1) 43 × 4
40 × 4 = 160
3 × 4 = 12
160 + 12 =
172
2) 97 × 8
90 × 8 = 720
7 × 8 = 56
720 + 56 =
776
3) 85 × 7
80 × 7 = 560
5 × 7 = 35
560 + 35 =
595
4) 71 × 8
70 × 8 = 560
1 × 8 = 8
560 + 8 =
568
5) 28 × 6
20 × 6 = 120
8 × 6 = 48
120 + 48 =
168
6) 96 × 8
90 × 8 = 720
6 × 8 = 48
720 + 48 =
768
7) 65 × 2
60 × 2 = 120
5 × 2 = 10
120 + 10 =
130
8) 80 × 5
8 × 5 = 40, so 80 × 5 =
400
9) 23 × 2
20 × 2 = 40
3 × 2 = 6
40 + 6 =
46
10) 60 × 7
6 × 7 = 42, so 60 × 7 =
420
11) 92 × 8
90 × 8 = 720
2 × 8 = 16
720 + 16 =
736
12) 43 × 9
40 × 9 = 360
3 × 9 = 27
360 + 27 =
387
13) 75 × 7
70 × 7 = 490
5 × 7 = 35
490 + 35 =
525
14) 60 × 7
Same as #10 →
420
15) 91 × 3
90 × 3 = 270
1 × 3 = 3
270 + 3 =
273
16) 70 × 8
7 × 8 = 56, so 70 × 8 =
560
17) 87 × 9
80 × 9 = 720
7 × 9 = 63
720 + 63 =
783
18) 38 × 4
30 × 4 = 120
8 × 4 = 32
120 + 32 =
152
19) 33 × 7
30 × 7 = 210
3 × 7 = 21
210 + 21 =
231
20) 65 × 5
60 × 5 = 300
5 × 5 = 25
300 + 25 =
325
