
Tens: 9 - 1 = 8
Hundreds: 2 - 0 = 2
→ 287
---
19. 329 - 13
Ones: 9 - 3 = 6
Tens: 2 - 1 = 1
Hundreds: 3 - 0 = 3
→ 316
---
20. 178 - 37
Ones: 8 - 7 = 1
Tens: 7 - 3 = 4
Hundreds: 1 - 0 = 1
→ 141
