Alright, let's solve this math problem step by step. First, we have the number 451. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 8. So, we're going to take the number 451 and add it to itself 8 times.
Step 1: 0 + 451 = 451
Step 2: 451 + 451 = 902
Step 3: 902 + 451 = 1353
Step 4: 1353 + 451 = 1804
Step 5: 1804 + 451 = 2255
Step 6: 2255 + 451 = 2706
Step 7: 2706 + 451 = 3157
Step 8: 3157 + 451 = 3608

So, 451*8 = 3608
