OK, let's crack this. We're given 429 and our task is to multiply it by 22. Essentially, we'll be adding 429 to itself 22 times.
Step 1: 0 + 429 = 429
Step 2: 429 + 429 = 858
Step 3: 858 + 429 = 1287
Step 4: 1287 + 429 = 1716
Step 5: 1716 + 429 = 2145
Step 6: 2145 + 429 = 2574
Step 7: 2574 + 429 = 3003
Step 8: 3003 + 429 = 3432
Step 9: 3432 + 429 = 3861
Step 10: 3861 + 429 = 4290
Step 11: 4290 + 429 = 4719
Step 12: 4719 + 429 = 5148
Step 13: 5148 + 429 = 5577
Step 14: 5577 + 429 = 6006
Step 15: 6006 + 429 = 6435
Step 16: 6435 + 429 = 6864
Step 17: 6864 + 429 = 7293
Step 18: 7293 + 429 = 7722
Step 19: 7722 + 429 = 8151
Step 20: 8151 + 429 = 8580
Step 21: 8580 + 429 = 9009
Step 22: 9009 + 429 = 9438

So, 429*22 = 9438
