Let's get this math done. We have 388 and we're going to multiply it by 11. This is the same as taking 388 and adding it to itself 11 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
Step 9: 3104 + 388 = 3492
Step 10: 3492 + 388 = 3880
Step 11: 3880 + 388 = 4268

So, 388*11 = 4268
