OK, let's work through this together. We're starting with 414 and we're going to multiply it by 12, which means we add 414 to itself 12 times.
Step 1: 0 + 414 = 414
Step 2: 414 + 414 = 828
Step 3: 828 + 414 = 1242
Step 4: 1242 + 414 = 1656
Step 5: 1656 + 414 = 2070
Step 6: 2070 + 414 = 2484
Step 7: 2484 + 414 = 2898
Step 8: 2898 + 414 = 3312
Step 9: 3312 + 414 = 3726
Step 10: 3726 + 414 = 4140
Step 11: 4140 + 414 = 4554
Step 12: 4554 + 414 = 4968

So, 414*12 = 4968
