Sure thing, let's get straight to it. We start with 647 and we're going to multiply it by 9, which means adding 647 to itself 9 times.
Step 1: 0 + 647 = 647
Step 2: 647 + 647 = 1294
Step 3: 1294 + 647 = 1941
Step 4: 1941 + 647 = 2588
Step 5: 2588 + 647 = 3235
Step 6: 3235 + 647 = 3882
Step 7: 3882 + 647 = 4529
Step 8: 4529 + 647 = 5176
Step 9: 5176 + 647 = 5823

So, 647*9 = 5823
