Let's get this math done. We have 77 and we're going to multiply it by 8. This is the same as taking 77 and adding it to itself 8 times.
Step 1: 0 + 77 = 77
Step 2: 77 + 77 = 154
Step 3: 154 + 77 = 231
Step 4: 231 + 77 = 308
Step 5: 308 + 77 = 385
Step 6: 385 + 77 = 462
Step 7: 462 + 77 = 539
Step 8: 539 + 77 = 616

So, 77*8 = 616
