Alright, let's solve this math problem step by step. First, we have the number 880. 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 880 and add it to itself 5 times.
Step 1: 0 + 880 = 880
Step 2: 880 + 880 = 1760
Step 3: 1760 + 880 = 2640
Step 4: 2640 + 880 = 3520
Step 5: 3520 + 880 = 4400

So, 880*5 = 4400
