Let's get this math done. We have 445 and we're going to multiply it by 9. This is the same as taking 445 and adding it to itself 9 times.
Step 1: 0 + 445 = 445
Step 2: 445 + 445 = 890
Step 3: 890 + 445 = 1335
Step 4: 1335 + 445 = 1780
Step 5: 1780 + 445 = 2225
Step 6: 2225 + 445 = 2670
Step 7: 2670 + 445 = 3115
Step 8: 3115 + 445 = 3560
Step 9: 3560 + 445 = 4005

So, 445*9 = 4005
