OK, let's work through this together. We're starting with 493 and we're going to multiply it by 12, which means we add 493 to itself 12 times.
Step 1: 0 + 493 = 493
Step 2: 493 + 493 = 986
Step 3: 986 + 493 = 1479
Step 4: 1479 + 493 = 1972
Step 5: 1972 + 493 = 2465
Step 6: 2465 + 493 = 2958
Step 7: 2958 + 493 = 3451
Step 8: 3451 + 493 = 3944
Step 9: 3944 + 493 = 4437
Step 10: 4437 + 493 = 4930
Step 11: 4930 + 493 = 5423
Step 12: 5423 + 493 = 5916

So, 493*12 = 5916
