Sure thing, let's get straight to it. We start with 791 and we're going to multiply it by 12, which means adding 791 to itself 12 times.
Step 1: 0 + 791 = 791
Step 2: 791 + 791 = 1582
Step 3: 1582 + 791 = 2373
Step 4: 2373 + 791 = 3164
Step 5: 3164 + 791 = 3955
Step 6: 3955 + 791 = 4746
Step 7: 4746 + 791 = 5537
Step 8: 5537 + 791 = 6328
Step 9: 6328 + 791 = 7119
Step 10: 7119 + 791 = 7910
Step 11: 7910 + 791 = 8701
Step 12: 8701 + 791 = 9492

So, 791*12 = 9492
