Multiplication Problems:
1. 30 × 6
→ 3 × 6 = 18, then add the zero →
180
2. 70 × 9
→ 7 × 9 = 63, then add the zero →
630
3. 80 × 8
→ 8 × 8 = 64, then add the zero →
640
4. 40 × 7
→ 4 × 7 = 28, then add the zero →
280
5. 61 × 9
→ Break it down: (60 × 9) + (1 × 9) = 540 + 9 =
549
6. 71 × 7
→ (70 × 7) + (1 × 7) = 490 + 7 =
497
7. 51 × 6
→ (50 × 6) + (1 × 6) = 300 + 6 =
306
8. 41 × 8
→ (40 × 8) + (1 × 8) = 320 + 8 =
328

Division Problems:
9. 18 ÷ 6
→ How many times does 6 go into 18? 6 × 3 = 18 →
3
10. 40 ÷ 8
→ 8 × 5 = 40 →
5
11. 25 ÷ 5
→ 5 × 5 = 25 →
5
12. 36 ÷ 6
→ 6 × 6 = 36 →
6
13. 14 ÷ 7
→ 7 × 2 = 14 →
2
14. 36 ÷ 9
→ 9 × 4 = 36 →
4
15. 36 ÷ 9 (again) → same as above →
4
16. 50 ÷ 5
→ 5 × 10 = 50 →
10
