Without delay, let's solve this. We've got 892 and we will be multiplying it by 31, that is, adding 892 to itself 31 times.
Step 1: 0 + 892 = 892
Step 2: 892 + 892 = 1784
Step 3: 1784 + 892 = 2676
Step 4: 2676 + 892 = 3568
Step 5: 3568 + 892 = 4460
Step 6: 4460 + 892 = 5352
Step 7: 5352 + 892 = 6244
Step 8: 6244 + 892 = 7136
Step 9: 7136 + 892 = 8028
Step 10: 8028 + 892 = 8920
Step 11: 8920 + 892 = 9812
Step 12: 9812 + 892 = 10704
Step 13: 10704 + 892 = 11596
Step 14: 11596 + 892 = 12488
Step 15: 12488 + 892 = 13380
Step 16: 13380 + 892 = 14272
Step 17: 14272 + 892 = 15164
Step 18: 15164 + 892 = 16056
Step 19: 16056 + 892 = 16948
Step 20: 16948 + 892 = 17840
Step 21: 17840 + 892 = 18732
Step 22: 18732 + 892 = 19624
Step 23: 19624 + 892 = 20516
Step 24: 20516 + 892 = 21408
Step 25: 21408 + 892 = 22300
Step 26: 22300 + 892 = 23192
Step 27: 23192 + 892 = 24084
Step 28: 24084 + 892 = 24976
Step 29: 24976 + 892 = 25868
Step 30: 25868 + 892 = 26760
Step 31: 26760 + 892 = 27652

So, 892*31 = 27652
