Without delay, let's solve this. We've got 570 and we will be multiplying it by 8, that is, adding 570 to itself 8 times.
Step 1: 0 + 570 = 570
Step 2: 570 + 570 = 1140
Step 3: 1140 + 570 = 1710
Step 4: 1710 + 570 = 2280
Step 5: 2280 + 570 = 2850
Step 6: 2850 + 570 = 3420
Step 7: 3420 + 570 = 3990
Step 8: 3990 + 570 = 4560

So, 570*8 = 4560
