Without delay, let's solve this. We've got 522 and we will be multiplying it by 31, that is, adding 522 to itself 31 times.
Step 1: 0 + 522 = 522
Step 2: 522 + 522 = 1044
Step 3: 1044 + 522 = 1566
Step 4: 1566 + 522 = 2088
Step 5: 2088 + 522 = 2610
Step 6: 2610 + 522 = 3132
Step 7: 3132 + 522 = 3654
Step 8: 3654 + 522 = 4176
Step 9: 4176 + 522 = 4698
Step 10: 4698 + 522 = 5220
Step 11: 5220 + 522 = 5742
Step 12: 5742 + 522 = 6264
Step 13: 6264 + 522 = 6786
Step 14: 6786 + 522 = 7308
Step 15: 7308 + 522 = 7830
Step 16: 7830 + 522 = 8352
Step 17: 8352 + 522 = 8874
Step 18: 8874 + 522 = 9396
Step 19: 9396 + 522 = 9918
Step 20: 9918 + 522 = 10440
Step 21: 10440 + 522 = 10962
Step 22: 10962 + 522 = 11484
Step 23: 11484 + 522 = 12006
Step 24: 12006 + 522 = 12528
Step 25: 12528 + 522 = 13050
Step 26: 13050 + 522 = 13572
Step 27: 13572 + 522 = 14094
Step 28: 14094 + 522 = 14616
Step 29: 14616 + 522 = 15138
Step 30: 15138 + 522 = 15660
Step 31: 15660 + 522 = 16182

So, 522*31 = 16182
