OK, let's crack this. We're given 883 and our task is to multiply it by 12. Essentially, we'll be adding 883 to itself 12 times.
Step 1: 0 + 883 = 883
Step 2: 883 + 883 = 1766
Step 3: 1766 + 883 = 2649
Step 4: 2649 + 883 = 3532
Step 5: 3532 + 883 = 4415
Step 6: 4415 + 883 = 5298
Step 7: 5298 + 883 = 6181
Step 8: 6181 + 883 = 7064
Step 9: 7064 + 883 = 7947
Step 10: 7947 + 883 = 8830
Step 11: 8830 + 883 = 9713
Step 12: 9713 + 883 = 10596

So, 883*12 = 10596
