OK, let's work through this together. We're starting with 83 and we're going to multiply it by 12, which means we add 83 to itself 12 times.
Step 1: 0 + 83 = 83
Step 2: 83 + 83 = 166
Step 3: 166 + 83 = 249
Step 4: 249 + 83 = 332
Step 5: 332 + 83 = 415
Step 6: 415 + 83 = 498
Step 7: 498 + 83 = 581
Step 8: 581 + 83 = 664
Step 9: 664 + 83 = 747
Step 10: 747 + 83 = 830
Step 11: 830 + 83 = 913
Step 12: 913 + 83 = 996

So, 83*12 = 996
