OK, let's crack this. We're given 171 and our task is to multiply it by 48. Essentially, we'll be adding 171 to itself 48 times.
Step 1: 0 + 171 = 171
Step 2: 171 + 171 = 342
Step 3: 342 + 171 = 513
Step 4: 513 + 171 = 684
Step 5: 684 + 171 = 855
Step 6: 855 + 171 = 1026
Step 7: 1026 + 171 = 1197
Step 8: 1197 + 171 = 1368
Step 9: 1368 + 171 = 1539
Step 10: 1539 + 171 = 1710
Step 11: 1710 + 171 = 1881
Step 12: 1881 + 171 = 2052
Step 13: 2052 + 171 = 2223
Step 14: 2223 + 171 = 2394
Step 15: 2394 + 171 = 2565
Step 16: 2565 + 171 = 2736
Step 17: 2736 + 171 = 2907
Step 18: 2907 + 171 = 3078
Step 19: 3078 + 171 = 3249
Step 20: 3249 + 171 = 3420
Step 21: 3420 + 171 = 3591
Step 22: 3591 + 171 = 3762
Step 23: 3762 + 171 = 3933
Step 24: 3933 + 171 = 4104
Step 25: 4104 + 171 = 4275
Step 26: 4275 + 171 = 4446
Step 27: 4446 + 171 = 4617
Step 28: 4617 + 171 = 4788
Step 29: 4788 + 171 = 4959
Step 30: 4959 + 171 = 5130
Step 31: 5130 + 171 = 5301
Step 32: 5301 + 171 = 5472
Step 33: 5472 + 171 = 5643
Step 34: 5643 + 171 = 5814
Step 35: 5814 + 171 = 5985
Step 36: 5985 + 171 = 6156
Step 37: 6156 + 171 = 6327
Step 38: 6327 + 171 = 6498
Step 39: 6498 + 171 = 6669
Step 40: 6669 + 171 = 6840
Step 41: 6840 + 171 = 7011
Step 42: 7011 + 171 = 7182
Step 43: 7182 + 171 = 7353
Step 44: 7353 + 171 = 7524
Step 45: 7524 + 171 = 7695
Step 46: 7695 + 171 = 7866
Step 47: 7866 + 171 = 8037
Step 48: 8037 + 171 = 8208

So, 171*48 = 8208
