OK, let's crack this. We're given 892 and our task is to multiply it by 12. Essentially, we'll be adding 892 to itself 12 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

So, 892*12 = 10704
