Let's get this math done. We have 531 and we're going to multiply it by 11. This is the same as taking 531 and adding it to itself 11 times.
Step 1: 0 + 531 = 531
Step 2: 531 + 531 = 1062
Step 3: 1062 + 531 = 1593
Step 4: 1593 + 531 = 2124
Step 5: 2124 + 531 = 2655
Step 6: 2655 + 531 = 3186
Step 7: 3186 + 531 = 3717
Step 8: 3717 + 531 = 4248
Step 9: 4248 + 531 = 4779
Step 10: 4779 + 531 = 5310
Step 11: 5310 + 531 = 5841

So, 531*11 = 5841
