Sure thing! We've got 723 and we're gonna multiply it by 12. That's the same as adding 723 to itself 12 times.
Step 1: 0 + 723 = 723
Step 2: 723 + 723 = 1446
Step 3: 1446 + 723 = 2169
Step 4: 2169 + 723 = 2892
Step 5: 2892 + 723 = 3615
Step 6: 3615 + 723 = 4338
Step 7: 4338 + 723 = 5061
Step 8: 5061 + 723 = 5784
Step 9: 5784 + 723 = 6507
Step 10: 6507 + 723 = 7230
Step 11: 7230 + 723 = 7953
Step 12: 7953 + 723 = 8676

So, 723*12 = 8676
