Let’s solve each subtraction problem step by step. We’ll go row by row, left to right.
---
First Row:
1. 9080 - 4789
→ 9080 - 4000 = 5080
→ 5080 - 700 = 4380
→ 4380 - 80 = 4300
→ 4300 - 9 =
4291
2. 9070 - 4469
→ 9070 - 4000 = 5070
→ 5070 - 400 = 4670
→ 4670 - 60 = 4610
→ 4610 - 9 =
4601
3. 9060 - 3569
→ 9060 - 3000 = 6060
→ 6060 - 500 = 5560
→ 5560 - 60 = 5500
→ 5500 - 9 =
5491

Second Row:
4. 9080 - 2978
→ 9080 - 2000 = 7080
→ 7080 - 900 = 6180
→ 6180 - 70 = 6110
→ 6110 - 8 =
6102
5. 9050 - 1388
→ 9050 - 1000 = 8050
→ 8050 - 300 = 7750
→ 7750 - 80 = 7670
→ 7670 - 8 =
7662
6. 9040 - 4779
→ 9040 - 4000 = 5040
→ 5040 - 700 = 4340
→ 4340 - 70 = 4270
→ 4270 - 9 =
4261

Third Row:
7. 9060 - 5898
→ 9060 - 5000 = 4060
→ 4060 - 800 = 3260
→ 3260 - 90 = 3170
→ 3170 - 8 =
3162
8. 9080 - 4556
→ 9080 - 4000 = 5080
→ 5080 - 500 = 4580
→ 4580 - 50 = 4530
→ 4530 - 6 =
4524
9. 9040 - 3588
→ 9040 - 3000 = 6040
→ 6040 - 500 = 5540
→ 5540 - 80 = 5460
→ 5460 - 8 =
5452
---
Fourth Row:
10. 9060 - 2978
→ Same as #4 above:
6082? Wait — let’s recalculate carefully!
Wait — earlier I did 9080 - 2978 = 6102. Now it’s 9060 - 2978.
→ 9060 - 2000 = 7060
→ 7060 - 900 = 6160
→ 6160 - 70 = 6090
→ 6090 - 8 =
6082
✔ Corrected:
6082
11. 9070 - 1776
→ 9070 - 1000 = 8070
→ 8070 - 700 = 7370
→ 7370 - 70 = 7300
→ 7300 - 6 =
7294
12. 9060 - 2964
→ 9060 - 2000 = 7060
→ 7060 - 900 = 6160
→ 6160 - 60 = 6100
→ 6100 - 4 =
6096
---
Fifth Row:
13. 9090 - 3743
→ 9090 - 3000 = 6090
→ 6090 - 700 = 5390
→ 5390 - 40 = 5350
→ 5350 - 3 =
5347
14. 9060 - 4279
→ 9060 - 4000 = 5060
→ 5060 - 200 = 4860
→ 4860 - 70 = 4790
→ 4790 - 9 =
4781
15. 9090 - 5968
→ 9090 - 5000 = 4090
→ 4090 - 900 = 3190
→ 3190 - 60 = 3130
→ 3130 - 8 =
3122

Now let’s list all answers in order (left to right, top to bottom):
Row 1: 4291, 4601, 5491
Row 2: 6102, 7662, 4261
Row 3: 3162, 4524, 5452
Row 4: 6082, 7294, 6096
Row 5: 5347, 4781, 3122
Double-checking a few that might be tricky:
- #10: 9060 - 2978 → 9060 - 3000 = 6060, then +22 (because we subtracted 22 too much) → 6060 + 22 = 6082
✔
- #12: 9060 - 2964 → 9060 - 3000 = 6060, then +36 → 6060 + 36 = 6096
✔
- #15: 9090 - 5968 → 9090 - 6000 = 3090, then +32 → 3090 + 32 = 3122
✔
All look correct.
Final Answer:
4291, 4601, 5491, 6102, 7662, 4261, 3162, 4524, 5452, 6082, 7294, 6096, 5347, 4781, 3122
