Alright, let's solve this math problem step by step. First, we have the number 756. 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 756 and add it to itself 5 times.
Step 1: 0 + 756 = 756
Step 2: 756 + 756 = 1512
Step 3: 1512 + 756 = 2268
Step 4: 2268 + 756 = 3024
Step 5: 3024 + 756 = 3780

So, 756*5 = 3780
