Part 1: Multiplication Problems

We'll compute each multiplication:

1. $ 12 \times 23 $
- $ 12 \times 20 = 240 $
- $ 12 \times 3 = 36 $
- $ 240 + 36 = 276 $
- ✔ 276

2. $ 15 \times 14 $
- $ 15 \times 10 = 150 $
- $ 15 \times 4 = 60 $
- $ 150 + 60 = 210 $
- ✔ 210

3. $ 20 \times 11 $
- $ 20 \times 10 = 200 $
- $ 20 \times 1 = 20 $
- $ 200 + 20 = 220 $
- ✔ 220

4. $ 18 \times 10 $
- Any number × 10 = that number with a zero added
- ✔ 180

5. $ 16 \times 20 $
- $ 16 \times 2 = 32 $, then add a zero → $ 320 $
- ✔ 320

6. $ 17 \times 12 $
- $ 17 \times 10 = 170 $
- $ 17 \times 2 = 34 $
- $ 170 + 34 = 204 $
- ✔ 204

7. $ 11 \times 22 $
- $ 11 \times 20 = 220 $
- $ 11 \times 2 = 22 $
- $ 220 + 22 = 242 $
- ✔ 242

8. $ 13 \times 17 $
- $ 13 \times 10 = 130 $
- $ 13 \times 7 = 91 $
- $ 130 + 91 = 221 $
- ✔ 221

9. $ 21 \times 14 $
- $ 21 \times 10 = 210 $
- $ 21 \times 4 = 84 $
- $ 210 + 84 = 294 $
- ✔ 294

10. $ 19 \times 19 $
- This is $ 19^2 $
- $ (20 - 1)^2 = 400 - 40 + 1 = 361 $
- Or: $ 19 \times 10 = 190 $, $ 19 \times 9 = 171 $, $ 190 + 171 = 361 $
- ✔ 361

Part 2: Division Problems

Now, let's do the division problems:

1. $ 88 \div 22 $
- $ 22 \times 4 = 88 $
- ✔ 4

2. $ 42 \div 21 $
- $ 21 \times 2 = 42 $
- ✔ 2

3. $ 96 \div 12 $
- $ 12 \times 8 = 96 $
- ✔ 8

4. $ 60 \div 15 $
- $ 15 \times 4 = 60 $
- ✔ 4

5. $ 63 \div 21 $
- $ 21 \times 3 = 63 $
- ✔ 3

---

Part 3: Mixed Problems (More Division & Multiplication)

1. $ 264 \div 22 $
- Let's divide:
- $ 22 \times 10 = 220 $
- $ 264 - 220 = 44 $
- $ 22 \times 2 = 44 $
- So $ 10 + 2 = 12 $
- ✔ 12

2. $ 325 \div 13 $
- Try: $ 13 \times 20 = 260 $
- $ 325 - 260 = 65 $
- $ 13 \times 5 = 65 $
- So $ 20 + 5 = 25 $
- ✔ 25

3. $ 144 \div 12 $
- $ 12 \times 12 = 144 $
- ✔ 12

4. $ 224 \div 14 $
- $ 14 \times 10 = 140 $
- $ 224 - 140 = 84 $
- $ 14 \times 6 = 84 $
- $ 10 + 6 = 16 $
- ✔ 16

5. $ 170 \div 10 $
- Dividing by 10: move decimal one place left
- ✔ 17

6. $ 255 \div 15 $
- $ 15 \times 10 = 150 $
- $ 255 - 150 = 105 $
- $ 15 \times 7 = 105 $
- $ 10 + 7 = 17 $
- ✔ 17

7. $ 25 \times 16 $
- $ 25 \times 10 = 250 $
- $ 25 \times 6 = 150 $
- $ 250 + 150 = 400 $
- ✔ 400

8. $ 14 \times 28 $
- Break it down:
- $ 14 \times 20 = 280 $
- $ 14 \times 8 = 112 $
- $ 280 + 112 = 392 $
- ✔ 392

9. $ 12 \times 31 $
- $ 12 \times 30 = 360 $
- $ 12 \times 1 = 12 $
- $ 360 + 12 = 372 $
- ✔ 372
