Let's roll up our sleeves and solve this. We have 462 and we're going to multiply it by 9, essentially adding 462 to itself 9 times.
Step 1: 0 + 462 = 462
Step 2: 462 + 462 = 924
Step 3: 924 + 462 = 1386
Step 4: 1386 + 462 = 1848
Step 5: 1848 + 462 = 2310
Step 6: 2310 + 462 = 2772
Step 7: 2772 + 462 = 3234
Step 8: 3234 + 462 = 3696
Step 9: 3696 + 462 = 4158

So, 462*9 = 4158
