Sure thing! We've got 945 and we're gonna multiply it by 9. That's the same as adding 945 to itself 9 times.
Step 1: 0 + 945 = 945
Step 2: 945 + 945 = 1890
Step 3: 1890 + 945 = 2835
Step 4: 2835 + 945 = 3780
Step 5: 3780 + 945 = 4725
Step 6: 4725 + 945 = 5670
Step 7: 5670 + 945 = 6615
Step 8: 6615 + 945 = 7560
Step 9: 7560 + 945 = 8505

So, 945*9 = 8505
