Alright, let's solve this math problem step by step. First, we have the number 453. 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 453 and add it to itself 5 times.
Step 1: 0 + 453 = 453
Step 2: 453 + 453 = 906
Step 3: 906 + 453 = 1359
Step 4: 1359 + 453 = 1812
Step 5: 1812 + 453 = 2265

So, 453*5 = 2265
