OK, let's work through this together. We're starting with 709 and we're going to multiply it by 8, which means we add 709 to itself 8 times.
Step 1: 0 + 709 = 709
Step 2: 709 + 709 = 1418
Step 3: 1418 + 709 = 2127
Step 4: 2127 + 709 = 2836
Step 5: 2836 + 709 = 3545
Step 6: 3545 + 709 = 4254
Step 7: 4254 + 709 = 4963
Step 8: 4963 + 709 = 5672

So, 709*8 = 5672
