Let's roll up our sleeves and solve this. We have 388 and we're going to multiply it by 8, essentially adding 388 to itself 8 times.
Step 1: 0 + 388 = 388
Step 2: 388 + 388 = 776
Step 3: 776 + 388 = 1164
Step 4: 1164 + 388 = 1552
Step 5: 1552 + 388 = 1940
Step 6: 1940 + 388 = 2328
Step 7: 2328 + 388 = 2716
Step 8: 2716 + 388 = 3104

So, 388*8 = 3104
