Let’s solve each multiplication problem one by one. We’ll go row by row, left to right.
---
Row 1:
1.
23 × 4
→ 20 × 4 = 80
→ 3 × 4 = 12
→ 80 + 12 =
92
2.
49 × 7
→ 50 × 7 = 350 (but we have 49, so subtract 7)
→ 350 - 7 =
343
3.
32 × 5
→ 30 × 5 = 150
→ 2 × 5 = 10
→ 150 + 10 =
160
4.
66 × 6
→ 60 × 6 = 360
→ 6 × 6 = 36
→ 360 + 36 =
396
---
Row 2:
5.
34 × 2
→ 30 × 2 = 60
→ 4 × 2 = 8
→ 60 + 8 =
68
6.
72 × 8
→ 70 × 8 = 560
→ 2 × 8 = 16
→ 560 + 16 =
576
7.
33 × 6
→ 30 × 6 = 180
→ 3 × 6 = 18
→ 180 + 18 =
198
8.
45 × 5
→ 40 × 5 = 200
→ 5 × 5 = 25
→ 200 + 25 =
225
---
Row 3:
9.
40 × 8
→ 4 × 8 = 32, then add a zero →
320
10.
30 × 9
→ 3 × 9 = 27, then add a zero →
270
11.
42 × 8
→ 40 × 8 = 320
→ 2 × 8 = 16
→ 320 + 16 =
336
12.
24 × 7
→ 20 × 7 = 140
→ 4 × 7 = 28
→ 140 + 28 =
168
---
Row 4:
13.
10 × 8
→ Just add a zero to 8 →
80
14.
63 × 8
→ 60 × 8 = 480
→ 3 × 8 = 24
→ 480 + 24 =
504
15.
91 × 8
→ 90 × 8 = 720
→ 1 × 8 = 8
→ 720 + 8 =
728
16.
37 × 5
→ 30 × 5 = 150
→ 7 × 5 = 35
→ 150 + 35 =
185
---
Row 5:
17.
86 × 3
→ 80 × 3 = 240
→ 6 × 3 = 18
→ 240 + 18 =
258
18.
55 × 4
→ 50 × 4 = 200
→ 5 × 4 = 20
→ 200 + 20 =
220
19.
60 × 2
→ 6 × 2 = 12, then add a zero →
120
20.
51 × 4
→ 50 × 4 = 200
→ 1 × 4 = 4
→ 200 + 4 =
204
