OK, let's crack this. We're given 151 and our task is to multiply it by 8. Essentially, we'll be adding 151 to itself 8 times.
Step 1: 0 + 151 = 151
Step 2: 151 + 151 = 302
Step 3: 302 + 151 = 453
Step 4: 453 + 151 = 604
Step 5: 604 + 151 = 755
Step 6: 755 + 151 = 906
Step 7: 906 + 151 = 1057
Step 8: 1057 + 151 = 1208

So, 151*8 = 1208
