Let’s solve each multiplication problem one by one, carefully and step by step.
We’ll go row by row, left to right.

First Row:
1.
788 × 9
Break it down:
- 700 × 9 = 6300
- 80 × 9 = 720
- 8 × 9 = 72
Add them: 6300 + 720 = 7020; 7020 + 72 =
7092
2.
897 × 8
Break it down:
- 800 × 8 = 6400
- 90 × 8 = 720
- 7 × 8 = 56
Add: 6400 + 720 = 7120; 7120 + 56 =
7176
3.
796 × 7
Break it down:
- 700 × 7 = 4900
- 90 × 7 = 630
- 6 × 7 = 42
Add: 4900 + 630 = 5530; 5530 + 42 =
5572

Second Row:
4.
666 × 8
Break it down:
- 600 × 8 = 4800
- 60 × 8 = 480
- 6 × 8 = 48
Add: 4800 + 480 = 5280; 5280 + 48 =
5328
5.
589 × 7
Break it down:
- 500 × 7 = 3500
- 80 × 7 = 560
- 9 × 7 = 63
Add: 3500 + 560 = 4060; 4060 + 63 =
4123
6.
999 × 8
Easy trick: 999 is 1000 - 1
So, 1000 × 8 = 8000, minus 8 =
7992

Third Row:
7.
789 × 4
Break it down:
- 700 × 4 = 2800
- 80 × 4 = 320
- 9 × 4 = 36
Add: 2800 + 320 = 3120; 3120 + 36 =
3156
8.
976 × 9
Break it down:
- 900 × 9 = 8100
- 70 × 9 = 630
- 6 × 9 = 54
Add: 8100 + 630 = 8730; 8730 + 54 =
8784
9.
857 × 6
Break it down:
- 800 × 6 = 4800
- 50 × 6 = 300
- 7 × 6 = 42
Add: 4800 + 300 = 5100; 5100 + 42 =
5142

Fourth Row:
10.
777 × 7
Break it down:
- 700 × 7 = 4900
- 70 × 7 = 490
- 7 × 7 = 49
Add: 4900 + 490 = 5390; 5390 + 49 =
5439
11.
555 × 9
Break it down:
- 500 × 9 = 4500
- 50 × 9 = 450
- 5 × 9 = 45
Add: 4500 + 450 = 4950; 4950 + 45 =
4995
12.
444 × 8
Break it down:
- 400 × 8 = 3200
- 40 × 8 = 320
- 4 × 8 = 32
Add: 3200 + 320 = 3520; 3520 + 32 =
3552
