Row 1:
1.
66 × 23
Break it down:
66 × 20 = 1320
66 × 3 = 198
Add them: 1320 + 198 =
1518
2.
14 × 47
14 × 40 = 560
14 × 7 = 98
Add: 560 + 98 =
658
3.
87 × 32
87 × 30 = 2610
87 × 2 = 174
Add: 2610 + 174 =
2784
4.
60 × 48
60 × 40 = 2400
60 × 8 = 480
Add: 2400 + 480 =
2880

Row 2:
5.
48 × 21
48 × 20 = 960
48 × 1 = 48
Add: 960 + 48 =
1008
6.
11 × 71
11 × 70 = 770
11 × 1 = 11
Add: 770 + 11 =
781
7.
36 × 80
36 × 8 = 288 → then add a zero →
2880
8.
23 × 42
23 × 40 = 920
23 × 2 = 46
Add: 920 + 46 =
966

Row 3:
9.
33 × 28
33 × 20 = 660
33 × 8 = 264
Add: 660 + 264 =
924
10.
63 × 27
63 × 20 = 1260
63 × 7 = 441
Add: 1260 + 441 =
1701
11.
26 × 36
26 × 30 = 780
26 × 6 = 156
Add: 780 + 156 =
936
12.
45 × 25
45 × 20 = 900
45 × 5 = 225
Add: 900 + 225 =
1125
---
Row 4:
13.
24 × 30
24 × 3 = 72 → add a zero →
720
14.
46 × 88
Let’s do 46 × 80 = 3680
46 × 8 = 368
Add: 3680 + 368 =
4048
15.
92 × 90
92 × 9 = 828 → add a zero →
8280
16.
76 × 67
76 × 60 = 4560
76 × 7 = 532
Add: 4560 + 532 =
5092
