Let’s solve each multiplication problem one by one. I’ll show the steps so you can follow along easily.
---
1) 92 × 2
Think: 90 × 2 = 180, and 2 × 2 = 4 → 180 + 4 =
184
2) 16 × 4
Break it down: 10 × 4 = 40, 6 × 4 = 24 → 40 + 24 =
64
3) 6 × 81
Do 6 × 80 = 480, then 6 × 1 = 6 → 480 + 6 =
486
4) 5 × 56
5 × 50 = 250, 5 × 6 = 30 → 250 + 30 =
280
5) 70 × 4
7 × 4 = 28, then add a zero →
280
6) 23 × 8
20 × 8 = 160, 3 × 8 = 24 → 160 + 24 =
184
7) 8 × 63
8 × 60 = 480, 8 × 3 = 24 → 480 + 24 =
504
8) 9 × 48
9 × 50 = 450, but we went 2 too far → subtract 9 × 2 = 18 → 450 - 18 =
432
*(Or: 9 × 40 = 360, 9 × 8 = 72 → 360 + 72 = 432)*
9) 55 × 9
55 × 10 = 550, minus 55 → 550 - 55 =
495
10) 39 × 3
40 × 3 = 120, minus 3 → 120 - 3 =
117
11) 1 × 49
Anything times 1 is itself →
49
12) 7 × 84
7 × 80 = 560, 7 × 4 = 28 → 560 + 28 =
588
13) 36 × 8
30 × 8 = 240, 6 × 8 = 48 → 240 + 48 =
288
14) 75 × 9
75 × 10 = 750, minus 75 → 750 - 75 =
675
15) 6 × 25
6 × 20 = 120, 6 × 5 = 30 → 120 + 30 =
150
