Let's get this math done. We have 491 and we're going to multiply it by 11. This is the same as taking 491 and adding it to itself 11 times.
Step 1: 0 + 491 = 491
Step 2: 491 + 491 = 982
Step 3: 982 + 491 = 1473
Step 4: 1473 + 491 = 1964
Step 5: 1964 + 491 = 2455
Step 6: 2455 + 491 = 2946
Step 7: 2946 + 491 = 3437
Step 8: 3437 + 491 = 3928
Step 9: 3928 + 491 = 4419
Step 10: 4419 + 491 = 4910
Step 11: 4910 + 491 = 5401

So, 491*11 = 5401
