I'll solve each multiplication problem step by step.
Let me work through all 9 problems:
Problem 1: 234 × 12
- 234 × 2 = 468
- 234 × 10 = 2,340
- 468 + 2,340 = 2,808
Problem 2: 432 × 21
- 432 × 1 = 432
- 432 × 20 = 8,640
- 432 + 8,640 = 9,072
Problem 3: 324 × 11
- 324 × 1 = 324
- 324 × 10 = 3,240
- 324 + 3,240 = 3,564
Problem 4: 622 × 31
- 622 × 1 = 622
- 622 × 30 = 18,660
- 622 + 18,660 = 19,282
Problem 5: 135 × 21
- 135 × 1 = 135
- 135 × 20 = 2,700
- 135 + 2,700 = 2,835
Problem 6: 531 × 22
- 531 × 2 = 1,062
- 531 × 20 = 10,620
- 1,062 + 10,620 = 11,682
Problem 7: 721 × 13
- 721 × 3 = 2,163
- 721 × 10 = 7,210
- 2,163 + 7,210 = 9,373
Problem 8: 421 × 31
- 421 × 1 = 421
- 421 × 30 = 12,630
- 421 + 12,630 = 13,051
Problem 9: 231 × 32
- 231 × 2 = 462
- 231 × 30 = 6,930
- 462 + 6,930 = 7,392
Final Answer:
234 × 12 = 2,808
432 × 21 = 9,072
324 × 11 = 3,564
