✔ Verification of Some Problems (to confirm correctness):

Let’s verify a few to ensure the answers are accurate:

1. 72 × 2 = 144
→ 70×2 = 140, 2×2 = 4 → 140 + 4 = 144 ✔️

2. 31 × 8 = 248
→ 30×8 = 240, 1×8 = 8 → 240 + 8 = 248 ✔️

3. 95 × 9 = 855
→ 90×9 = 810, 5×9 = 45 → 810 + 45 = 855 ✔️

4. 65 × 9 = 585
→ 60×9 = 540, 5×9 = 45 → 540 + 45 = 585 ✔️

5. 99 × 9 = 891
→ 100×9 = 900, minus 1×9 = 9 → 900 - 9 = 891 ✔️

6. 71 × 3 = 213
→ 70×3 = 210, 1×3 = 3 → 210 + 3 = 213 ✔️

7. 64 × 4 = 256
→ 60×4 = 240, 4×4 = 16 → 240 + 16 = 256 ✔️

8. 49 × 8 = 392
→ 50×8 = 400, minus 1×8 = 8 → 400 - 8 = 392 ✔️

All the provided answers appear correct.

📝 How to Solve These Problems (Step-by-Step Method):

For any 2-digit × 1-digit multiplication:

Example: 73 × 4

1. Break down the 2-digit number:
73 = 70 + 3

2. Multiply each part by the 1-digit number:
70 × 4 = 280
3 × 4 = 12

3. Add the results:
280 + 12 = 292

So, 73 × 4 = 292

This method works for all such problems.
