Alright, let's solve this math problem step by step. First, we have the number 704. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 13. So, we're going to take the number 704 and add it to itself 13 times.
Step 1: 0 + 704 = 704
Step 2: 704 + 704 = 1408
Step 3: 1408 + 704 = 2112
Step 4: 2112 + 704 = 2816
Step 5: 2816 + 704 = 3520
Step 6: 3520 + 704 = 4224
Step 7: 4224 + 704 = 4928
Step 8: 4928 + 704 = 5632
Step 9: 5632 + 704 = 6336
Step 10: 6336 + 704 = 7040
Step 11: 7040 + 704 = 7744
Step 12: 7744 + 704 = 8448
Step 13: 8448 + 704 = 9152

So, 704*13 = 9152
