OK, let's work through this together. We're starting with 499 and we're going to multiply it by 12, which means we add 499 to itself 12 times.
Step 1: 0 + 499 = 499
Step 2: 499 + 499 = 998
Step 3: 998 + 499 = 1497
Step 4: 1497 + 499 = 1996
Step 5: 1996 + 499 = 2495
Step 6: 2495 + 499 = 2994
Step 7: 2994 + 499 = 3493
Step 8: 3493 + 499 = 3992
Step 9: 3992 + 499 = 4491
Step 10: 4491 + 499 = 4990
Step 11: 4990 + 499 = 5489
Step 12: 5489 + 499 = 5988

So, 499*12 = 5988
