OK, let's crack this. We're given 445 and our task is to multiply it by 10. Essentially, we'll be adding 445 to itself 10 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
Step 10: 4005 + 445 = 4450

So, 445*10 = 4450
