OK, let's crack this. We're given 738 and our task is to multiply it by 16. Essentially, we'll be adding 738 to itself 16 times.
Step 1: 0 + 738 = 738
Step 2: 738 + 738 = 1476
Step 3: 1476 + 738 = 2214
Step 4: 2214 + 738 = 2952
Step 5: 2952 + 738 = 3690
Step 6: 3690 + 738 = 4428
Step 7: 4428 + 738 = 5166
Step 8: 5166 + 738 = 5904
Step 9: 5904 + 738 = 6642
Step 10: 6642 + 738 = 7380
Step 11: 7380 + 738 = 8118
Step 12: 8118 + 738 = 8856
Step 13: 8856 + 738 = 9594
Step 14: 9594 + 738 = 10332
Step 15: 10332 + 738 = 11070
Step 16: 11070 + 738 = 11808

So, 738*16 = 11808
