Let's roll up our sleeves and solve this. We have 478 and we're going to multiply it by 12, essentially adding 478 to itself 12 times.
Step 1: 0 + 478 = 478
Step 2: 478 + 478 = 956
Step 3: 956 + 478 = 1434
Step 4: 1434 + 478 = 1912
Step 5: 1912 + 478 = 2390
Step 6: 2390 + 478 = 2868
Step 7: 2868 + 478 = 3346
Step 8: 3346 + 478 = 3824
Step 9: 3824 + 478 = 4302
Step 10: 4302 + 478 = 4780
Step 11: 4780 + 478 = 5258
Step 12: 5258 + 478 = 5736

So, 478*12 = 5736
