Let’s solve each multiplication problem one by one. We’ll go row by row, left to right.
---
Row 1:
- 27 × 4
→ 20×4 = 80, 7×4 = 28 → 80 + 28 =
108
- 32 × 3
→ 30×3 = 90, 2×3 = 6 → 90 + 6 =
96
- 66 × 2
→ 60×2 = 120, 6×2 = 12 → 120 + 12 =
132
- 51 × 8
→ 50×8 = 400, 1×8 = 8 → 400 + 8 =
408
- 39 × 3
→ 30×3 = 90, 9×3 = 27 → 90 + 27 =
117
---
Row 2:
- 42 × 1 =
42 (anything times 1 is itself)
- 30 × 8
→ 3×8 = 24, then add a zero →
240
- 48 × 7
→ 40×7 = 280, 8×7 = 56 → 280 + 56 =
336
- 32 × 4
→ 30×4 = 120, 2×4 = 8 → 120 + 8 =
128
- 58 × 2
→ 50×2 = 100, 8×2 = 16 → 100 + 16 =
116
---
Row 3:
- 69 × 3
→ 60×3 = 180, 9×3 = 27 → 180 + 27 =
207
- 31 × 3
→ 30×3 = 90, 1×3 = 3 → 90 + 3 =
93
- 27 × 1 =
27
- 19 × 9
→ 10×9 = 90, 9×9 = 81 → 90 + 81 =
171
- 10 × 8 =
80
---
Row 4:
- 32 × 4
→ Same as before →
128
- 25 × 7
→ 20×7 = 140, 5×7 = 35 → 140 + 35 =
175
- 36 × 8
→ 30×8 = 240, 6×8 = 48 → 240 + 48 =
288
- 33 × 7
→ 30×7 = 210, 3×7 = 21 → 210 + 21 =
231
- 81 × 2
→ 80×2 = 160, 1×2 = 2 → 160 + 2 =
162
---
Row 5:
- 63 × 9
→ 60×9 = 540, 3×9 = 27 → 540 + 27 =
567
- 38 × 8
→ 30×8 = 240, 8×8 = 64 → 240 + 64 =
304
- 24 × 5
→ 20×5 = 100, 4×5 = 20 → 100 + 20 =
120
- 30 × 9
→ 3×9 = 27, add a zero →
270
- 95 × 9
→ 90×9 = 810, 5×9 = 45 → 810 + 45 =
855
---
Row 6:
- 32 × 2
→ 30×2 = 60, 2×2 = 4 → 60 + 4 =
64
- 64 × 3
→ 60×3 = 180, 4×3 = 12 → 180 + 12 =
192
- 84 × 6
→ 80×6 = 480, 4×6 = 24 → 480 + 24 =
504
- 70 × 4
→ 7×4 = 28, add a zero →
280
- 16 × 8
→ 10×8 = 80, 6×8 = 48 → 80 + 48 =
128
