Without delay, let's solve this. We've got 743 and we will be multiplying it by 16, that is, adding 743 to itself 16 times.
Step 1: 0 + 743 = 743
Step 2: 743 + 743 = 1486
Step 3: 1486 + 743 = 2229
Step 4: 2229 + 743 = 2972
Step 5: 2972 + 743 = 3715
Step 6: 3715 + 743 = 4458
Step 7: 4458 + 743 = 5201
Step 8: 5201 + 743 = 5944
Step 9: 5944 + 743 = 6687
Step 10: 6687 + 743 = 7430
Step 11: 7430 + 743 = 8173
Step 12: 8173 + 743 = 8916
Step 13: 8916 + 743 = 9659
Step 14: 9659 + 743 = 10402
Step 15: 10402 + 743 = 11145
Step 16: 11145 + 743 = 11888

So, 743*16 = 11888
