OK, let's work through this together. We're starting with 582 and we're going to multiply it by 12, which means we add 582 to itself 12 times.
Step 1: 0 + 582 = 582
Step 2: 582 + 582 = 1164
Step 3: 1164 + 582 = 1746
Step 4: 1746 + 582 = 2328
Step 5: 2328 + 582 = 2910
Step 6: 2910 + 582 = 3492
Step 7: 3492 + 582 = 4074
Step 8: 4074 + 582 = 4656
Step 9: 4656 + 582 = 5238
Step 10: 5238 + 582 = 5820
Step 11: 5820 + 582 = 6402
Step 12: 6402 + 582 = 6984

So, 582*12 = 6984
