Step 1: 0 + 586 = 586
Step 2: 586 + 586 = 1172
Step 3: 1172 + 586 = 1758
Step 4: 1758 + 586 = 2344
Step 5: 2344 + 586 = 2930
Step 6: 2930 + 586 = 3516
Step 7: 3516 + 586 = 4102
Step 8: 4102 + 586 = 4688
Step 9: 4688 + 586 = 5274
Step 10: 5274 + 586 = 5860
Step 11: 5860 + 586 = 6446
Step 12: 6446 + 586 = 7032
Step 13: 7032 + 586 = 7618
Step 14: 7618 + 586 = 8204
Step 15: 8204 + 586 = 8790
Step 16: 8790 + 586 = 9376
Step 17: 9376 + 586 = 9962
Step 18: 9962 + 586 = 10548
Step 19: 10548 + 586 = 11134
Step 20: 11134 + 586 = 11720
Step 21: 11720 + 586 = 12306
Step 22: 12306 + 586 = 12892
Step 23: 12892 + 586 = 13478
Step 24: 13478 + 586 = 14064
Step 25: 14064 + 586 = 14650
Step 26: 14650 + 586 = 15236
Step 27: 15236 + 586 = 15822
Step 28: 15822 + 586 = 16408
Step 29: 16408 + 586 = 16994
Step 30: 16994 + 586 = 17580
Step 31: 17580 + 586 = 18166

So, 586*31 = 18166
