Without delay, let's solve this. We've got 171 and we will be multiplying it by 16, that is, adding 171 to itself 16 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

So, 171*16 = 2736
