Sure thing, let's get straight to it. We start with 433 and we're going to multiply it by 42, which means adding 433 to itself 42 times.
Step 1: 0 + 433 = 433
Step 2: 433 + 433 = 866
Step 3: 866 + 433 = 1299
Step 4: 1299 + 433 = 1732
Step 5: 1732 + 433 = 2165
Step 6: 2165 + 433 = 2598
Step 7: 2598 + 433 = 3031
Step 8: 3031 + 433 = 3464
Step 9: 3464 + 433 = 3897
Step 10: 3897 + 433 = 4330
Step 11: 4330 + 433 = 4763
Step 12: 4763 + 433 = 5196
Step 13: 5196 + 433 = 5629
Step 14: 5629 + 433 = 6062
Step 15: 6062 + 433 = 6495
Step 16: 6495 + 433 = 6928
Step 17: 6928 + 433 = 7361
Step 18: 7361 + 433 = 7794
Step 19: 7794 + 433 = 8227
Step 20: 8227 + 433 = 8660
Step 21: 8660 + 433 = 9093
Step 22: 9093 + 433 = 9526
Step 23: 9526 + 433 = 9959
Step 24: 9959 + 433 = 10392
Step 25: 10392 + 433 = 10825
Step 26: 10825 + 433 = 11258
Step 27: 11258 + 433 = 11691
Step 28: 11691 + 433 = 12124
Step 29: 12124 + 433 = 12557
Step 30: 12557 + 433 = 12990
Step 31: 12990 + 433 = 13423
Step 32: 13423 + 433 = 13856
Step 33: 13856 + 433 = 14289
Step 34: 14289 + 433 = 14722
Step 35: 14722 + 433 = 15155
Step 36: 15155 + 433 = 15588
Step 37: 15588 + 433 = 16021
Step 38: 16021 + 433 = 16454
Step 39: 16454 + 433 = 16887
Step 40: 16887 + 433 = 17320
Step 41: 17320 + 433 = 17753
Step 42: 17753 + 433 = 18186

So, 433*42 = 18186
