Alright, let's solve this math problem step by step. First, we have the number 452. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 7. So, we're going to take the number 452 and add it to itself 7 times.
Step 1: 0 + 452 = 452
Step 2: 452 + 452 = 904
Step 3: 904 + 452 = 1356
Step 4: 1356 + 452 = 1808
Step 5: 1808 + 452 = 2260
Step 6: 2260 + 452 = 2712
Step 7: 2712 + 452 = 3164

So, 452*7 = 3164
