Let's roll up our sleeves and solve this. We have 468 and we're going to multiply it by 9, essentially adding 468 to itself 9 times.
Step 1: 0 + 468 = 468
Step 2: 468 + 468 = 936
Step 3: 936 + 468 = 1404
Step 4: 1404 + 468 = 1872
Step 5: 1872 + 468 = 2340
Step 6: 2340 + 468 = 2808
Step 7: 2808 + 468 = 3276
Step 8: 3276 + 468 = 3744
Step 9: 3744 + 468 = 4212

So, 468*9 = 4212
