OK, let's work through this together. We're starting with 897 and we're going to multiply it by 6, which means we add 897 to itself 6 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

So, 897*6 = 5382
