Sure thing! We've got 647 and we're gonna multiply it by 10. That's the same as adding 647 to itself 10 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
Step 10: 5823 + 647 = 6470

So, 647*10 = 6470
