Alright, let's solve this math problem step by step. First, we have the number 604. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 6. So, we're going to take the number 604 and add it to itself 6 times.
Step 1: 0 + 604 = 604
Step 2: 604 + 604 = 1208
Step 3: 1208 + 604 = 1812
Step 4: 1812 + 604 = 2416
Step 5: 2416 + 604 = 3020
Step 6: 3020 + 604 = 3624

So, 604*6 = 3624
