Alright, let's solve this math problem step by step. First, we have the number 136. 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 136 and add it to itself 4 times.
Step 1: 0 + 136 = 136
Step 2: 136 + 136 = 272
Step 3: 272 + 136 = 408
Step 4: 408 + 136 = 544

So, 136*4 = 544
