Let's get this math done. We have 71 and we're going to multiply it by 8. This is the same as taking 71 and adding it to itself 8 times.
Step 1: 0 + 71 = 71
Step 2: 71 + 71 = 142
Step 3: 142 + 71 = 213
Step 4: 213 + 71 = 284
Step 5: 284 + 71 = 355
Step 6: 355 + 71 = 426
Step 7: 426 + 71 = 497
Step 8: 497 + 71 = 568

So, 71*8 = 568
