OK, let's crack this. We're given 663 and our task is to multiply it by 14. Essentially, we'll be adding 663 to itself 14 times.
Step 1: 0 + 663 = 663
Step 2: 663 + 663 = 1326
Step 3: 1326 + 663 = 1989
Step 4: 1989 + 663 = 2652
Step 5: 2652 + 663 = 3315
Step 6: 3315 + 663 = 3978
Step 7: 3978 + 663 = 4641
Step 8: 4641 + 663 = 5304
Step 9: 5304 + 663 = 5967
Step 10: 5967 + 663 = 6630
Step 11: 6630 + 663 = 7293
Step 12: 7293 + 663 = 7956
Step 13: 7956 + 663 = 8619
Step 14: 8619 + 663 = 9282

So, 663*14 = 9282
