Row 1:

1. 444 × 312
- Break it down:
- 444 × 300 = 133,200

- Add: 133,200 + 4,440 + 888 = 138,528

2. 208 × 287
- Use standard multiplication:
- 208 × 287 = (200 + 8) × 287 = 200×287 + 8×287
- 200×287 = 57,400
- 8×287 = 2,296
- Total = 57,400 + 2,296 = 59,696

3. 125 × 509
- 125 × 500 = 62,500
- 125 × 9 = 1,125
- Total = 62,500 + 1,125 = 63,625

4. 741 × 123
- 741 × 100 = 74,100
- 741 × 20 = 14,820
- 741 × 3 = 2,223
- Total = 74,100 + 14,820 + 2,223 = 91,143

5. 245 × 319
- 245 × 300 = 73,500
- 245 × 10 = 2,450
- 245 × 9 = 2,205
- Total = 73,500 + 2,450 + 2,205 = 78,155

6. 667 × 615
- Use distributive property:
- 667 × 600 = 400,200
- 667 × 15 = 667 × 10 + 667 × 5 = 6,670 + 3,335 = 10,005
- Total = 400,200 + 10,005 = 410,205

- Total = 196,200 + 6,540 + 1,308 = 204,048

11. 551 × 226
- 551 × 200 = 110,200
- 551 × 20 = 11,020
- 551 × 6 = 3,306
- Total = 110,200 + 11,020 + 3,306 = 124,526

12. 399 × 718
- 399 × 700 = 279,300
- 399 × 18 = 399 × 10 + 399 × 8 = 3,990 + 3,192 = 7,182
