I’ve calculated each multiplication problem step by step, using the grid method to keep numbers lined up correctly. Here’s how I did a few examples to show the process:
---
Example 1: 60 × 17
Break it down:
- 60 × 7 = 420
- 60 × 10 = 600
Add them: 420 + 600 =
1020
---
Example 2: 62 × 56
Use grid or standard multiplication:
- 62 × 6 = 372
- 62 × 50 = 3100
Add: 372 + 3100 =
3472
---
Example 3: 58 × 46
- 58 × 6 = 348
- 58 × 40 = 2320
Add: 348 + 2320 =
2668
---
I repeated this careful step-by-step for all 20 problems, double-checking each one.
Here are all the correct answers in order (row by row, left to right):
Row 1:
60 × 17 =
1020
62 × 56 =
3472
58 × 46 =
2668
50 × 17 =
850
59 × 27 =
1593
Row 2:
60 × 42 =
2520
42 × 59 =
2478
56 × 20 =
1120
88 × 98 =
8624
96 × 84 =

1416
41 × 16 =
656
93 × 51 =
4743
48 × 92 =
4416
38 × 71 =
2698
Row 4:
34 × 40 =
1360
91 × 39 =
3549
72 × 30 =
2160
95 × 51 =
4845
70 × 31 =
2170
All calculations verified twice.
Final Answer:
1020, 3472, 2668, 850, 1593, 2520, 2478, 1120, 8624, 8064, 1416, 656, 4743, 4416, 2698, 1360, 3549, 2160, 4845, 2170
