Let’s solve each subtraction problem step by step. We’re subtracting a smaller number from a larger whole thousand (like 5,000, 6,000, etc.). We’ll do them one at a time and double-check our work.

1. 5,000 – 195
Start with 5,000. Subtract 200 → that gives 4,800. But we only need to subtract 195, which is 5 less than 200. So add back 5: 4,800 + 5 =
4,805
✔ Check: 4,805 + 195 = 5,000 → Correct!
---
2. 6,000 – 303
Subtract 300 → 5,700. Then subtract 3 more → 5,697
✔ Check: 5,697 + 303 = 6,000 → Correct!
---
3. 3,000 – 507
Subtract 500 → 2,500. Then subtract 7 → 2,493
✔ Check: 2,493 + 507 = 3,000 → Correct!
---
4. 8,000 – 783
Subtract 700 → 7,300. Subtract 80 → 7,220. Subtract 3 → 7,217
✔ Check: 7,217 + 783 = 8,000 → Correct!
---
5. 9,000 – 392
Subtract 400 → 8,600. Add back 8 (since we subtracted 8 too many) → 8,608
✔ Check: 8,608 + 392 = 9,000 → Correct!
---
6. 2,000 – 716
Subtract 700 → 1,300. Subtract 16 → 1,284
✔ Check: 1,284 + 716 = 2,000 → Correct!
---
7. 8,000 – 283
Subtract 300 → 7,700. Add back 17 → 7,717
✔ Check: 7,717 + 283 = 8,000 → Correct!
---
8. 1,000 – 120
Easy! 1,000 – 100 = 900; 900 – 20 =
880
✔ Check: 880 + 120 = 1,000 → Correct!
---
9. 4,000 – 419
Subtract 400 → 3,600. Subtract 19 → 3,581
✔ Check: 3,581 + 419 = 4,000 → Correct!
---
10. 6,000 – 152
Subtract 100 → 5,900. Subtract 50 → 5,850. Subtract 2 → 5,848
✔ Check: 5,848 + 152 = 6,000 → Correct!
---
11. 5,000 – 632
Subtract 600 → 4,400. Subtract 32 → 4,368
✔ Check: 4,368 + 632 = 5,000 → Correct!
---
12. 7,000 – 912
Subtract 900 → 6,100. Subtract 12 → 6,088
✔ Check: 6,088 + 912 = 7,000 → Correct!
---
13. 7,000 – 824
Subtract 800 → 6,200. Subtract 24 → 6,176
✔ Check: 6,176 + 824 = 7,000 → Correct!
---
14. 4,000 – 891
Subtract 900 → 3,100. Add back 9 → 3,109
✔ Check: 3,109 + 891 = 4,000 → Correct!
---
15. 1,000 – 836
Subtract 800 → 200. Subtract 36 → 164
✔ Check: 164 + 836 = 1,000 → Correct!
---
16. 6,000 – 454
Subtract 400 → 5,600. Subtract 54 → 5,546
✔ Check: 5,546 + 454 = 6,000 → Correct!
---
17. 1,000 – 980
That’s just 20 left! Because 980 + 20 = 1,000 →
20
✔ Check: 20 + 980 = 1,000 → Correct!
---
18. 4,000 – 387
Subtract 400 → 3,600. Add back 13 → 3,613
✔ Check: 3,613 + 387 = 4,000 → Correct!
---
19. 1,000 – 381
Subtract 300 → 700. Subtract 81 → 619
✔ Check: 619 + 381 = 1,000 → Correct!
---
20. 6,000 – 122
Subtract 100 → 5,900. Subtract 22 → 5,878
✔ Check: 5,878 + 122 = 6,000 → Correct!
