Let’s solve each multiplication problem step by step.
We are multiplying 20 by numbers from 0 to 12.
Remember:
Multiplying by 0 always gives 0.
Multiplying by 1 gives the same number.
For others, you can think of it as adding 20 that many times — or just multiply 2 × the number and add a zero at the end (since 20 = 2 × 10).
Let’s go one by one:
- 20 × 0 = 0
- 20 × 1 = 20
- 20 × 2 = 40
- 20 × 3 = 60
- 20 × 4 = 80
- 20 × 5 = 100
- 20 × 6 = 120
- 20 × 7 = 140
- 20 × 8 = 160
- 20 × 9 = 180
- 20 × 10 = 200
- 20 × 11 = 220
- 20 × 12 = 240
Double-checking a few:
→ 20 × 5: 5 + 5 + 5 + 5 + 5 = 25 → then ×10? Wait, better: 2×5=10 → add 0 → 100 ✔️
→ 20 × 12: 2×12=24 → add 0 → 240 ✔️
→ 20 × 0 = 0 ✔️
→ 20 × 10 = 200 ✔️
All look correct.
Final Answer:
20 × 0 = 0
20 × 1 = 20
20 × 2 = 40
20 × 3 = 60
20 × 4 = 80
20 × 5 = 100
20 × 6 = 120
20 × 7 = 140
20 × 8 = 160
20 × 9 = 180
20 × 10 = 200
20 × 11 = 220
20 × 12 = 240
