Let's roll up our sleeves and solve this. We have 897 and we're going to multiply it by 10, essentially adding 897 to itself 10 times.
Step 1: 0 + 897 = 897
Step 2: 897 + 897 = 1794
Step 3: 1794 + 897 = 2691
Step 4: 2691 + 897 = 3588
Step 5: 3588 + 897 = 4485
Step 6: 4485 + 897 = 5382
Step 7: 5382 + 897 = 6279
Step 8: 6279 + 897 = 7176
Step 9: 7176 + 897 = 8073
Step 10: 8073 + 897 = 8970

So, 897*10 = 8970
