Subtraction and addition math worksheet for elementary students.

Let’s solve each problem one by one, carefully.

---

Row 1: Subtraction

1. 453 – 64
Start from the right:
3 – 4 → can’t do, borrow from 5 → 13 – 4 = 9
Now 4 (was 5) – 6 → can’t do, borrow from 4 → 14 – 6 = 8
Now 3 (was 4) – 0 = 3
→ 389

2. 273 – 75
3 – 5 → borrow → 13 – 5 = 8
6 (was 7) – 7 → borrow → 16 – 7 = 9
1 (was 2) – 0 = 1
→ 198

3. 839 – 48
9 – 8 = 1
3 – 4 → borrow → 13 – 4 = 9
7 (was 8) – 0 = 7
→ 791

4. 521 – 34
1 – 4 → borrow → 11 – 4 = 7
1 (was 2) – 3 → borrow → 11 – 3 = 8
4 (was 5) – 0 = 4
→ 487

Row 2: Subtraction

5. 152 – 78
2 – 8 → borrow → 12 – 8 = 4
4 (was 5) – 7 → borrow → 14 – 7 = 7
0 (was 1) – 0 = 0 → but we don’t write leading zero → 74

6. 431 – 67
1 – 7 → borrow → 11 – 7 = 4
2 (was 3) – 6 → borrow → 12 – 6 = 6
3 (was 4) – 0 = 3
→ 364

7. 635 – 95
5 – 5 = 0
3 – 9 → borrow → 13 – 9 = 4
5 (was 6) – 0 = 5
→ 540

8. 418 – 29
8 – 9 → borrow → 18 – 9 = 9
0 (was 1) – 2 → borrow → 10 – 2 = 8
3 (was 4) – 0 = 3
→ 389

Row 3: Addition

9. 240 + 61
0 + 1 = 1
4 + 6 = 10 → write 0, carry 1
2 + 0 + 1 = 3
→ 301

10. 645 + 58
5 + 8 = 13 → write 3, carry 1
4 + 5 + 1 = 10 → write 0, carry 1
6 + 0 + 1 = 7
→ 703

11. 758 + 73
8 + 3 = 11 → write 1, carry 1
5 + 7 + 1 = 13 → write 3, carry 1
7 + 0 + 1 = 8
→ 831

12. 541 + 89
1 + 9 = 10 → write 0, carry 1
4 + 8 + 1 = 13 → write 3, carry 1
5 + 0 + 1 = 6
→ 630

Row 4: Addition

13. 137 + 67
7 + 7 = 14 → write 4, carry 1
3 + 6 + 1 = 10 → write 0, carry 1
1 + 0 + 1 = 2
→ 204

14. 254 + 78
4 + 8 = 12 → write 2, carry 1
5 + 7 + 1 = 13 → write 3, carry 1
2 + 0 + 1 = 3
→ 332

15. 718 + 92
8 + 2 = 10 → write 0, carry 1
1 + 9 + 1 = 11 → write 1, carry 1
7 + 0 + 1 = 8
→ 810

16. 899 + 34
9 + 4 = 13 → write 3, carry 1
9 + 3 + 1 = 13 → write 3, carry 1
8 + 0 + 1 = 9
→ 933

Final Answer:
389, 198, 791, 487, 74, 364, 540, 389, 301, 703, 831, 630, 204, 332, 810, 933
