Let's roll up our sleeves and solve this. We have 785 and we're going to multiply it by 12, essentially adding 785 to itself 12 times.
Step 1: 0 + 785 = 785
Step 2: 785 + 785 = 1570
Step 3: 1570 + 785 = 2355
Step 4: 2355 + 785 = 3140
Step 5: 3140 + 785 = 3925
Step 6: 3925 + 785 = 4710
Step 7: 4710 + 785 = 5495
Step 8: 5495 + 785 = 6280
Step 9: 6280 + 785 = 7065
Step 10: 7065 + 785 = 7850
Step 11: 7850 + 785 = 8635
Step 12: 8635 + 785 = 9420

So, 785*12 = 9420
