OK, let's work through this together. We're starting with 774 and we're going to multiply it by 12, which means we add 774 to itself 12 times.
Step 1: 0 + 774 = 774
Step 2: 774 + 774 = 1548
Step 3: 1548 + 774 = 2322
Step 4: 2322 + 774 = 3096
Step 5: 3096 + 774 = 3870
Step 6: 3870 + 774 = 4644
Step 7: 4644 + 774 = 5418
Step 8: 5418 + 774 = 6192
Step 9: 6192 + 774 = 6966
Step 10: 6966 + 774 = 7740
Step 11: 7740 + 774 = 8514
Step 12: 8514 + 774 = 9288

So, 774*12 = 9288
