Alright, let's solve this math problem step by step. First, we have the number 77. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 5. So, we're going to take the number 77 and add it to itself 5 times.
Step 1: 0 + 77 = 77
Step 2: 77 + 77 = 154
Step 3: 154 + 77 = 231
Step 4: 231 + 77 = 308
Step 5: 308 + 77 = 385

So, 77*5 = 385
