Alright, let's solve this math problem step by step. First, we have the number 111. 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 111 and add it to itself 5 times.
Step 1: 0 + 111 = 111
Step 2: 111 + 111 = 222
Step 3: 222 + 111 = 333
Step 4: 333 + 111 = 444
Step 5: 444 + 111 = 555

So, 111*5 = 555
