Alright, let's solve this math problem step by step. First, we have the number 709. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 9. So, we're going to take the number 709 and add it to itself 9 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
Step 9: 5672 + 709 = 6381

So, 709*9 = 6381
