Without delay, let's solve this. We've got 712 and we will be multiplying it by 8, that is, adding 712 to itself 8 times.
Step 1: 0 + 712 = 712
Step 2: 712 + 712 = 1424
Step 3: 1424 + 712 = 2136
Step 4: 2136 + 712 = 2848
Step 5: 2848 + 712 = 3560
Step 6: 3560 + 712 = 4272
Step 7: 4272 + 712 = 4984
Step 8: 4984 + 712 = 5696

So, 712*8 = 5696
