Alright, let's solve this math problem step by step. First, we have the number 130. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 4. So, we're going to take the number 130 and add it to itself 4 times.
Step 1: 0 + 130 = 130
Step 2: 130 + 130 = 260
Step 3: 260 + 130 = 390
Step 4: 390 + 130 = 520

So, 130*4 = 520
