OK, let's work through this together. We're starting with 738 and we're going to multiply it by 8, which means we add 738 to itself 8 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

So, 738*8 = 5904
