Alright, let's solve this math problem step by step. First, we have the number 457. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 14. So, we're going to take the number 457 and add it to itself 14 times.
Step 1: 0 + 457 = 457
Step 2: 457 + 457 = 914
Step 3: 914 + 457 = 1371
Step 4: 1371 + 457 = 1828
Step 5: 1828 + 457 = 2285
Step 6: 2285 + 457 = 2742
Step 7: 2742 + 457 = 3199
Step 8: 3199 + 457 = 3656
Step 9: 3656 + 457 = 4113
Step 10: 4113 + 457 = 4570
Step 11: 4570 + 457 = 5027
Step 12: 5027 + 457 = 5484
Step 13: 5484 + 457 = 5941
Step 14: 5941 + 457 = 6398

So, 457*14 = 6398
